Description

Technical Field

[0001] This application relates to the field of display device technology, and more specifically, to a display panel and an electronic device. Background Technology

[0002] With the development of display device manufacturing technology, in order to maximize the screen-to-body ratio and reduce the impact of the front camera area on the display effect, a sub-screen area that can display and transmit light is set in the display panel, and the camera is placed below the sub-screen area. However, the image acquisition effect of the under-display camera in this type of display panel is relatively poor. Summary of the Invention

[0003] To overcome the technical problems mentioned in the above background, embodiments of this application provide a display panel, the display panel comprising:

[0004] Array substrate;

[0005] Multiple mutually spaced pixel electrodes located on one side of the array substrate;

[0006] A first pixel defining portion and a second pixel defining portion are located on one side of the array substrate; the first pixel defining portion surrounds the pixel electrode and has a pixel opening that exposes the pixel electrode; the second pixel defining portion is located between adjacent first pixel defining portions; the light transmittance of the first pixel defining portion is less than the light transmittance of the second pixel defining portion;

[0007] A third pixel defining portion is located on the side of the first pixel defining portion away from the array substrate, and the orthographic projection of the third pixel defining portion on the array substrate is located within the orthographic projection of the first pixel defining portion on the array substrate.

[0008] In this way, by setting pixel boundaries with different transmittance around the pixel electrode, the abrupt change in transmittance at the edge of the pixel electrode can be reduced, thereby reducing the risk of light diffraction around the pixel electrode and improving the image acquisition effect of the under-display camera at the corresponding position.

[0009] In one possible implementation, the orthographic projection of the third pixel defining portion on the array substrate coincides with the edge of the orthographic projection of the pixel electrode on the array substrate;

[0010] Preferably, the first pixel defining portion covers the edge of the pixel electrode.

[0011] Thus, the edge outside the pixel electrode is the area with the lowest light transmittance, and continuing to extend outwards is a transition from the area with the lowest light transmittance to the area with the highest light transmittance, which can better avoid diffraction of external light.

[0012] In one possible implementation, the third pixel defining portion includes at least two sub-layers, wherein the orthographic projection of the sub-layer that is relatively farther away from the array substrate on the array substrate is located within the orthographic projection of the sub-layer that is relatively closer to the array substrate on the array substrate.

[0013] Preferably, the orthographic projection of the sublayer furthest from the array substrate on the array substrate coincides with the edge of the orthographic projection of the pixel electrode on the array substrate.

[0014] In this way, the edge positions of the pixel can have more orders of different transmittance, thereby better realizing the gradual change of transmittance and reducing light diffraction.

[0015] In one possible implementation, the distance between the outer edge of the orthographic projection of the first pixel defining portion on the array substrate and the outer edge of the orthographic projection of the pixel electrode on the array substrate is less than or equal to 3.5 micrometers;

[0016] Preferably, the display panel includes a main screen area and a secondary screen area; the first pixel defining portion and the third pixel defining portion are located in the secondary screen area.

[0017] In this way, the area occupied by the first pixel defining part can be avoided to be too large, and a second pixel defining part with high light transmittance with a sufficient area can be ensured between two adjacent pixel electrodes, so as to avoid excessive obstruction of external light.

[0018] In one possible implementation, the first pixel defining portion includes black organic adhesive, and the second pixel defining portion includes yellow organic adhesive.

[0019] Preferably, the third pixel defining portion includes black organic adhesive.

[0020] Thus, by setting a black organic adhesive with relatively low light transmittance around the pixel electrode, the stacking thickness of the pixel defining portion can be reduced while achieving a gradual change in light transmittance, thereby preventing the pixel defining portion from affecting other film layers of the display panel.

[0021] Another object of this application is to provide a display panel, the display panel comprising:

[0022] Array substrate;

[0023] Multiple mutually spaced pixel electrodes located on one side of the array substrate;

[0024] A fourth pixel defining portion located on one side of the array substrate, the fourth pixel defining portion having a pixel opening that exposes the pixel electrode;

[0025] A fifth pixel defining portion is located on the side of the fourth pixel defining portion away from the array substrate, and the orthographic projection of the fifth pixel defining portion on the array substrate surrounds the orthographic projection of the pixel electrode on the array substrate;

[0026] The fifth pixel defining portion includes at least two sub-layers, wherein the orthographic projection of the sub-layer that is relatively farther away from the array substrate on the array substrate is located within the orthographic projection of the sub-layer that is relatively closer to the array substrate on the array substrate.

