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

[0002] OLED (Organic Light Emitting Diode) display panels have gradually gained widespread attention due to their advantages such as wide viewing angles, high contrast, fast response times, and flexible fabrication capabilities.

[0003] Currently, in order to meet users' requirements for full-screen displays, OLED display panels need to be designed with a transparent display area in the display area to meet the light transmission requirements of devices such as cameras.

The display panel includes a first display area, a second display area, and a third display area on a substrate. The first display area has a smaller aperture ratio for its display pixels, meeting the high transmittance requirement of the first display area, making it suitable as a high-transmittance area for mounting functional components such as cameras.

This helps reduce the shape difference of the display pixels in these two areas, improving the display abrupt change phenomenon caused by the abrupt change in the aperture ratio of the display pixels, and is particularly beneficial for improving display differences at large viewing angles in the predetermined direction.

[0038] The technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this specification.

[0039] Application Overview

[0040] The inventors of this specification noted during their research that, in order to meet the requirements of a full-screen display, the shape of the display pixels typically needs to be specially designed within the area where functional devices such as cameras are located (i.e., the transparent display area). For example, refer to... Figure 1 Unlike the rectangular opening shape of the display pixel P1 in the normal display area AA1, the opening shape of the display pixel P2 in the transparent display area AA2 is mostly circular or elliptical, in order to reduce the diffraction phenomenon of light passing through the transparent display area and meet the light requirements of functional devices such as cameras.

[0041] But for reference Figure 2 , Figure 2 for Figure 1 The schematic diagram of the cross-sectional structure of the display panel shown is from... Figure 2 As can be seen, the display pixel consists of a pixel circuit located on the substrate 1, an anode 8, a light-emitting layer 10 located in the recessed area (i.e., pixel opening) of the pixel definition layer 9 (PDL), and a cathode 11 located on the side of the light-emitting layer 10 facing away from the substrate 1. A photo spacer 12 is provided on at least one side of at least a portion of the recessed area. The pixel circuit includes at least one thin-film transistor (TFT) and a capacitor, still referring to... Figure 2 The thin-film transistor includes a gate 2, an active region 4, a source, and a drain 6. The drain 6 is electrically connected to the anode 8. The active region 4 includes a source region, a drain region, and a channel located between the source and drain regions. The source and source regions are electrically connected, and the drain 6 is electrically connected to the drain region. In addition, Figure 2 The diagram also shows some insulating layers, such as gate insulating layer 3, etch barrier layer 5, and planarization layer 7.

[0042] refer to Figure 2 and in conjunction with references Figure 1 Because the light-emitting layer 10 is positioned relatively low compared to the pixel definition layer 9 and the isolation pillars 12, some of the light emitted by the light-emitting layer 10 is blocked by the pixel definition layer 9 and / or the isolation pillars 12. It is easy to understand that, due to the blocking of light by the pixel definition layer 9 and / or the isolation pillars 12, as the viewing angle increases, the human eye receives less light emitted from the pixel, resulting in lower brightness in the pixel's area. Due to the difference in the shape of the display pixels in the transparent display area AA2 and the normal display area AA1, the degree of light blocking varies between these two areas as the viewing angle increases. This leads to inconsistencies in the display of the transparent display area AA2 and the normal display area AA1, making the user clearly perceive differences in display parameters (such as brightness) between the two areas, resulting in a poor viewing experience.

[0043] To address this issue, the inventors of this specification, after further research, proposed a display panel comprising a first display area, a second display area, and a third display area on a substrate. The first display area has a smaller aperture ratio for its pixels, satisfying its high transmittance requirements and allowing it to serve as a high-transmittance area for mounting functional components such as cameras. Furthermore, a second display area is provided between the first and third display areas for transition. The aperture ratio of the pixels in the second display area is smaller than that in the third display area, and the length of the pixels in the second display area in a predetermined direction is less than or equal to the length of the pixels in the third display area in the predetermined direction. This helps reduce the shape difference between the pixels in the second and third display areas, thereby improving the display abruptness caused by sudden changes in pixel aperture ratio, particularly beneficial for improving display differences at large viewing angles in the predetermined direction.

