Description

Technical Field

[0001] This invention relates to the field of display technology, and more particularly to a display panel and a display device. Background Technology

[0002] With the rapid development of display technology, display devices with facial recognition capabilities have become widespread in people's lives. To improve screen-to-body ratio, under-display optical component solutions have emerged. These solutions place the optical components below the display area, thus eliminating the need for space in the bezel area to house the optical components and reducing the size of the bezel. However, the facial recognition performance of current display devices still needs improvement. Summary of the Invention

[0003] In view of this, the present invention provides a display panel and a display device to improve the facial recognition effect of the display panel and the display device and ensure the accuracy of the facial recognition results.

[0004] In a first aspect, embodiments of the present invention provide a display panel including a plurality of organic light-emitting units, a plurality of pinhole imaging structures and a photosensitive unit, wherein the pinhole imaging structures are located between adjacent organic light-emitting units in a first direction, and the first direction is parallel to the light-emitting surface of the display panel;

[0005] The pinhole imaging structure includes a focusing unit and an imaging pinhole. In a second direction, the imaging pinhole is located between the focusing unit and the photosensitive unit, and the focal point of the focusing unit is located in the imaging pinhole. The second direction is the light emission direction of the organic light-emitting unit.

[0006] Secondly, embodiments of the present invention also provide a display device, including the display panel described in the first aspect of the present invention.

[0007] In this embodiment of the invention, the display panel includes multiple organic light-emitting units, multiple pinhole imaging structures, and a photosensitive unit. In a first direction, the pinhole imaging structures are located between adjacent organic light-emitting units. Each pinhole imaging structure includes a focusing unit and an imaging aperture. In a second direction, the imaging aperture is located between the focusing unit and the photosensitive unit, and the focal point of the focusing unit is located within the imaging aperture. Using this scheme, the recognition light reflected from an external object first passes through the focusing unit in the pinhole imaging structure. The focusing unit converges the recognition light, focusing it into the imaging aperture. This results in the recognition light forming a larger image area after passing through the imaging aperture, increasing the amount of light entering the imaging aperture area. This allows the photosensitive unit to collect more recognition light carrying facial information, ensuring the photosensitive unit's ability to collect imaging information and improving the facial recognition accuracy of the display panel.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0021] Figure 1 This is a schematic diagram of the structure of a display panel in the prior art. Figure 2 for Figure 1 A schematic diagram of the cross-sectional structure along the A-A' direction, as shown below. Figure 1 As shown, Figure 1 In the middle, A1 is the normal display area, and A2 is the under-screen light sensing area. The existing design sets a black matrix 0' on the light-emitting side of the display panel to block external light from entering the display panel, thereby reducing the reflection of ambient light. Figure 2 Solid arrows represent the display light emitted by the organic light-emitting element 1' within the display panel, while dashed arrows represent the light reflected back from the object to be identified, B, such as the user's face. The light reflected back from the object to be identified, B, is imaged on the photosensitive element 3' through the light-transmitting hole 5', and the photosensitive element 3' identifies the object to be identified, B, based on the image information. The inventors discovered that, in Figure 1 and Figure 2 In the existing configuration shown, the amount of light entering through the light-transmitting hole 5' in the display panel is greatly reduced, and the photosensitive element 3' has a poor effect on collecting imaging information, which affects the facial recognition accuracy of the display device.

[0022] To address the shortcomings of the prior art, the present invention provides a display panel comprising a plurality of organic light-emitting units, a plurality of pinhole imaging structures, and a photosensitive unit, wherein the pinhole imaging structures are located between adjacent organic light-emitting units in a first direction, and the first direction is parallel to the light-emitting surface of the display panel;

[0023] The pinhole imaging structure includes a focusing unit and an imaging pinhole. In a second direction, the imaging pinhole is located between the focusing unit and the photosensitive unit, and the focal point of the focusing unit is located in the imaging pinhole. The second direction is the light emission direction of the organic light-emitting unit.

[0024] Through the above technical solution, the recognition light reflected back from the external object first passes through the focusing unit in the pinhole imaging structure. The focusing unit converges the recognition light, focusing it into the imaging pinhole. This allows the recognition light to form a larger image after passing through the imaging pinhole, increasing the amount of light entering the imaging pinhole area. This enables the photosensitive unit to collect more recognition light carrying facial information, ensuring the photosensitive unit's ability to collect imaging information and improving the facial recognition accuracy of the display panel.