[0027] In this way, by setting pixel boundaries with different transmittance around the pixel electrode, the abrupt change in transmittance at the edge of the pixel electrode can be reduced, thereby reducing the risk of light diffraction around the pixel electrode and improving the image acquisition effect of the under-display camera at the corresponding position.

[0028] In one possible implementation, the orthographic projection of the sublayer furthest from the array substrate in the fifth pixel definition portion on the array substrate coincides with the edge of the orthographic projection of the pixel electrode on the array substrate;

[0029] Preferably, the fourth pixel defining portion covers the edge of the pixel electrode.

[0030] Thus, starting from the edge outside the pixel electrode, the light transmittance transitions from the region with the lowest transmittance to the region with the highest transmittance, which can better prevent diffraction of external light.

[0031] In one possible implementation, the distance between the outer edge of the orthographic projection of the sublayer closest to the array substrate in the fifth pixel defining portion and the outer edge of the orthographic projection of the pixel electrode on the array substrate is less than or equal to 3.5 micrometers;

[0032] Preferably, the display panel includes a main screen area and a secondary screen area; the fourth pixel defining portion and the fifth pixel defining portion are located in the secondary screen area.

[0033] In this way, the area covered by the fifth pixel defining portion can be avoided to be too large, ensuring that a sufficient area of ​​the fourth pixel defining portion with high light transmittance is exposed between two adjacent pixel electrodes, thus avoiding excessive obstruction of external light.

[0034] In one possible implementation, the fifth pixel defining portion includes black organic adhesive, and the fourth pixel defining portion includes yellow organic adhesive.

[0035] Thus, by setting a black organic adhesive with relatively low light transmittance around the pixel electrode, the stacking thickness of the pixel defining portion can be reduced while achieving a gradual change in light transmittance, thereby avoiding the pixel defining portion from affecting other film layers of the display panel.

[0036] Another object of this application is to provide an electronic device, which includes the display panel provided in this application.

[0037] Compared with the prior art, this application has the following beneficial effects:

[0038] This application provides a display panel and an electronic device. By setting pixel demarcation portions with different light transmittance around the pixel electrodes, the abrupt change in light transmittance at the electrode edges can be reduced, thereby reducing the risk of light diffraction around the pixel electrodes and improving the image acquisition effect of the under-display camera at the corresponding position.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

In addition, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0051] It should be noted that, where there is no conflict, different features in the embodiments of this application can be combined with each other.

[0052] Through long-term research, the inventors discovered that in some display panels, to maximize the screen-to-body ratio and minimize the impact of the front-facing camera area on the display effect, a sub-screen area that can display and transmit light is set in the display panel, with the camera positioned below the sub-screen area. In such display panels, the sub-screen area includes opaque areas corresponding to the anode positions of the light-emitting pixels, with adjacent anodes spaced apart to form translucent areas. However, because the boundary between the opaque and translucent areas causes a sudden change in transmittance, diffraction easily occurs at this boundary as external light travels to the under-display camera, thus affecting the image acquisition performance of the under-display camera. Therefore, this application provides a display panel and electronic device to solve the above problems.

[0053] Please refer to Figure 1 , Figure 1 The display panel provided in this embodiment may include an array substrate 100, a pixel electrode 200, a first pixel defining portion 310, a second pixel defining portion 320 and a third pixel defining portion 330.

[0054] In this embodiment, the array substrate 100 may include a plurality of TFT (Thin Film Transistor) driving units arranged in an array.

[0055] Pixel electrodes 200 can be formed on the array substrate 100, with each pixel electrode 200 spaced apart from the others. Each pixel electrode 200 can be electrically connected to a driving unit on the array substrate 100. The pixel electrode 200 can be the anode of the light-emitting pixel, and typically the pixel electrode 200 is an opaque or extremely low light transmittance metal or metal oxide.

[0056] The second pixel defining portion 320 and the first pixel defining portion 310 are located on one side of the array substrate 100. In this embodiment, the display panel may include a plurality of first pixel defining portions 310, each first pixel defining portion 310 surrounding a pixel electrode 200 and having a pixel opening exposing the pixel electrode 200. For example, when the orthographic projection of the pixel electrode 200 on the array substrate 100 is circular, the orthographic projection of the first pixel defining portion 310 on the array substrate 100 may be an annulus surrounding the pixel electrode 200. The pixel opening formed by the first pixel defining portion 310 is mainly used to accommodate organic electroluminescent materials. Preferably, the first pixel defining portion 310 may cover the edge of the pixel electrode 200.