[0044] The following examples or embodiments provide a non-limiting description of the display panel provided in the embodiments of this specification. As described below, different features in these specific examples or embodiments can be combined with each other without conflict to obtain new examples or embodiments, and these new examples or embodiments also fall within the scope of protection of this disclosure.

[0045] Exemplary display panel

[0046] Figure 3 This is a top view of the display panel provided in an exemplary embodiment of this specification. Figure 4 yes Figure 3 An enlarged view of the dashed box K in the middle, for reference. Figure 3 In conjunction with references Figure 4 The display panel provided in the embodiments of this specification includes:

[0047] The substrate 100 includes a first display area 101, a second display area 102 and a third display area 103, wherein the second display area 102 is at least partially disposed outside the first display area 101 and the third display area 103 is at least partially disposed outside the second display area 102.

[0048] The display pixels 104 distributed on the substrate 100, among display pixels 104 of the same color, have a smaller aperture ratio in the first display area 101 and the second display area 102 than in the third display area 103. The length of the display pixels 104 in the second display area 102 in a predetermined direction is less than or equal to the length of the display pixels 104 in the third display area 103 in that predetermined direction. Optionally, the predetermined direction is parallel to the substrate 100.

[0049] from Figure 3 As can be seen, the first display area 101, the second display area 102, and the third display area 103 constitute a complete display area. The first display area 101 can also be used as a transparent display area, and its side facing away from the light-emitting direction can be used to place functional components such as cameras. In addition to... Figure 3 In addition to the second display area 102 completely surrounding the first display area 101 and the third display area 103 completely surrounding the first display area 102, in some embodiments of this specification, the second display area 102 may also partially surround the first display area 101, and the third display area 103 may also partially surround the second display area 102. Furthermore, besides as shown... Figure 3 In addition to the first display area 101 and the second display area 102 being circular areas, in other embodiments of this specification, the first display area 101 and the second display area 102 may also be areas of other shapes, such as rectangles, etc., and this specification does not limit them to these shapes.

[0050] In some embodiments of this specification, the preset direction refers to a direction parallel to the substrate, for example, it may be as follows: Figure 3 When the length of the display pixels 104 distributed in the second display area 102 in the preset direction is less than or equal to the length of the display pixels 104 distributed in the third display area 103 in the preset direction, it is beneficial to reduce the shape difference of the display pixels 104 in these two areas. When the user views the display screen from a large viewing angle in the preset direction, the degree of change in the portion of the light emitted from the display pixels 104 in the second display area 102 and the third display area 103 that is blocked is similar, which is beneficial to improving the display abrupt change phenomenon caused by the abrupt change in the aperture ratio of the display pixels, and is particularly beneficial to improving the display difference at a large viewing angle in the preset direction. Optionally, in one embodiment of this specification, the length of the display pixels 104 distributed in the second display area 102 in the preset direction is equal to the length of the display pixels 104 distributed in the third display area 103 in the preset direction. In this way, the difference between the display pixels 104 in the second display area 102 and the third display area 103 can be minimized in the preset direction, thereby optimizing the display effect.

[0051] Furthermore, in this embodiment, when all display pixels 104 in the display panel are used to emit light of the same color, the aforementioned optimization design for display pixels 104 in different display areas can also improve the consistency of parameters such as brightness between the second display area 102 and the third display area 103 at wide viewing angles. When the display panel includes display pixels 104 of different colors, corresponding optimization designs are made for display pixels 104 of different colors in the second display area 102, which also helps to improve the color shift consistency between the second display area 102 and the third display area 103 at wide viewing angles, thereby improving display consistency at wide viewing angles.

[0052] The display panel typically also includes a pixel definition layer, isolation pillars, and other structures. The pixel definition layer is located between the substrate and the display pixels, and includes multiple pixel openings for housing the display pixels 104. The isolation pillars are located on the side of the pixel definition layer facing away from the substrate, and the orthographic projection of the isolation pillars onto the substrate does not overlap with the orthographic projection of the display pixels onto the substrate.

