[0002] OLED (Organic Light Emitting Diode) has advantages such as being thin and light, having low power consumption, high resolution, wide viewing angle, and wide color gamut, and is welcomed by the market. In the production process of display panels, during the evaporation process of light-emitting materials, when the mask is aligned with the display panel, the pixel evaporation openings of the mask will inevitably cause scratches on the spacer layer. The more scratches there are, the worse the encapsulation effect is, and the greater the probability of failure in high-temperature processes or high-temperature operation, resulting in a decrease in product yield and affecting the display effect.

[0003] Therefore, there is an urgent need for a display panel and display device to solve the above-mentioned technical problems. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present invention and are not intended to limit the present invention. In the present invention, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0031] OLED (Organic Light Emitting Diode) has advantages such as being thin and light, having low power consumption, high resolution, wide viewing angle, and wide color gamut, and is welcomed by the market. In the production process of display panels, during the evaporation process of light-emitting materials, when the mask is aligned with the display panel, the pixel evaporation openings of the mask will inevitably cause scratches on the spacer layer. The more scratches there are, the worse the encapsulation effect is, and the greater the probability of failure in high-temperature processes or high-temperature operation, resulting in a decrease in product yield and affecting the display effect.

[0032] Please see Figures 1 to 10 This invention provides a display panel 100, including a plurality of first pixels 200, a plurality of second pixels 300, and a plurality of third pixels 400;

[0033] The light-emitting area of ​​the first pixel 200 is greater than the light-emitting area of ​​the second pixel 300, and the light-emitting area of ​​the first pixel 200 is greater than the light-emitting area of ​​the third pixel 400.

[0034] The first pixel 200 is located on the four sides of the virtual rectangle 510, and the sides of the virtual rectangle 510 pass through the first pixel 200. The second pixel 300 is located at the four corners of the virtual rectangle 510 and inside the virtual rectangle 510. The line connecting the center of the second pixel 300 located at the center of the virtual rectangle 510 and the center of each of the first pixels 200 divides the virtual rectangle 510 into four virtual quadrilaterals 520. A third pixel 400 is provided in each of the virtual quadrilaterals 520.

[0035] Wherein, the geometric center of the first pixel is located on one side of the edge of the virtual rectangle.

[0036] This invention moves the geometric center of the pixel with the largest luminous area, so that the geometric center of the first pixel is set on one side of the virtual rectangle. Even if the geometric center of the first pixel is not set on the side of the virtual rectangle, the space between adjacent first and second pixels is increased, so that the spacer unit is set in the increased space. When setting or moving the mask, the distance between the pixel evaporation opening of the mask and the spacer unit is increased, reducing the risk of the pixel evaporation opening of the mask scratching the spacer unit, enhancing the packaging effect, improving product yield, and improving the display effect.

[0037] The technical solution of the present invention will now be described in conjunction with specific embodiments.

[0038] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 3 Along the first direction and the second direction, a first pixel 200 can be set between two adjacent second pixels 300. In the same virtual rectangle 510, at least one virtual quadrilateral 520 includes two first type sides 521 and two second type sides 522. The length of the first type side 521 is not equal to the length of the second type side 522.

[0039] By moving the geometric center of the pixel with the largest luminous area, the virtual quadrilateral has first and second type sides of unequal lengths, thereby increasing the space between adjacent first and second pixels. The spacer unit is then placed in the increased space. When setting or moving the mask, the distance between the pixel evaporation opening of the mask and the spacer unit is increased, reducing the risk of scratching the spacer unit by the pixel evaporation opening of the mask, enhancing the encapsulation effect, improving product yield, and improving the display effect.

[0040] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 3 In the same virtual quadrilateral 520, two first-type edges 521 are arranged adjacent to the same second pixel 300, and two second-type edges 522 are arranged adjacent to another second pixel 300.

