Description

Technical Field

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

[0002] Currently, display technology has permeated every aspect of our daily lives, and accordingly, an increasing number of materials and technologies are being used in display screens. Display panels, as an important component of display devices, are used to implement the display functions of display devices. Currently, the mainstream display screens include liquid crystal display panels and organic light-emitting diode (OLED) panels.

[0003] Liquid crystal display panels are widely used in various fields due to their advantages such as thinness, low power consumption, and low radiation. Organic light-emitting diodes, as current-type light-emitting devices, are increasingly being used in high-performance displays. OLED display panels offer many excellent features, including self-luminescence, wide viewing angles, fast response times, high contrast, a wide color gamut, low energy consumption, thin panels, rich colors, flexible displays, and a wide operating temperature range. Therefore, they are hailed as the next generation of flat panel display technology.

[0004] The sub-pixels in liquid crystal display panels are usually arranged in a standard RGB array, with a small spacing between adjacent sub-pixels, which can achieve a high image resolution (Pixels Per Inch, PPI) design, which is relatively perfect. For organic light-emitting display panels, since the sub-pixels of each color of the organic light-emitting display panel have different lifespans, the sub-pixels of each color usually need to be designed to be different sizes. In addition, since the opening size of the high-precision metal mask directly determines the size of the sub-pixel, the high-precision metal mask has limitations in the preparation process. Usually, the sub-pixels of each color are designed to be relatively symmetrical structures such as circles. Furthermore, in order to achieve uniform color mixing, the sub-pixels of each color are designed to share a special pixel arrangement using a common algorithm. Therefore, it is difficult to make a standard RGB matrix arrangement. Instead, special pixel arrangement structures such as delta arrangement and 2in1 arrangement are adopted. However, these special pixel arrangement structures inevitably lead to a small aperture ratio, that is, the pixel definition layer is not fully utilized, wasting the space of the display panel, and it is difficult to achieve high image resolution.

[0005] Therefore, there is an urgent need to provide a display panel and a display device that can improve image resolution. Summary of the Invention

[0006] In view of this, the present invention provides a display panel and a display device to improve image resolution.

[0007] In one aspect, the present invention provides a display panel, comprising:

[0008] substrate;

[0009] A pixel unit located on one side of the substrate, the pixel unit including a first sub-pixel, a second sub-pixel and a third sub-pixel, wherein the second sub-pixel and the third sub-pixel surround the first sub-pixel, at least one of the second sub-pixel and the third sub-pixel is an L-shaped structure, and at least part of the first sub-pixel is located in a semi-enclosed space of the L-shaped structure.

[0010] In another aspect, the present invention provides a display device comprising the above-mentioned display panel.

[0011] Compared with the prior art, the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0012] In the display panel of the present invention, the second and third subpixels surround the first subpixel, and at least one of the second and third subpixels has an L-shaped structure. At least a portion of the first subpixel is located within the semi-enclosed space of the L-shaped structure. The first subpixel is disposed in the space between the second and third subpixels. This reduces space waste in non-opening locations, maximizes the subpixel opening area, and helps improve the space utilization and image resolution of the display panel. Even while maintaining the same image resolution, the subpixel opening area can be increased, thereby improving the subpixel aperture ratio, extending the subpixel lifespan, and enhancing the stability of the display panel.

[0013] Of course, any product implementing the present invention does not necessarily need to achieve all of the technical effects described above at the same time.

[0038] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0039] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0040] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0041] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0042] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0043] In view of the fact that the pixel arrangement structure in the related art inevitably leads to a small aperture ratio, the pixel definition layer is not fully utilized, the space of the display panel is wasted, and it is difficult to achieve high image resolution, the inventors have conducted the following research on the related art, referring to Figure 1 、 Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of a planar structure of a display panel provided by related technology. Figure 2 This is another schematic diagram of the planar structure of a display panel provided by the related art. Figure 3 This is a schematic diagram of a pixel arrangement provided by related technology. Figure 1 、 Figure 2 and Figure 3 The pixel arrangement in FIG is a common arrangement in related technologies. Figure 1The three sub-pixels in the pixel repeating unit 010 form a pixel repeating unit 010, and the pixel repeating unit 010 includes a first sub-pixel 001, a second sub-pixel 002, and a third sub-pixel 003. The openings of the first sub-pixel 001, the second sub-pixel 002, and the third sub-pixel 003 are circular. The lines connecting the centers of the first sub-pixel 001, the second sub-pixel 002, and the third sub-pixel 003 in the same pixel repeating unit 010 form a triangle. The arrangement positions of the first sub-pixel 001, the second sub-pixel 002, and the third sub-pixel 003 in the two pixel repeating units 010 in the column direction Y are different. Figure 1 It can be seen that the area K1 between adjacent sub-pixels causes space waste. The area K1 has a large space, but no sub-pixels are set, so Figure 1 The pixel arrangement cannot achieve high image resolution. Figure 2 The four sub-pixels in the pixel repeating unit 010 are a first sub-pixel 001, a second sub-pixel 002 and two third sub-pixels 003. The openings of the first sub-pixel 001, the second sub-pixel 002 and the third sub-pixel 003 are circular. The area K2 between the first sub-pixel 001 and the second sub-pixel 002 and between the two third sub-pixels 003 causes space waste. The area K2 has a large space, but no sub-pixels are set, so Figure 2 The pixel arrangement cannot achieve high image resolution. Figure 3 This is an enlarged view of the pixel arrangement. Figure 3 Taking the Pentile arrangement as an example, assuming that the width of the second sub-pixel 002 in the row direction X is 10 μm, the redundant length of the sub-pixel during deposition is 10 μm (the length of the non-opening area), and the sub-pixel length is 40 μm. Figure 3 As shown, the area of ​​the hollow area K3 surrounded by the three sub-pixels is approximately equal to the area of ​​a triangle with a base length and a height length of 10 μm, which is 50 μm. 2 ; The effective area of ​​a single sub-pixel is approximately: 10×40=400um 2 Therefore, the effective area wasted in a pixel unit is approximately: 50 / (400×3)=4.2%. In short, the pixel arrangement methods in the related art will cause space waste and it is difficult to achieve high resolution.

