Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronics, and in particular to a display device and an electronic device. BACKGROUND

[0002] Currently, a VR optical scheme mainly includes a lens or lens group (Lens / Lens group) and a display screen, the display screen including a display area and a frame glue / black border area, wherein the Lens / Lens group usually includes an aspherical mirror, a Fresnel lens or a Pancake folded light path, and a driving circuit of the display screen is designed in the frame glue / black border area of the display screen, so that almost all VR display screens will have a certain black border, including a Fast LCD and an OLED os. Light emitted by the display screen is received by the human eye through the lens, light emitted by the center position of the display screen is received by the human eye at a normal viewing angle through the lens, and light emitted by the edge of the display screen is received by the human eye at a large viewing angle through the lens. Therefore, the human eye can see pictures at various angles, and the feeling is an image magnified by the lens.

[0003] In the related art, the size of the display screen of the VR device is relatively small due to the limitation of the single exposure size of the exposure machine, so that the eye-in view angle of the VR device is relatively small, such as about 90° or 105°. The monocular field of view of the human eye exceeds 120°, so that a significant black border can be seen at the periphery of the display screen with a small viewing angle. SUMMARY

[0004] The embodiments of the present application provide a display device and an electronic device, which can reduce the black border of the display device.

[0005] The embodiments of the present application provide a display device, which includes:

[0006] a display screen including a display area and a non-display area;

[0007] an optical layer disposed on a light-emitting surface side of the display screen, the optical layer including a first area corresponding to the display area and a second area corresponding to the non-display area away from a top of the display screen; and

[0008] a reflective layer disposed between the optical layer and the display screen and corresponding to the non-display area;

[0009] wherein the first area is provided with a first reflective structure, the second area is provided with a second reflective structure, the first reflective structure reflects part of the light emitted by the display screen to the reflective layer, the reflective layer reflects the light reflected by the first reflective structure to the second reflective structure, and the second reflective structure reflects the light reflected by the reflective layer to the outside of the display device.

[0010] This application also provides an electronic device, which includes:

[0011] shell; and

[0012] A display device is installed in the housing, and the display device is the one described above.

[0013] In this embodiment, the display device includes a display screen, a reflective layer, and an optical layer arranged sequentially. The top of the optical layer away from the display screen includes a first area corresponding to the display area and a second area corresponding to the non-display area. The first area is provided with a first reflective structure, and the second area is provided with a second reflective structure. The first reflective structure can reflect part of the light emitted from the display screen to the reflective layer. The reflective layer reflects the light reflected by the first reflective structure to the second reflective structure. The second reflective structure reflects the light reflected by the reflective layer to the outside of the display device, so that part of the light emitted from the display area can be emitted from above the non-display area, which can reduce the black border of the display device, increase the viewing angle, and improve the display effect of the display device.

[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative effort belong to the protection scope of the present application.

[0033] The embodiments of the present application provide a display device, please refer to Figure 1 and Figure 2 , Figure 1 A schematic structural diagram of the display device provided by the embodiments of the present application,Figure 2 for Figure 1 The diagram shows a cross-sectional view of the display device along the KK direction. The display device 10 includes a display screen 120, a reflective layer 140, and an optical layer 160. The display screen 120 may include a display area 121 and a non-display area 123. The display area 121 can emit light for display, allowing the user to receive the light and see the corresponding image. For example, a display unit 128 located in the display area 121 emits light. The non-display area 123 may surround the display area 121. The non-display area 123 may contain driving circuitry for the display area 121, peripheral wiring, and structures protecting the display area 121.

[0034] The optical layer 160 is disposed on the light-emitting surface side of the display screen 120. The optical layer 160, away from the top of the display screen 120, includes a first region 161 corresponding to the display area 121 and a second region 163 corresponding to the non-display area 123.