[0057] The second pixel defining portion 320 is located between adjacent first pixel defining portions 310 and fills the gap between adjacent first pixel defining portions 310. In this embodiment, the light transmittance of the first pixel defining portion 310 is less than the light transmittance of the second pixel defining portion 320. The area corresponding to the second pixel defining portion 320 is the main light-transmitting area in the display panel.

[0058] The third pixel defining portion 330 is located on the side of the first pixel defining portion 310 away from the array substrate 100, and the orthographic projection of the third pixel defining portion 330 on the array substrate 100 lies within the orthographic projection of the first pixel defining portion 310 on the array substrate 100. For example, if the orthographic projection of the first pixel defining portion 310 on the array substrate 100 is annular, and the orthographic projection of the third pixel defining portion 330 on the array substrate 100 is annular and coincides with the orthographic projection of the first pixel defining portion 310 on the array substrate 100, and the orthographic projection of the third pixel defining portion 330 on the array substrate 100 lies within the orthographic projection of the first pixel defining portion 310 on the array substrate 100, then the side of the first pixel defining portion 310 away from the array substrate 100 has an exposed area not covered by the third pixel defining portion 330, and this exposed area is located on the side of the first pixel defining portion 310 away from the pixel electrode 200. In other words, the third pixel defining portion 330 and the side of the first pixel defining portion 310 away from the pixel electrode 200 are distributed in a stepped manner.

[0059] Therefore, please refer to Figure 2The third pixel defining portion 330 and the first pixel defining portion 310 form a light-transmitting transition region at the edge of the pixel electrode 200. This transition region includes a first region A1 formed by the overlap of the third pixel defining portion 330 and the first pixel defining portion 310, a second region A2 including only the first pixel defining portion 310, and a third region A3 including only the second pixel defining portion 320. Since the light transmittance of the first pixel defining portion 310 is less than that of the second pixel defining portion 320, the light transmittance of the second region A2 is less than that of the third region A3. Furthermore, since the overall film thickness of the first region A1 is greater than that of the second region A2, the light transmittance of the first region A1 is less than that of the second region A2. In other words, the light transmittance of the first region A1 is less than that of the second region A2, which is less than that of the third region A3.

[0060] Based on the above design, in the display panel provided in this embodiment, by setting a first pixel defining part 310, a second pixel defining part 320 and a third pixel defining part 330, a transition area with at least three different transmittances is formed at the edge of the pixel electrode 200. This can reduce the sudden change in transmittance at the edge of the pixel electrode 200, thereby reducing the risk of light diffraction around the pixel electrode 200 and improving the image acquisition effect of the under-display camera at the corresponding position.

[0061] In one possible implementation, the first pixel defining portion 310 is made of a black organic adhesive with low light transmittance, and the second pixel defining portion 320 is made of a yellow organic adhesive with high light transmittance. Preferably, the third pixel defining portion 330 can be made of the same black organic adhesive as the first pixel defining portion 310. Thus, by providing a black organic adhesive with relatively low light transmittance around the pixel electrode 200, the stacking thickness of the pixel defining portions can be reduced while achieving a gradual change in light transmittance, thus preventing the pixel defining portions from affecting other film layers of the display panel.

[0062] In one possible implementation, the orthographic projection of the third pixel defining portion 330 onto the array substrate 100 coincides with the edge of the orthographic projection of the pixel electrode 200 onto the array substrate 100. For example, please refer again to... Figure 2 The first pixel defining portion 310 may include an edge coverage area covering the edge of the pixel electrode 200, and at least a portion of the third pixel defining portion 330 may be located on the edge coverage area of ​​the first pixel defining portion 310. In this way, the first region A1 with the lowest light transmittance starts from the edge outside the pixel electrode 200, and the area extending outward transitions from the region with the lowest light transmittance to the region with the highest light transmittance, which can better avoid diffraction of external light.

[0063] In one possible implementation, the third pixel defining portion 330 includes at least two sub-layers, wherein the orthographic projection of the sub-layer relatively farther from the array substrate 100 onto the array substrate 100 lies within the orthographic projection of the sub-layer relatively closer to the array substrate 100 onto the array substrate 100. For example, please refer to... Figure 3 The third pixel defining portion 330 may include a first sub-layer 331 that is relatively closer to the array substrate 100 and a second sub-layer 332 that is relatively farther away from the array substrate 100. The orthographic projection of the second sub-layer 332 on the array substrate 100 lies within the orthographic projection of the first sub-layer 331 on the array substrate 100, and the side of the first sub-layer 331 away from the array substrate 100 has an exposed area not covered by the second sub-layer 332. In this way, the edge position of the pixel electrode 200 can have more orders of different transmittance, thereby better realizing the gradient of transmittance and reducing light diffraction.

