This increases the distance between the outline of the third sub-pixel on the notch side and the adjacent first sub-pixel block, while decreasing the distance between the outline of the third sub-pixel on the protrusion side and the adjacent second sub-pixel block. This reduces the distance difference between the third sub-pixel and the first sub-pixels on both sides, facilitating the uniform arrangement of the touch electrodes around the third sub-pixel, thereby reducing viewing angle distortion of the display panel and improving its display effect. By providing a protrusion on one side of the third sub-pixel and a notch on the other, the above-mentioned technical effects are achieved while minimizing changes to the overall opening area of ​​the third sub-pixel, thus reducing the impact on the overall pixel arrangement and lowering design costs.

[0043] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0044] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "second", "first", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0045] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0046] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher height than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower height than the second feature.

[0048] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "first," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0049] There are many methods for colorizing OLED display panels. The most mature and mass-produced OLED colorization technology is OLED vapor deposition technology. Specifically, it uses vapor deposition technology to form organic light-emitting devices at corresponding sub-pixel positions on an array substrate through a fine metal mask (FMM). This fine metal mask is often simply referred to as a vapor deposition mask. The key to manufacturing high PPI (Pixels Per Inch) OLED displays lies in the precision and mechanical stability of the FMM and the pixel arrangement.

[0050] Specifically, the FMM (Film Mesh Matrix) should be designed to minimize warping and breakage to avoid defects such as blurring and misalignment of the vapor-deposited film layer, which affect deposition quality. The pixel arrangement is the primary factor determining whether the FMM is prone to warping and breakage. In other words, the sub-pixel arrangement largely determines the mechanical properties of the FMM, which in turn largely determines the deposition quality. For example, if the spacing between two sub-pixels is too small, the connection between the two deposition openings of the corresponding FMM is at risk of breakage, and the alignment space between the FMM and the sub-pixel area will be reduced, potentially leading to color defects or color mixing. Increasing the width of the connection requires reducing the size of the sub-pixels, affecting the aperture ratio of the OLED display and hindering high resolution. Therefore, in current OLED displays, the distance between sub-pixels in the pixel arrangement structure is relatively large, resulting in a smaller aperture area for the sub-pixels at the same resolution. This necessitates increasing the driving current to meet the brightness requirements of the display. However, operating OLEDs under high driving currents can easily lead to device aging, causing large-viewing-angle color shift and shortening the lifespan of the OLED display device. In addition, the lifespan of the three colors of subpixels is different due to the different materials used. In particular, the lifespan of the blue pixels is significantly shorter than that of the other two colors, and they are prone to "burn-in" problems after a period of use.

[0051] Meanwhile, to enable more functions in terminal devices, under-display photosensitive devices are becoming increasingly common, such as fingerprint recognition devices. The photosensitive device for acquiring fingerprint images can include an optical sensor, which may contain multiple pixels. These pixels can receive light signals reflected from different locations on an object and convert the incident light into electrical signals, thereby generating an image of the object. Therefore, the amount of light received by each pixel and its contrast both affect the quality of the generated image. This also places certain requirements on the light transmittance of the display panel, further increasing the difficulty of designing the pixel arrangement structure.

[0052] To address the aforementioned problems, this application provides a detailed description of the display panel and display device according to the accompanying drawings. In the drawings, the x-direction is a first direction, and the y-direction is a second direction. For ease of drawing, the dimensions in the drawings are not necessarily proportional to actual dimensions.

[0053] Please see Figures 1 to 4 , Figure 1 This is a top view structural diagram of a display panel provided in an embodiment of this application. Figure 2 An example is shown. Figure 1 The display panel in the image is a magnified view at position A. Figure 3 An example is shown. Figure 2 A magnified view of a portion of the display panel. Figure 4 The spectrum curves for blue light, green light, and blue light are shown.