[0035] A reflective layer 140 is disposed between the optical layer 160 and the display screen 120, and is disposed corresponding to the non-display area 123. The reflective layer 140 is capable of reflecting light that shines on it, and the reflective layer 140 has a high reflectivity, such as exceeding 85%, 90%, or 95%.

[0036] Please combine Figure 3 , Figure 3 for Figure 2 The diagram shows the structure of the reflective layer and optical layer in the display device. A first reflective structure 162 is provided in the first region 161, and a second reflective structure 164 is provided in the second region 163. The first reflective structure 162 reflects a portion of the light S10 emitted from the display screen 120 to the reflective layer 140. The reflective layer 140 reflects the light S12 reflected by the first reflective structure 162 to the second reflective structure 164. The second reflective structure 164 reflects the light S14 reflected by the reflective layer 140 to the outside of the display device 10, i.e., the light S16 in the diagram. This allows a portion of the light S10 emitted from the display area 121 to exit from above the non-display area 123, as shown. Figure 4 As shown, this can reduce the black border of the display device 10, increase the viewing angle, and improve the display effect of the display device 10.

[0037] It should be noted that the first area 161 can also emit part of the light emitted by the display screen 120, that is, among the light emitted by the display screen 120 corresponding to the first area 161, part of the light S20 can be emitted from the first area 161 to the outside of the display device 10, and part of the light S10 is reflected by the first reflecting structure 162, the reflecting layer 140 and the second reflecting structure 164 in turn, and then emitted from above the second area 163, that is, the non-display area 123 to the outside of the display device 10. The light emitted from the first area 161, such as S20, can allow the user to normally see the image at the edge of the display area 121, and the light emitted from the second area 163, such as S16, can be seen by the user, so that the user can see more image information, so as to shield the non-display area 123. It can also be understood that the final display range of the display device 10 not only includes the range corresponding to the display area 121, but also includes the range corresponding to at least part of the non-display area 123, so as to reduce the black edge of the display device 10, increase the visual angle into the eye, and improve the display effect of the display device 10.

[0038] It can be understood that the reflecting layer 140 and the optical layer 160 can be two independent components. The reflecting layer 140 can be arranged on the display screen 120 first, and then the optical layer 160 is arranged on the reflecting layer 140. In some examples, the optical layer 160 is provided with a notch corresponding to the reflecting layer 140, and the reflecting layer 140 is filled in the notch, so that the optical layer 160 and the reflecting layer 140 are flush on the side facing the display screen. In another example, the optical layer 160 can also not be provided with a notch, and the side of the optical layer 160 facing the display screen 120 is a flat structure, and the part of the optical layer 160 exceeding the reflecting layer 140 is filled with optical glue between the display screen 120. In another example, the optical layer 160 can be etched to form a notch, and then the reflecting layer 140 is formed in the notch, and the optical layer 160 and the reflecting layer 140 are flush on the side facing the display screen 120, and then the optical layer 160 and the reflecting layer 140 are arranged on the display screen 120.

[0039] Please refer to Figure 5 and Figure 6 , Figure 5 for Figure 3 the enlarged schematic structure diagram of the A part of the optical layer shown in the schematic structure diagram, Figure 6 for Figure 3An enlarged schematic view of the B part of the optical layer is shown. The first reflective structure 162 includes a plurality of first microstructures 1622 arranged at intervals, and the second reflective structure 164 includes a plurality of second microstructures 1642 arranged at intervals. The plurality of first microstructures 1622 are located in the normal projection of the display area 121 of the display screen 120, and the plurality of second microstructures 1642 are located in the normal projection of the non-display area 123 of the display screen 120. The area between the plurality of first microstructures 1622 can allow the light emitted by the display area 121 to normally pass through, each first microstructure 1622 can reflect part of the light signal emitted by the display area 121, and each second microstructure 1642 can also reflect part of the light signal to change its transmission path, so that it is emitted out of the display device 10, and the emission angle is smaller, that is, the angle with the normal line perpendicular to the display screen 120 is smaller, and it is easier to enter the user's eyes.