[0044] In view of this, the present invention provides a display panel and a display device to achieve high image resolution of the display panel. Specific embodiments of the display panel and the display device will be described in detail below.

[0045] Reference Figure 4 、 Figure 5 、 Figure 6 and Figure 7 , Figure 4is a schematic diagram of a planar structure of a display panel provided by the present invention, Figure 5 yes Figure 4 A cross-section view in the A-A' direction, Figure 6 is a schematic diagram of a planar structure of another display panel provided by the present invention. Figure 7 This is a schematic diagram of a planar structure of another display panel provided by the present invention. The display panel 100 provided in this embodiment includes: a base substrate 1001; a pixel unit 2000 located on one side of the base substrate 1001; the pixel unit 2000 includes a first sub-pixel 2001, a second sub-pixel 2002, and a third sub-pixel 2003. The second sub-pixel 2002 and the third sub-pixel 2003 surround the first sub-pixel 2001; at least one of the second sub-pixel 2002 and the third sub-pixel 2003 is in an L-shaped structure; and at least a portion of the first sub-pixel 2001 is located within a semi-enclosed space 3000 of the L-shaped structure.

[0046] Specifically, Figure 5 A schematic diagram of a film layer of a display panel is shown. Optionally, the display panel 100 provided in this embodiment can be a display panel using organic light-emitting diode display technology, that is, an OLED (Organic Light-Emitting Diode) display panel. Optionally, from the perspective of the film layer structure, the display panel 100 includes a base substrate 1001, an array layer 10, a light-emitting layer 20, and an encapsulation layer 30. The basic structure of the light-emitting layer 20 of the OLED display panel 100 generally includes an anode 201, a light-emitting material layer 202, and a cathode 203. When the power supply supplies an appropriate voltage, the data line DL01 drives the data voltage through the transistor T0 to drive the anode 201. The holes in the anode 201 and the electrons in the cathode 203 combine in the light-emitting material layer 202 to generate bright light. Figure 5 The insulating layer, the pixel definition layer 21, and the encapsulation layer 30 are not pattern-filled. Figure 4 The data line DL01 is not shown in the plan view. Figure 5 Data line DL01 is shown in FIG. Compared to thin-film field-effect transistor liquid crystal displays (TFT-LCDs), OLED displays offer high visibility and brightness, are more energy-efficient, lightweight, and thin. Of course, in other embodiments of the present invention, the display panel 100 may also utilize inorganic light-emitting diode display technology, such as a micro-LED display panel or a mini-LED display panel.

[0047] For an OLED display panel, each sub-pixel has an opening A1. The opening A1 mentioned in the present invention can be regarded as, for example, Figure 5 The area defined by the pixel definition layer 21 for accommodating the light-emitting material layer 202 , the non-opening A2 can be regarded as other areas in the display area AA except the opening A1 . Figure 4The portion filled with the pattern in the first sub-pixel 2001 refers to the opening A1 of the first sub-pixel 2001. Similarly, the portion filled with the pattern in the second sub-pixel 2002 refers to the opening A1 of the second sub-pixel 2002. The portion filled with the pattern in the third sub-pixel 2003 refers to the opening A1 of the third sub-pixel 2003. These details will not be repeated here. The size of the openings in the first sub-pixel 2001, the second sub-pixel 2002, and the third sub-pixel 2003 is not specifically limited and can be adjusted based on the actual lifespan of the luminescent material.

[0048] Figure 4 、 Figure 6 and Figure 7 The display panel 100 has a display area AA and a non-display area BB surrounding the display area AA. Of course, the non-display area BB can also semi-surround the display area AA, such as a water drop screen, which is not specifically limited here. Figure 4 、 Figure 6 and Figure 7 The pixel units 2000 are arranged in an array. Of course, the number of pixel units 2000 is only for schematic illustration and is not intended to limit the number of pixel units 2000 in an actual product.