[0025] The above is the core idea of ​​this invention. The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0026] Figure 3 This is a cross-sectional structural diagram of a display panel provided in an embodiment of the present invention, as shown below. Figure 3As shown, the display panel includes multiple organic light-emitting units 1, multiple pinhole imaging structures 2, and photosensitive units 3. In the first direction X, the pinhole imaging structures 2 are located between adjacent organic light-emitting units 1, wherein the first direction X is parallel to the light-emitting surface of the display panel; the pinhole imaging structure 2 includes a focusing unit 4 and an imaging pinhole 5. In the second direction Y, the imaging pinhole 5 is located between the focusing unit 4 and the photosensitive units 3, and the focal point 41 of the focusing unit 4 is located in the imaging pinhole 5; wherein the second direction Y is the light-emitting direction of the organic light-emitting unit 1.

[0027] refer to Figure 3 In this invention, the display panel includes multiple organic light-emitting units 1 for emitting display light; multiple pinhole imaging structures 2 and photosensitive units 3 are arranged in a first direction X, parallel to the light-emitting surface of the display panel. Each pinhole imaging structure 2 is located between adjacent organic light-emitting units 1, meaning that the pinhole imaging structures 2 and the organic light-emitting units 1 are alternately arranged in their vertical projections onto the light-emitting surface of the display panel. The recognition light 6 enters the display panel from the outside through the pinhole imaging structure 2. By positioning the pinhole imaging structure 2 between adjacent organic light-emitting units 1, it is ensured that the recognition light 6 transmitted within the pinhole imaging structure 2 does not interfere with the display light 7 emitted from the organic light-emitting units 1, thus guaranteeing both display and facial recognition effects.

[0028] The pinhole imaging structure 2 includes a focusing unit 4 and an imaging pinhole 5. Along the light emission direction of the organic light-emitting unit 1, the imaging pinhole 5 is located between the focusing unit 4 and the photosensitive unit 3; that is, the focusing unit 4 is close to the light-emitting surface of the display panel, and the imaging pinhole 5 is close to the photosensitive unit 3. Furthermore, the focal point 41 of the focusing unit 4 is located in the imaging pinhole 5. The recognition light 6 is focused by the focusing unit 4 into the imaging pinhole 5, and then reaches the photosensitive unit 3 through the imaging pinhole 5. Compared to the prior art where a black matrix is ​​set on the light-emitting side, in this embodiment of the invention, the presence of the focusing unit 4 within the pinhole imaging structure 2 can concentrate the light, focusing the recognition light 6 onto the imaging pinhole 5, thereby increasing the amount of light entering the imaging pinhole 5 area, allowing the photosensitive unit 3 to receive more recognition light 6, and improving facial recognition accuracy.

[0029] The specific arrangement of the organic light-emitting unit 1 is not limited in this embodiment of the invention, and those skilled in the art can configure it according to actual needs. For example, each organic light-emitting unit 1 may include an anode (not shown in the figure), a light-emitting material (not shown in the figure), and a cathode (not shown in the figure). Each organic light-emitting unit 1 is separated by a pixel definition layer 8. Figure 3 Only one organic light-emitting unit 1 is shown as an example, but the actual display panel includes multiple organic light-emitting units 1.

[0030] Among them, the photosensitive unit 3 can be an infrared sensing unit, and there can be one or more photosensitive units 3. Figure 3 An exemplary embodiment shows a photosensitive unit 3. When only one photosensitive unit 3 is provided, the vertical projection of the photosensitive unit 3 on the light-emitting surface of the display panel should overlap with the vertical projection of at least one pinhole imaging structure 2 on the light-emitting surface of the display panel, so as to ensure that the photosensitive unit 3 can receive the recognition light 6 passing through the pinhole imaging structure 2.