[0040] Exemplarily, the first microstructure 1622 is provided with a first arc surface 1623 on the side facing the display screen 120, and the first arc surface 1623 is curved towards the display screen 120; the second microstructure 1642 is provided with a second arc surface 1643 on the side away from the display screen 120, and the second arc surface 1643 is curved away from the display screen 120. Part of the light emitted by the display area 121 is irradiated to the first arc surface 1623, the first arc surface 1623 reflects it, and the reflected light is reflected to the reflective layer 140, the reflective layer 140 continues to reflect the light, and the reflected light is reflected to the second arc surface 1643, the second arc surface 1643 changes the propagation route and angle of the light, and the light is emitted out of the display device 10 from the second area 163.

[0041] For example, the first area 161 of the optical layer 160 away from the display screen 120 can be provided with a plurality of first grooves, the bottom wall of the first groove is arc-shaped, then the first groove is filled with a reflective material to form the first microstructure 1622 with the first arc surface 1623. The first microstructure 1622 can be a hemisphere or a bowl, and the first microstructure 1622 includes a first arc surface 1623 and a first plane arranged opposite to each other, the first arc surface 1623 is located on the side of the first microstructure 1622 facing the display screen 120, and the first plane is located on the side of the first microstructure 1622 away from the display screen 120.

[0042] For example, the second region 163 on the side of the optical layer 160 away from the display screen 120 can also be provided with multiple second grooves. The bottom wall of the second groove can be flat, and the top surface of the second groove can be arc-shaped. Then, reflective material is filled in the second groove to form a second microstructure 1642 with a second arc surface 1643. The second microstructure 1642 can also be hemispherical or bowl-shaped. The second microstructure 1642 includes a second arc surface 1643 and a second flat surface arranged opposite to each other. The second arc surface 1643 is located on the side of the second microstructure 1642 away from the display screen 120, and the second flat surface is located on the side of the second microstructure 1642 facing the display screen 120.

[0043] In another example, please combine Figure 7 , Figure 8 and Figure 9 , Figure 7 for Figure 2 The diagram shows a second structural representation of the reflective and optical layers in the displayed device. Figure 8 for Figure 7 A magnified schematic diagram of part C in the optical layer shown. Figure 9 for Figure 7 The diagram shows an enlarged view of part D in the optical layer. The first microstructure 1622 has a first inclined surface 1625 on the side facing the display screen 120. The first inclined surface 1625 is inclined from the first region 161 towards the second region 163 and away from the display screen 120. The second microstructure 1642 has a second inclined surface 1645 on the side away from the display screen 120. The second inclined surface 1645 is inclined from the second region 163 towards the first region 161 and closer to the display screen 120.

[0044] For example, a plurality of third grooves can be provided in the first region 161 of the optical layer 160 on the side away from the display screen 120. The sidewall of the third groove facing the second region 163 is inclined and extends from the first region 161 to the second region 163, tilting away from the display screen 120. Then, reflective material is filled in the third groove to form a first microstructure 1622 with a first inclined surface 1625. The first microstructure 1622 can be a triangular structure. The side of the first microstructure 1622 away from the display screen 120 is parallel to the display surface of the display screen 120, and the side of the first microstructure 1622 away from the second region 163 is perpendicular to the display surface of the display screen 120. The side of the first microstructure 1622 facing the second region 163 is inclined, i.e., the first inclined surface 1625.

[0045] For example, the second region 163 of the optical layer 160 far from the side of the display screen 120 can be provided with a plurality of fourth grooves, the sidewall of the fourth grooves toward the first region 161 is a slope, and the fourth grooves extend from the second region 163 to the first region 161 and are inclined toward the display screen 120, then the fourth grooves are filled with a reflective material to form a second microstructure 1642 with a second slope 1645. The second microstructure 1642 can also be a triangular structure, the side of the second microstructure 1642 far from the display screen 120 is parallel to the display surface of the display screen 120, the side of the second microstructure 1642 far from the first region 161 is perpendicular to the display surface of the display screen 120, and the side of the second microstructure 1642 toward the first region 161 is a slope, i.e., the second slope 1645.