[0049] Optionally, the first sub-pixel 2001 is located in the middle of the pixel unit 2000, and the second sub-pixel 2002 and the third sub-pixel 2003 are arranged around the first sub-pixel 2001. Figure 4 Taking the third sub-pixel 2003 as an L-shaped structure and the second sub-pixel 2002 as an L-shaped structure as an example, the L-shaped structure of the third sub-pixel 2003 has a semi-enclosed space 3000, and the second sub-pixel 2002 also has the same semi-enclosed space 3000. The first sub-pixel 2001 is located in the semi-enclosed space 3000, and the first sub-pixel 2001 is set in the space between the second sub-pixel 2002 and the third sub-pixel 2003. There is less waste of space at the position without the opening A2, and the area of ​​the opening A1 of the sub-pixel is maximized, which is beneficial to improving the space utilization of the display panel 100 and improving the image resolution of the display panel 100. Figure 6 In the example, the third sub-pixel 2003 is an L-shaped structure and the second sub-pixel 2002 is a rectangle. Figure 6 Similarly, the second sub-pixel 2002 and the third sub-pixel 2003 are arranged around the first sub-pixel 2001, and the first sub-pixel 2001 is located in the semi-enclosed space 3000 formed by the L-shaped structure of the third sub-pixel 2003. The first sub-pixel 2001 is arranged in the space between the second sub-pixel 2002 and the third sub-pixel 2003. There is less waste of space at the position where the non-opening A2 is located, and the area of ​​the opening A1 of the sub-pixel is maximized, which is beneficial to improving the space utilization of the display panel 100 and improving the image resolution of the display panel 100. Figure 7In the figure, the second sub-pixel 2002 has an L-shaped structure and the third sub-pixel 2003 has a rectangular shape. The first sub-pixel 2001 is located in the semi-enclosed space 3000 formed by the L-shaped structure of the second sub-pixel 2002. The first sub-pixel 2001 is arranged in the space between the second sub-pixel 2002 and the third sub-pixel 2003. This reduces the space wasted in the non-opening A2 position and maximizes the area of ​​the sub-pixel opening A1, which is beneficial for improving the space utilization of the display panel 100 and the image resolution of the display panel 100. It should be noted that the first sub-pixel 2001 can also be partially located in the semi-enclosed space 3000, which is not shown in the figure.

[0050] Compared with the related art, the display panel of the present invention has at least the following beneficial effects:

[0051] In the display panel 100 of the present invention, the second subpixel 2002 and the third subpixel 2003 surround the first subpixel 2001. At least one of the second subpixel 2002 and the third subpixel 2003 has an L-shaped structure. At least a portion of the first subpixel 2001 is located within the semi-enclosed space 3000 of the L-shaped structure. The first subpixel 2001 is disposed in the space between the second subpixel 2002 and the third subpixel 2003. This minimizes space waste in locations other than the opening A2, maximizing the area of ​​the subpixel opening A1, thereby improving the space utilization of the display panel 100 and enhancing the image resolution of the display panel 100. Even while maintaining the same image resolution, the area of ​​the subpixel opening A1 can be increased, thereby improving the subpixel aperture ratio. It is understood that the service life of a light-emitting unit in a display panel is positively correlated with its luminous intensity. When the subpixel aperture ratio is increased, the total luminous area increases. Therefore, under the same brightness requirement, the brightness of a single subpixel can be reduced to meet the brightness requirement, thereby slowing the degradation of the subpixel's lifespan, improving the subpixel's service life, and enhancing the stability of the display panel.

[0052] In some optional embodiments, referring to Figure 8 、 Figure 9 and Figure 10 , Figure 8 is a schematic diagram of a planar structure of another display panel provided by the present invention. Figure 9 yes Figure 8 A local enlarged view of a pixel unit in Figure 10 yes Figure 6In a partially enlarged view of a pixel unit, the distance between the opposite sides of the first sub-pixel 2001 and the second sub-pixel 2002 is a first distance d1, the distance between the opposite sides of the first sub-pixel 2001 and the third sub-pixel 2003 is a second distance d2, and the distance between the opposite sides of the second sub-pixel 2002 and the third sub-pixel 2003 is a third distance d3; the first distance d1 is equal within the preset difference range, the second distance d2 is equal within the preset difference range, and the third distance d3 is equal within the preset difference range; the first distance d1, the second distance d2, and the third distance d3 are equal within the preset difference range, or at least two of the first distance d1, the second distance d2, and the third distance d3 are not equal.

[0053] Figure 8 and Figure 9 In the figure, the second sub-pixel 2002 and the third sub-pixel 2003 are arranged around the first sub-pixel 2001. The second sub-pixel 2002 and the third sub-pixel 2003 are both L-shaped structures with a semi-enclosed space 3000. The first sub-pixel 2001 is located in the semi-enclosed space 3000. Of course, in this embodiment, the side of the third sub-pixel 2003 away from the first sub-pixel 2001 is an L-shaped right angle, which can reduce the wasted space within the periphery of the pixel unit 2000.