[0053] In one exemplary embodiment of this specification, reference is still made to... Figure 3 and Figure 4 The length of the display pixels 104 distributed in the second display area 102 in the preset direction is greater than the length of the display pixels 104 distributed in the first display area 101 in the preset direction. This ensures that, with the aperture ratios of the display pixels in the second display area 102 and the first display area 101 being similar, the length of the second display area 102 in the preset direction is as close as possible to the length of the display pixels 104 in the preset direction, thereby reducing the shape difference of the display pixels 104 located in the second display area 102 and the third display area 103.

[0054] In one exemplary embodiment of this specification, reference is made to Figure 5 and in conjunction with references Figure 4 The preset direction includes a first direction DR1 and a second direction DR2, which are parallel to the substrate 100. The first direction DR1 is parallel to the extension direction of a first side of the substrate, and the second direction is parallel to the extension direction of a second side of the substrate. The first side and the second side are two intersecting sides of the substrate.

[0055] When the substrate 100 is rectangular, the first side and the second side can be the long side and the short side of the substrate 100, respectively. When the substrate 100 is square, the first side and the second side can be the two right-angled sides of the substrate 100.

[0056] In this embodiment, as Figure 4 and Figure 5 As shown, the length of the display pixel 104 in the second display area 102 along the first direction DR1 and the second direction DR2 is the same as the length of the display pixel 104 in the third display area 103 (i.e., Figure 4 The formula (H1=H2, L1=L2) helps to improve the display difference at large viewing angles in these two directions. The first direction DR1 and the second direction DR2 are the two most commonly used directions for users to view the display panel, which helps to optimize the user experience.

[0057] In one embodiment of this specification, reference is made to Figure 6 The orthographic projection shape of the display pixel 104 located in the second display area 102 on the substrate 100 includes at least one first strip pattern 1041 and at least one second strip pattern 1042. The extension direction of the first strip pattern 1041 is parallel to the first direction DR1, and the extension direction of the second strip pattern 1042 is parallel to the second direction DR2.

[0058] In the same color display pixels 104, the length of the first bar pattern 1041 is equal to the length of the display pixel 104 in the third display area 103 in the first direction DR1, and the length of the second bar pattern 1042 is equal to the length of the display pixel 104 in the third display area 103 in the second direction DR2.

[0059] When the display pixels are OLED pixels, the sizes of display pixels of different colors are usually different due to differences in the lifespan and luminous efficiency of the light-emitting layers. In some embodiments, the display pixels emitting blue light are larger, and the display pixels emitting green light are smaller, but this specification does not limit this. Figure 6 In the first display area 101, the second display area 102 and the third display area 103, the first column (counting from left to right, the same below) display pixels 104 and the second column display pixels 104 are display pixels of different colors.

[0060] Therefore, the length L3 of the side of the first column of display pixels 104 in the third display area 103 parallel to the first direction DR1 is equal to the length L3' of the side of the first column of display pixels 104 in the second display area 102 parallel to the first direction DR1, and the length L4 of the side of the second column of display pixels 104 in the third display area 103 parallel to the first direction DR1 is equal to the length L4' of the side of the first column of display pixels 104 in the second display area 102 parallel to the first direction DR1. Furthermore, the length of the first column of display pixels 104 in the third display area 103 parallel to the second direction DR2 is equal to the length of the first column of display pixels 104 in the second display area 102 parallel to the second direction DR2. The length of the second column of display pixels 104 in the third display area 103 parallel to the second direction DR2 is equal to the length of the second column of display pixels 104 in the second display area 102 parallel to the second direction DR2.

[0061] In this embodiment, the lengths of the same color display pixels 104 in the second display area 102 and the third display area 103 are equal in the first direction DR1 and the second direction DR2, respectively. This helps to reduce the shape difference of the same color display pixels 104 in these two areas, improve the display abruptness caused by the abrupt change in the aperture ratio of the same color display pixels 104, and is particularly beneficial to improve the display difference under a large viewing angle in the preset direction.