[0046] Please continue to refer to Figure 5 and Figure 8 In this way, among the light emitted by the display region 121 corresponding to the first reflective structure 162, most of the light can be emitted to the outside from the interval space between the plurality of first microstructures 1622, and the influence on the display region 121 is relatively small. Of course, in other embodiments, the distance L1 between the adjacent two first microstructures 1622 along the arrangement direction of the plurality of first microstructures 1622 can also be set as needed, for example, the distance L1 between the adjacent two first microstructures 1622 is equal to or less than the width of the first microstructure 1622.

[0047] Optionally, please refer to Figure 10 , Figure 10 for Figure 2 A third structure diagram of the reflective layer and the optical layer in the display device. The distribution density of the plurality of first microstructures 1622 is inversely related to the distance from the second region 163. The farther the plurality of first microstructures 1622 are from the second region 163, the smaller the distribution density is, i.e., the closer to the center of the display region 121, the smaller the distribution density of the plurality of first microstructures 1622 is, and the smaller the influence on the display region 121 is, and the closer to the display center, the smaller the influence is, and the smallest influence on the display effect, at the same time, the closer the plurality of first microstructures 1622 are to the second region 163, the larger the distribution density is, i.e., the closer to the non-display region 123, the larger the distribution density of the plurality of first microstructures 1622 is. Because the edge of the display region 121 is relatively less sensitive to the user and the importance of the image content is also relatively low compared to the center of the display region 121, the plurality of first microstructures 1622 with a larger distribution density can reflect more light to the reflective layer 140, so that the light corresponding to the second reflective structure 164, i.e., the non-display region 123, and the light corresponding to the first reflective structure 162 are closer, so that the edge transition of the image finally displayed by the display device 10 is smoother.

[0048] Optionally, the distribution density of the plurality of second microstructures 1642 is inversely related to the distance from the first region 161. The closer the plurality of second microstructures 1642 is to the first region 161, the greater the distribution density, i.e. the closer to the display region 121, the greater the distribution density of the plurality of second microstructures 1642, the more light of the display device 10 can be reflected, and the closer to the light emitted by the adjacent display region 121, so that the edge transition of the image ultimately presented by the display device 10 is smoother. Considering that the farther the non-display region 123 is from the display region 121, the less sensitive it is to the user, therefore the farther the plurality of second microstructures 1642 is from the first region 161, the smaller the distribution density, i.e. the farther from the display region 121, the smaller the distribution density of the plurality of second microstructures 1642, the less light of the display device 10 can be reflected, and the more black edges can be reduced.

[0049] It should be noted that in some embodiments, the distribution density of the plurality of first microstructures 1622 is inversely related to the distance from the second region 163, and the distribution density of the plurality of second microstructures 1642 is inversely related to the distance from the first region 161. The distribution density of the plurality of first microstructures 1622 can also be inversely related to the distance from the second region 163, and the plurality of second microstructures 1642 can be uniformly distributed. The distribution density of the plurality of second microstructures 1642 can also be inversely related to the distance from the first region 161, and the plurality of first microstructures 1622 can be uniformly distributed. Of course, in other embodiments, the distribution density of the plurality of first microstructures 1622 and the plurality of second microstructures 1642 can also be set as needed, for example, the distribution density of the plurality of first microstructures 1622 is the same, i.e. the plurality of first microstructures 1622 is uniformly arranged, and the distribution density of the plurality of second microstructures 1642 is the same, i.e. the plurality of second microstructures 1642 is uniformly arranged. For another example, the distribution density of the plurality of first microstructures 1622 is positively related to the distance from the second region 163, and the distribution density of the plurality of second microstructures 1642 is positively related to the distance from the first region 161.