[0054] like Figures 1 to 4As shown, an embodiment of the first aspect of this application provides a display panel 10, including first sub-pixels 100, second sub-pixels 200, and third sub-pixels 300 of different colors. Two first sub-pixels 100 and two second sub-pixels 200 constitute a first virtual quadrilateral 400. Within the same first virtual quadrilateral, the two first sub-pixels 100 include a first sub-pixel block 110 and a second sub-pixel block 120 spaced apart along a first direction (x-direction in the figure) and located at one diagonal position of the first virtual quadrilateral 400. The two second sub-pixels 200 are spaced apart along a second direction (y-direction in the figure) and located at the other diagonal position of the first virtual quadrilateral 400. One third sub-pixel 300 is located within the first virtual quadrilateral 400, where the first direction x intersects the second direction y. Four third sub-pixels 300 constitute a second virtual quadrilateral 500, with either the first sub-pixels 100 or the second sub-pixels 200 located within the second virtual quadrilateral 500. Each third sub-pixel 300 includes a main body 310 and a protrusion 320. In the first virtual quadrilateral 400, the protrusion 320 is located on the side of the main body 310 facing the second sub-pixel block 120. The main body 310 has a notch 311 on the side facing the first sub-pixel block 110. The distance between the center of the main body 310 and the center of the second sub-pixel block 120 (dimension L2 in the figure) is greater than the distance between the center of the main body 310 and the center of the first sub-pixel block 110 (dimension L1 in the figure).

[0055] The center of the main body 310 can be the geometric center of the graphic or the center of the emission color of a sub-pixel; this is not limited. This embodiment uses the example where the center of the main body 310 is the geometric center of the graphic. The shape of the main body 310 is approximately rectangular, and the notch 311 is formed by a recess inward along one of the virtual edges of the rectangle. The center of the main body 310 is the intersection of its virtual diagonals; therefore, the presence of the notch 311 does not cause the center of the main body 310 to shift.

[0056] Optionally, the center of the main body portion 310 located within the first virtual quadrilateral 400 is offset from the center of the first virtual quadrilateral 400.

[0057] Optionally, the first sub-pixel 100 emits red light, the second sub-pixel 200 emits blue light, and the third sub-pixel 300 emits green light. The first sub-pixel 100, the second sub-pixel 200, and the third sub-pixel 300 together constitute a pixel that emits white light. Of course, in some other embodiments, the first sub-pixel 100, the second sub-pixel 200, and the third sub-pixel 300 can also be colors other than red, green, and blue; this is not limited to these specific colors.

[0058] It should be understood that different colors of light have different wavelengths. A higher wavelength means higher light energy. High-energy light easily causes the decay of organic light-emitting materials, making sub-pixels that emit high-energy photons more prone to decay. Figure 3 In the spectral curve shown, the horizontal axis represents wavelength in nanometers, and the vertical axis represents light intensity. Since blue light has a shorter wavelength than red and green light, it has higher energy. Organic light-emitting materials that emit blue light are more prone to decay, causing the light emitted from pixel units to tend to be reddish, resulting in a white light color shift. Furthermore, the light emitted by each sub-pixel undergoes repeated reflection and re-reflection between the anode and cathode through the microcavity effect, resulting in amplification and constructive interference. This increases the brightness of the light and further amplifies the color shift.

[0059] Optionally, as a preferred implementation, such as Figure 3 As shown, the light-emitting area (pixel aperture area) of the blue sub-pixel (second sub-pixel 200) is larger than that of the red sub-pixel (first sub-pixel 100) and the green sub-pixel (third sub-pixel 300). This can, to some extent, reduce display defects caused by the different decay rates of organic light-emitting materials emitting different colors of light. It should be noted that, since the human eye is more sensitive to green light, in some embodiments, the light-emitting area of ​​the green sub-pixel can be smaller than that of the red sub-pixel. Of course, in other embodiments, the light-emitting area of ​​the green sub-pixel can be equal to that of the red sub-pixel; this is not limited here.

[0060] Optionally, the first virtual quadrilateral 400 has a first virtual side 410 and a second virtual side 420 that are opposite and parallel to each other. The length of the first virtual side 410 is less than the length of the second virtual side 420. The first sub-pixel block 110 is located on the first virtual side 410, and the second sub-pixel block 120 is located on the second virtual side 420.

