[0067] To make the objectives, technical solutions and advantages of the present application clearer, the following will describe the technical solutions of the present application completely through specific implementation manners in combination with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Without departing from the spirit or scope of the present application, various modifications and variations can be made in the present application, which are obvious to those skilled in the art. Therefore, the present application is intended to cover the modifications and variations of the present application that fall within the scope of the corresponding claims (the claimed technical solutions) and their equivalents.
[0068] It should be noted that the implementation manners provided by the embodiments of the present application can be combined with each other without conflict.
[0069] Currently, the pixel arrangement methods of OLED display panels include "RGBG" arrangement, "delta" arrangement, "diamond" arrangement, etc. Among them, the "RGBG" arrangement has blurred text, thick strokes, and blurred picture display; the "delta arrangement" has obvious font serrations in the displayed text; the "diamond" arrangement has clear text, thin strokes, and relatively slight serration feeling. However, there are still some technical problems to be solved in the "diamond" arrangement.
[0070] Exemplarily, Figure 1 It is a structural schematic diagram of a pixel arrangement structure in the related art, as Figure 1As shown, the pixel arrangement structure in the related art includes a first sub-pixel 11', a second sub-pixel 12', and a third sub-pixel 13'; the third sub-pixel 13' has a center that coincides with the center of the virtual square VS; the second sub-pixel 12' is spaced apart from the third sub-pixel 13' and has a center at the first vertex P1 of the virtual square VS; the first sub-pixel 11' is spaced apart from the second sub-pixel 12' and the third sub-pixel 13' and has a center at the second vertex P2 adjacent to the first vertex P1 of the virtual square VS. Since the included angle between two adjacent sides formed by the second sub-pixel 12' and the third sub-pixel 13' in this design solution is 90° and forms a virtual square VS, which is similar to a rhombus / diamond structure in shape, those skilled in the art habitually call it a "diamond" pixel arrangement.
[0071] The color edge effect of the "diamond" pixel arrangement structure is relatively serious. The so-called color edge effect means that when the display panel displays an image, obvious color stripes that deviate from the original image will appear at the image edge. The color edge effect includes magenta color edges and green color edges. Among them, the image edge includes red sub-pixels and blue sub-pixels. After the red sub-pixels and blue sub-pixels are mixed, magenta is formed, that is, when the image edge forms a magenta edge, it is a magenta color edge; the image edge includes green sub-pixels, and the image edge shows green, that is, when the image edge forms a green edge, it is a green color edge.
[0072] Exemplarily, as Figure 1 shown, the first sub-pixel 11' is a red sub-pixel, the second sub-pixel 12' is a blue sub-pixel, and the third sub-pixel 13' is a green sub-pixel. Figure 1 The first sub-pixel 11' and the second sub-pixel 12' in the area framed by the left dashed box form a magenta color edge; Figure 1 There is a column of third sub-pixels 13' in the area framed by the right dashed box, and the green color edge is serious; Figure 1 The first sub-pixel 11' and the second sub-pixel 12' in the area framed by the upper dashed box form a magenta color edge; Figure 1 There is a row of third sub-pixels 13' in the area framed by the lower dashed box, and the green color edge is serious. It can be seen that the color edge effect of the display panel in the related art is serious, which further affects the display effect of the display panel. Among them, the dashed box is used to mark the sub-pixel rows or columns at the edge position closest to the display area, so as to facilitate observing the display effect at the edge.
[0073] It should be noted that, in order to clearly show the area where the color edges appear, Figure 1 it is framed by a dashed box in . However, it can be understood that this dashed box does not actually exist.
[0074] In view of the above technical problems, embodiments of the present application provide a display panel, a manufacturing method, and a display device. Specifically, the display panel provided by the embodiments of the present application includes: a plurality of first sub-pixels, a plurality of second sub-pixels, and a plurality of third sub-pixels; the plurality of third sub-pixels form a first virtual trapezoid, the centers of the plurality of third sub-pixels are respectively located at the vertices of the first virtual trapezoid, and the first sub-pixels are located inside the first virtual trapezoid; the plurality of first sub-pixels and the second sub-pixels form a second virtual trapezoid, the center of the second sub-pixel is located at the first vertex of the second virtual trapezoid, the center of the first sub-pixel is located at the second vertex of the second virtual trapezoid, the first vertex and the second vertex are alternately spaced apart, and the third sub-pixels are located inside the second virtual trapezoid; the first virtual trapezoid includes a first long side, a first hypotenuse, a first short side, and a second hypotenuse connected in sequence; the second virtual trapezoid includes a second long side, a third hypotenuse, a second short side, and a fourth hypotenuse connected in sequence; the first long side and the first hypotenuse form a first angle, and the first long side and the second hypotenuse form a second angle; the second long side and the third hypotenuse form a third angle, and the second long side and the fourth hypotenuse form a fourth angle; wherein, the sum of the angles of the first angle and the second angle is a first angle, the sum of the angles of the third angle and the fourth angle is a second angle, and the difference between the first angle and the second angle is within a first preset range; the absolute value of the first preset range is greater than or equal to 0° and less than or equal to 10°.
[0075] With the above technical solution, four third sub-pixels form a first virtual trapezoid. That is, if at least one of the four third sub-pixels is offset, the number of the third sub-pixels that are separately exposed will become smaller, and the color edge phenomenon can be weakened; the centers of two first sub-pixels and two second sub-pixels form a second virtual trapezoid. That is, if the first sub-pixel or the second sub-pixel is offset, due to the offset of one of the sub-pixels, the color edge phenomenon can be weakened. At the same time, the difference between the first angle and the second angle of the two trapezoids is within the first preset range. On the one hand, the color edge phenomenon of all the edges of the display panel can be improved simultaneously; on the other hand, the offset amounts of the three sub-pixels can be adjusted so that the first virtual trapezoid and the second virtual trapezoid form regular figures with relatively small differences, and the effect is better when displaying text, ensuring display uniformity. In addition, the offset third sub-pixels can also be close to the other two sub-pixels, making the color edge become lighter. That is, compared with the "diamond arrangement", the display panel provided by the present implementation scheme can make the color edge effect become lighter and improve the display effect of the display panel.
[0076] The above is the core idea of the present application. Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application.
[0077] Figure 2 It is a schematic structural diagram of a display panel provided by an embodiment of the present application. Figure 3 is Figure 2A partially enlarged view of the display panel shown, as Figure 2 and Figure 3 shown, the display panel 100 provided by an embodiment of the present application includes: a plurality of first sub-pixels 11, a plurality of second sub-pixels 12, and a plurality of sub-pixels 13; a plurality of third sub-pixels 13 form a first virtual trapezoid 21, the centers of the plurality of third sub-pixels 13 are respectively located at the vertices of the first virtual trapezoid 21, and the first sub-pixels 11 are located inside the first virtual trapezoid 21; a plurality of first sub-pixels 11 and a plurality of second sub-pixels 12 form a second virtual trapezoid 22, the center of the second sub-pixel 12 is located at the first vertex of the second virtual trapezoid, the center of the first sub-pixel 11 is located at the second vertex of the second virtual trapezoid 22, the first vertex and the second vertex are alternately and spaced apart, and the third sub-pixels 13 are located inside the second virtual trapezoid 12.
