Obviously, the described embodiments are only some of the embodiments of the present application, rather than all of them. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0029] In the following description, specific details such as specific system structures, interfaces, and technologies are proposed for the purpose of illustration rather than limitation, so as to thoroughly understand the present application.

[0030] The terms "first", "second", and "third" in this application are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", and "third" may explicitly or implicitly include at least one of the said features. In the description of this application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically defined. All directional indications (such as up, down, left, right, front, back...) in the embodiments of this application are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will change accordingly.

[0031] Referring to "embodiments" herein means that specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appearing in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0032] The following describes this application in detail with reference to the drawings and embodiments.

[0033] Due to the advantages of a full-screen display such as a beautiful appearance and a better visual experience, it is widely favored by consumers. To implement the full-screen technology, the camera needs to be placed under the light-emitting unit. The light-emitting unit includes a plurality of pixel points, and light can only reach the camera through the gaps between the pixel points. While implementing the full-screen display, it is necessary to ensure the imaging quality of the camera so that functions such as face recognition are not affected.

[0034] Currently, all OLED (Organic Light-Emitting Diode) screens on the market are top-emitting, and top-emitting means that the light emitted by the OLED must pass through the cathode metal layer. A large number of reflected light rays will be formed while the light passes through the cathode metal layer, and some of the reflected light rays will be collected by the camera and become stray light that seriously affects the imaging quality of the camera.

[0035] Regarding how to improve the imaging quality of an under-screen camera, the commonly adopted method in the prior art is to reduce the pixel density (PPI) of the light-emitting unit corresponding to the camera area to increase the light-transmitting area of the under-screen light-emitting unit corresponding to the camera area, so that sufficient ambient light energy can reach the camera, ensuring that the camera can capture a clear image and thus improving the imaging quality of the camera. However, continuously increasing the light-transmitting area of the under-screen light-emitting unit corresponding to the camera area will cause an increase in the reflectivity. The reflected light makes the brightness of the area corresponding to the camera under the screen significantly higher than the surrounding area when the screen is off or at low gray-scale brightness, seriously affecting the user's visual experience and losing the true meaning of the under-screen camera technology. In view of this, the present application provides a display panel and an electronic device.

[0036] Please refer to Figures 1 to 3 , Figure 1 which is a schematic structural diagram of the display panel provided in the first embodiment of the present application. Figure 2 It is Figure 1 a schematic structural diagram of the first implementation manner of the cathode layer in the display panel provided. Figure 3 It is Figure 1 a schematic structural diagram of the second implementation manner of the cathode layer in the display panel provided.

[0037] Referring to Figure 1 , in the present application Figure 1 only a partial schematic structural diagram of the display panel located in the acquisition area of the image acquirer 11 is given. The display panel provided in the first embodiment of the present application includes an image acquirer 11, an anode layer 12, a light-emitting layer 13, and a cathode layer 14. The anode layer 12, the light-emitting layer 13, and the cathode layer 14 are sequentially stacked, and the image acquirer 11 is disposed on the side of the anode layer 12 away from the light-emitting layer 13. A groove 141 or a protrusion 142 is provided on the surface of the cathode layer 14 close to the light-emitting layer 13, and the groove 141 or the protrusion 142 is used to reflect the light emitted from the light-emitting layer 13 to the cathode layer 14 outside the acquisition area of the image acquirer 11.