[0041] The arrangement of two first-type edges adjacent to each other and two second-type edges adjacent to each other facilitates the more regular use of empty spaces, allowing the spacer units to be placed in the increased empty spaces. When setting or moving the mask, the distance between the pixel evaporation opening of the mask and the spacer unit is increased, reducing the risk of scratching the spacer unit by the pixel evaporation opening of the mask, enhancing the encapsulation effect, improving product yield, and improving the display effect.

[0042] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 3The first pixel 200 includes a main body 202 and four corner portions extending outward along the main body. Each corner portion can extend into a second pixel 300 adjacent to the first pixel 200. The four corner portions of the first pixel 200 include at least one first type corner portion 210 and at least one second type corner portion 220. The maximum distance that the first type corner portion 210 extends outward along the main body 202 is less than the maximum distance that the second type corner portion 220 extends outward along the main body 202.

[0043] The first pixel 200, the second pixel 300, and the third pixel 400 emit different colors. The first pixel 200 has the largest emitting area. The display panel 100 includes an array substrate 110, a pixel definition layer 120 located on one side of the array substrate 110, and a spacer layer 130 located on the side of the pixel definition layer 120 away from the array substrate 110. The spacer layer 130 includes a plurality of spacer units 131. The second pixel 300 includes four corners. The spacer unit is disposed between the corner of the first pixel 200 and the corner of the adjacent second pixel 300, which shrinks at least one corner of the pixel with the largest emitting area. When setting or moving the mask, the distance between the pixel evaporation opening of the mask and the spacer layer 130 is increased, reducing the risk of scratching the spacer layer 130, enhancing the encapsulation effect, improving product yield, and improving the display effect.

[0044] The first type of corner 210 is an inward-retracted corner, and the second type of corner 220 is a regular corner. The inward-retracted corner can increase the distance between the corner of the adjacent second pixel 300 and at the same time, it can minimize the loss of light-emitting area. The light-emitting area at the corner is relatively small, so a larger setting space is obtained with a smaller loss of light-emitting area.

[0045] Among them, Figures 1 to 9 In the diagram, the first direction is the X-axis direction, and the second direction is the Y-axis direction. For ease of description and drawing, the geometric center of the first pixel 200 is designated as the first geometric center 201, and the geometric center of the second pixel 300 is designated as the second geometric center 301.

[0046] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 3 The distance between the end of the first type of corner portion 210 and the first intersection point 230 is less than the distance between the end of the second type of corner portion 220 and the first intersection point 230. The first intersection point 230 is the intersection of the line connecting the two corner portions arranged along the first direction and the line connecting the two corner portions arranged along the second direction.

[0047] In some embodiments, the first pixel 200 may emit blue light, the second pixel 300 may emit red light, and the third pixel 400 may emit green light.

[0048] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 3 The first pixel 200 includes two first-type corner portions 210 and two second-type corner portions 220. The design of the first pixel 200 with two first-type corner portions 210 and two second-type corner portions 220 provides good symmetry, which is beneficial for maintaining the symmetry of pixel emission.

[0049] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 3 The first type of corner portion 210 and the second type of corner portion 220 are arranged adjacent to each other. The geometric center of the first pixel 200 after shrinking is the same as the geometric center of the first pixel 200 before shrinking, so it is not necessary to redesign the position of the geometric center of the first pixel 200, thus saving design costs.

[0050] In some embodiments, please refer to Figure 2 , Figure 5 , Figure 8 The first type of corner portion 210 and the second type of corner portion 220 are diagonally arranged. The geometric center of the first pixel 200 moves towards the two second type of corner portions 220, and the virtual quadrilateral 520 becomes a rhombus. Changing the geometric center of the virtual quadrilateral 520, which can be a large pixel including pixels of RGB colors, increases the complexity of the light-emitting center of the display and improves the display sharpness.

[0051] In some embodiments, please refer to Figures 4 to 9 The first pixel 200 includes one first-type corner portion 210 and three second-type corner portions 220; or the first pixel 200 includes three first-type corner portions 210 and one second-type corner portion 220.