[0078] Exemplarily, the first sub-pixels 11 are red sub-pixels, the second sub-pixels 12 are blue sub-pixels, and the third sub-pixels 13 are green sub-pixels. Continuing to refer to Figure 2 , the centers of the plurality of third sub-pixels 13 form a first virtual trapezoid 21. For example, the centers of four third sub-pixels 13 form a first virtual trapezoid 21, that is, compared with the "diamond" pixel arrangement, at least one of the four third sub-pixels 13 is offset. Among them, the offset of at least one third sub-pixel 13 means that the third sub-pixel 13 moves towards the edge of different display areas. On the one hand, when at least one of the four third sub-pixels 13 offsets towards the direction close to the first sub-pixels and the second sub-pixels located at the edge of the display area, the third sub-pixels can be mixed and displayed with the first sub-pixels and the second sub-pixels located at the edge of the display area, and the magenta color edge at the edge of the display area can be improved; on the other hand, compared with the "diamond" pixel arrangement, when the centers of at least two adjacent third sub-pixels 13 among the four third sub-pixels 13 are not on a straight line, one third sub-pixel offsets towards the edge of the display area relative to another third sub-pixel, and the number of third sub-pixels located at the edge of the display area decreases, and the sensitivity of the human eye to the row (or column) formed by the third sub-pixels at the edge of the display area decreases. In this way, the green color edge effect is weakened.
[0079] The centers of multiple first sub-pixels 11 and multiple second sub-pixels 12 form a second virtual trapezoid 22. For example, the centers of two first sub-pixels 11 and two second sub-pixels 12 form a second virtual trapezoid 22. That is, compared with the "diamond" pixel arrangement, at least one of the first sub-pixels 11 and the second sub-pixels 12 is offset. Among them, the offset of at least one of the first sub-pixels 11 and the second sub-pixels 12 means that the first sub-pixel 11 or the second sub-pixel 12 moves toward the edge of a different display area. On the one hand, multiple first sub-pixels or second sub-pixels are offset in the direction toward the edge of the display area. The row (or column) formed by the centers of multiple first sub-pixels and the row (or column) formed by the centers of multiple second sub-pixels are not on the same straight line, and they cannot form a magenta color edge effect. On the other hand, since one of the sub-pixels corresponding to the long side of the second virtual trapezoid 22 is offset. For example, the first sub-pixel or the second sub-pixel can be closer to the third sub-pixel 13 at the edge of the display area, making the distribution of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 more uniform, and improving the green color edge effect. That is, compared with the diamond arrangement, the display panel provided by this embodiment can make the color edge effect become milder. In this way, the display effect of the display panel can be improved.
[0080] It should be noted that the color edge effect refers to the appearance of obvious color stripes at the edge of the display area when a white solid color screen is lit. The improvement standard of the color stripes mainly is to judge whether the image color at the edge of the display area is the same as the white solid color image color in the display area, or to judge whether the sensitivity to the human eye is reduced. Among them, the general color stripes include magenta color edges and green color edges. The magenta color edge is the color edge formed by multiple red sub-pixels and blue sub-pixels, and the green color edge is the color edge formed by multiple green sub-pixels. For the magenta color edge, one improvement method is: borrowing green sub-pixels to mix and display with the magenta color edge, so that the centers of the red sub-pixels, blue sub-pixels, and green sub-pixels at the edge of the display area are close, and the formed image color is the same as the white image color formed by mixing the three sub-pixels in the display area, avoiding the appearance of color stripes that deviate from the image color in the display area at the edge of the display area, and weakening the magenta color edge. Another improvement method is: setting the red sub-pixels and blue sub-pixels at the edge of the display area on different rows (or columns). In this way, the row (or column) formed by the centers of multiple red sub-pixels and the row (or column) formed by the centers of multiple blue sub-pixels are not on the same straight line, and they cannot form a magenta color edge. At the same time, the row (or column) formed by the centers of the blue sub-pixels is located at the outermost edge, and the human eye has a lower sensitivity to the blue sub-pixels, thus improving the magenta color edge. Through the above two methods, the magenta color edge at the edge of the display area can be improved.
[0081] Meanwhile, for the green color fringe, one improvement method is as follows: reducing the number of green sub-pixels in the green color fringe to reduce the sensitivity of the human eye to the green color fringe, thereby weakening the green color fringe; another method: making the row (or column) formed by the green sub-pixels closest to the edge in the display area close to the row (or column) formed by the blue sub-pixels or red sub-pixels at the edge of the display area, and mixing the green color fringe with the red sub-pixels or blue sub-pixels for display to weaken the green color fringe.
[0082] Optionally, Figure 4 is a schematic structural diagram of another display panel provided by an embodiment of the present application. As Figure 4 shown, the display panel 100 provided by the embodiment of the present application further includes a display area AA; the display area includes at least one edge; the centers of the first sub-pixels 11 and the centers of the second sub-pixels 12 are located on the first virtual line Z1, the centers of the third sub-pixels 13 closest to the edge are located on the second virtual line Z2, and the centers of the third sub-pixels 13 second closest to the edge are located on the third virtual line Z3. The extending directions of the first virtual line Z1, the second virtual line Z2, and the third virtual line Z3 are substantially the same, and the spatial positions of the first virtual line Z1, the second virtual line Z2, and the third virtual line Z3 are different. Exemplarily, as Figure 4 shown, the extending directions of the first virtual line Z1, the second virtual line Z2, and the third virtual line Z3 are all, for example, the first direction, where the first direction includes the column direction; or, Figure 5 is a schematic structural diagram of another display panel provided by an embodiment of the present application. As Figure 5 shown, the first direction includes the row direction.
[0083] In this embodiment, the centers of multiple third sub-pixels 13 are respectively located on the second virtual line Z2 and the third virtual line Z3. When the third sub-pixels 13 are close to the edge, the number of the third sub-pixels 13 is small. In this way, the effect of weakening the green color fringe effect is achieved; when the first sub-pixels 11 and the second sub-pixels 12 are close to the edge, the third sub-pixels 13 can be mixed with the first sub-pixels 11 and the second sub-pixels 12 close to the edge to achieve the effect of weakening the magenta color fringe effect.
[0084] Optionally, continue to refer to Figure 4 and Figure 5 , the display area includes a first edge A1, and the third virtual line Z13 is located on the side of the second virtual line Z12 away from the first virtual line Z11.
[0085] Exemplarily, the first sub-pixels 11 are red sub-pixels, the second sub-pixels 12 are blue sub-pixels, and the third sub-pixels 13 are green sub-pixels. Please continue to refer to Figure 4 and Figure 5, the third virtual line Z13 is located on the side of the second virtual line Z12 away from the first virtual line Z11, that is, the third sub-pixel 13 centered on the second virtual line Z12 is more biased towards the first sub-pixel 11 and the second sub-pixel 12 centered on the first virtual line Z1. The green sub-pixel is mixed with the red sub-pixel and the blue sub-pixel. In this way, the magenta color edge caused by the first sub-pixel 11 and the second sub-pixel 12 centered on the first virtual line Z1 can be improved.
[0086] Based on the above solution, optionally, corresponding to the first long side of the first virtual trapezoid 21 and close to the first edge A1, there is an overlap between the third sub-pixel 13 and the first sub-pixel 11 and / or the second sub-pixel 12 in the first direction, so that the magenta color edge is further weakened.
[0087] Optionally, continue to refer to Figure 4 and Figure 5 , the display area includes a second edge A2. The third virtual line Z23 is located on the side of the second virtual line Z22 close to the first virtual line Z21, and the third virtual line Z23 is located between the first virtual line Z21 and the second virtual line Z22.