[0038] By providing grooves 141 and / or protrusions 142 on the surface of the cathode layer 14 close to the light-emitting layer 13, the light emitted from the light-emitting layer 13 to the cathode layer 14 is reflected outside the acquisition area of the image acquirer 11 by the grooves 141 or protrusions 142, preventing the reflected light from being acquired by the image acquirer 11, reducing the crosstalk of the reflected light, effectively improving the imaging quality of the image acquirer 11, and contributing to enhancing functions such as self-portrait experience, face recognition, and fingerprint recognition of the full-screen electronic device. It can be understood that providing grooves 141 and / or protrusions 142 on the surface of the cathode layer 14 close to the light-emitting layer 13 will not affect the pixel density in the light-emitting layer 13 corresponding to the image acquirer 11. Therefore, compared with the prior art method of improving the imaging quality by reducing the pixel density of the light-emitting unit corresponding to the camera area, the transmittance of ambient light and the reflectivity of the light emitted from the light-emitting layer 13 to the cathode layer 14 can be taken into account, avoiding the area corresponding to the image acquirer 11 under the screen being too bright when the screen is off or at low gray-scale brightness due to high reflectivity, which is beneficial to improving the aesthetics and visual experience of the full screen.

[0039] Optionally, the image acquirer 11 is a camera or a light sensor.

[0040] Optionally, grooves 141 are provided on the surface of the cathode layer 14 close to the light-emitting layer 13, and the inner surface of the grooves 141 is an arc surface or a folded surface (as Figure 2 shown). Since the inner surface of the grooves 141 is an arc surface or a folded surface, the normal line corresponding to the light emitted from the light-emitting layer 13 into the grooves 141 forms an angle with the vertical direction, so that the reflected light deviates from the original specular reflection path, and the angle between the reflected light and the vertical direction increases, reflecting the reflected light outside the acquisition area of the image acquirer 11, preventing the reflected light from causing crosstalk to the image acquirer 11, improving the contrast of the image formed on the object surface, and improving the imaging quality of the image acquirer 11 under the screen. When the opening width of the grooves 141 is determined, the arc length of the grooves 141 is maximized as much as possible. It can be understood that the grooves 141 can be formed by etching the surface of the cathode layer 14 close to the light-emitting layer 13, or multiple protrusions 142 can be deposited on the surface of the cathode layer 14 close to the light-emitting layer 13, and grooves 141 are formed between two adjacent protrusions 142, and the side surfaces of the protrusions 142 are arc surfaces or folded surfaces.

[0041] Optionally, protrusions 142 are provided on the surface of the cathode layer 14 close to the light-emitting layer 13, and the outer surface of the protrusions 142 is an arc surface or a folded surface (as Figure 3As shown. Since the outer surface of the protrusion 142 is an arc surface or a folded surface, the normal line corresponding to the light emitted from the light-emitting layer 13 to the protrusion 142 forms an angle with the vertical direction, so that the reflected light deviates from the original specular reflection path, and the angle between the reflected light and the vertical direction increases, reflecting the reflected light outside the acquisition area of the image acquirer 11, avoiding crosstalk of the reflected light to the image acquirer 11, improving the contrast of the image formed on the object surface, and improving the imaging quality of the under-screen image acquirer 11. When the end width of the protrusion 142 is determined, the arc length of the protrusion 142 is maximized as much as possible. It can be understood that the protrusion 142 on the surface of the cathode layer 14 can be formed by deposition.

[0042] Optionally, the surface of the cathode layer 14 close to the light-emitting layer 13 is provided with a protrusion 142 and a groove 141. Among them, the protrusion 142 can refer to Figure 3 the protrusion 142 shown in Figure 2 , and the groove 141 can refer to Figure 2 the groove 141 shown in Figure 3 . Exemplarily,

[0043] Optionally, the inner surface of the groove 141 or the outer surface of the protrusion 142 is a rough surface, avoiding specular reflection of the light emitted from the light-emitting layer 13 to the cathode layer 14, facilitating the reflection of the reflected light outside the acquisition area of the image acquirer 11, avoiding crosstalk of the reflected light to the image acquirer 11, and facilitating the improvement of the imaging quality of the under-screen image acquirer 11.