[0052] The first pixel 200 employs a different number of first-type corners 210 and second-type corners 220, which can better change the geometric center of the virtual quadrilateral 520, provide more options for inward shrinkage direction, increase the complexity of the light-emitting center of the display, and improve the display precision.

[0053] In some embodiments, please refer to Figure 5 , Figure 8In any of the virtual rectangles 510, the first-type corner portions 210 of the four first pixels 200 all point to the same second pixel 300, or the second-type corner portions 220 of the four first pixels 200 all point to the same second pixel 300.

[0054] Arranging similar corners in a regular manner can improve the uniformity of the light-emitting area of ​​the first pixel 200 around the second pixel 300, which is beneficial for color calibration of a large pixel and improves the display effect.

[0055] In some embodiments, please refer to Figure 2 , Figure 5 , Figure 8 In the same virtual quadrilateral 520, the distance between the geometric center of the first pixel 200 and the geometric center of the second pixel 300 corresponding to the first corner 210 is a first distance L1, and the distance between the geometric center of the first pixel 200 and the geometric center of the second pixel 300 corresponding to the second corner 220 is a second distance L2; wherein, the first distance L1 is greater than the second distance L2.

[0056] The distance from the geometric center of the first pixel 200 to the first corner 210 is equal to the distance to the second corner 220. The first distance L1 is greater than the second distance L2, indicating that the distance between the first corner 210 and the corner of the adjacent second pixel 300 is greater than the distance between the second corner 220 and the corner of the adjacent second pixel 300. This provides more space around the first corner 210 to accommodate the spacer unit 131. When setting the mask, this increases the distance between the pixel evaporation opening of the mask and the spacer layer 130, reducing the risk of scratching the spacer layer 130, enhancing the encapsulation effect, improving product yield, and improving the display effect.

[0057] In some embodiments, the length of the first type edge 521 is greater than the length of the second type edge 522, and the orthographic projection of the first type edge 521 on the pixel definition layer 120 passes through the orthographic projection of at least one of the spacer units 131 on the pixel definition layer 120.

[0058] The length of the first type of edge 521 corresponds to the first distance L1, and the length of the second type of edge 522 corresponds to the second distance L2. The spacer unit 131 is disposed in the empty space corresponding to the long side. For spacer units 131 of the same size, it is disposed in the empty space corresponding to the short side. When setting the mask, the distance between the pixel evaporation opening of the mask and the spacer unit 131 is increased, which reduces the risk of scratching the spacer unit 131, enhances the packaging effect, improves the product yield, and improves the display effect.

[0059] In some embodiments, the edge of the virtual rectangle 510 passes through the geometric center of the first pixel 200. After the corners of the first pixel 200 are shrunk, the position of the geometric center of the first pixel 200 is redesigned, and the edge of the virtual rectangle 510 passes through the geometric center of the first pixel 200. The arrangement of the geometric centers of the first pixel 200, the second pixel 300, and the third pixel 400 is more regular, which facilitates the design of the circuit and the design of the light-emitting points, and is conducive to the standardized design of the geometric centers.

[0060] In some embodiments, please refer to Figure 2 , Figure 5 , Figure 8 In a virtual rectangle 510, the line connecting the geometric centers of the two first pixels 200 corresponding to two opposite sides of the virtual rectangle 510 passes through the geometric center of the second pixel 300 at the center of the virtual rectangle 510. This can make the light emission centers of the first pixel 200 and the second pixel 300 more regular, improving the regularity of the light emission display.

[0061] In some embodiments, within the same virtual rectangle 510, the geometric centers of the four first pixels 200 located on the four sides of the virtual rectangle 510 are referred to... Figure 4 , Figure 5 All are located on the side of the virtual rectangle 510 closest to the center of the virtual rectangle 510, or, please refer to [link to relevant documentation]. Figure 1 , Figure 2 , Figure 7 , Figure 8 All are located on the side of the virtual rectangle 510 that is furthest from the center of the virtual rectangle 510. Figure 1 , 4 In section 7, it is easy to understand that the virtual rectangle is not drawn with dashed lines.