[0088] Exemplarily, the first sub-pixel 11 is a red sub-pixel, the second sub-pixel 12 is a blue sub-pixel, and the third sub-pixel 13 is a green sub-pixel. Please continue to refer to Figure 4 and Figure 5 , the third virtual line Z23 is located on the side of the second virtual line Z22 close to the first virtual line Z21, and the third virtual line Z23 is located between the first virtual line Z21 and the second virtual line Z22, that is, the third sub-pixel 13 centered on the third virtual line Z23 is more biased towards the side away from the second edge A2, and the third sub-pixel 13 centered on the second virtual line Z22 is biased towards the side of the second edge A2. That is, the number of third sub-pixels 13 located at the edge is reduced. In this way, the green color edge caused by the third sub-pixel 13 located at the edge can be improved. In addition, since the first sub-pixel 11 centered on the first virtual line Z21 is closer to the third sub-pixel 13 centered on the third virtual line Z23, in this way, the first sub-pixel 11 and the third sub-pixel 13 are mixed, further improving the green color edge caused by the third sub-pixel 13 located at the edge.
[0089] Based on the above embodiments, optionally, continue to refer to Figure 4 and Figure 5, the display panel 100 provided by the embodiments of the present application further includes a display area AA; the display area includes at least one edge; the center of the first sub-pixel 11 that is second closest to the edge is located on the fourth virtual line Z4, the center of the second sub-pixel 12 that is closest to the edge is located on the fifth virtual line Z5, the center of the third sub-pixel 13 is located on the sixth virtual line Z6, the extending directions of the fourth virtual line Z4, the fifth virtual line Z5, and the sixth virtual line Z6 are substantially the same, and the spatial positions of the fourth virtual line Z4, the fifth virtual line Z5, and the sixth virtual line Z6 are different. Exemplarily, as Figure 4 shown, the extending directions of the fourth virtual line Z4, the fifth virtual line Z5, and the sixth virtual line Z6 are, for example, all the second direction, where the second direction includes the row direction; or, Figure 5 is a schematic structural diagram of another display panel provided by the embodiments of the present application. As Figure 5 shown, the second direction includes the column direction.
[0090] In this embodiment, the center of the first sub-pixel 11 that is second closest to the edge is located on the fourth virtual line Z4, and the center of the second sub-pixel 12 that is closest to the edge is located on the fifth virtual line Z5, that is, the first sub-pixel 11 and the second sub-pixel 12 are staggered. When the first sub-pixel 11 and the second sub-pixel 12 are close to the edge, the effect of weakening the color fringe effect can be achieved; in addition, when the third sub-pixel 13 is close to the edge, due to the staggered arrangement of the first sub-pixel 11 and the second sub-pixel 12, one of the sub-pixels can be made to be more biased towards the third sub-pixel 13 and mixed with the third sub-pixel 13 to achieve the effect of weakening the color fringe effect.
[0091] Optionally, continue to refer to Figure 4 and Figure 5 , the display area includes a third edge A3, and the sixth virtual line Z16 is located on the side of the fourth virtual line Z14 away from the fifth virtual line Z15.
[0092] Exemplarily, the first sub-pixel 11 is a red sub-pixel, the second sub-pixel 12 is a blue sub-pixel, and the third sub-pixel 13 is a green sub-pixel. Please continue to refer to Figure 4 and Figure 5 , the sixth virtual line Z16 is located on the side of the fourth virtual line Z14 away from the fifth virtual line Z15, that is, the center is closer to the third sub-pixel located on the sixth virtual line Z16 for the fourth virtual line Z14. And because the center of the first sub-pixel 11 that is second closest to the edge is located on the fourth virtual line Z4, and the center of the second sub-pixel 12 that is closest to the edge is located on the fifth virtual line Z5, that is, the first sub-pixel 11 and the second sub-pixel 12 are staggered, making the distribution of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 more uniform. In this way, the magenta color fringe caused by the first sub-pixel 11 and the second sub-pixel 12 with the center on the same virtual line can be improved.
[0093] Optionally, continue to refer to Figure 4 and Figure 5 , the display area includes a fourth edge A4, a sixth virtual line Z26 is located on a side of the fourth virtual line Z24 away from the fifth virtual line Z25, and the fourth virtual line Z24 is located between the fifth virtual line Z25 and the sixth virtual line Z26.
[0094] Exemplarily, the first sub-pixel 11 is a red sub-pixel, the second sub-pixel 12 is a blue sub-pixel, and the third sub-pixel 13 is a green sub-pixel. Please continue to refer to Figure 4 and Figure 5 , the sixth virtual line Z26 is located on a side of the fourth virtual line Z24 away from the fifth virtual line Z25, and the fourth virtual line Z24 is located between the fifth virtual line Z25 and the sixth virtual line Z26, that is, the third sub-pixel 13 with the center located on the sixth virtual line Z26 is biased towards the side of the fourth edge A4, the center located on the fourth virtual line Z24 is closer to the third sub-pixel 13 with the center located on the sixth virtual line Z26, and the first sub-pixel 11 and the third sub-pixel 13 are mixed to improve the green color edge caused by the third sub-pixel 13 being located at the edge.
[0095] Based on the above solution, optionally, for the third sub-pixel 13 corresponding to the first long side of the first virtual trapezoid 21 and close to the fourth edge A4, there is an overlap with the first sub-pixel 11 and / or the second sub-pixel 12 in the second direction. In this way, the green color edge caused by the third sub-pixel 13 being located at the edge can be further improved.
[0096] It should be noted that Figure 4 takes the first edge A1 as the left edge of the display area AA, the second edge A2 as the right edge of the display area AA, the third edge A3 as the upper edge of the display area AA, and the fourth edge A4 as the lower edge of the display area AA as an example, and Figure 5 takes the first edge A1 as the upper edge of the display area AA, the second edge A2 as the lower edge of the display area AA, the third edge A3 as the left edge of the display area AA, and the fourth edge A4 as the right edge of the display area AA as an example for illustration, but it does not constitute a limitation to this application. Those skilled in the art can set the positions of the sub-pixels according to the actual situation, but the color edge effect problem existing in the display panel can be solved by adopting this solution.
[0097] Continue to refer to Figure 2 and Figure 3, the first virtual trapezoid 21 includes a first long side 211, a first hypotenuse 212, a first short side 213, and a second hypotenuse 214 connected in sequence; the second virtual trapezoid 22 includes a second long side 221, a third hypotenuse 222, a second short side 223, and a fourth hypotenuse 224 connected in sequence; the first long side 211 and the first hypotenuse 212 form a first included angle α1, and the first long side 211 and the second hypotenuse 214 form a second included angle α2; the second long side 221 and the third hypotenuse 222 form a third included angle β1, and the second long side 221 and the fourth hypotenuse 224 form a fourth included angle β2. Among them, the sum of the angles of the first included angle α1 and the second included angle α2 is the first angle, the sum of the angles of the third included angle β1 and the fourth included angle β2 is the second angle, and the difference between the first angle and the second angle is within a first preset range.