[0061] The display panel 10 provided in this application offsets the center of the main body 310 from the center of the first virtual quadrilateral 400, and the distance L2 between the center of the main body 310 and the center of the second sub-pixel block 120 is greater than the distance L1 between the center of the main body 310 and the center of the first sub-pixel block 110. Thus, under the same process conditions, this sub-pixel arrangement structure increases the spacing between the third sub-pixels 300 in two adjacent first virtual quadrilaterals 400 sharing the first virtual edge 410 compared to other arrangement forms. This expands the usable distance between adjacent pixel openings, which is beneficial for the transmission of tension force, reduces mask deformation, and lowers the difficulty of fine metal mask manufacturing and vapor deposition processes. Simultaneously, this design, by increasing the area of ​​the blue and red sub-pixels and having the green sub-pixels share the red and blue sub-pixels, reduces the probability of "burn-in" problems caused by the different lifespans of the three color sub-pixels, extending the lifespan of the display panel 10. By including a main body 310 and a protrusion 320 on the side of the main body 310 facing the second sub-pixel block 120, and providing a notch 311 on the side of the main body 310 facing the first sub-pixel block 110, the distance between the third sub-pixel 300 and the adjacent first sub-pixel block 110 on the side of the notch 311 is increased, while the distance between the third sub-pixel 300 and the adjacent second sub-pixel block 120 on the side of the protrusion 320 is decreased. This reduces the distance difference between the third sub-pixel 300 and the first sub-pixels 100 on both sides, which is beneficial for the uniform arrangement of the touch electrodes around the third sub-pixel 300, thereby reducing the viewing angle distortion of the display panel 10 and improving the display effect of the display panel 10. By providing a protrusion 320 on one side of the third sub-pixel 300 and a notch 311 on the other side, the above-mentioned technical effects are achieved while minimizing the change in the overall opening area of ​​the third sub-pixel 300, thereby reducing the impact on the overall pixel arrangement and reducing design costs.

[0062] In some embodiments, the first virtual quadrilateral 400 is an isosceles trapezoid, and the first virtual quadrilateral 400 also has two third virtual sides 430 connecting the first virtual side 410 and the second virtual side 420.

[0063] Optionally, in the first virtual quadrilateral 400, one of the two opposing interior angles is less than 90°, and the other is greater than 90°. Specifically, the interior angle of the first virtual quadrilateral 400 corresponding to the first sub-pixel block 110 located on the first virtual edge 410 is greater than 90°, and the interior angle of the first virtual quadrilateral 400 corresponding to the first sub-pixel block 110 located on the second virtual edge 420 is less than 90°. It is worth emphasizing that if the difference between the first virtual edge 410 and the second virtual edge 420 within the first virtual quadrilateral 400 is too large, it will cause an excessive difference in the opposing interior angles of the first virtual quadrilateral 400, resulting in an overly sparse pixel array composed of the first virtual quadrilateral 400, affecting the aperture ratio of the sub-pixels. As a preferred embodiment, the length ratio of the first virtual edge 410 and the second virtual edge 420 within the first virtual quadrilateral 400 can be 0.5-0.95. This prevents the first virtual quadrilateral 400 from being too sparse on the one hand, and makes the sub-pixel arrangement as compact as possible while meeting process limits on the other hand.

[0064] Optionally, in order to ensure that each sub-pixel is evenly distributed as much as possible, in a preferred embodiment, the center of the first sub-pixel 100 and the center of the second sub-pixel 200 coincide with the vertex of the first virtual quadrilateral 400.

[0065] Optionally, multiple first virtual quadrilaterals 400 are arranged in an array by sharing sides. That is, two adjacent pixel groups share the first sub-pixel 100 and the second sub-pixel 200 located on the parallel sides of adjacent first virtual quadrilaterals 400. For example, in a specific array, multiple first virtual quadrilaterals 400 in the Nth row and multiple first virtual quadrilaterals 400 in the N+1th row are interlocked with each other, and the arrangement of the first virtual quadrilaterals 400 in the Nth row is the same as the arrangement of the first virtual quadrilaterals 400 in the N+2th row, where N≥1. In this way, during display, any two adjacent first sub-pixels 100 and second sub-pixels 200 can form a light-emitting pixel with their adjacent third sub-pixel 300. The pixels achieve a high-resolution display effect from a low physical resolution through the principle of color borrowing.

[0066] In some embodiments, the main body 310 includes a first arcuate edge 312 that encloses and forms a notch 311, and the protrusion 320 includes a second arcuate edge 321. In the first virtual quadrilateral 400, the second arcuate edge 321 is located on the side of the third sub-pixel 300 facing the second sub-pixel block 120, and the first arcuate edge 312 is located on the side of the third sub-pixel 300 facing the first sub-pixel block 110.

[0067] The gap 311 is partially enclosed by the first circular arc edge 312.

[0068] Optionally, the circle containing the first arc edge 312 is a virtual circle, and the circle containing the second arc edge 321 is a virtual circle.

