DETAILED DESCRIPTION
Hereinafter, the embodiments of the present application will be described in detail with reference to the accompanying drawings.
First, a display device according to an embodiment of the present application will be described with reference to FIGS. 1 to 9B . The display device according to an embodiment of the present application may be a display device such as a liquid crystal display, an LED display, a plasma display or the like to which a drive signal needs to be provided.
FIG. 1 is a structural block diagram briefly illustrating a display device according to an embodiment of present application. As shown in FIG. 1 , the display device 1 comprises an array of display cells 10 , a plurality of first type of drive lines 20 , a plurality of second type of drive lines 30 , and a display drive unit 40 . Specifically, the array of display cells 10 comprises a plurality of display subunits 10 11 . . . 10 nn . As can be readily appreciated, the array of display cells 10 composed by a plurality of display subunits as shown in FIG. 1 is merely illustrative, wherein the number of the plurality of display subunits and their specific layout may vary depending on the design and use requirements. Each ( 20 1 . . . 20 n ) of the plurality of first type of drive lines 20 intersects with each ( 30 1 . . . 30 n ) of the plurality of second type of drive lines 30 , intersection thereof corresponds to each display subunit of the plurality of display subunits ( 10 11 . . . 10 nn ), to provide a display drive signal for each display subunit. The display drive unit 40 is connected with the plurality of first type of drive lines and the plurality of second type of drive lines, to provide a display drive signal for the plurality of first type of drive lines and the plurality of second type of drive lines.
Different than the configuration manner that a plurality of first type of drive lines and a plurality of second type of drive lines are connected respectively to a horizontal drive unit and a vertical drive unit in the related art, the display device according to an embodiment of the present application may comprise only a single display drive unit 40 , thereby wiring space needed for arranging the display drive unit is saved and design complexity is simplified. Specific configurations of the display devices according to the first to fifth embodiments of the present application will be further described below with reference to FIGS. 2 to 6B .
FIG. 2 is a schematic diagram illustrating a display device according to a first embodiment of the present application. In the display device 2 according to the first embodiment of the present application, at least one drive line of at least one type of drive lines of the plurality of first type of drive lines and the plurality of second type of drive lines is a curve. As shown in FIG. 2 , each ( 20 1 . . . 20 n ) of the plurality of first type of drive lines 20 is a curve, and each ( 30 1 . . . 30 n ) of the plurality of second type of drive lines 30 is a straight line. As can be readily appreciated, the number of the drive lines and the wiring manner as shown in FIG. 2 are merely illustrative, the display device according to an embodiment of the present application is not limited thereto. In another embodiment of the present application, it is allowed that the plurality of second type of drive lines ( 30 1 . . . 30 n ) are a curve, or alternatively, each or more drive lines among the plurality of first type of drive lines ( 20 1 . . . 20 n ) and the plurality of second type of drive lines ( 30 1 . . . 30 n ) are a curve.