[0098] In this implementation, since the sum of the angles of the first included angle α1 and the second included angle α2 is the first angle, the sum of the angles of the third included angle β1 and the fourth included angle β2 is the second angle, and the difference between the first angle and the second angle is within a first preset range. Optionally, the first preset range can be, for example, greater than or equal to 0° and less than or equal to 10°. Optionally, the first preset range can be, for example, greater than or equal to 0° and less than or equal to 4°. Optionally, the first preset range can be, for example, greater than or equal to 0° and less than or equal to 5°. Optionally, the first preset range can be, for example, greater than or equal to 0° and less than or equal to 6°. Exemplarily, the first preset range can be 0°, 5°, 10°, which can ensure that each sub-pixel has an optimal arrangement, no obvious hollow area, effectively avoid obvious interval gaps, avoid space waste, and ensure the display effect of the display panel 100.
[0099] Among them, the range of the first included angle α1 can satisfy, for example, 82° ≤ α1 ≤ 88°, and can be, for example, 82°, 83°, 84°, 85°, 86°, 87°, 88°, etc.; optionally, the range of α1 satisfies 83° ≤ α1 ≤ 86°, and can be, for example, 83°, 86°, etc.; the first long side 211 and the second hypotenuse 214 form a second included angle α2. Among them, the range of the second included angle α2 can satisfy, for example, 82° ≤ α2 ≤ 88°, and can be, for example, 82°, 83°, 84°, 85°, 86°, 87°, 88°, etc.; optionally, the range of α2 satisfies 83° ≤ α2 ≤ 86°, and can be, for example, 83°, 86°, etc.; the second long side 221 and the third hypotenuse 222 form a third included angle β1. Among them, the range of the third included angle β1 can satisfy, for example, 82° ≤ β1 ≤ 88°, and can be, for example, 82°, 83°, 84°, 85°, 86°, 87°, 88°, etc.; optionally, the range of β1 satisfies 83° ≤ β1 ≤ 86°, and can be, for example, 83°, 86°, etc.; the second long side 221 and the fourth hypotenuse 224 form a fourth included angle β2. Among them, the range of the fourth included angle β2 can satisfy, for example, 82° ≤ β2 ≤ 88°, and can be, for example, 82°, 83°, 84°, 85°, 86°, 87°, 88°, etc.; optionally, the range of β2 satisfies 83° ≤ β2 ≤ 86°, and can be, for example, 83°, 86°, etc.
[0100] It should be noted that when the resolution of the display panel is fixed, when the virtual rectangular shape arranged in diamond changes to the virtual trapezoidal shape of the present application, the virtual trapezoidal shape includes two hypotenuses, a short side, and a long side. When the included angle between the two hypotenuses and the long side changes, the distances of the hypotenuse, the long side, and the short side also change accordingly. For example, when the included angle between the two hypotenuses and the long side is 86°, this included angle becomes smaller compared to the 90° included angle of the diamond arrangement. The corresponding hypotenuse of the virtual trapezoid will gradually become longer, the corresponding long side of the virtual trapezoid will gradually become longer, and the corresponding short side of the virtual trapezoid will become shorter accordingly.
[0101] Exemplarily, Table 1 shows the cases of the color edge effect when the first included angle α1 of the first virtual trapezoid 21, the second included angle α2 of the first virtual trapezoid 21, the third included angle β1 of the second virtual trapezoid 22, and the fourth included angle β2 of the second virtual trapezoid 22 are equal and are 90°, 88°, 86°, 83°, 81°, and 76°. Figure 6 is the structure of the display panel when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 88°. Figure 7 is the structure of the display panel when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 86°. Figure 8It is the structure of the display panel when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 83°. Figure 9 It is the structure of the display panel when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 81°. Figure 10 It is the structure of the display panel when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 76°.
[0102] It should be noted that the above examples are only illustrated with the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 being equal. However, the present application is not limited to this. In other alternative embodiments, it may also be that the first included angle α1 is equal to the second included angle α2, the third included angle β1 is equal to the fourth included angle β2, but the first included angle α1 is greater than the third included angle β1.
[0103] Table 1
[0104]
[0105] See Figure 1 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 As shown in, and Table 1, when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 90°, the left magenta color edge is severe, the right green color edge is severe, the upper magenta color edge is severe, and the lower green color edge is severe. For specific explanations, refer to the foregoing content and will not be elaborated here.
[0106] When the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 88°, for the left edge, the offset angle of the third sub-pixel is relatively small, and the distances between the first sub-pixel, the second sub-pixel, and the offset third sub-pixel on the left edge are relatively large, and the sharing effect of the three sub-pixels is not good, and the left magenta edge is relatively severe; for the right edge, the offset angle of the third sub-pixel is relatively small, and the offset amount of the two third sub-pixels along the column direction is very small, and the green color edge is relatively severe; for the upper edge, the offset amounts of the first sub-pixel and the second sub-pixel in the row direction are relatively small, and the first sub-pixel part shares with the second sub-pixel, and the magenta edge is relatively severe; for the lower edge, since the offset amount of the first sub-pixel is relatively small, the distances between the two third sub-pixels and the first sub-pixel are relatively large, and the sharing effect of the two third sub-pixels and the first sub-pixel is not good, and the lower green color edge is relatively severe. It can be seen that when the included angles of the two trapezoids are both 88°, the improvement of the color edges on the side is not good.
[0107] When the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 86°, for the left edge, the offset angle of the third sub-pixel is moderate, the distances between the first sub-pixel, the second sub-pixel on the left edge and the offset third sub-pixel are moderate, the common effect of the three sub-pixels is obvious, and the left magenta edge is slight; for the right edge, the third sub-pixels in odd rows are offset inward, the centers of the two third sub-pixels are inward, the number of third sub-pixels in the green color edge decreases, and at the same time, the first sub-pixel is offset downward and is closer to the third sub-pixels in even rows, the green color edge is slight. At the same time, since the offset amounts of the two third sub-pixels along the column direction are moderate, the right edge presents a basically straight edge without sawtooth deformation; for the upper edge, the offset amounts of the first sub-pixel and the second sub-pixel in the row direction are moderate, the first sub-pixel is offset downward and is closer to the third sub-pixel. Compared with the diamond arrangement where the centers of the first sub-pixel and the second sub-pixel are on one straight line and the center of the third sub-pixel is on another straight line, when the included angles are all 86°, the center of gravity of the first sub-pixel is closer to the third sub-pixel, and the color centers of the three colors are more evenly distributed, improving the magenta bias on the upper side; for the lower edge, the first sub-pixel is offset downward and is closer to the edge of the third sub-pixel, and the first sub-pixel and the second sub-pixel are shared, and the lower green color edge is slight. At the same time, from the overall effect, since the included angles of the two trapezoids are both 86°, the distance between the first sub-pixel and the second sub-pixel is moderate, and there are no problems of color mixing and light stealing between the first sub-pixel and the second sub-pixel. It can be seen that when the included angles of the two trapezoids are both 86°, the overall display and the displays of the four side edges are all better.