[0054] like Figure 9 As shown, the distance between the opposite sides of the first sub-pixel 2001 and the second sub-pixel 2002 is a first distance d1. The opposite sides in the present invention refer to the positions where the two sub-pixels are facing each other. The first distance d1 is equal within a preset difference range. The preset difference range here is only within the allowable error range. The first distance d1 is relative, such as Figure 9 The first distance d11, the first distance d12, the first distance d13, the first distance d14, and the first distance d15 are all equal within the preset difference range, thereby ensuring that the space between the first sub-pixel 2001 and the second sub-pixel 2002 can be maximized and no space is wasted. At the same time, the distance between the opposite sides of the first sub-pixel 2001 and the third sub-pixel 2003 is the second distance d2, and the second distance d2 is equal within the preset difference range. Figure 9 The second distance d21, the second distance d22, and the second distance d23 are all equal within the preset difference range, thereby ensuring that the space between the first sub-pixel 2001 and the third sub-pixel 2003 can be maximized and no space is wasted; of course, the distance between the second sub-pixel 2002 and the third sub-pixel 2003 on the opposite side is the third distance d3, and the third distance d3 is equal within the preset difference range. Figure 9 The third distance d31 and the third distance d32 are equal within a preset difference range, thereby ensuring that the space between the second sub-pixel 2002 and the third sub-pixel 2003 can be maximized and no space is wasted. Figure 10, the distance between the opposite sides of the first sub-pixel 2001 and the second sub-pixel 2002 is a first distance d1. The opposite sides in the present invention refer to the positions where the two sub-pixels are facing each other. The first distance d1 is equal within a preset difference range. The preset difference range here is only within the error allowable range. The first distance d1 is relative, such as Figure 10 The first distance d11 and the first distance d12 are equal within the preset difference range, thereby ensuring that the space between the first sub-pixel 2001 and the second sub-pixel 2002 can be maximized and no space is wasted. At the same time, the distance between the first sub-pixel 2001 and the opposite side of the third sub-pixel 2003 is the second distance d2, and the second distance d2 is equal within the preset difference range. Figure 10 The second distance d21, the second distance d22, and the second distance d23 are all equal within the preset difference range, thereby ensuring that the space between the first sub-pixel 2001 and the third sub-pixel 2003 can be maximized and no space is wasted; of course, the distance between the second sub-pixel 2002 and the third sub-pixel 2003 on the opposite side is the third distance d3, and the third distance d3 is equal within the preset difference range. Figure 10 The third distance d31 and the third distance d32 are equal within a preset difference range, thereby ensuring that the space between the second sub-pixel 2002 and the third sub-pixel 2003 can be maximized and no space is wasted.

[0055] Optionally, the first distance d1 , the second distance d2 , and the third distance d3 are equal within a preset difference range, or at least two of the first distance d1 , the second distance d2 , and the third distance d3 are not equal. Figure 9 The first distance d1, the second distance d2 and the third distance d3 are not equal, Figure 10 The first distance d1, the second distance d2, and the third distance d3 are equal within a preset difference range. In some optional embodiments, the first distance d1 can be equal to the second distance d2 but not equal to the third distance d3; in some optional embodiments, the first distance d1 can be equal to the third distance d3 but not equal to the second distance d2; in some optional embodiments, the second distance d2 can be equal to the third distance d3 but not equal to the first distance d1. Whether the first distance d1, the second distance d2, and the third distance d3 are equal is not specifically limited here, as long as the first distance d1, the second distance d2, and the third distance d3 are equal within the preset difference range, the first distance d1, the second distance d2, and the third distance d3 are equal within the preset difference range.

[0056] In the related art, the spacing between the adjacent (opening) edges of any two sub-pixels in the pixel arrangement design is quite different. The spacing between some adjacent edges is small, and the spacing between some adjacent edges is large. Then, when the minimum spacing meets the luminous conditions, the part with a larger spacing will cause a waste of space. Secondly, in the process of evaporating different sub-pixels, sub-pixels of different colors correspond to corresponding mask plates, and the spacing between adjacent mask plates at different positions is the same. At this time, the spacing between adjacent sub-pixels of different colors at different positions is also the same, which can improve the accuracy of pixel evaporation. Otherwise, if the spacing between adjacent sub-pixels of different colors at different positions is not the same, and at least the minimum distance between adjacent sub-pixels of different colors must be the same as the distance between the corresponding mask plates, then the part with a larger spacing between adjacent sub-pixels of different colors will waste space, and the corresponding pixel opening rate will also be reduced.

[0057] In the present invention, the first distance d1 is equal within a preset difference range, the second distance d2 is equal within a preset difference range, and the third distance d3 is equal within a preset difference range. The spacing between any adjacent positions of two adjacent sub-pixels is equal within the preset difference range, thereby avoiding the problem of space waste, maximizing the utilization of space area, and facilitating improved image resolution. Even under the premise of unchanged image resolution, the area of ​​the sub-pixel opening A1 can be increased, which can improve the sub-pixel aperture ratio. It can be understood that the service life of the light-emitting unit in the display panel is positively correlated with the luminous intensity. When the sub-pixel aperture ratio is increased, the total luminous area increases. Under the premise of the same brightness requirement, the brightness of a single sub-pixel can be reduced to meet the brightness requirement, thereby slowing the life decay rate of the sub-pixel, improving the service life of the sub-pixel, and enhancing the stability of the display panel. Secondly, during the process of evaporating different sub-pixels, the sub-pixels of different colors correspond to corresponding masks. The spacing between adjacent masks at any adjacent positions is the same. In this case, the spacing between adjacent sub-pixels of different colors at any adjacent positions is also the same, which can improve the accuracy of pixel evaporation.