[0050] Optionally, please refer to Figure 11 and Figure 12 , Figure 11 for Figure 2 a fourth structure diagram of the reflective layer and the optical layer in the display device, Figure 12 for Figure 2A fifth structure of the reflective layer and the optical layer in the display device is shown in the schematic view. The second region 163 can be provided with a plurality of third microstructures 1624 near one end of the first region 161, the plurality of third microstructures 1624 being located between the first microstructure 1622 and the second microstructure 1642, and the third microstructure 1624 having the same structure as the first microstructure 1622. The third microstructure 1624 is located in the orthographic projection of the display screen 120 in the non-display region 123 and near the display region 121, so as to allow more light to enter the second reflective structure 164 and enable the light to penetrate deeper into the second region 163, i.e., to the portion of the second region 163 farther away from the display region 121, thereby reducing the black border.

[0051] For example, the distribution density of the plurality of third microstructures 1624 can be inversely related to the distance from the second microstructure 1642, i.e., the closer the distance from the second microstructure 1642, the higher the distribution density. The distribution density of the plurality of third microstructures 1624 can also be greater than the distribution density of the plurality of first microstructures 1622. In another example, the plurality of third microstructures 1624 can also be uniformly distributed. In this case, the distribution density of the plurality of third microstructures 1624 can be greater than or the same as the distribution density of the plurality of first microstructures 1622.

[0052] Of course, in some other embodiments, the second region 163 can not be provided with the third microstructure, but only with the second microstructure 1642.

[0053] Optionally, please continue to refer to Figure 1 The optical layer 160 can be provided only in the peripheral region of the display screen 120. For example, the optical layer 160 can be frame-shaped and cover the peripheral region of the display screen 120. In this case, the length of the first region 161 can be less than the length of the second region 163 along the length direction or the width direction of the display screen 120. The length of the first region 161 is relatively small, and thus has less impact on the display region 121. Of course, in some other embodiments, the length of the first region 161 can be greater than or equal to the length of the second region 163 along the length direction or the width direction of the display screen 120.

[0054] In this case, the size of the optical layer 160 and the reflective layer 140 can be set as needed. For example, the optical layer 160 and the reflective layer 140 can extend to the edge of the display screen 120, which can also be understood as the optical layer 160 and the reflective layer 140 being flush with the edge of the display screen 120, so as to minimize the black border of the display screen 120. In another example, of course, the optical layer 160 and the reflective layer 140 can extend to the middle portion of the non-display region 123 of the display screen 120.

[0055] Please refer to Figure 13 and Figure 14 ,Figure 13 FIG. 8 shows another structure of the display device provided in the embodiments of the present application, Figure 14 Figure 13 FIG. 8 shows another structure of the display device provided in the embodiments of the present application,The optical layer 160 can cover the entire display screen 120. The optical layer 160 can be conveniently disposed on the display screen 120 and cover the entire display screen 120. The optical layer 160 can be an optical film piece stacked above the display screen 120. The intermediate sub-region 1611 corresponds to the middle part of the display region 121, and the side sub-region 1613 corresponds to the side part of the display region 121. The first reflective structure 162 is disposed in the side sub-region 1613, i.e., the optical layer 160 is provided with the first reflective structure 162 only in the side part of the display region 121.

[0056] The optical layer 160 can also be formed by coating an optical material on the display screen 120, then curing to form a substrate, and then processing the cured substrate to form the first microstructure 1622 and the second microstructure 1642. For example, grooves corresponding to the first microstructure 1622 and the second microstructure 1642 are etched on the substrate, and then a reflective material is filled in the grooves to form the first microstructure 1622 and the second microstructure 1642.

[0057] It should be noted that the first reflective structure, the second reflective structure, etc. of the optical layer in the embodiments can adopt the structure in any one of the above embodiments, and the reflective layer in the embodiments can adopt the structure in any one of the above embodiments, which will not be described here.