[0108] When the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 83°, for the left edge, the offset angle of the third sub-pixel is moderate, the distances between the first sub-pixel, the second sub-pixel on the left edge and the offset third sub-pixel are moderate, the common effect of the three sub-pixels is obvious, and the left magenta edge is slight; for the right edge, the two third sub-pixels are offset along the column direction, the number of third sub-pixels in the green color edge decreases, the green color edge is slight, but because the offset amount of the two third sub-pixels along the column direction becomes larger, the right edge presents a zigzag shape, and edge sawtooth deformation occurs; for the upper edge, the offset amounts of the first sub-pixel and the second sub-pixel in the row direction are moderate, the distance between the first sub-pixel and the second sub-pixel becomes larger, and the magenta edge is slight; for the lower edge, because the offset amount of the first sub-pixel is moderate, the distances between the two third sub-pixels and the first sub-pixel are close, and the common effect of the two third sub-pixels and the first sub-pixel is obvious, and the lower green color edge is slight. At the same time, from the overall effect, because the included angles of the two trapezoids are both 83°, the included angles of the two trapezoids become smaller, the short sides corresponding to the trapezoids become shorter, the distance between the first sub-pixel and the second sub-pixel is relatively close, and there are problems of color mixing and light stealing between the first sub-pixel and the second sub-pixel, and the overall display effect is not good. It can be seen that when the included angles of the two trapezoids are both 83°, the display effects of the left, upper, and lower edges are better, but the right edge and the overall display effect are worse.
[0109] When the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 81°, for the left edge, the offset angle of the third sub-pixel is moderate, the distances between the first sub-pixel, the second sub-pixel on the left edge and the offset third sub-pixel are moderate, the common effect of the three sub-pixels is obvious, and the left magenta edge is slight; for the right edge, the two third sub-pixels are offset along the column direction, the number of third sub-pixels in the green color edge decreases, the green color edge is slight, but because the offset amount of the two third sub-pixels along the column direction becomes larger, the right edge presents a zigzag shape, and edge sawtooth deformation occurs; for the upper edge, the offset amounts of the first sub-pixel and the second sub-pixel in the row direction are moderate, the distance between the first sub-pixel and the second sub-pixel becomes larger, and the magenta edge is slight; for the lower edge, because the offset amount of the second sub-pixel is moderate, the distances between the two third sub-pixels and the second sub-pixel are close, and the common effect of the two third sub-pixels and the second sub-pixel is obvious, and the lower green color edge is slight. At the same time, from the overall effect, because the included angles of the two trapezoids are both 81°, the included angles of the two trapezoids become smaller, the short sides corresponding to the trapezoids become shorter, the distance between the first sub-pixel and the second sub-pixel is close, and there are problems of color mixing and light stealing between the first sub-pixel and the second sub-pixel, and the overall display effect is not good. It can be seen that when the included angles of the two trapezoids are both 81°, the display effects of the left, upper, and lower edges are better, but the right edge and the overall display effect are even worse.
[0110] When the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 76°, for the left edge, the offset angle of the third sub-pixel is moderate, the distances between the first sub-pixel, the second sub-pixel on the left edge and the offset third sub-pixel are moderate, and the common effect of the three sub-pixels is obvious, and the left magenta edge is slight; for the right edge, the two third sub-pixels are offset along the column direction, the number of third sub-pixels in the green color edge decreases, and the green color edge is slight. However, due to the large offset amount of the two third sub-pixels along the column direction, the right edge presents an obvious zigzag shape, and a serious edge sawtooth deformation phenomenon occurs; for the upper edge, the offset amounts of the first sub-pixel and the second sub-pixel in the row direction are moderate, the distances between the first sub-pixel and the second sub-pixel become larger, and the magenta edge is slight; for the lower edge, due to the moderate offset amount of the second sub-pixel, the distances between the two third sub-pixels and the second sub-pixel are close, and the common effect of the two third sub-pixels and the second sub-pixel is obvious, and the lower green color edge is slight. At the same time, from the overall effect, since the included angles of the two trapezoids are both 76°, the included angles of the two trapezoids become smaller, the short sides corresponding to the trapezoids become shorter, the distances between the first sub-pixel and the second sub-pixel are very close, and there are serious color mixing and light stealing problems between the first sub-pixel and the second sub-pixel, and the overall display effect is not good. Thus, it can be seen that when the included angles of the two trapezoids are both 76°, the display effects of the left, upper, and lower edges are better, but the right edge and the overall display effect are very poor.
[0111] In summary, when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 90°, there is a serious color edge effect on the side, and the side display effect is very poor; when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 86°, the color edge effect on the side is improved, and the overall display effect is good; when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 83°, some side effects are improved, but the right side and the overall display effects are relatively poor, bringing new problems, such as: the edge is sawtooth-shaped, and there are color mixing or light stealing problems between sub-pixels; when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 81°, some side effects are improved, but the right side and the overall display effects are even worse; when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 76°, some side effects are improved, but the right side and the overall display effects are very poor. Thus, it can be seen that when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 86°, both the overall display and the side display are good.
[0112] It should be noted that the above examples only illustrate the color edge effect according to the Figures 1 - 10 structure of the display panel shown, that is, the above up, down, left, and right only refer to the Figures 1 - 10 display panel shown, and do not represent the actual up, down, left, and right of the display panel.
[0113] It should be noted that the above examples only illustrate the case where the first sub-pixel 11 is a red sub-pixel, the second sub-pixel 12 is a blue sub-pixel, and the third sub-pixel 13 is a green sub-pixel, but do not constitute a limitation to this application. In other alternative embodiments, the emission colors of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 can also be changed, that is, the emission colors of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are different. Optionally, the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are respectively one of a red sub-pixel, a blue sub-pixel, and a green sub-pixel and are different from each other. Exemplarily, the first sub-pixel 11 can be a blue sub-pixel, the second sub-pixel 12 can be a red sub-pixel, and the third sub-pixel 13 can be a green sub-pixel.
[0114] Optionally, the first virtual trapezoid 21 and the second virtual trapezoid 22 can be, for example, an isosceles trapezoid or a right trapezoid, etc.
[0115] It should be noted that Figures 2 - 10 in, only the case where the shapes of the first sub-pixel 11 and the second sub-pixel 12 are both squares and the shape of the third sub-pixel 13 is an octagon is taken as an example for exemplary illustration. The embodiments of this application do not make special limitations on the shapes of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13. The boundaries of the square and the octagon represent the opening boundaries of the corresponding sub-pixels. Taking the display panel as an organic light-emitting display panel as an example, the boundaries of the square and the octagon are the boundaries of the sub-pixel effective openings of the pixel definition layer (PDL layer), representing the effective light-emitting area (opening area) of the light-emitting layer of the sub-pixel.
[0116] The wireframe around the first sub-pixel 11 represents the virtual edge 111 of the first sub-pixel 11, the wireframe around the second sub-pixel 12 represents the virtual edge 121 of the second sub-pixel 12, and the wireframe around the third sub-pixel 13 represents the virtual edge 131 of the third sub-pixel 13. Among them, the virtual edge refers to the outer boundary of the sub-pixel when the mask plate blocks, and does not actually exist. Optionally, please continue to refer to Figure 2 , in the pixel unit 10, the virtual edge 111 of the first sub-pixel 11 corresponding to the short side of the second virtual trapezoid 22 intersects with the virtual edge 121 of the second sub-pixel 12, and the virtual edge 111 of the first sub-pixel 11 corresponding to the long side of the second virtual trapezoid 22 is connected to the virtual edge 121 of the second sub-pixel 12. In this way, the arrangement of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 can be made more compact, avoiding waste of space.
[0117] It should also be noted that Figure 2Only one pixel arrangement structure is shown, that is, the first long side 211 and the first short side 213 of the first virtual trapezoid 21 extend along the X direction, and the second long side 221 and the second short side 223 of the second virtual trapezoid 22 extend along the Y direction, but this does not limit the present application. For example, it can also be that the first long side 211 and the first short side 213 of the first virtual trapezoid 21 extend along the X direction, and the second long side 221 and the second short side 223 of the second virtual trapezoid 22 extend along the X direction (as Figure 11 shown).