[0069] Optionally, the distance from the outline of the first sub-pixel block 110 to the midpoint of the first arc edge 312 is D1, and the distance from the outline of the second sub-pixel block 120 to the second arc edge 321 is D2, where L2-L1 > D2-D1. The midpoint of the first arc edge 312 refers to the point on the first arc edge 312 closest to the center of the main body 310, and the midpoint of the second arc edge 321 refers to the point on the second arc edge 321 farthest from the center of the main body 310.

[0070] Optional, D2=D1.

[0071] The display panel 10 provided in this application makes the distance between the outline of the first sub-pixel block 110 and the midpoint of the first arc edge 312 D1, and the distance between the outline of the second sub-pixel block 120 and the second arc edge 321 D2, and D2=D1, so that the outline spacing between the third sub-pixel 300 and the first sub-pixels 100 on both sides is equal. This is beneficial to the uniform arrangement of the touch electrodes around the third sub-pixel 300, thereby reducing the viewing angle of the display panel 10 and improving the display effect of the display panel 10.

[0072] In some embodiments, the main body 310 further includes two first sides 313 spaced apart along the second direction y, the first sides 313 connecting a first arc side 312 and a second arc side 321. The center of the main body 310 also coincides with the midpoint of the line connecting the midpoints of the two first sides 313.

[0073] Optionally, the first side 313 extends along the first direction x.

[0074] Optionally, the main body 310 may also include a first rounded corner edge 314 and a second rounded corner edge 315, wherein the first rounded corner edge 314 connects the first arc edge 312 and the first side 313, and the second rounded corner edge 315 connects the second arc edge 321 and the first side 313.

[0075] Optionally, the radius of the virtual circle containing the first rounded side 314 is equal to the radius of the virtual circle containing the second rounded side 315.

[0076] Optionally, the first sub-pixel 100 and the second sub-pixel 200 are both rectangles with rounded corners, and the radii of the rounded corners of the first sub-pixel 100 and the second sub-pixel 200 are equal to the radius of the virtual circle where the first rounded corner side 314 is located.

[0077] Optionally, in order to ensure that each sub-pixel is evenly distributed as much as possible, the distance between the two first sides 313 on both sides of the main body 310 in the second direction y and the two adjacent second sub-pixels 200 is equal.

[0078] The display panel 10 provided in this application further includes a first rounded corner edge 314 and a second rounded corner edge 315 in the main body 310. The first rounded corner edge 314 connects the first arc edge 312 and the first edge 313, and the second rounded corner edge 315 connects the second arc edge 321 and the first edge 313. This makes the light-emitting boundary of the third sub-pixel 300 relatively smooth and without sharp corners, which helps to reduce diffraction. By making the diameter of the first arc edge 312 equal to the rounded corner radius of the first sub-pixel 100 and the rounded corner radius of the second sub-pixel 200, the workload of process design is reduced, and there is no need to completely redesign the existing mask. Some parameters of the existing mask can be used to reduce the design workload of the mask, thereby reducing the design cost and cycle.

[0079] In some alternative embodiments, the second virtual quadrilateral 500 is an isosceles trapezoid.

[0080] In this design, the centers of the main bodies 310 of the four third sub-pixels 300 coincide with the four vertices of the second virtual quadrilateral 500. The second virtual quadrilateral 500 has a fourth virtual edge 510 and a fifth virtual edge 520 arranged parallel to each other at intervals. This allows the center lines connecting the third sub-pixels 300 in the same row or column to lie on the same straight line, further reducing the difficulty of wiring and mask fabrication. For example, in the first virtual quadrilateral 400, the first virtual edge 410 is parallel to the second virtual edge 420; in the second virtual quadrilateral 500, the fourth virtual edge 510 is parallel to the fifth virtual edge 520, and the extending directions of the fourth virtual edge 510 and the fifth virtual edge 520 are perpendicular to the extending directions of the first virtual edge 410 and the second virtual edge 420. This further makes the sub-pixel arrangement more uniform and regular, which is beneficial for improving display uniformity and reducing the difficulty of mask fabrication.

[0081] Multiple second virtual quadrilaterals 500 are arranged in an array by sharing sides, and the array arrangement can be referred to the above description of the arrangement of the first virtual quadrilaterals 400.