[0058] In some optional embodiments, continue to refer to Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 , and reference Figure 11 and Figure 12 , Figure 11 is a schematic diagram of a planar structure of another display panel provided by the present invention. Figure 12This is a schematic diagram of the planar structure of another display panel provided by the present invention. A second sub-pixel 2002 and a third sub-pixel 2003 are arranged on either side of a first sub-pixel 2001 along a row direction X. Along a column direction Y, the length of the second sub-pixel 2002 is equal to the length of the third sub-pixel 2003, and the row direction X intersects the column direction Y. Alternatively, the length of the second sub-pixel 2002 is smaller than the length of the third sub-pixel 2003; alternatively, the length of the second sub-pixel 2002 is greater than the length of the third sub-pixel 2003.

[0059] Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 11 and Figure 12 The second sub-pixel 2002 and the third sub-pixel 2003 are arranged on both sides of the first sub-pixel 2001 along the row direction X, wherein: Figure 6 、 Figure 11 The length of the second sub-pixel 2002 along the column direction Y is equal to the length of the third sub-pixel 2003. Figure 7 The length of the second sub-pixel 2002 along the column direction Y is less than the length of the third sub-pixel 2003. Figure 4 、 Figure 8 、 Figure 12 The length of the second sub-pixel 2002 along the column direction Y is less than the length of the third sub-pixel 2003. The lengths of the second sub-pixel 2002 and the third sub-pixel 2003 along the column direction Y are not specifically limited.

[0060] It is understandable that Figure 11 The side of the second sub-pixel 2002 away from the first sub-pixel 2001 is an L-shaped right angle, and the side of the third sub-pixel 2003 away from the first sub-pixel 2001 is also an L-shaped right angle. The outer edge of the pixel unit 2000 is a regular straight line segment, which can fully utilize the space in the display panel 100. Figure 12 The second sub-pixel 2002 is a rectangle, and the side of the third sub-pixel 2003 away from the first sub-pixel 2001 is an L-shaped right angle, and the first sub-pixel 2001 and the second sub-pixel 2002 are both located in the semi-enclosed space 3000 of the third sub-pixel 2003. On the one hand, the outer edge of the pixel unit 2000 is a regular straight line segment, which can fully utilize the space in the display panel 100. On the other hand, there is no wasted space between the first sub-pixel 2001 and the second sub-pixel 2002, between the first sub-pixel 2001 and the third sub-pixel 2003, and between the second sub-pixel 2002 and the third sub-pixel 2003, thereby fully utilizing the space in the display panel 100.

[0061] In this embodiment, the second sub-pixel 2002 and the third sub-pixel 2003 are arranged on both sides of the first sub-pixel 2001 along the row direction X. Along the column direction Y, the length of the second sub-pixel 2002 is equal to the length of the third sub-pixel 2003, and the row direction X intersects the column direction Y. Alternatively, the length of the second sub-pixel 2002 is smaller than the length of the third sub-pixel 2003. Alternatively, the length of the second sub-pixel 2002 is larger than the length of the third sub-pixel 2003, and the second sub-pixel 2002 and the third sub-pixel 2003 surround the first sub-pixel 2001. The first sub-pixel 2001 is provided, and the second sub-pixel 2002 and the third sub-pixel 2003 are arranged on both sides of the first sub-pixel 2001 along the row direction X. The second sub-pixel 2002 and / or the third sub-pixel 2003 are L-shaped structures with a semi-enclosed space 3000. The first sub-pixel 2001 is located in the semi-enclosed space 3000. There is less space waste at positions other than the opening A2, and the area of ​​the opening A1 of the sub-pixel is maximized, which is beneficial to improving the space utilization of the display panel 100 and improving the image resolution of the display panel 100.

[0062] In addition, along the column direction Y, the length of the second sub-pixel 2002 is equal to the length of the third sub-pixel 2003, and the row direction X intersects the column direction Y; alternatively, the length of the second sub-pixel 2002 is smaller than the length of the third sub-pixel 2003; alternatively, the length of the second sub-pixel 2002 is larger than the length of the third sub-pixel 2003. These designs can be used to adjust the color deviation at different viewing angles by changing the lengths of the second sub-pixel 2002 and the third sub-pixel 2003 according to actual needs. When the light output of the pixel unit 2000 deviates from the light output color of the third sub-pixel 2003, the length of the second sub-pixel 2002 in the column direction Y can be reduced, and the pixel unit 2000 can be used to adjust the color deviation at different viewing angles. Figure 4 When the light output of the pixel unit 2000 deviates from the light output color of the second sub-pixel 2003, the length of the second sub-pixel 2003 in the column direction Y can be reduced, and the color deviation can be improved by using the arrangement of the embodiment in FIG. Figure 7 The arrangement of the embodiment in the embodiment is used to improve color deviation.