[0118] It should also be noted that the centers of the sub-pixels (the center of the first sub-pixel 11, the center of the second sub-pixel 12, and the center of the third sub-pixel 13) refer to the geometric centers of the light-emitting regions of the sub-pixels, that is, the centers of the light-emitting layers of the sub-pixels, which can be specifically determined according to the shapes of the sub-pixels. In this embodiment, the shapes of the first pixel 11 and the second sub-pixel 12 are squares, and the shape of the third sub-pixel 13 is an octagon as an example for exemplary illustration.
[0119] Optionally, the first included angle α1 is equal to the second included angle α2, and the third included angle β1 is equal to the fourth included angle β2. That is to say, the first virtual trapezoid 21 is an isosceles trapezoid, and the second virtual trapezoid 22 is also an isosceles trapezoid. In this way, the pixel arrangement is made more uniform and compact, ensuring the display effect of the display panel.
[0120] Optionally, the first included angle α1 is equal to the third included angle β1, that is, the angles of the included angles between the first virtual trapezoid 21 and the second virtual trapezoid 22 are the same, further making the pixel arrangement more uniform and compact, ensuring the display effect of the display panel. Exemplarily, the angle of the first included angle α1 is 86°, the angle of the second included angle α2 is 86°, the angle of the third included angle β1 is 86°, and the angle of the fourth included angle β2 is 86°.
[0121] Optionally, the first included angle α1 is greater than the third included angle β1. In this way, it can be ensured that the opening of the third sub-pixel 13 is larger and the display effect is better. Exemplarily, the angle of the first included angle α1 is 86°, the angle of the second included angle α2 is 86°, the angle of the third included angle β1 is 83°, and the angle of the fourth included angle β2 is 83°; Exemplarily, the angle of the first included angle α1 is 88°, the angle of the second included angle α2 is 88°, the angle of the third included angle β1 is 86°, and the angle of the fourth included angle β2 is 86°.
[0122] Optionally, the light-emitting areas of the third sub-pixels 13 are equal.
[0123] Such as Figure 1As shown, four third sub-pixels 13 surround a first sub-pixel 11, and / or four third sub-pixels 13 surround a second sub-pixel 12. Thus, when the setting area of the third sub-pixel 13 is determined, the setting areas of the first sub-pixel 11 and the second sub-pixel 12 can be determined. In this embodiment, by setting the emission areas of the third sub-pixels 13 to be equal, the design and manufacturing process difficulty can be reduced.
[0124] Optionally, continue to refer to Figure 2 and Figure 3 , the center of the third sub-pixel 13 does not overlap with the intersection point T1 of the two diagonals of the second virtual trapezoid 22, that is, the center of the third sub-pixel 13 is offset relative to the intersection point T1 of the two diagonals of the second virtual trapezoid 22 and does not intersect with the intersection point T1 of the two diagonals of the second virtual trapezoid 22.
[0125] This is because it is considered that the centers of the two first sub-pixels 11 and the two second sub-pixels 12 surrounding the third sub-pixel 13 form the second virtual trapezoid 22, making the area surrounded by the centers of the two first sub-pixels 11 and the two second sub-pixels 12 larger. Therefore, by making the center of the third sub-pixel 13 not overlap with the intersection point T1 of the two diagonals of the second virtual trapezoid 22, in this way, it can be ensured that the pixel aperture of the third sub-pixel 13 is larger, and it can also make the distance between the third sub-pixel 13 and its surrounding sub-pixels relatively close, improving the display effect of the display panel.
[0126] Optionally, continue to refer to Figure 2 and Figure 3 , the distance between the center of the third sub-pixel 13 and the intersection point T1 of the two diagonals of the second virtual trapezoid 22 is 1μm ≤ L ≤ 5μm. Exemplarily, the distance L between the center of the third sub-pixel 13 and the intersection point T1 of the two diagonals of the second virtual trapezoid 22 is 1μm, 2μm, 3μm, 3.5μm, 3.8μm, 4μm, and 5μm, etc.
[0127] Optionally, the distances from the centers of the two first sub-pixels 11 and the two second sub-pixels 12 surrounding the third sub-pixel 13 to the center of the third sub-pixel 13 are the first distance L1, the second distance L2, the third distance L3, and the fourth distance L4 respectively, where the first distance L1, the second distance L2, the third distance L3, and the fourth distance L4 are all not equal to ensure a better display effect of the display panel.
[0128] Optionally, Figure 12 is a partial structural schematic diagram of another display panel provided by an embodiment of the present application. As Figure 12As shown, the second virtual trapezoid 22 includes a first diagonal 225 and a second diagonal 226; two end points of the first diagonal 225 respectively coincide with centers of two first sub-pixels 11 adjacent to the same third sub-pixel 13; two end points of the second diagonal 226 respectively coincide with centers of two second sub-pixels 12 adjacent to the same third sub-pixel 13; wherein, a distance M1 from the center of the third sub-pixel 13 to the first diagonal 225 satisfies: 0.5 μm ≤ M1 ≤ 3.5 μm.
[0129] Generally, the structure of an OLED display device mainly includes multiple light-emitting sub-pixels, such as: a red sub-pixel, a blue sub-pixel, and a green sub-pixel. Among them, each light-emitting pixel includes an anode, a hole injection layer, a hole transport layer, a light-emitting layer, an electron transport layer, an electron injection layer, and a cathode. When a driving voltage is provided to the anode and the cathode, holes in the anode move towards the light-emitting layer through the hole injection layer and the hole transport layer, and electrons in the cathode move towards the light-emitting layer through the electron injection layer and the electron injection layer respectively, so as to recombine in the light-emitting layer to emit photons, realizing pixel light emission.
[0130] Among them, the hole injection layer, the hole transport layer, the light-emitting layer, the electron transport layer, and the electron injection layer are all formed by evaporation through a whole-surface mask plate, covering the entire pixel region. When controlling a certain light-emitting pixel to emit light, while holes flow from the anode to the cathode, a lateral leakage current will also be generated, reaching adjacent light-emitting pixels through the hole transport layer and the hole injection layer, thus causing other color light-emitting pixels to steal light. Regarding the light stealing between multiple different color sub-pixels, mainly taking the turn-on voltage of the sub-pixels as a standard, the larger the turn-on voltage of the sub-pixels corresponding to a pure color picture, the easier it is to provide holes to the sub-pixels with a smaller turn-on voltage, thus causing the problem of light stealing in the sub-pixels with a smaller turn-on voltage. Among the above three color sub-pixels, the blue sub-pixel has the largest turn-on voltage, the green sub-pixel has a relatively large turn-on voltage, and the red sub-pixel has the smallest turn-on voltage. Therefore, when a green pure color picture is lit, the red sub-pixel is prone to leakage current. At the same time, in order to reduce the lateral leakage current between adjacent different color sub-pixels during pure color picture display and reduce the risk of sub-pixel light stealing, generally, the size of the opposite faces of two adjacent different color sub-pixels is reduced, or the distance between two adjacent different color sub-pixels is increased. Among them, the size of the opposite face refers to the overlapping length of two adjacent sides facing each other of two adjacent different color sub-pixels.