As shown in FIG. 2 , edge of a visible area of the display device 2 is divided into two portions, edge of the visible area corresponding to the plurality of first type of drive lines and the plurality of second type of drive lines connected with the display drive unit 40 is located in a first portion of the two portions, that is, the edge portion shown with a bolded line in FIG. 2 , whereas edge of the visible area where the plurality of first type of drive lines and the plurality of second type of drive lines connected with the display drive unit 40 are not arranged is the second portion. In the embodiment shown in FIG. 2 , the first portion and the second portion have two intersection points, that is, the first portion and the second portion are two separate continuous edge areas, respectively, only intersect at their respective endpoints. As can be readily appreciated, coverage of the present application is not limited thereto, the first portion and the second portion may be divided into a plurality of sub-portions, respectively, the plurality of sub-portions of the first portion and the second portion may be alternately distributed as shown below with reference to FIGS. 5A to 7B . Since the plurality of first type of drive lines ( 20 1 . . . 20 n ) are a curve, so that edge of the first portion may tend to cluster. That is, an edge length of the visible area corresponding to the first portion is less than 50% of a total edge length of the visible area. For example, in the example shown in FIG. 2 , an edge length of the visible area corresponding to the first portion where drive lines are provided is ⅓ of a total edge length of the visible area. Thus, the display device 2 can be provided with a larger edge area that needs no drive line wiring, which thereby facilitates further narrowing the frame of the display device 2 . That is, in an electronic apparatus where the display device 2 according to an embodiment of the present application is configured, the display device 2 may adapt to the shape of the electronic apparatus as needed. Specifically, by adopting the configuration that at least one drive line of at least one type of drive lines of the plurality of first type of drive lines and the plurality of second type of drive lines is a curve, it is possible to bent the drive lines towards the edge of the display device that adapts to wiring based on the shape of the electronic apparatus, and select not to configure wiring at the edge having no wiring space of the display device based on the shape of the electronic apparatus. Herein, the edge having no wiring space of the display device may be an edge where the edge of the display device substantially overlaps with the outer frame of the electronic apparatus per se. Alternatively, the edge having no wiring space of the display device may be an edge of the electronic apparatus where the outer frame thereof is of an irregular shape and thus is inconvenient for wiring.
In addition, as shown in FIG. 2 , curve shape of the drive lines matches with shape of the edge of the display device. In the display device 2 as shown in FIG. 2 , shape of the edge of the display device 2 is an ellipse. As can be readily appreciated, depending on application requirements, the shape of the edge of the display device according to an embodiment of the present application is not limited to ellipse, instead it may be a variety of regular shapes like circle or irregular shapes. The shape of the drive lines being a curve can implement better matching with the edge of the display device, which is a variety of regular or irregular shapes.
Specifically, the plurality of first type of drive lines ( 20 1 . . . 20 n ) which are curves have the same curvature as the corresponding edge of the display device 2 . In particular, in the example shown in FIG. 2 , the plurality of first type of drive lines ( 20 1 . . . 20 n ) and part of the edge of the display device 2 form a curve group having the same circle center and radial outward to the outer center layer by layer, wherein part of the edge of the display device 2 is the outermost edge of the concentric nested curve group. Then the plurality of second type of drive lines ( 30 1 . . . 30 n ) may approximately be a plurality of straight lines radiated radially outward from the circle center. Extension lines of the plurality of second type of drive lines ( 30 1 . . . 30 n ) will intersect at the circle center. Further, the plurality of second type of drive lines ( 30 1 . . . 30 n ) may be divided into two groups symmetrical with respect to a center cross-section of the display device 2 , for example, drive lines 30 1 , 30 2 , 30 3 , and drive lines 30 n−2 , 30 n−1 , 30 n .
In addition, as shown in FIG. 2 , the plurality of first type of drive lines ( 20 1 . . . 20 n ) are projected as a plurality of curves arranged equidistantly on a plane vertical to a display direction of the array of display cells. In an embodiment of the present application, a surface where the array of display cells resides probably has fluctuation according to the shape of the electronic apparatus to which it is applied. For example, when the display device is applied to a dial of a smart watch which is a convex surface, the surface where the array of display cells resides may be a convex surface corresponding to the dial. The direction of the convex outwardly facing the user is the display direction of the array of display cells, the plurality of first type of drive lines ( 20 1 . . . 20 n ) are projected as a plurality of curves arranged equidistantly on a plane vertical to the display direction.