[0044] It can be understood that Figure 2 the groove 141 of the cathode layer 14 shown in Figure 3 and the protrusion 142 of the cathode layer 14 shown in Figure 2 can achieve the same technical effect. Now, taking the cathode layer 14 shown in Figure 3 as an example, the specific setting method of the groove 141 is introduced in detail, and the setting method of the protrusion 142 of the cathode layer 14 shown in

[0045] can refer to the setting method of the groove 141. Figure 1 , Figure 4 and Figure 5, the light-emitting layer 13 includes a plurality of pixel points 131, each pixel point 131 corresponds to a groove 141, the shape of the groove 141 is annular, and the projection of the groove 141 on the light-emitting layer 13 surrounds the pixel point 131. Since the groove 141 is arranged to surround the pixel point 131, the projection of the groove 141 on the light-emitting layer 13 does not overlap with the pixel point 131, avoiding the groove 141 from reflecting the light emitted by the pixel point 131 that should originally pass through the cathode layer 14, resulting in a decrease in the transmittance of the light emitted by the pixel point 131, and further avoiding a decrease in the light extraction efficiency of the light-emitting layer 13; and along the circumferential direction of the pixel point 131, the light emitted to the cathode layer 14 is reflected outside the acquisition area of the image acquisition device 11.

[0046] Optionally, the inner side of the opening of the groove 141 coincides with the outer contour of the pixel point 131 in the projection on the light-emitting layer 13, and the outer side of the opening of the groove 141 is located between two adjacent pixel points 131 in the projection on the light-emitting layer 13 (please refer to Figure 4 , Figure 4 is the positional relationship diagram of the first embodiment of the projection of the groove and the pixel point).

[0047] Optionally, the projection of the groove 141 on the light-emitting layer 13 is completely located between two adjacent pixel points 131, and the projection of the groove 141 on the light-emitting layer 13 is spaced apart from the pixel points 131 of the light-emitting layer 13 (please refer to Figure 5 , Figure 5 is the positional relationship diagram of the second embodiment of the projection of the groove and the pixel point).

[0048] Optionally, the opening width of the groove 141 is less than half of the distance between two adjacent pixel points 131, where the opening width of the groove refers to: the maximum width of the groove in the direction parallel to the surface of the light-emitting layer. It can be understood that the width of the protrusion 142 is less than half of the distance between two adjacent pixel points 131, where the width of the protrusion 142 refers to: the maximum width of the protrusion in the direction parallel to the surface of the light-emitting layer.

[0049] Optionally, the shape of the groove 141 is correspondingly set according to the contour of the pixel point 131. For example, if the contour of the pixel point 131 is circular, the shape of the groove 141 is a ring. For another example, if the contour of the pixel point 131 is square, the shape of the groove 141 is a square ring.

[0050] Please refer to Figure 6 and Figure 7 , Figure 6 is the schematic structural diagram of the display panel provided by the second embodiment of the present application, Figure 7 is Figure 6 the schematic top view structure diagram of the cathode layer and the light-emitting layer in the provided display panel.

[0051] Figure 6The provided display panel is Figure 1 basically the same in structure as the provided display panel, except for: the specific setting manner of the groove 141.

[0052] Figure 7 The dashed line in

[0053] is the contour of the pixel 131. Specifically, a plurality of grooves 141 are provided on the surface of the cathode layer 14 close to the light-emitting layer 13, and the shape of the groove 141 is annular. A part of the projection of one groove 141 on the light-emitting layer 13 covers the pixel 131, and the other part is located in the gap between two adjacent pixels 131; and the width of the part of the projection of the groove 141 on the light-emitting layer 13 located in the gap between two adjacent pixels 131 is less than half of the distance between two adjacent pixels 131, and the width of the part of the projection of the groove 141 on the light-emitting layer 13 covering the pixel 131 is less than 1 / 10 of the width of the pixel 131. Among them, when the pixel 131 is circular, the width of the pixel 131 is its diameter.

[0054] Please refer to Figure 8 , Figure 8 which is a schematic bottom view of the cathode layer and the light-emitting layer of the display panel provided in the third embodiment of the present application.

[0055] Figure 8 The provided display panel is Figure 1 basically the same in structure as the provided display panel, except for: the specific setting manner of the groove 141.