[0131] Exemplarily, the first sub-pixel 11 is a red sub-pixel, the second sub-pixel 12 is a blue sub-pixel, and the third sub-pixel 13 is a green sub-pixel. As Figure 12As shown, the distance M1 from the center of the third sub-pixel 13 to the first diagonal line 225, relative to the intersection of the first diagonal line 225 and the second diagonal line 226 where the center of the third sub-pixel is located, the relative surface size of the third sub-pixel 13 and the first sub-pixel 11 decreases, and the distance between the third sub-pixel and two adjacent first sub-pixels increases, which can reduce the lateral leakage current between the third sub-pixel 13 and the two first sub-pixels 11 respectively, thereby reducing the risk of light stealing between the third sub-pixel 13 and the first sub-pixel 11.
[0132] It should be noted that the distance M1 from the center of the third sub-pixel 13 to the first diagonal line is a fixed distance, and this distance is, for example, in the range of 0.5 μm to 3.5 μm. For example, it can be 0.5 μm, 1 μm, 1.5 μm, 2 μm, 2.7 μm, 3 μm, 3.5 μm, etc., which can reduce the leakage current between sub-pixels, and further avoid the problem of light stealing between sub-pixels.
[0133] Optionally, continue to refer to Figure 12 , the center of the third sub-pixel 13 overlaps with the second diagonal line 226. During the product verification process, the relative surface sizes of the third sub-pixel 13 and the two second sub-pixels 12 corresponding to the second virtual trapezoid 22 can be kept basically unchanged, while the relative surface sizes of the third sub-pixel 13 and the two first sub-pixels 11 decrease, which can reduce the lateral leakage current of the first sub-pixel 11. The advantage of such a setting is that it can not only avoid the problem of light stealing between sub-pixels, but also enable the third sub-pixel 13 to be preferably distributed within the area surrounded by the two first sub-pixels 11 and the two second sub-pixels 12, ensuring a better display effect of the display panel.
[0134] Optionally, Figure 13 is a partial structural schematic diagram of another display panel provided by an embodiment of the present application. As Figure 13 shown, the second virtual trapezoid 22 includes a first diagonal line 225 and a second diagonal line 226; the two endpoints of the first diagonal line 225 respectively coincide with the centers of two first sub-pixels 11 adjacent to the same third sub-pixel 13; the two endpoints of the second diagonal line 226 respectively coincide with the centers of two second sub-pixels 12 adjacent to the same third sub-pixel 13; the center of the third sub-pixel 13 overlaps with the perpendicular bisector 228 of the first diagonal line 225. The advantage of such a setting is that it can not only avoid the problem of light stealing between sub-pixels, but also make the distances between the third sub-pixel 13 and two adjacent first sub-pixels 11 the same, and the improvement degrees of the lateral leakage currents of the two adjacent first sub-pixels 11 are similar, so that the improvement effect of the lateral leakage current of the first sub-pixels 11 within the second virtual trapezoid 22 is better.
[0135] Optionally, the distances from the center of the third sub-pixel 13 to the centers of the two first sub-pixels 11 corresponding to the first diagonal line 225 are equal. In this way, it is possible to avoid the problem of poor display effect when the distances from the center of the third sub-pixel 13 to the centers of the two first sub-pixels 11 corresponding to the first diagonal line 225 are unequal, and ensure that the display panel has a good display effect.
[0136] Optionally, Figure 14 is a partial structural schematic diagram of a display panel provided by an embodiment of the present application. As Figure 14 shown, the perpendicular bisector corresponding to the first diagonal line 225 is the first perpendicular bisector 228, and the perpendicular bisector corresponding to the second diagonal line 226 is the second perpendicular bisector 227; the center of the third sub-pixel 13 overlaps with the intersection point of the first perpendicular bisector 228 and the second perpendicular bisector 227. That is, the center of the third sub-pixel 13 is offset relative to the intersection point of the two diagonal lines (the first diagonal line 225 and the second diagonal line 226) of the second virtual trapezoid 22, that is, the center of the third sub-pixel 13 overlaps with the intersection point of the two perpendicular bisectors (the first perpendicular bisector 228 and the second perpendicular bisector 227). Since the center of the third sub-pixel 13 is located at the centroid of the area surrounded by the two first sub-pixels 11 and the second sub-pixel 12, it is possible to ensure that the display panel has a good display effect.
[0137] Optionally, continue to refer to Figure 14 , the distances from the centers of the two first sub-pixels 11 and the two second sub-pixels 12 surrounding the third sub-pixel 13 to the center of the third sub-pixel 13 are the fifth distance L5, the sixth distance L6, the seventh distance L7, and the eighth distance L8 respectively. Among them, the fifth distance L5, the sixth distance L6, the seventh distance L7, and the eighth distance L8 are all equal. In this way, it is ensured that the display panel has a good display effect.
[0138] As can be seen from the above embodiments, when the center of the third sub-pixel 13 is offset, there are three cases of the offset method: the first case is that the center of the third sub-pixel 13 is offset relative to the intersection point T1 of the two diagonal lines of the second virtual trapezoid 22; the second case is that the center of the third sub-pixel 13 is offset relative to the perpendicular bisector of the second diagonal line of the second virtual trapezoid 22; the third case is that the center of the third sub-pixel 13 is offset relative to the intersection point of the two diagonal lines of the second virtual trapezoid 22 and coincides with the intersection point of the corresponding two perpendicular bisectors of the second virtual trapezoid. Through the above three methods of offset, it is possible to ensure that the display panel has a good display effect.
[0139] Optionally, Figure 15 is a structural schematic diagram of another display panel provided by an embodiment of the present application. As Figure 15As shown, the light-emitting areas of two first sub-pixels 11 adjacent to the same third sub-pixel 13 are different; the light-emitting areas of two second sub-pixels 12 adjacent to the same third sub-pixel 13 are different. That is, the light-emitting area of the first sub-pixel 11 corresponding to the second long side of the second virtual trapezoid is different from the light-emitting area of the first sub-pixel 11 corresponding to the second short side of the second virtual trapezoid, and the light-emitting area of the second sub-pixel 12 corresponding to the second long side of the second virtual trapezoid is different from the light-emitting area of the second sub-pixel 12 corresponding to the second short side of the second virtual trapezoid 22. In this way, the arrangement of each sub-pixel can be made compact, and the display effect of the display panel can be improved.
[0140] Optionally, Figure 16 is a schematic structural diagram of another display panel provided by an embodiment of the present application. As Figure 16 shown, among the four third sub-pixels 13 surrounding the first sub-pixel 11, the light-emitting areas of the third sub-pixels 13 arranged in the first direction are the same, and the light-emitting areas of the third sub-pixels 13 arranged in the second direction are different; wherein, the first direction is the row direction, and the second direction is the column direction. Or, Figure 17 is a schematic structural diagram of another display panel provided by an embodiment of the present application. As Figure 17 shown, among the four third sub-pixels 13 surrounding the first sub-pixel 11, the light-emitting areas of the third sub-pixels 13 arranged in the first direction are the same, and the light-emitting areas of the third sub-pixels 13 arranged in the second direction are different; wherein, the first direction is the column direction, and the second direction is the row direction.
[0141] Since, in a pixel unit 10, the distance between two third sub-pixels 13 corresponding to the first long side of the first virtual trapezoid 21 is different from the distance between two third sub-pixels 13 corresponding to the first short side of the first virtual trapezoid 21, therefore, by setting the light-emitting areas of two third sub-pixels 13 corresponding to the first long side of the first virtual trapezoid 21 to be different from the light-emitting areas of two third sub-pixels 13 corresponding to the first short side of the first virtual trapezoid 21, even if the distance between two third sub-pixels 13 corresponding to the first long side of the first virtual trapezoid 21 is different from the distance between two third sub-pixels 13 corresponding to the first short side of the first virtual trapezoid 21, a good display effect can be ensured.