[0064] It should be noted that, in this embodiment, the number of sub-layers included in the third pixel defining portion 330 is not limited to... Figure 3 In other implementations of this embodiment, the third pixel defining portion 330 may include a greater number of sub-layers, as shown in the two-layer diagram. No specific limitation is made here.

[0065] Preferably, in this embodiment, the orthographic projection of the sublayer furthest from the array substrate 100 on the array substrate 100 coincides with the edge of the orthographic projection of the pixel electrode 200 on the array substrate 100. In this way, the area outside the pixel electrode 200 transitions from the region with the lowest light transmittance to the region with the highest light transmittance, which can better avoid diffraction of external light.

[0066] In one possible implementation, please see Figure 4 The distance D1 between the outer edge of the orthographic projection of the first pixel defining portion 310 on the array substrate 100 and the outer edge of the orthographic projection of the pixel electrode 200 on the array substrate 100 is less than or equal to 3.5 micrometers. This avoids the first pixel defining portion 310 occupying an excessively large area, ensuring that there is a sufficiently large area of ​​a second pixel defining portion 320 with high light transmittance between two adjacent pixel electrodes 200, thus preventing excessive obstruction of external light.

[0067] In one possible implementation, the display panel provided in this embodiment includes a main screen area and a sub-screen area located within the main screen area. The sub-screen area can be a light-transmitting display area for housing an under-display camera, with the first pixel defining portion 310 and the third pixel defining portion 330 located around the pixel electrodes 200 in the sub-screen area. Furthermore, for the main screen area, since light transmission between the pixel electrodes 200 is not required, only pixel defining portions with low light transmittance can be uniformly provided between the pixel electrodes 200 in the main screen area.

[0068] In addition, the display panel provided in this embodiment may also include an organic electroluminescent material located in the pixel opening, a common electrode layer (e.g., a cathode layer) located on the side of the organic electroluminescent material away from the array substrate 100, other protective film layers, encapsulation film layers and / or touch film layers, etc., which will not be described in detail here.

[0069] Please refer to Figure 5 The figure shows a display panel provided in this embodiment. The display panel may include an array substrate 100, a pixel electrode 200, a fourth pixel defining portion 340, and a fifth pixel defining portion 350.

[0070] In this embodiment, the array substrate 100 may be a substrate comprising a plurality of TFT (Thin Film Transistor) driving units arranged in an array.

[0071] Pixel electrodes 200 can be formed on the array substrate 100, with each pixel electrode 200 spaced apart from the others. Each pixel electrode 200 can be electrically connected to a driving unit on the array substrate 100. The pixel electrode 200 can be the anode of the light-emitting pixel, and typically the pixel electrode 200 is an opaque or extremely low light transmittance metal or metal oxide.

[0072] The fourth pixel defining portion 340 is located on one side of the array substrate 100. The fourth pixel defining portion 340 can fill the gap between adjacent pixel electrodes 200, and the fourth pixel defining portion 340 has a pixel opening that exposes the pixel electrode 200. The pixel opening is mainly used for subsequent accommodating organic electroluminescent materials. Preferably, the fourth pixel defining portion 340 can cover the edge of the pixel electrode 200.

[0073] The fifth pixel defining portion 350 is located on the side of the fourth pixel defining portion 340 away from the array substrate 100, and the orthographic projection of the fifth pixel defining portion 350 on the array substrate 100 surrounds the orthographic projection of the pixel electrode 200 on the array substrate 100.

[0074] The fifth pixel defining portion 350 includes at least two sub-layers, wherein the orthographic projection of the sub-layer relatively farther from the array substrate 100 on the array substrate 100 lies within the orthographic projection of the sub-layer relatively closer to the array substrate 100 on the array substrate 100. For example, please refer again to... Figure 5 The fifth pixel defining portion 350 may include a third sub-layer 351 that is relatively closer to the array substrate 100 and a fourth sub-layer 352 that is relatively farther away from the array substrate 100. The orthographic projection of the fourth sub-layer 352 on the array substrate 100 is located within the orthographic projection of the third sub-layer 351 on the array substrate 100, and the side of the third sub-layer 351 that is farther away from the array substrate 100 has an exposed area that is not covered by the fourth sub-layer 352.