[0062] By moving the geometric center of the pixel with the largest light-emitting area, the gap between the adjacent first and second pixels is increased, so that the spacer unit is placed in the increased gap. When setting or moving the mask, the distance between the pixel evaporation opening of the mask and the spacer unit is increased, reducing the risk of scratching the spacer unit by the pixel evaporation opening of the mask, enhancing the packaging effect, improving product yield, and improving the display effect.

[0063] In some embodiments, please refer to Figure 9The display panel 100 includes an array substrate 110, a pixel definition layer 120 located on one side of the array substrate 110, and a spacer layer 130 located on the side of the pixel definition layer 120 away from the array substrate 110; wherein, the spacer layer 130 includes a plurality of spacer units 131, and the spacer units 131 are disposed between the first corner portion 210 and the adjacent second pixel 300.

[0064] The spacer layer 130 serves to buffer and block the flow of the film layer. The spacer units 131 are all arranged around the first corner portion 210. Compared with the second corner portion 220, the recessed first corner portion 210 has a larger arrangement space with the adjacent second pixel 300. When setting or moving the mask, the distance between the pixel evaporation opening of the mask and the spacer layer 130 is increased, reducing the risk of scratching the spacer layer 130, enhancing the encapsulation effect, improving product yield, and improving the display effect.

[0065] In some embodiments, please refer to Figure 9 The pixel definition layer 120 includes a plurality of first openings 121, a plurality of second openings, and a plurality of third openings. The first opening 121 corresponds to the first pixel 200, the second opening corresponds to the second pixel 300, and the third opening corresponds to the third pixel 400. The slope of the sidewall of the first corner portion 210 corresponding to the first opening 121 is greater than the slope of the sidewall of the second corner portion 220 corresponding to the first opening 121.

[0066] The display panel 100 further includes a light-emitting layer 140, which is located within the first opening 121, the second opening, and the third opening. The inward reduction of the first corner portion 210 reduces the light-emitting area of ​​the first pixel 200. The sidewall of the pixel opening on the pixel definition layer 120 has a certain slope. Increasing the slope of the sidewall of the first opening 121 corresponding to the inward reduction of the first corner portion 210 increases the filling volume of the light-emitting layer 140 within the first opening 121, thereby increasing the light-emitting brightness of the first pixel 200 to compensate for the reduced light-emitting area of ​​the inward reduction of the first corner portion 210, thereby improving the light-emitting quality of the first pixel 200 and improving the display effect.

[0067] In some embodiments, please refer to Figure 3 , Figure 6 , Figure 9In any of the first pixels 200, the distance from the first corner portion 210 to the first intersection point 230 is the third distance L3, and the distance from the second corner portion 220 to the first intersection point 230 is the fourth distance L4; wherein the ratio of the third distance L3 to the fourth distance L4 is 4:5 to 24:25.

[0068] If the inward size of the first type of corner portion 210 is too small, the distance between the pixel evaporation opening of the mask and the spacer layer 130 cannot be increased well when setting or moving the mask, and the risk of scratching the spacer layer 130 cannot be effectively reduced; if the inward size of the first type of corner portion 210 is too large, it will affect the light-emitting area of ​​the first pixel 200, reduce the light-emitting brightness of the first pixel 200, and affect the display effect.

[0069] In some embodiments, in the direction from the edge of the display panel 100 to the center of the display panel 100, the arrangement density and / or setting size of the spacer units 131 gradually increase, and the ratio of the third distance L3 to the fourth distance L4 gradually decreases.