[0063] In some optional embodiments, continue to refer to Figure 4 、 Figure 6 、 Figure 7 、 Figure 11 and reference Figure 13 , Figure 13This is a schematic diagram of a planar structure of another display panel provided by the present invention. In this embodiment, the first sub-pixel 2001 includes at least one first curved edge 20011, the second sub-pixel 2002 includes at least one second curved edge 20021 that matches the first curved edge 20011; the second sub-pixel 2002 also includes a first edge 20022 located on the side of the second curved edge 20021 away from the first sub-pixel 2001, the first edge 20022 being an L-shaped fold line segment, or a curved segment; and / or, the first sub-pixel 2001 also includes a third curved edge 20012, the third sub-pixel 2003 includes a fourth curved edge 20031 that matches the third curved edge 20012; the third sub-pixel 2003 also includes a second edge 20032 located on the side of the fourth curved edge 20031 away from the first sub-pixel 2001, the second edge 20032 being an L-shaped fold line segment, or a curved segment.

At the same time, the first sub-pixel 2001 also includes a third curved edge 20012, and the third sub-pixel 2003 includes a fourth curved edge 20031 matching the third curved edge 20012.

The second sub-pixel 2002 and the third sub-pixel 2003 form an L-shaped structure. The first sub-pixel 2001 is located within the semi-enclosed space 3000 of the L-shaped structure. The first sub-pixel 2001 is disposed in the space between the second sub-pixel 2002 and the third sub-pixel 2003. This reduces space waste at locations other than the opening A2, maximizes the area of ​​the sub-pixel opening A1, and helps improve the space utilization of the display panel 100 and the image resolution of the display panel 100. Furthermore, the sub-pixels typically require a luminescent material layer to be formed by evaporation. Designing the sub-pixel edge (the sub-pixel opening edge) to be curved can reduce the accumulation of luminescent material at right-angled corners and improve the process yield.

The third sub-pixel 2003 also includes a second edge 20032 located on the side of the fourth curved edge 20031 away from the first sub-pixel 2001. The second edge 20032 is an L-shaped broken line segment. In this way, the outer edge of the third sub-pixel 2003 in the pixel unit 2000 is a regular L-shaped broken line segment, which can make full use of the space in the display panel 100.

There is no wasted space between the first subpixel 2001 and the second subpixel 2002. The second subpixel 2002 also includes a first edge 20022 located on the side of the second curved edge 20021 away from the first subpixel 2001. The first edge 20022 is an L-shaped fold line segment. Thus, the outer edge of the second subpixel 2002 in the pixel unit 2000 is a neat L-shaped fold line segment, which fully utilizes the space in the display panel 100. In the related art, 4.2% of the space between two adjacent pixel units is wasted. In this embodiment, the outer edge of the second subpixel 2002 in the pixel unit 2000 is a neat L-shaped fold line segment, which reduces the space wastage between two adjacent pixel units 2000.

[0067] It should be noted that Figure 11 In the column direction Y, the length of the second sub-pixel 2002 is equal to the length of the third sub-pixel 2003.

Edge 20031 eliminates wasted space between the first subpixel 2001 and the third subpixel 2003. The third subpixel 2003 also includes a second edge 20032 located on the side of the fourth curved edge 20031 away from the first subpixel 2001. Second edge 20032 is an L-shaped fold line segment. Thus, the outer edges of the second and third subpixels 2002 and 2003 in the pixel unit 2000 are all neat L-shaped fold line segments. The four corners of the panel can be filled with subpixels with L-shaped fold line segments, allowing for better pixel fit in the four corners of the panel. This fully utilizes the space within the display panel 100, further improving display quality and performance. In related art, 4.2% of space is wasted between adjacent pixel units.

[0070] In some optional embodiments, continue to refer to Figure 6 The first sub-pixel 2001 further includes a fourth edge 20014 , which is a straight line segment and is close to the edge of the pixel unit 2000 .

Therefore, the outer edge of the pixel unit 2000 is a regular rectangle, and the pixel units 2000 are closely arranged. This structural arrangement will not cause waste of space in the display panel 100, and can improve the space utilization rate by 4.2%. At the same time, the 4.2% effective space can be used to design pixels, thereby improving the image resolution of the display panel 100.

[0072] In some optional embodiments, referring to Figure 14 , Figure 141 is a schematic diagram of a planar structure of another display panel provided by the present invention. The display panel 100 includes a display area AA and a non-display area BB at least partially surrounding the display area AA. The edge of the display area AA close to the non-display area BB includes a curved edge 4001 and a straight edge 4002.

[0073] In some pixel units 2000 , the second sub-pixel 2002 is close to the curved edge 4001 , and the first edge 20022 is a curved segment; and / or the third sub-pixel 2003 is close to the curved edge 4001 , and the second edge 20032 is a curved segment;

[0075] Specifically, an R angle is set in the display panel 100. At the position of the R angle, the edge of the display area AA is a curved edge 4001, and other positions are straight edges, such as Figure 14 The top angle at the intersection of the upper middle frame BB1 ​​and the left frame BB3 is an arc angle, the top angle at the intersection of the upper frame BB1 ​​and the right frame BB4 is an arc angle, the top angle at the intersection of the lower frame BB2 and the left frame BB3 is an arc angle, and the top angle at the intersection of the lower frame BB2 and the right frame BB4 is an arc angle. It should be noted that the edge of the display area AA close to the non-display area BB in the present invention is a virtual edge and is not a specific structure in the display panel 100.