[0056] A plurality of grooves 141 are provided on the surface of the cathode layer 14 close to the light-emitting layer 13. One section of the groove 141 is shared between two adjacent pixels 131; that is, only one section of the groove 141 is provided between two adjacent pixels 131, and the groove 141 is used to reflect the light emitted by two adjacent pixels 131 out of the collection area of the image collector 11. The projection of the groove 141 on the light-emitting layer 13 is completely located in the gap between two adjacent pixels 131 and is spaced from the pixel 131.

[0057] It can be understood that in Figure 9 only three pixels 131 are schematically shown. In practice, a plurality of pixels 131 are provided on the display panel, and the shape of the pixel 131 may not be rectangular. In the circumferential direction of each pixel 131, it may be adjacent to two or more pixels 131, and one section of the groove 141 is shared between any two adjacent pixels 131.

[0058] Please refer to Figure 9 , Figure 9 , which is a schematic structural diagram of a display panel provided by the fourth embodiment of the present application.

[0059] Figure 9 The display panel provided is basically the same as the display panel provided by Figure 1 , except for the specific setting method of the groove 141.

[0060] A plurality of grooves 141 are provided on the surface of the cathode layer 14 close to the light-emitting layer 13. The projection of one groove 141 on the light-emitting layer 13 completely covers the gap between two adjacent pixel points 131. That is, a section of the groove 141 is shared between two adjacent pixel points 131; specifically, only one section of the groove 141 is provided between two adjacent pixel points 131, and the groove 141 is used to reflect the light emitted by the two adjacent pixel points 131 outside the acquisition area of the image acquisition device 11.

[0061] Optionally, the opening width of the groove 141 is equal to the distance between two adjacent pixel points 131. Since the opening width of the groove 141 is equal to the distance between two adjacent pixel points 131, the projection of the groove 141 on the light-emitting layer 13 does not overlap with the pixel points 131, avoiding the groove 141 from reflecting the light that should pass through the cathode layer 14 emitted by the pixel points 131, resulting in a reduction in the transmittance of the light emitted by the pixel points 131, and further avoiding the reduction of the light extraction efficiency of the light-emitting layer 13; and along the circumferential direction of the pixel points 131, the light emitted to the cathode layer 14 is reflected outside the acquisition area of the image acquisition device 11.

[0062] Optionally, the opening width of the groove 141 may also be greater than the distance between two adjacent pixel points 131. That is, the projection of the groove 141 on the light-emitting layer 13 covers the gap between two adjacent pixel points 131 and also covers part of the pixel points 131. The width of the part of the projection of the groove 141 on the light-emitting layer 13 covering the pixel points 131 is less than 1 / 10 of the width of the pixel points 131. On the premise that the groove 141 has little influence on the light extraction efficiency of the light-emitting layer 13, it is beneficial to reduce the assembly accuracy between the groove 141 of the cathode layer 14 and the pixel points 131. It can be understood that the projection of the groove 141 on the light-emitting layer 13 covers one or two parts of two adjacent pixel points.

[0063] It can be understood that the setting method of the protrusion 142 of the cathode layer 14 can refer to the setting method of the above-mentioned groove 141, which will not be elaborated here.

[0064] The display panel further includes a packaging layer (not shown in the figure), a polarizer (not shown in the figure), and a cover plate (not shown in the figure). The packaging layer, the polarizer, and the cover plate are sequentially stacked on the side of the cathode layer 14 away from the light-emitting layer 13. The functions of the packaging layer, the polarizer, and the cover plate can be referred to the prior art and will not be elaborated here.

[0065] The present application also provides an electronic device, which includes the display panel provided in any of the above embodiments, facilitating to improve the imaging quality of the electronic device for taking pictures and fingerprint recognition. The electronic device can be a mobile phone, a tablet computer, a car central control, a wearable product, etc.

[0066] The above are only the embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