[0070] The smaller the ratio of the third distance L3 to the fourth distance L4, the greater the inward retraction of the first corner portion 210, and the greater the setting space between the first corner portion 210 and the adjacent second pixel 300. When setting or moving the mask, the distance between the pixel evaporation opening of the mask and the spacer layer 130 is increased, reducing the risk of scratching the spacer layer 130, enhancing the encapsulation effect, improving product yield, and improving the display effect.

[0071] In some embodiments, in the direction from the edge of the display panel 100 to the center of the display panel 100, the arrangement density and / or size of the spacer units 131 gradually increase, and the slope of the sidewall of the first opening 121 corresponding to the first corner portion 210 gradually increases.

[0072] The slope of the sidewall of the first recessed corner portion 210 corresponding to the first opening 121 is increased, thereby increasing the filling volume of the light-emitting layer 140 in the first opening 121, thereby increasing the light-emitting brightness of the first pixel 200 to compensate for the reduced light-emitting area of ​​the recessed first corner portion 210, thereby improving the light-emitting quality of the first pixel 200 and improving the display effect.

[0073] In some embodiments, the array substrate 110 includes a substrate, an active layer on the substrate, a first insulating layer on the active layer, a gate layer on the first insulating layer, a second insulating layer on the gate layer, a source-drain layer on the second insulating layer, and a third insulating layer on the source-drain layer.

[0074] In some embodiments, the light-emitting device layer includes an anode layer on the third insulating layer, a light-emitting material layer on the anode layer, and a cathode layer on the light-emitting material layer. The display panel 100 further includes a pixel definition layer 120 disposed on the same layer as the light-emitting material layer, a polarizing layer on the light-emitting device layer, and a flexible cover plate on the polarizing layer. The display panel 100 also includes corresponding adhesive layers located between the polarizing layer and the flexible cover plate, between the light-emitting device layer and the polarizing layer, and between the back plate and the substrate.

[0075] In some embodiments, the light-emitting device layer may include OLED (Organic Light-Emitting Diode) material, or Micro LED or Mini LED, without specific limitations.

[0076] This invention moves the geometric center of the pixel with the largest luminous area, giving the virtual quadrilateral first and second type sides of unequal lengths. This increases the space between adjacent first and second pixels, allowing the spacer unit to be placed in the increased space. When setting or moving the mask, this increases the distance between the pixel evaporation opening of the mask and the spacer unit, reducing the risk of scratching the spacer unit by the pixel evaporation opening of the mask, enhancing the encapsulation effect, improving product yield, and improving display effect.

[0077] Please see Figure 11 The present invention also provides a display device 10, including a display panel 100 as described above.

[0078] In this embodiment, the display device 10 further includes a device body 20, which is integrated with the display panel 100.

[0079] For the specific structure of the display panel 100, please refer to any of the above-described embodiments of the display panel 100 and the accompanying drawings, which will not be repeated here.

[0080] In this embodiment, the main body 20 of the device may include a middle frame, frame adhesive, etc., and the display device 10 may be a display terminal such as a mobile phone, tablet, or television, which is not limited here.

[0081] This invention discloses a display panel and a display device. The display panel includes multiple first pixels, multiple second pixels, and multiple third pixels. The first pixels have the largest light-emitting area and are located on the four sides of a virtual rectangle. The second pixels are located at the four corners of the virtual rectangle and inside the virtual rectangle. The virtual rectangle includes four virtual quadrilaterals, and the geometric center of the first pixel is set on one side of the virtual rectangle. This invention increases the space between adjacent first and second pixels by moving the geometric center of the pixel with the largest light-emitting area, so that the geometric center of the first pixel is set on one side of the virtual rectangle. This allows the spacer unit to be placed in the increased space. When setting or moving the mask, the distance between the pixel evaporation opening of the mask and the spacer unit is increased, reducing the risk of scratching the spacer unit by the pixel evaporation opening of the mask, enhancing the packaging effect, improving product yield, and improving the display effect.

[0082] The above provides a detailed description of a display panel and display device provided by the embodiments of the present invention. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