[0031] In this embodiment of the invention, the display panel includes multiple organic light-emitting units, multiple pinhole imaging structures, and a photosensitive unit. In a first direction, the pinhole imaging structures are located between adjacent organic light-emitting units. Each pinhole imaging structure includes a focusing unit and an imaging aperture. In a second direction, the imaging aperture is located between the focusing unit and the photosensitive unit, and the focal point of the focusing unit is located within the imaging aperture. Using this scheme, the recognition light reflected from an external object first passes through the focusing unit in the pinhole imaging structure. The focusing unit converges the recognition light, focusing it into the imaging aperture. This results in the recognition light forming a larger image area after passing through the imaging aperture, increasing the amount of light entering the imaging aperture area. This allows the photosensitive unit to collect more recognition light carrying facial information, ensuring the photosensitive unit's ability to collect imaging information and improving the facial recognition accuracy of the display panel.

[0032] Optionally, the specific arrangement of the focusing unit 4 and the imaging aperture 5 within the pinhole imaging structure 2, such as the film layer in which they are located, is not limited in the embodiments of the present invention. They can be set according to actual needs, as long as the focal point 41 of the focusing unit 4 is located in the imaging aperture 5. Any specific implementation scheme that enables the focal point 41 of the focusing unit 4 to be located in the imaging aperture 5 is within the scope of the technical solution protected by the embodiments of the present invention.

[0033] For example, Figure 4 This is a cross-sectional structural diagram of another display panel provided in an embodiment of the present invention, with reference to... Figure 4 In one possible embodiment, the display panel may further include a pinhole array layer 9, which is located on the side of the organic light-emitting unit 1 away from the light emission in the second direction Y; the pinhole array layer 9 includes a plurality of imaging pinholes 5.

[0034] Specifically, such as Figure 4 As shown, a small aperture array layer 9 can also be provided in the display panel. In the second direction Y, the small aperture array layer 9 is located on the side of the organic light-emitting unit 1 away from the light emission. It can also be understood that the small aperture array layer 9 is set on the side of the organic light-emitting unit 1 closer to the photosensitive unit 3. The small aperture array layer 9 is provided with multiple imaging apertures 5. The advantage of this setting is that the recognition light 6 can be focused on the side of the organic light-emitting unit 1 away from the light emission, further ensuring that there is no mutual interference between the display light 7 and the recognition light 6. In addition, the position of the imaging aperture 5 closer to the photosensitive unit 3 is also beneficial for the photosensitive unit 3 to collect the recognition light 6.

[0035] Optional, Figure 5 A cross-sectional structural diagram of another display panel provided in an embodiment of the present invention is shown below. Figure 5 As shown, in another possible embodiment, the display panel may further include a thin-film transistor array layer 10 and a light-shielding layer 11, the light-shielding layer 11 being located on the side of the thin-film transistor array layer 10 away from the organic light-emitting unit 1; the light-shielding layer 11 is reused as a pinhole array layer 9, the light-shielding layer 11 including a plurality of imaging pinholes 5.

[0036] Specifically, such as Figure 5 As shown, the display panel also includes a thin-film transistor array layer 10, which is disposed on the side of the organic light-emitting unit 1 away from the light-emitting unit. The thin-film transistor array layer 10 includes multiple thin-film transistors (not shown in the figure), which provide driving signals to the organic light-emitting unit 1 to drive the organic light-emitting unit 1 to emit light.

[0037] The specific configuration of the thin-film transistor array layer 10 is not limited in this embodiment of the invention. Those skilled in the art can configure it according to actual needs, and it will not be described in detail here.

[0038] Furthermore, such as Figure 5 As shown, a light-shielding layer 11 is also provided on the side of the thin-film transistor array layer 10 away from the organic light-emitting unit 1, and the light-shielding layer 11 is close to the photosensitive unit 3. The presence of the light-shielding layer 11 can prevent external ambient light from shining on the thin-film transistor array layer 10, causing leakage current at the electrode connections of the thin-film transistors, affecting the normal operation of the thin-film transistors, thereby improving the electrical performance of the thin-film transistors. Furthermore, when a light source for emitting facial recognition light is provided in the display panel, the presence of the light-shielding layer 11 blocks the light emitted by the light source, preventing the light from the light source from being transmitted to the organic light-emitting unit 1 and affecting the display effect of the display panel.

[0039] The light-shielding layer 11 can be reused as a small aperture array layer 9. When the small aperture array layer 9 is formed using the light-shielding layer 11, the light-shielding layer 11 includes multiple imaging apertures 5. Reusing the light-shielding layer 11 as a small aperture array layer 9 eliminates the need to form a separate small aperture array layer 9, which simplifies the fabrication process of the small aperture array layer 9, thereby reducing the manufacturing difficulty of the display panel and improving the manufacturing efficiency of the display panel.