FIG. 3 is a schematic diagram illustrating a display device according to a second embodiment of the present application. In the display device 3 according to a second embodiment of the present application, each ( 20 1 . . . 20 n ) of the plurality of first type of drive lines 20 and each of ( 30 1 . . . 30 n ) the plurality of second type of drive lines 30 is a curve. Specifically, similar to what is shown in FIG. 2 , the plurality of first type of drive lines ( 20 1 . . . 20 n ) and part of the edge of the display device 3 form a curve group having the same circle center and radial outward to the outer center layer by layer, wherein part of the edge of the display device 3 is the outermost edge of the concentric nested curve group. The plurality of second type of drive lines ( 30 1 . . . 30 n ) are approximately divided into two groups symmetrical with respect to a center cross-section of the display device 3 , for example, drive lines 30 1 , 30 2 , 30 3 , and drive lines 30 n−2 , 30 n−1 , 30 n , wherein each group of drive lines ( 30 1 , 30 2 , 30 3 ) or ( 30 n−2 , 30 n−1 , 30 n ) are a portion of a group of inscribed circles that are nested mutually and have a common tangent point.
Accordingly, as compared with the display device 2 according to the first embodiment of the present application as shown in FIG. 2 , by configuring all the plurality of first type of drive lines 20 and the plurality of second type of drive lines 30 as curves, it is possible to further reduce an edge length of the visible area corresponding to the first portion where the drive lines are provided. For example, in the example shown in FIG. 3 , an edge length of the visible area corresponding to the first portion where the drive lines are provided is ¼ of a total edge length of the visible area.
FIG. 4 is a schematic diagram illustrating a display device according to a third embodiment of the present application. In the display device 4 according to the third embodiment of the present application, each ( 20 1 . . . 20 n ) of the plurality of first type of drive lines 20 forms a circle, and each of ( 30 1 . . . 30 n ) the plurality of second type of drive lines 30 is a straight line. Specifically, in the example shown in FIG. 4 , the plurality of first type of drive lines ( 20 1 . . . 20 n ) are a group of concentric circles nested concentrically with the edge of the display device 4 , wherein the edge of the display device 4 is the outermost edge of the group of concentric circles. Then the plurality of second type of drive lines ( 30 1 . . . 30 n ) may approximately be a plurality of straight lines radiated outward from the common circle center of the concentric circles, the plurality of straight lines are the plurality of straight lines of the outermost circle. Accordingly, as compared with the display device 2 according to the first embodiment of the present application as shown in FIG. 2 and the display device 3 according to the second embodiment of the present application as shown in FIG. 3 , by configuring all the plurality of first type of drive lines 20 as circle, it is possible to make the wiring of the drive lines perfectly adapt to the circular outer frame of the display device.
FIGS. 5A to 5C are a top surface vie(a bottom surface view, and a side view illustrating a display device according to a fourth embodiment of the present application. Specifically, FIG. 5A is a top surface view illustrating a display device according to the fourth embodiment of the present application. As can be readily appreciated, the number of the drive lines and the wiring manner as shown in FIG. 5A are merely illustrative, the display device according to an embodiment of the present application is not limited thereto. As shown in FIG. 5A , the plurality of first type of drive lines and the plurality of second type of drive lines are divided into a plurality of groups of drive lines (four groups as shown in FIG. 5A ). As can be seen from FIG. 5A , by adopting such grouped wiring manner, the wiring area at the edge of the display device tends to cluster, which thereby facilitates further narrowing the frame of the display device. That is to say, in an electronic apparatus where the display device according to an embodiment of the present application is configured, the display device can adapt to the shape of the electronic apparatus as needed. Specifically, by adopting grouped configuration for the wiring of the display device, it is possible to select the edge of the display device that adapt to wiring based on the shape of the electronic apparatus as the area where wiring groups are configured, and select not to configure wiring at the edge having no wiring space of the display device based on the shape of the electronic apparatus. Herein, the edge having no wiring space of the display device may be an edge where the edge of the display device substantially overlaps with the outer frame of the electronic apparatus per se. Alternatively, the edge of having no wiring space the display device may be an edge of the electronic apparatus where the outer frame thereof is of an irregular shape and thus is inconvenient for wiring. Detailed examples will be described below with reference to the drawings.