[0082] The first virtual quadrilateral 400 and the second virtual quadrilateral 500 mentioned above are both arranged in isosceles trapezoidal pixel configurations, which can be called a double-tripod arrangement. Correspondingly, a pixel configuration where the first virtual quadrilateral 400 is an isosceles trapezoid and the second virtual quadrilateral 500 is a rectangle is called a single-tripod arrangement. Both arrangements offer advantages such as clearer details, sharper lines, text, and numbers, and ultra-high visual pixel density. They also increase process margins, which is beneficial for process control and improving product yield in manufacturing. Furthermore, when used in under-display cameras, these two pixel arrangements help improve the transmittance of the sub-screen area, thereby improving the image quality of the front-facing camera. However, compared to a single-tripod arrangement, the double-tripod arrangement achieves superior display quality with lower power consumption, while the single-tripod arrangement is relatively worse in terms of power consumption control.

[0083] Please refer to Figure 1 , Figure 2 and Figure 5 , Figure 5 Another example is shown Figure 1 The display panel in the image is a magnified view at position A.

[0084] like Figure 1 , Figure 2 and Figure 5 As shown, in some alternative embodiments, the area of ​​the protrusion 320 is equal to the area of ​​the notch 311.

[0085] Optionally, the shape of the protrusion 320 is the same as the shape of the notch 311.

Wherein, when the shape of the protrusion 320 is a polygon, the polygon is preferably a triangle.

[0087] The display panel 10 provided in this application makes the area of ​​the protrusion 320 equal to the area of ​​the notch 311, so that the overall opening area of ​​the improved third sub-pixel 300 remains unchanged compared with that before the improvement, thereby reducing the impact on the overall pixel arrangement and reducing design costs.

[0088] In some embodiments, the display panel 10 provided in this application can be an organic light-emitting display panel 10. In the thickness direction, each sub-pixel includes at least an anode and a cathode, and a light-emitting layer located between the anode and the cathode. The driving circuit applies a voltage between the anode and the cathode to excite carrier migration, which acts on the light-emitting layer, thereby emitting light. Specifically, the light-emitting layer includes at least a hole transport layer, an organic material layer, and an electron transport layer. The anode is an electrode used to provide holes or transport holes to the hole transport layer, and the cathode is used to provide electrons or transport electrons to the organic material layer.

[0090] Optionally, the display panel 10 includes a display area AA and a non-display area NA that at least partially surrounds the display area AA, with each sub-pixel located within the display area AA. This embodiment illustrates an example where the non-display area NA completely surrounds the display area AA.

[0091] Optionally, the display panel 10 may also include a pixel definition layer, which includes a pixel defining portion and a plurality of pixel openings formed by the pixel defining portion. The light-emitting layer of each sub-pixel is disposed in the pixel opening to avoid cross-coloring or interference between adjacent sub-pixels.

[0092] Optionally, in the thickness direction, a substrate for supporting the layer structure is provided on the same side of each sub-pixel. The substrate can be configured in various ways, including a substrate and a first conductive layer, a second conductive layer, and a third conductive layer stacked on one side of the substrate.

As an example, the gate and the first electrode can be located in the first conductive layer, the second electrode can be located in the second conductive layer, and the source and drain can be located in the third conductive layer.

[0093] Optionally, an encapsulation layer is further provided on the side of each sub-pixel facing away from the substrate in the thickness direction. The encapsulation layer includes a first encapsulation layer, which is made of inorganic materials; that is, the first encapsulation layer is an inorganic encapsulation layer. The inorganic encapsulation layer can be prepared using a chemical vapor deposition method, which can improve the density of the first encapsulation layer, thereby improving the encapsulation effect.

[0094] Optionally, the encapsulation layer further includes a second encapsulation layer located on the side of the first encapsulation layer facing away from the substrate. The material of the second encapsulation layer includes organic materials. That is, the second encapsulation layer is an organic encapsulation layer, which can be prepared by inkjet printing, allowing the encapsulation layer to have a suitable thickness.

[0095] Optionally, the encapsulation layer also includes a third encapsulation layer located on the side of the second encapsulation layer facing away from the substrate. The material of the third encapsulation layer includes inorganic materials. That is, the third encapsulation layer is an inorganic encapsulation layer. Adding an inorganic encapsulation layer outside the organic encapsulation layer can further improve the encapsulation effect.

[0096] Optionally, the first encapsulation layer and the third encapsulation layer are made of the same material. This allows the first and third encapsulation layers to be fabricated using the same equipment, simplifying the fabrication process of the display panel 10.

[0097] The second aspect of this application also provides a display device including the display panel 10 of any of the first aspect embodiments described above. Since the display device provided in the second aspect of this application includes the display panel 10 of any of the above embodiments, it possesses the beneficial effects of the display panel 10 of any of the above embodiments, which will not be elaborated further here.