[0040] Optional, Figure 6 This is a cross-sectional structural diagram of another display panel provided in an embodiment of the present invention, as shown below. Figure 6 As shown, in one possible embodiment, the display panel may further include at least two transparent flexible substrate layers 12, with a light-shielding layer 11 located between two adjacent transparent flexible substrate layers 12.

[0041] Specifically, such as Figure 6 As shown, in this embodiment, at least two transparent flexible substrate layers 12 can also be disposed in the display panel. The light-shielding layer 11 is disposed between two adjacent transparent flexible substrate layers 12; that is, a transparent flexible substrate layer 12 is disposed on each side of the light-shielding layer 11 in the light-emitting direction of the display panel. The transparent flexible substrate layers 12 do not affect the transmission of the recognition light 6 and also enable the display panel to have a certain degree of flexibility. Figure 6 The image shows two transparent flexible substrate layers 12, but the actual arrangement is not limited to this.

[0042] Optional, Figure 7 A cross-sectional structural diagram of another display panel provided in an embodiment of the present invention is shown below. Figure 7 As shown, in one possible embodiment, the display panel may further include a color filter layer 13, which is located on the light-emitting side of the organic light-emitting unit 1. The color filter layer 13 includes a plurality of color resists 14. The focusing unit 4 includes a convex lens structure 15, and the vertical projection of the convex lens structure 15 on the light-emitting surface of the display panel does not overlap with the vertical projection of the color resists 14 on the light-emitting surface of the display panel.

[0043] Specifically, such as Figure 7 As shown, a color filter layer 13 may also be disposed within the display panel, located on the light-emitting side of the organic light-emitting unit 1. The color filter layer 13 includes multiple color resists 14, each corresponding to a different organic light-emitting unit 1. The color resists 14 comprise color resist materials of different colors, and the color of each color resist 14 is the same as the emission color of its corresponding organic light-emitting unit 1. The presence of the color resists 14 reduces reflected light from ambient light within the display panel, improving the display effect. It should be noted that the corresponding arrangement of the two components described here can be understood as the vertical projections of the two components onto the light-emitting surface of the display panel at least partially overlapping. Figure 7 An example is shown of a color resist 14, but an actual display panel includes multiple color resists 14.

[0044] The focusing unit 4 includes a convex lens structure 15. The vertical projection of the convex lens structure 15 onto the light-emitting surface of the display panel does not overlap with the vertical projection of the color resist 14 onto the light-emitting surface of the display panel. This ensures that the pinhole imaging structure 2 is located between adjacent organic light-emitting units 1, thus avoiding mutual interference between the display light 7 and the recognition light 6.

[0045] It is worth mentioning that the focusing unit 4 is set as a convex lens structure 15. By utilizing the converging effect of the convex lens structure 15 on light, the focal point 41 of the focusing unit 4 is formed in the imaging aperture 5. That is, the recognition light 6 passing through the focusing unit 4 converges in the imaging aperture 5.

[0046] In this embodiment of the invention, the specific film layer of the convex lens structure 15 is not limited. Those skilled in the art can set it according to actual needs. Any implementation method that achieves the focusing effect of the focusing unit 4 by setting the convex lens structure 15 is within the scope of the technical solution protected by this embodiment of the invention.

[0047] For example, this application provides several optional configurations of the convex lens structure 15. The specific configurations of the optional convex lens structure 15 provided by the present invention will be described below with reference to the accompanying drawings.

[0048] Optional, you can still refer to it. Figure 7 In one possible embodiment, the display panel may further include an optical adhesive layer 16, which is located between the organic light-emitting unit 1 and the color filter layer 13 in the second direction Y; the color filter layer 13 may further include a plurality of convex lens structures 15, which are located between adjacent color filters 14 in the first direction X, and the refractive index of the convex lens structures 15 is greater than the refractive index of the optical adhesive layer 16.