[0076] In this embodiment, refer to Figure 14 The upper left corner where the upper frame BB1 ​​and the left frame BB3 meet is the curved edge 4001. In the pixel unit 20001 adjacent to the curved edge 4001, the second sub-pixel 2002a is close to the curved edge 4001, and the first edge 20022 is a curved segment. The lower right corner where the lower frame BB2 and the right frame BB4 meet is the curved edge 4001. In the pixel unit 20004 adjacent to the curved edge 4001, the third sub-pixel 2003a is close to the curved edge 4001, and the second edge 20032 is a curved segment. ; Of course, the upper right corner where the upper frame BB1 ​​and the right frame BB4 intersect is the curved edge 4001. In the pixel unit 20002 adjacent to the curved edge 4001, the third sub-pixel 2003 is close to the curved edge 4001, and the second edge 20032 is a curved segment. The lower left corner where the lower frame BB2 and the left frame BB3 intersect is the curved edge 4001. In the pixel unit 20003 adjacent to the curved edge 4001, the second sub-pixel 2002 is close to the curved edge 4001, and the first edge 20022 is a curved segment.

[0077] at the same time, Figure 14 It is shown in the figure that in a partial pixel unit 2000, the second sub-pixel 2002 is close to the straight edge 4002 (close to the left border BB3 and the upper border BB1), and the first edge 20022 is an L-shaped broken line segment. At the same time, the third sub-pixel 2003 is close to the straight edge 4002 (close to the lower border BB2 and the right border BB4), and the second edge 20032 is an L-shaped broken line segment.

[0078] In some optional embodiments, in some pixel units 2000, the second sub-pixel 2002 is close to the curved edge 4001, and the first edge 20022 is a curved segment, or the third sub-pixel 2003 is close to the curved edge 4001, and the second edge 20032 is a curved segment; in some pixel units 2000, the second sub-pixel 2002 is close to the straight edge 4002, and the first edge 20022 is an L-shaped broken line segment, or the third sub-pixel 2003 is close to the straight edge 4002, and the second edge 20032 is an L-shaped broken line segment, (not shown in the figure). Optionally, the second sub-pixel 2002 close to the straight edge 4002 can be rectangular, or the third sub-pixel 2003 close to the straight edge 4002 can be rectangular, without specific limitation here.

[0079] In this embodiment, sub-pixels adjacent to curved edge 4001 are arranged with curved segments, while sub-pixels adjacent to straight edge 4002 are arranged with L-shaped folded line segments, so that pixel unit 2000 matches the edge of display area AA. In other words, the four corners of the panel can be filled with sub-pixels arranged with L-shaped folded line segments, which allows the pixels to better fit the four corners of the panel, fully utilizing the space within display panel 100, reducing wasted space in display area AA of display panel 100 that is not the opening A2, and improving the image resolution of display panel 100, thereby further enhancing display quality and effects.

[0080] In some optional embodiments, referring to Figure 15 , Figure 152 is a schematic diagram of a planar structure of another display panel provided by the present invention, wherein four adjacent pixel units 2000 constitute a pixel unit group 5000, wherein the pixel units 2000 in the pixel unit group 5000 are respectively a first pixel unit 2000a, a second pixel unit 2000b adjacent to the first pixel unit 2000a along the row direction X, a third pixel unit 2000c adjacent to the second pixel unit 2000b along the column direction Y, and a fourth pixel unit 2000 adjacent to the first pixel unit 2000a along the column direction Y, wherein the shape of the first pixel unit 2000a rotated 90° along the first direction Z1 is the same as that of the second pixel unit 2000b, the shape of the second pixel unit 2000b rotated 90° along the first direction Z1 is the same as that of the third pixel unit 2000c, the shape of the third pixel unit 2000c rotated 90° along the first direction Z1 is the same as that of the fourth pixel unit 2000, and the shape of the fourth pixel unit 2000 rotated 90° along the first direction Z1 is the same as that of the first pixel unit 2000a;

[0081] The first direction Z1 is a clockwise direction or the first direction Z1 is a counterclockwise direction.

[0082] Of course, in some optional embodiments, the sub-pixels adjacent to the curved edge 4001 adopt a curved segment, and the sub-pixels adjacent to the straight edge 4002 adopt an L-shaped broken line segment. The pixel unit 2000 matches the edge of the display area AA, which can fully utilize the display area AA space of the display panel 100, improve the aperture ratio of the display panel 100, reduce the waste of non-opening A2 space in the display area AA of the display panel 100, and improve the image resolution of the display panel 100.

[0083] Specifically, Figure 15 In the embodiment, two adjacent pixel units 2000 in the row direction X and two adjacent pixel units 2000 in the column direction Y constitute a pixel unit group 5000. Figure 15 The first pixel unit 2000a and the second pixel unit 2000b are adjacent to each other in the row direction X, the second pixel unit 2000b is adjacent to the third pixel unit 2000c in the column direction Y, and the first pixel unit 2000a is adjacent to the fourth pixel unit 2000c in the column direction Y. Figure 15In the embodiment, the shape of the first pixel unit 2000a rotated 90° counterclockwise is the same as that of the second pixel unit 2000b, the shape of the second pixel unit 2000b rotated 90° counterclockwise is the same as that of the third pixel unit 2000c, the shape of the third pixel unit 2000c rotated 90° counterclockwise is the same as that of the fourth pixel unit 2000, and the shape of the fourth pixel unit 2000 rotated 90° counterclockwise is the same as that of the first pixel unit 2000a. That is, in this embodiment, the first direction Z1 is taken as the counterclockwise direction. Of course, the first direction Z1 can also be the clockwise direction, which is not shown here.