Further, FIG. 5B is a bottom surface view illustrating a display device according to the fourth embodiment of the present application. As shown in FIG. 5B , the display device 5 further comprises a plurality of line concentrating units 50 , each group of the plurality of groups of drive lines, into which the plurality of first type of drive lines and the plurality of second type of drive lines are divided, is connected to the display drive unit 40 via one of the line concentrating units 50 , number of input terminals of one of the line concentrating units 50 connected with each group of the at least two groups of drive lines is M, number of output terminals connected to the display drive unit 40 is N, and M>N. In the embodiment shown in FIG. 5B , number of the input terminals by which one of the line concentrating units 50 and one group of drive lines are connected is three, and number of the output terminals connected to the display drive unit 40 is two. Adopting such wiring manner of connecting the display drive unit via the line concentrating unit after grouping, it is possible to further reduce the number of wiring needed for executing display drive. As can be readily appreciated, the display device according to an embodiment of the present application is not limited thereto, instead, the grouped group of drive lines may be directly connected to the display drive unit 40 without the line concentrating unit 50 .
Furthermore, FIG. 5C is a side view illustrating a display device according to the fourth embodiment of the present application. As shown in FIG. 5C , a side of the surface where the array of display cells 10 residues is a visible side, and at least a portion of the plurality of first type of drive lines 20 and the plurality of second type of drive lines 30 and the display drive unit 40 are provided at the other side of the surface. In particular, the display drive unit 40 is located at a bottom surface 70 of the display device 5 , the display device 5 further comprises a side surface 60 that connects an edge of the surface where the array of display cells 10 residues and the bottom surface 70 , the plurality of first type of drive lines 20 and the plurality of second type of drive lines 30 are provided along the side surface 60 . In the side view as shown in FIG. 5C , a distance from a projection, on a plane vertical to the visible direction (that is, the bottom surface 70 ), of part of the plurality of first type of drive lines 20 and the plurality of second type of drive lines 30 on the surface where the array of display cells 10 residues to the edge of the surface where the array of display cells 10 residues is L. The distance L meets being less than a predetermined threshold. The predetermined threshold may be set as needed by design and display requirements, for example, it may be set as ten mm, five mm, or one mm. Even in the case of grouped wiring, the distance L may be zero. That is to say, at the edge where the drive lines do not turn downward to connect the display drive unit 40 , it is possible that there is no wiring for the drive lines, and at the edge of this portion, the frame other than the visible area on the surface where the array of display cells residues is the narrowest.
FIGS. 6A and 6B are schematic diagrams illustrating a display device according to a fifth embodiment of the present application. In the display devices 6 A and 6 B according to the fifth embodiment of the present application, each group into which the plurality of first drive lines and the plurality of second drive lines are divided may comprise only the first type of drive lines or the second type of drive lines, or each group into which the plurality of first drive lines and the plurality of second drive lines are divided may comprise the first type of drive lines and the second type of drive lines. Specifically, as shown in FIG. 6A , in the display device 6 A according to the fifth embodiment of the present application, each group into which the plurality of first drive lines and the plurality of second drive lines are divided may comprise only the first type of drive lines (the group composed by 20 1 , 20 2 , 20 3 and the group composed by 20 n−2 , 20 n−1 , 20 n ) or the second type of drive lines (the group composed by 30 1 , 30 2 , 30 3 and the group composed by 30 n−2 , 30 n−1 , 30 n ). In contrast, as shown in FIG. 6B , in the display device 6 B according to the fifth embodiment of the present application, each group into which the plurality of first drive lines and the plurality of second drive lines are divided may comprise the first type of drive lines (the group composed by 20 1 , 20 2 , 20 3 30 1 , 30 2 , 30 3 ) and the second type of drive lines (the group composed by 20 n−2 , 20 n−1 , 20 n , 30 n−2 , 30 n−1 , 30 n ). As can be seen from FIGS. 6A and 6B , adopting such grouped wiring manner, the grouping manner of the plurality of first drive lines and the plurality of second drive lines is more flexible, the drive lines can be selected to compose the group as needed by design and display requirements, without being restricted by the type of the drive lines per se.