[0049] Specifically, such as Figure 7 As shown, an optical adhesive layer 16 can also be disposed within the display panel. In the second direction Y, the optical adhesive layer 16 is disposed between the organic light-emitting unit 1 and the color filter layer 13. The optical adhesive layer 16 can be used to achieve planarization of the internal film layers of the display panel, thereby improving the flatness of the display panel.

[0050] In this embodiment, a convex lens structure 15 can be configured to be on the same layer as the color filter layer 13, and multiple convex lens structures 15 are configured in the color filter layer 13. Furthermore, in the first direction X, the convex lens structures 15 are located between adjacent color filters 14, that is, the convex lens structures 15 and color filters 14 are spaced apart. In this configuration, the recognition light 6 reflected from an external object first passes through the convex lens structure 15, and then is focused into the imaging aperture 5 by the optical adhesive layer 16. Setting the refractive index of the convex lens structure 15 to be greater than that of the optical adhesive layer 16 improves the focusing ability of the convex lens structure 15, ensuring that the recognition light 6 is focused within the imaging aperture 5. In this embodiment, it can be configured as follows: Figure 7 The convex lens structure 15 shown is configured such that its convex surface is positioned close to the optical adhesive layer 16, thereby improving the focusing effect of the convex lens structure 15.

[0051] The specific values ​​of the refractive index of the convex lens structure 15 and the optical adhesive layer 16 are not limited in this embodiment of the invention. Those skilled in the art can set them according to the actual situation to ensure that the recognition light 6 is focused into the imaging aperture 5 after passing through the convex lens structure 15 and the optical adhesive layer 16.

[0052] Optional, Figure 8 This is a cross-sectional structural diagram of another display panel provided in an embodiment of the present invention, as shown below. Figure 8As shown, in another possible embodiment, the display panel may further include an optical adhesive layer 16, which is located between the organic light-emitting unit 1 and the color filter layer 13 in the second direction Y; the color filter layer 13 also includes a plurality of light-transmitting structures 17, which are located between adjacent color filters 14 in the first direction X; the optical adhesive layer 16 includes a plurality of convex lens structures 15, the refractive index of which is greater than that of the light-transmitting structures 17.

[0053] Specifically, such as Figure 8 As shown, in this embodiment, the optical adhesive layer 16 is still disposed between the organic light-emitting unit 1 and the color filter layer 13. Unlike the previous embodiment, in this embodiment, the color filter layer 13 is provided with a light-transmitting structure 17. In the first direction X, the light-transmitting structure 17 is located between adjacent color resists 14, that is, the light-transmitting structure 17 and the color resists 14 are spaced apart. The optical adhesive layer 16 is provided with multiple convex lens structures 15, which can be arranged one-to-one with the light-transmitting structure 17. In this arrangement, the reflected recognition light 6 will first pass through the light-transmitting structure 17 and then through the convex lens structure 15. At this time, the refractive index of the convex lens structure 15 can be set to be greater than the refractive index of the light-transmitting structure 17, reducing light reflection inside the display panel while ensuring that the recognition light 6 is focused into the imaging aperture 5 after passing through the light-transmitting structure 17 and the convex lens structure 15. In this embodiment, it can be arranged as follows: Figure 8 The convex lens structure 15 shown is configured such that the convex surface of the convex lens structure 15 can still be positioned close to the optical adhesive layer 16 to ensure the focusing effect of the convex lens structure 15.

[0054] Optional, Figure 9 A cross-sectional structural diagram of another display panel provided in an embodiment of the present invention, as shown below. Figure 9 As shown, in another possible embodiment, the display panel may further include a cover glass 18, which includes a plurality of convex lens structures 15; the color filter layer 13 further includes a plurality of light-transmitting structures 17, which are located between adjacent color filters 14 in the first direction X; the refractive index of the convex lens structure 15 is greater than the refractive index of the light-transmitting structure 17.

[0055] Specifically, such as Figure 9As shown, the display panel also includes a cover glass 18, which is disposed on the side of the color filter layer 13 away from the organic light-emitting unit 1, and the cover glass 18 can protect the display panel. In this embodiment, multiple convex lens structures 15 can be disposed in the cover glass 18. Correspondingly, multiple light-transmitting structures 17 can still be disposed in the color filter layer 13, with the light-transmitting structures 17 and color resist 14 spaced apart in the first direction X, and the light-transmitting structures 17 and convex lens structures 15 corresponding one-to-one. In this arrangement, the reflected recognition light 6 will first pass through the convex lens structure 15 in the cover glass 18, and then through the light-transmitting structure 17. At this time, the refractive index of the convex lens structure 15 can still be set to be greater than the refractive index of the light-transmitting structure 17 to ensure the refraction effect of the convex lens structure 15 on the recognition light 6.