[0084] Figure 15 In the description, only the second sub-pixel 2002 and the third sub-pixel 2003 are taken as an example, both of which are L-shaped structures. Figure 15 In the column direction, the length of the second sub-pixel 2002 is smaller than the length of the third sub-pixel 2003. Figure 15 The shapes of the second sub-pixel 2002 and the third sub-pixel 2003 are only for schematic illustration. Of course, the shapes of the second sub-pixel 2002 and the third sub-pixel 2003 can be any of the above embodiments, and the shapes of the second sub-pixel 2002 and the third sub-pixel 2003 are not limited here.

[0085] It should be noted that at least one of the second sub-pixel 2002 and the third sub-pixel 2003 in the present invention has an L-shaped structure. This L-shaped structure is not a circular or other symmetrical structure, which can cause color shift at different viewing angles. In this embodiment, the shape of the first pixel unit 2000a rotated 90° along the first direction Z1 is the same as that of the second pixel unit 2000b. The shape of the second pixel unit 2000b rotated 90° along the first direction Z1 is the same as that of the third pixel unit 2000c. The shape of the third pixel unit 2000c rotated 90° along the first direction Z1 is the same as that of the fourth pixel unit 2000. The shape of the fourth pixel unit 2000 rotated 90° along the first direction Z1 is the same as that of the first pixel unit 2000a. This embodiment utilizes a unique pixel arrangement to mitigate color shift when viewing the panel from different angles. By flipping the panel layout to improve edge and center compatibility, the four pixel units 2000 within the pixel unit group 5000 compensate for each other's light output at different angles. Furthermore, spatial symmetry is enhanced to minimize color shift variations at different panel angles, improving display quality. When used in 3D displays, the high-resolution display panel provided by this embodiment prevents color shift issues because the four pixel units 2000 compensate for each other's light output at different angles.

[0086] In some optional embodiments, referring to Figure 16 , Figure 16 yes Figure 4In another cross-sectional view taken along the A-A' line, the pixel unit 2000 includes a light-emitting unit 6000 located on one side of the base substrate 1001, and a color filter layer 7000 located on a side of the light-emitting unit 6000 away from the base substrate 1001. The color filter layer 7000 includes a first color resist 7001, a second color resist 7002, and a third color resist 7003. The first color resist 7001 corresponds to the first sub-pixel 2001, the second color resist 7002 corresponds to the second sub-pixel 2002, and the third color resist 7003 corresponds to the third sub-pixel 2003.

[0087] Optional, Figure 16 The array layer 10 located on one side of the base substrate 1001 is shown in the figure. The array layer 10 includes a driving circuit. A light-emitting unit 6000 is provided on the side of the array layer 10 away from the base substrate 1001. The light-emitting unit 6000 is also shown on the side away from the base substrate 1001. The color filter layer 7000 is provided on the side of the encapsulation layer 30 away from the base substrate 1001. Figure 16The first light-emitting unit 60011, the second light-emitting unit 60022, and the third light-emitting unit 60033 are shown in the figure. The color filter layer 7000 includes a first color resist 7001, a second color resist 7002, and a third color resist 7003. The first color resist 7001 corresponds to the first sub-pixel 2001, the second color resist 7002 corresponds to the second sub-pixel 2002, and the third color resist 7003 corresponds to the third sub-pixel 2003. That is, the orthographic projection of the first color resist 7001 on the plane where the substrate 1001 is located overlaps with the orthographic projection of the first light-emitting unit 6001 on the plane where the substrate 1001 is located, the orthographic projection of the second color resist 7002 on the plane where the substrate 1001 is located overlaps with the orthographic projection of the second light-emitting unit 6002 on the plane where the substrate 1001 is located, and the orthographic projection of the third color resist 7003 on the plane where the substrate 1001 is located overlaps with the orthographic projection of the third light-emitting unit 6003 on the plane where the substrate 1001 is located. The optional light-emitting units 6000 all emit white light. After passing through the color filter layer 7000, the white light emitted by the first light-emitting unit 6001 passes through the first color resistor 7001, and the first sub-pixel 2001 emits light of the first color. The white light emitted by the second light-emitting unit 6002 passes through the second color resistor 7002, and the second sub-pixel 2002 emits light of the second color. The white light emitted by the third light-emitting unit 6003 passes through the third color resistor 7003, and the third sub-pixel 2003 emits light of the third color. In this embodiment, the shape of the first sub-pixel 2001 is limited by the first color resistor 7001 in the color filter layer 7000, the shape of the second sub-pixel 2002 is limited by the second color resistor 7002, and the shape of the third sub-pixel 2003 is limited by the shape of the third color resistor 7003, thereby realizing that the second sub-pixel 2002 and / or the third sub-pixel 2003 are L-shaped structures. Of course, the first sub-pixel 2001, the second sub-pixel 2002 and the third sub-pixel 2003 of any of the above embodiments may also be manufactured in different shapes, which is not specifically limited here.