[0062] In this embodiment, the shape of the display pixels 104 in the second display area 102, which is composed of strip shapes, can be similar to the shape of the display pixels 104 in the third display area 103, which is beneficial to improving the display consistency between the second display area 102 and the third display area 103. Furthermore, the simple shape of the display pixels 104 in the second display area 102, which is also composed of strip shapes, makes them easy to process and manufacture, thus reducing the difficulty of fabrication.

[0063] Optionally, refer to Figure 4 and Figure 5 The orthographic projection shape of the display pixel 104 located in the second display area 102 onto the substrate 100 includes a symmetrical pattern composed of the first bar pattern and the second bar pattern. The symmetrical pattern includes, but is not limited to, axially symmetrical patterns, centrally symmetrical patterns, and rotationally symmetrical patterns.

[0064] When the orthographic projection of the display pixel 104 located in the second display area 102 onto the substrate 100 is a symmetrical pattern, it is beneficial to maintain the shape similarity with the display pixel in the third display area 103 in multiple directions, reduce the shape difference between the display pixels in the third display area 103 and the second display area 102, and thus improve the display abruptness phenomenon caused by the abrupt change in the aperture ratio of the display pixel.

[0065] In one exemplary embodiment of this specification, reference is still made to... Figures 4-6 , the orthographic projection shape of the display pixels 104 located in the first display area 101 on the substrate 100 includes a circle or an ellipse.

[0066] The orthographic projection shape of the display pixels 104 in the first display area 101 on the substrate 100 is circular or elliptical, which is beneficial to weaken the diffraction effect generated by the gap between the display pixels 104 in the first display area 101 on transmitted light, and meets the parameter requirements for received light of functional devices such as cameras located on a side of the first display area 101 facing away from the light exit direction.

[0067] The display pixels 104 located in the second display area 102 can be in addition to Figure 4 , Figure 5 and Figure 6 the shapes shown, they can also be I-shaped, cross-shaped and other shapes, which are not exhaustively listed herein.

[0068] In an exemplary embodiment of the present specification, still referring to Figures 4-6 , the aperture ratio of the display pixels 104 located in the second display area 102 is equal to the aperture ratio of the display pixels located in the first display area 101.

[0069] In this embodiment, keeping the aperture ratio of the display pixels 104 in the second display area 102 and the first display area 101 the same can make the load of the display pixels 104 in the first display area 101 and the second display area 102 the same, so that the pixel circuits for driving the first display area 101 and the second display area 102 can be the same, which is beneficial to reducing the manufacturing difficulty of the display panel.

[0070] In an exemplary embodiment of the present specification, referring to Figure 7 , the display panel further comprises:

[0071] pixel circuits located on the substrate 100, the pixel circuits comprise first-type pixel circuits 1051 and second-type pixel circuits 1052, the first-type pixel circuits 1051 are distributed in the third display area 103, and the first-type pixel circuits 1051 are electrically connected to at least one display pixel 104 located in the third display area 103.

[0072] the second-type pixel circuits 1052 are distributed in the second display area 102, and the second-type pixel circuits 1052 are electrically connected to at least one display pixel 104 located in the first display area 101 and / or the second display area 102.

[0073] In this embodiment, since the aperture ratios of the display pixels 104 in the first display area 101, the second display area 102, and the third display area 103 are different, two types of pixel circuits are provided on the substrate 100 to drive the display pixels 104 with different loads. Specifically, the first type of pixel circuit 1051 located in the third display area 103 is used to drive the display pixels 104 with a larger aperture ratio, and the second type of pixel circuit 1052 located in the second display area 102 is used to drive the display pixels 104 with a smaller aperture ratio (i.e., the display pixels 104 in the first display area 101 and the second display area 102).

[0074] Since the pixel circuit driving the first display area 101 is placed in the second display area 102 in this embodiment, it is beneficial to improve the light transmittance of the first display area 101.