[0056] Optional, Figure 10 This is a cross-sectional structural diagram of another display panel provided in an embodiment of the present invention, as shown below. Figure 10 As shown, in this embodiment, the display panel may further include an encapsulation layer 19, which is located on the side of the organic light-emitting unit 1 facing the color filter layer 13.

[0057] Specifically, refer to Figure 10 The display panel includes an encapsulation layer 19 disposed between the organic light-emitting unit 1 and the color filter layer 13. Specifically, the encapsulation layer 19 can be disposed on the side of the organic light-emitting unit 1 facing the color filter layer 13. The encapsulation layer 19 completely covers each organic light-emitting unit 1 to seal the organic light-emitting unit 1. This embodiment of the invention does not limit the specific arrangement of the encapsulation layer 19; those skilled in the art can configure the internal structure of the encapsulation layer 19 according to actual needs.

[0058] Still for reference Figure 10 In an exemplary embodiment, the encapsulation layer 19 may include at least one inorganic layer 191 and at least one organic layer 192 alternately stacked in the second direction Y; a plurality of convex lens structures 15 are formed in the at least one inorganic layer 191 and the at least one organic layer 192.

[0059] Specifically, in the second direction Y, the encapsulation layer 19 includes at least one inorganic layer 191 and at least one organic layer 192 alternately stacked to prevent water and oxygen from corroding the organic light-emitting unit 1. Figure 10 Only one inorganic layer 191 and one organic layer 192 are shown in the diagram. In reality, the encapsulation layer 19 may include any number of stacked inorganic layers 191 and organic layers 192.

[0060] In this configuration, the convex lens structure 15 can be disposed within the encapsulation layer 19, that is, multiple convex lens structures 15 are formed in at least one organic layer 191 and at least one inorganic layer 192.

[0061] Optional, you can still refer to it. Figure 10 In one possible embodiment, the display panel may further include a touch layer 20, which is located between the encapsulation layer 19 and the color filter layer 13. The touch layer 20 is used to implement the touch function of the display panel. Specifically, it can employ a self-capacitance method or a mutual capacitance method. The touch layer 20 may include multiple touch electrodes (not shown in the figure). Those skilled in the art can adjust the arrangement of the touch layer 20 according to actual needs; this invention will not describe this further.

[0062] Optional, Figure 11 This is a cross-sectional structural schematic diagram of another display panel provided in an embodiment of the present invention, with reference to... Figure 11 In one possible embodiment, the display panel may further include a polarizer 21 located on the light-emitting side of the organic light-emitting unit 1, and a plurality of convex lens structures 15 are formed in the polarizer 21.

[0063] Specifically, such as Figure 11 As shown, in this embodiment, a polarizer 21 can be disposed within the display panel. The polarizer 21 is located on the light-emitting side of the organic light-emitting unit 1, thus replacing the color filter layer 13 in the above embodiment with the polarizer 21. The presence of the polarizer 21 can also absorb reflected light from the external ambient light inside the display panel, improving the display effect of the display panel. When a polarizer 21 is disposed in the display panel, multiple convex lens structures 15 can be directly formed in the polarizer 21.

[0064] Of course, in other possible embodiments, when the polarizer 21 is used instead of the color filter layer 16, the optical adhesive layer 16, the encapsulation layer 19 and the touch layer 20 can still be set as in the above embodiments, and the specific arrangement of the convex lens structure 15 can also be adjusted as in the above embodiments, which will not be listed here.

[0065] Based on the same inventive concept, embodiments of the present invention also provide a display device. This display device includes the display panel 100 provided in any embodiment of the present invention. Therefore, the display device provided in the embodiments of the present invention possesses the corresponding beneficial effects of the display panel 100 provided in the embodiments of the present invention, which will not be elaborated further here. For example, the display device can be an electronic device such as a mobile phone, computer, smart wearable device (e.g., smartwatch), and in-vehicle display device; embodiments of the present invention do not limit this.