[0075] Therefore, please refer to Figure 6 Since the thicker the film layer, the lower the light transmittance, by setting at least two sub-layers of the fifth pixel defining portion 350 and the fourth pixel defining portion 340 in a stepped distribution, a transition region with at least three different light transmittances can be formed at the edge of the pixel electrode 200. This can reduce the abrupt change in light transmittance at the edge of the pixel electrode 200, thereby reducing the risk of light diffraction around the pixel electrode 200 and improving the image acquisition effect of the under-display camera at the corresponding position.

[0076] For example, please refer to Figure 6 Taking the fifth pixel defining portion 350, which includes two sub-layers, as an example, the two sub-layers of the fifth pixel defining portion 350 and the fourth pixel defining portion 340 form a light-transmitting transition region at the edge of the pixel electrode 200. This transition region includes a fourth region A4 formed by stacking the third sub-layer 351, the fourth sub-layer 352, and the fourth pixel defining portion 340 of the fifth pixel defining portion 350; a fifth region A5 formed by stacking the third sub-layer 351 and the fourth pixel defining portion 340; and a sixth region A6 consisting only of the fourth pixel defining portion 340. In terms of the number of stacked film layers, the fourth region A4 > the fifth region A5 > the sixth region A6. Therefore, in terms of light transmittance, the fourth region A4 < the fifth region A5 < the sixth region A6. This creates a transition region with three different light transmittance gradients at the edge of the pixel electrode 200, reducing abrupt changes in light transmittance at the edge of the pixel electrode 200.

[0077] It should be noted that, in this embodiment, the number of sub-layers included in the fifth pixel defining portion 350 is not limited to... Figure 5 As shown on both sides, in other implementations of this embodiment, the fifth pixel defining portion 350 may include a greater number of sub-layers, which are not specifically limited here.

[0078] In one possible implementation, the fifth pixel defining portion 350 includes a black organic adhesive with low light transmittance, and the fourth pixel defining portion 340 includes a yellow organic adhesive with high light transmittance. Thus, by providing a black organic adhesive with relatively low light transmittance around the pixel electrode 200, the stacking thickness of the pixel defining portions can be reduced while achieving a gradual change in light transmittance, preventing the pixel defining portions from affecting other film layers of the display panel.

[0079] In one possible implementation, the orthographic projection of the sublayer furthest from the array substrate 100 in the fifth pixel defining portion 350 onto the array substrate 100 coincides with the edge of the orthographic projection of the pixel electrode 200 onto the array substrate 100. Thus, the area transitions from the region of lowest light transmittance to the region of highest light transmittance starting from the edge outside the pixel electrode 200, better preventing diffraction of external light.

[0080] In one possible implementation, please refer to Figure 7 The distance D2 between the outer edge of the orthographic projection of the sublayer closest to the array substrate 100 in the fifth pixel defining portion 350 and the outer edge of the orthographic projection of the pixel electrode 200 on the array substrate 100 is less than or equal to 3.5 micrometers. This avoids the fifth pixel defining portion 350 covering an excessively large area, ensuring that a sufficiently large area of ​​the fourth pixel defining portion 340 with high light transmittance is exposed between two adjacent pixel electrodes 200, thus preventing excessive obstruction of external light.

[0081] In one possible implementation, the display panel provided in this embodiment includes a main screen area and a sub-screen area located within the main screen area. The sub-screen area can be used to house the light-transmitting display area of ​​an under-display camera. The fourth pixel defining portion 340 and the fifth pixel defining portion 350 are located around the pixel electrodes 200 in the sub-screen area. Furthermore, for the main screen area, since light transmission between the pixel electrodes 200 is not required, only pixel defining portions with low light transmittance can be uniformly provided between the pixel electrodes 200 in the main screen area.

[0082] This application also provides an electronic device, which may include the display panel provided in this application. The electronic device may include devices with display functions such as mobile phones, tablets, laptops, and smart wearable devices. Preferably, the electronic device may include a device with display function and an under-display camera.

[0083] In addition, the display panel provided in this embodiment may also include an organic electroluminescent material located in the pixel opening, a common electrode layer (e.g., a cathode layer) located on the side of the organic electroluminescent material away from the array substrate 100, other protective film layers, encapsulation film layers and / or touch film layers, etc., which will not be described in detail here.

[0084] In summary, the embodiments of this application provide a display panel and an electronic device. By setting pixel demarcation portions with different transmittance around the pixel electrodes, the abrupt change in transmittance at the edge of the pixel electrodes can be reduced, thereby reducing the risk of light diffraction around the pixel electrodes and improving the image acquisition effect of the under-display camera at the corresponding position.