[0058] It can be understood that the display screen 120 can include a substrate 122, a display unit 128, a protective cover plate 126, etc. The display unit 128 is disposed in the middle region of the substrate 122, and the region provided with the display unit 128 is the display region 121. The peripheral region of the substrate 122 is provided with a driving circuit (not shown in the figure) for driving the display unit 128, peripheral wiring, etc., and the corresponding region is the non-display region 123. The display screen is further provided with a frame glue 124, etc. in the peripheral region of the substrate, and the protective cover plate 126 is disposed above the display unit 128, the driving circuit, and the frame glue 124. The protective cover plate 126 can be transparent glass or plastic, etc. The display unit 128 can be an OLED display unit, i.e., the display screen 120 is an OLED display screen. The display screen can also be of other structures, for example, the display screen can be a liquid crystal display screen, and the embodiments do not limit the structure of the display screen.

[0059] This application also provides an electronic device, which includes a housing and a display device. The display device is mounted on the housing. The display device can be any of the display devices in the above embodiments, and will not be described again here.

[0060] The following explanation uses an electronic device as an example of a virtual reality (VR) device. Please refer to [link / reference]. Figure 15 , Figure 15 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application. The electronic device 100 includes a display device 10 and a lens group 20. The human eye can see the light emitted by the display device 10 through the lens group 20, thereby obtaining the corresponding image.

[0061] It should be noted that, please refer to Figure 4 and Figure 16 The issue of black borders on displays is particularly severe in VR devices using OLED OS. This is due to a limitation: current mainstream OLED OS sizes range from 1.3 to 1.45 inches. The inability to increase this size is primarily due to the limitations of the single exposure size of the exposure machine. This relatively small display size restricts the design of the entire optical engine. The most obvious problem is the limited viewing angle. Many current VR devices have a viewing angle of around 105° using a 2.1-inch display. If a 1.3-inch OLED OS display is used, the viewing angle is only around 90°. The human eye's monocular field of view exceeds 120°, therefore, noticeable black borders are seen around the edges of displays with smaller viewing angles; that is, anything beyond a certain viewing angle (such as 90°) is shrouded in black.

[0062] Compared to display devices in related technologies, the display device of this embodiment can improve the image with smaller black borders. The light emitted from the display screen is reflected by the lens assembly before reaching the human eye, where the lens assembly also acts as an eyepiece for magnification. On the outer side of the display area of ​​the display device, at least a portion of the black border has an optical layer and a reflective layer. This black border area can also emit light, such as light corresponding to the optical layer 160. This light can be seen by the human eye through the lens assembly, allowing the human eye to see a wider viewing angle. It is understood that this light can be used only as supplementary lighting, without displaying a specific image, such as forming a luminous halo, giving the image of the display device a bright halo around its perimeter, replacing the black border. When the display area of ​​the display device is limited, this helps to increase the display area, allowing for some illumination at a wide viewing angle of the VR device, preventing the field of view from being obscured by black. Figure 4As shown, the scene viewed by the human eye is obviously enlarged, the field of view is enlarged, and the black shielding area is reduced. The edge position of the expanded image is not a single pixel clear display, but a similar outward smearing phenomenon, but since the restoration ability of the edge of the VR device is relatively poor, the smearing of this display screen will not have a great impact on the final optical machine into the eye picture. Moreover, since the human eye is not sensitive to the display picture of the super large viewing angle, only sensitive to brightness and motion, therefore, the specific picture at this position does not matter.

[0063] It can be understood that the electronic device in the embodiment of the application can also be a mobile terminal such as a mobile phone and a tablet computer, and can also be a game device, an augmented reality (AR) device, a video playing device, a wearable device and the like having a battery. The wearable device can be a wireless earphone, smart glasses, a smart helmet, a smart bracelet, a smart watch and the like.