In contrast, as shown in FIG. 7B , in the display device 7 B according to the sixth embodiment of the present application, each group into which the plurality of first drive lines and the plurality of second drive lines are divided may comprise drive lines that are not adjacent (e.g., the group composed by 20 1 , 20 3 , 20 5 : 20 n−4 , 20 n−2 , 20 n : 30 1 , 30 3 , 30 5 ; and 30 n−4 , 30 n−2 , 30 n that are not adjacent).

The display component 100 is configured to output initial light corresponding to the second image to be displayed by the second display device 902 (light indicated by the solid-line arrow shown in FIG. 13 ). The light path converting component 200 is configured to receive the initial light corresponding to the second image from the display component 100 , and perform light path conversion on the initial light corresponding to the second image to thereby form a virtual image corresponding to the second image, wherein the virtual image corresponding to the second image can be perceived by a viewer at a particular position, and a size of the virtual image perceived is greater than a display size of the display component 100 .

In an embodiment of the present application, the first angle is 90 degrees. In this case, a first size La of the display component in a direction vertical to the first plane is made smaller than a second size Lb of the display component in a direction parallel to the first plane. Thus, when the second display device 902 is provided within a wearable electronic apparatus, for example, when the electronic apparatus is smart glasses, the display component 100 is provided within a frame at one side (i.e., glass leg) of the smart glasses, it is such configured so that thickness of the frame within which the display component 100 is provided is thinner. Similarly, when the electronic apparatus is a smart watch, the display component 100 is provided within a wrist strap at one side of the smart watch, and it is such configured no that thickness of the wrist strap within which the display component 100 is provided is thinner. Accordingly, the display component 100 according to the second exemplary embodiment of the present application achieves a thickness reduction in a specific direction, and thereby achieves a thickness reduction in a specific direction of the second display device 902 .
FIGS. 15A and 15B are structural block diagrams illustrating a display device according to a twelfth embodiment of the present application. Similar to the display device according to the eleventh embodiment of the present application as shown in FIG. 14 , the second display device 902 according to the eleventh embodiment of the present application also comprises a display component 100 and a light path converting component 200 . As shown in FIG. 15A , the display component 100 A specifically comprises a light source subunit 111 , a light uniforming subunit 112 , and a display unit 12 , wherein the light uniforming subunit 112 sets the light source subunit 111 overlapped in an emission direction of the initial light corresponding to the second image, and uniforms a point light source emitted by the light source subunit 111 as backlight. Different than that, as shown in FIG. 15B , in the second display device 902 , the display component 100 B specifically comprises a light emitting unit 11 and a display unit 12 . The light emitting unit 1 is configured to generate and emit plane backlight (light indicated by the dotted-line arrow shown in FIG. 15B ), which is on the first plane as described with reference to FIG. 14 . The display unit 12 is provided within an irradiation area of the backlight, and configured to generate the initial light corresponding to the second image based on the second image (e.g. light indicated by the solid-line arrow shown in FIG. 15B ).
Therefore, in the second display device 902 according to the twelfth embodiment of the present application as shown in FIG. 15B , a combination manner of a single point light source and an optical light uniforming system as shown in FIG. 15A is replaced with a single light emitting unit 11 that emits plane backlight, so that thickness of the display component 10 in the second display device 902 according to the ninth exemplary embodiment of the present application is reduced in the emission direction of the initial light corresponding to the second image.

Therefore, the exit direction of the plane backlight converted by the light guide subunit 102 approximately can be considered as in the same direction (i.e., the second direction), which avoids the generation of stray light that exits towards a direction different than the second direction.