[0075] exist Figure 7 In this specification, one pixel circuit is connected to one display pixel 104. However, in other embodiments of this specification, one pixel circuit may also be connected to two or more display pixels 104. This specification does not limit this and it depends on the actual situation.

[0076] Exemplary mask template

[0077] This specification also provides a mask template for preparing display pixels. The mask template includes a first mask area, a second mask area, and a third mask area. The second mask area is at least partially surrounded by the outside of the first mask area, and the third mask area is at least partially surrounded by the outside of the second mask area.

[0078] The first mask area, the second mask area, and the third mask area include a plurality of pixel openings. In preparing pixel openings of the same color, the aperture ratio of the pixel openings in the first mask area and the second mask area is less than the aperture ratio of the pixel openings in the third mask area. The length of the pixel openings in the second mask area in a preset direction is less than or equal to the length of the pixel openings in the third mask area in the preset direction.

[0079] Optionally, the preset direction is parallel to the substrate.

[0080] The mask provided in the embodiments of this specification can be a fine metal mask (FMM), that is, a mask used to prepare display pixels of different colors, and in particular, a mask used to prepare the light-emitting layer in display pixels of different colors.

[0081] Specifically, the first mask region, the second mask region, and the third mask region are used to prepare the display pixels in the first display area, the second display area, and the third display area of ​​the exemplary display panel described above, respectively. The design of the pixel openings in the first mask region, the second mask region, and the third mask region can be referred to the relevant description in the exemplary display panel described above, and will not be repeated here.

[0082] Exemplary display module

[0083] This specification also provides an embodiment of a display. Module ,like Figure 8 As shown, it includes: a display panel as described in any of the above embodiments.

[0084] Figure 8 For the display panel A cross-sectional structural diagram, in Figure 8 In addition to the array substrate A100, the display panel also includes a counter substrate A300 located on one side of the light-emitting direction of the array substrate A100. The counter substrate A300 includes a counter substrate 303, a black matrix 302 located on the counter substrate 303, and a transparent color resist 304 located in the area defined by the black matrix 302. In addition, it also includes a protective film layer 301 to isolate water and oxygen from eroding the black matrix 302 and the transparent color resist 304.

[0085] Of course, in some embodiments of this specification, when the display pixel is used to emit monochromatic light (e.g., white light), the transparent color group 304 on the opposing substrate A300 can be replaced with color resist of different colors (e.g., red color resist, green color resist, and blue color resist, etc.), and this specification does not limit this.

[0086] Exemplary electronic devices

[0087] This specification also provides an electronic device, such as... Figure 9 As shown, Figure 9 This is a schematic diagram of the structure of electronic device B100, which includes the display described in any of the above embodiments. Module .

[0088] In summary, the embodiments of this specification provide a display panel, a photomask, a display module, and an electronic device. The display panel includes a first display area, a second display area, and a third display area on a substrate. The first display area has a smaller aperture ratio for its display pixels, meeting the high transmittance requirement of the first display area, making it suitable as a high-transmittance area for mounting functional components such as cameras. Furthermore, a second display area is provided between the first and third display areas for transition. The aperture ratio of the display pixels in the second display area is smaller than that in the third display area, and the length of the display pixels in the second display area in a predetermined direction is less than or equal to the length of the display pixels in the third display area in the predetermined direction. This helps reduce the shape difference of the display pixels in these two areas, improving the display abruptness caused by sudden changes in the aperture ratio of the display pixels, and is particularly beneficial for improving display differences at large viewing angles in the predetermined direction.

[0089] This document describes exemplary embodiments with reference to cross-sectional views and / or plan views, which are idealized exemplary drawings. In the drawings, the thickness of layers and regions is enlarged for clarity. Therefore, variations in shape relative to the drawings are contemplated due to, for example, manufacturing techniques and / or tolerances. Thus, exemplary embodiments should not be construed as limited to the shapes of the regions shown herein, but rather include shape deviations due to, for example, manufacturing processes.