Therefore, in the light emitting unit 11 of the display device according to the thirteenth embodiment of the present application, the light emission direction of the light source subunit 101 is different than the light emission direction of the light converted by the light guide subunit 102 (i.e., in a direction vertical to the emission direction of the backlight, the light source subunit 101 is provided at a side of the light guide subunit 102 ), so that in comparison with the case of providing the light source subunit and the light guide subunit overlapped in the emission direction of the backlight, thickness of the display component 10 in the display device 3 according to the thirteenth embodiment of the present application is reduced in the emission direction of the initial light corresponding to the second image.

The display unit 52 is provided within an irradiation area of the backlight, and configured to generate the initial light corresponding to the second image based on the second image (light indicated by the solid-line arrow shown in FIG. 17 ). Further, the initial light corresponding to the second image from the display unit 52 (after being modulated as S-polarized light) is reflected at the PBS which serves as the beam splitting unit 53 , to be guided to the light path converting component via the beam splitting unit 53 .
FIG. 18 is a structural block diagram illustrating a display component in a display device according to a fifteenth embodiment of the present application. As shown in FIG. 18 , the display component 100 in the display device according to the fifteenth exemplary embodiment of the present application comprises a light emitting unit 61 , a display unit 62 , and a beam splitting unit 63 . Specifically, the display unit 62 is configured to generate a display signal corresponding to the second image based on the second image. The light emitting unit 61 is configured to generate the initial light corresponding to the second image based on the display signal. That is, the light emitting unit 61 and the display unit 62 in the display device according to the fifteenth embodiment of the present application may be implemented as a self-luminous type OLED display device, the display unit 62 is a control unit that generates a display drive signal based on the fifteenth image to be displayed, the light emitting unit 61 is a self-luminous layer that executes emitting display based on the received display drive signal.

In an embodiment of the present application, the beam splitting unit 63 is a polarization beam splitter (PBS).
Therefore, in the display component 100 of the display device according to the fifteenth embodiment of the present application, the display unit and the light emitting unit are integrally provided on one side of the beam splitting unit, so that a size of the display device in the direction of generating the initial light is smaller than a size of display device in the direction of generating the initial light in the case where the display unit and the light emitting unit are integrally provided on both sides of the beam splitting unit (the case shown with reference to FIG. 17 ).
FIG. 19 is a structural block diagram illustrating a display unit in a display device according to a sixteenth embodiment of the present application. The display unit 12 shown in FIG. 19 may be applied to the display component described with reference to FIGS. 15 to 18 . As shown in FIG. 19 , the display unit 12 comprises a micro-display subunit 701 , a circuit board subunit 702 , and a substrate subunit 703 . Specifically, the micro-display subunit 701 is configured with an array of a plurality of pixel cells, each pixel cell being used for generating the initial light corresponding to the second image. The circuit board subunit 702 is configured to provide a control signal based on the second image to control the pixel cells in the micro-display subunit 701 to generate the initial light corresponding to the second image. The substrate subunit 703 is configured to arrange the micro-display subunit 701 and the circuit board subunit 702 thereon. Flexural strength and fracture toughness of the substrate subunit 703 may be denoted by the following equations:
σ f = 2 ⁢ E ⁢ ⁢ Υ f C ( Equation ⁢ ⁢ 1 ) K ZC = 2 ⁢ ⁢ Z ⁢ ⁢ Υ f ( Equation ⁢ ⁢ 2 )
where σ f is flexural strength, K ZC is fracture toughness, E is elastic modulus, γ f is fracture energy, and C is crack size. As can be seen from the above Equations 1 and 2, in order to improve strength of the material, fracture energy and elastic modulus must be increased, to reduce fracture size. To achieve toughness of the material, fracture energy and elastic modulus must be increased. It is known that the substrate subunit is typically made from metal material like aluminum, which always reaches a thickness of 1.6 mm. Elastic modulus of the non-metallic material, like ceramic material, is much larger than that of the metals, often higher by one to several times.

Thus, in the display unit of the display device according to the sixteenth embodiment of the present application, the substrate subunit 703 is made from non-metallic material that meets a predetermined intension, so that thickness of the substrate subunit is lower than that of the substrate subunit 703 made from metallic material that meets a predetermined intension (e.g., as low as 0.25 mm).

Alternatively, the display component 100 comprises a light emitting unit 11 , a display unit 12 , and a beam splitting unit 13 (as shown in FIG. 20B ), this type of display component has already been described above with reference to FIG. 17 . Here, repeated descriptions of the display component 100 and its light path will be omitted.
As shown in FIGS. 20A and 20B , the light path converting component unit 200 further comprises a collimating unit 21 and a waveguide unit 22 , the collimating unit 21 is configured to collimate the initial light corresponding to the second image from the display component 10 into collimated light corresponding to the second image, and lead the same into the waveguide unit. Specifically, the collimating unit 21 comprises a first collimating subunit 201 and a second collimating subunit 202 provided opposite to each other, and a polarization beam splitting subunit 203 provided between the first collimating subunit 201 and the second collimating subunit 202 , the initial light corresponding to the second image from the display component 100 is reflected by the polarization beam splitting subunit 203 to the first collimating subunit 201 , thereafter it is collimated by the first collimating subunit 201 and the second collimating subunit 202 , and exited by the polarization beam splitting unit 203 as the collimated light corresponding to the second image. The waveguide unit 22 guides the collimated light from the collimating unit 21 to the particular position, wherein the collimated light corresponding to the second image is for forming the virtual image corresponding to the second image. In an embodiment of the present application, the first collimating subunit 201 and the second collimating subunit 202 may be a single lens or a lens group as needed by design. It is possible to implement adjustment of a size of the virtual image corresponding to the second image by adjusting the relative position of the lens or lens group by which the first collimating subunit 201 and the second collimating subunit 202 are configured.
In addition, as shown in FIGS. 20A and 20B , the waveguide unit 22 further comprises a first reflection subunit 204 and/or a second reflection subunit 205 , it is possible to control to guide the collimated light from the collimating unit 21 and corresponding to the second image to the particular position to exit, by setting the position and angle of the first reflection subunit 204 and/or the second reflection subunit 205 . In a first case, the collimating unit 21 and the display component 10 are located at a first side relative to the plane on which the waveguide unit 22 is located, when the first reflection subunit 204 as shown in FIGS. 20A and 20B is provided, it is possible to exit towards the first side. In a second case, when the second reflection subunit 205 as shown in FIGS. 20A and 20B is provided, the collimated light corresponding to the second image may exit towards a second side relative to the plane on which the waveguide unit 22 is located, the first side and the second side are opposite sides relative to the plane on which the waveguide unit is located. Specifically, when the display device is applied to for example a head-mounted electronic apparatus, it is possible to adopt the configuration example in the first case, the collimated light corresponding to the second image is made to exit towards the first side, that is, the collimated light is made to exit towards the eyes of a user wearing the head-mounted electronic apparatus. When the display device is applied to for example a wrist-mounted electronic apparatus, it is possible to adopt the configuration example in the second case, the collimated light corresponding to the second image is made to exit towards the second side, that is, the collimated light is made to exit towards the eyes of a user wearing and viewing the wrist-mounted electronic apparatus. In addition, it will be further explained below in detail that the exit direction of the display device can be set as required by viewing, for example, rotation of the first reflection subunit 204 and/or the second reflection subunit 205 may be controlled to control the exit direction of the first reflection subunit 204 and/or the second reflection subunit 205 , thus achieving a switch of bi-directional display of the display device.
Therefore, in the display device according to the seventeenth embodiment of the present application, in the collimating unit 21 , a folded imaging light path between the first collimating subunit 201 and the second collimating subunit 202 is implemented by using the polarization beam splitter 203 , thereby an overall size of the display device is reduced.