[0142] Optionally, continue to refer to Figure 16 or Figure 17 , the light-emitting areas of two third sub-pixels 13 corresponding to the first long side of the first virtual trapezoid 21 are larger than the light-emitting areas of two third sub-pixels 13 corresponding to the first short side of the first virtual trapezoid 21.
[0143] In this embodiment, the luminous areas of the two third sub-pixels 13 corresponding to the first long side of the first virtual trapezoid 21 are larger than the luminous areas of the two third sub-pixels 13 corresponding to the first short side of the first virtual trapezoid 21, which can avoid the problem of uneven display caused by the large distance between the two third sub-pixels 13 corresponding to the first long side of the first virtual trapezoid 21 and the small distance between the two third sub-pixels 13 corresponding to the first short side of the first virtual trapezoid 21 when the luminous areas of the third sub-pixels 13 are the same, and ensure a good display effect.
[0144] Optionally, continue to refer to Figure 2 and Figure 3 , the second short side 223 includes a first end point 2231 and a second end point 2232; the second long side 221 includes a third end point 2211 and a fourth end point 2212; the third hypotenuse 222 connects the first end point 2231 and the third end point 2211, and the fourth hypotenuse 224 connects the second end point 2232 and the fourth end point 2212; the foot of the perpendicular from the first end point 2231 to the second long side 221 is the first foot of the perpendicular C1, the distance from the first foot of the perpendicular C1 to the third end point 2211 is the ninth distance L9, the foot of the perpendicular from the second end point 2232 to the second long side 221 is the second foot of the perpendicular C2, the distance from the second foot of the perpendicular C2 to the fourth end point 2212 is the tenth distance L10, and the tenth distance L10 is less than or equal to the ninth distance L9; wherein, the length value of the ninth distance L9 is x, and the length value of the distance between the first foot of the perpendicular C1 and the second foot of the perpendicular C2 is y, 0 < x ≤ 3 / 16 (x + y), that is, even if the third end point 2211 is offset relative to the first foot of the perpendicular C1 and the fourth end point 2212 is offset relative to the second foot of the perpendicular C2, the maximum offset value x of the offset satisfies 0 < x ≤ 3 / 16 (x + y). In this way, it is possible to avoid the influence on the display effect due to excessive offsets of the third end point 2211 and the fourth end point 2212.
[0145] Similarly, the first short side 213 includes a first end point 2131 and a second end point 2132; the first long side 211 includes a third end point 2111 and a fourth end point 2112; the first hypotenuse 212 connects the first end point 2111 and the third end point 2111, and the second hypotenuse 214 connects the second end point 2132 and the fourth end point 2112; the foot of the perpendicular from the first end point 2131 to the first long side 211 is the third foot of the perpendicular C3, the distance from the third foot of the perpendicular C3 to the third end point 2111 is the ninth distance L9, the foot of the perpendicular from the second end point 2132 to the first long side 211 is the fourth foot of the perpendicular C4, the distance from the fourth foot of the perpendicular C4 to the fourth end point 2112 is the tenth distance L10, and the tenth distance L10 is less than or equal to the ninth distance L9. Among them, the length value of the ninth distance L9 is x, and the length value of the distance between the third foot of the perpendicular C3 and the fourth foot of the perpendicular C4 is y, 0 < x ≤ 3 / 16 (x + y). That is, even if the third end point 2111 is offset relative to the third foot of the perpendicular C3, and the fourth end point 2112 is offset relative to the fourth foot of the perpendicular C4, the maximum offset value x of the offset satisfies 0 < x ≤ 3 / 16 (x + y). In this way, it is possible to avoid affecting the display effect due to excessive offsets of the third end point 2111 and the fourth end point 2112.
[0146] Based on the above solution, optionally, 0 < x ≤ 3.8 μm, that is, the third end point 2111 is offset relative to the first foot of the perpendicular C1, but the offset amount of the third end point 2111 relative to the third foot of the perpendicular C3 is greater than 0 and less than or equal to 3.8 μm, and the offset amount of the fourth end point 2112 relative to the fourth foot of the perpendicular C4 is greater than 0 and less than or equal to 3.8 μm. In this way, it is possible to avoid affecting the display effect due to excessive offsets of the third end point 2111 and the fourth end point 2112.
[0147] Based on the above various solutions, optionally, Figure 18 is a schematic structural diagram of another display panel provided by an embodiment of the present application. As Figure 18 shown, at least one of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 has a chamfer.
[0148] In this implementation, at least one of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 is chamfered. For example, the first sub-pixel 11 and the second sub-pixel 12 are chamfered; or, only the third sub-pixel 13 is chamfered; or, not only the light-emitting layers of the first sub-pixel 11 and the second sub-pixel 12 are chamfered, but also the light-emitting layer of the third sub-pixel 13 is chamfered, so that the sub-pixels are arranged compactly, ensuring the display effect of the display panel.
[0149] Optionally, at least one of the first sub-pixel 11 and the second sub-pixel 12 has a chamfer. The shapes of the first sub-pixel 11 and the second sub-pixel 12 both include a pentagon, and the pentagon includes a quasi-right angle and a quasi-obtuse angle.
[0150] The shape of a general sub-pixel is a regular shape, such as a rectangle or a square, etc. In this embodiment, by setting the first sub-pixel 11 and the second sub-pixel 12 as pentagons, and the pentagon includes a quasi-right angle and a quasi-obtuse angle, for example, three quasi-right angles and two quasi-obtuse angles, that is, compared with the shape of the sub-pixel being a rectangle, chamfering the first sub-pixel 11 and the second sub-pixel 12 makes the arrangement of each sub-pixel compact and ensures the display effect of the display panel.
[0151] Optionally, continue to refer to Figure 18 , the pentagon includes at least one right-angle side and an obtuse-angle side, for example, includes four right-angle sides and one obtuse-angle side, and the side lengths of the two right-angle sides adjacent to the obtuse-angle side are the same. In this way, it can ensure that the aperture ratio of the first sub-pixel 11 and the second sub-pixel 12 is relatively large and ensure that the display panel has a good display effect.
[0152] Optionally, continue to refer to Figure 18 , the third sub-pixel 13 has a chamfer. The shape of the third sub-pixel 13 includes a pentagon, and the pentagon includes a quasi-right angle and a quasi-obtuse angle, for example, includes three quasi-right angles and two quasi-obtuse angles. That is, by setting the first sub-pixel 11 and the second sub-pixel 12 as pentagons, compared with the shape of the sub-pixel being a rectangle, chamfering the third sub-pixel 13 makes the arrangement of each sub-pixel compact and ensures the display effect of the display panel.
[0153] Optionally, continue to refer to Figure 18 , the centers of one of the first sub-pixels 11 and one of the second sub-pixels 12 respectively coincide with the endpoints of the second short side 223, and the obtuse-angle side of this first sub-pixel 11 and the obtuse-angle side of this second sub-pixel 12 are opposite to each other; the centers of the other first sub-pixel 11 and the other second sub-pixel 12 respectively coincide with the endpoints of the second long side 221, and the obtuse-angle side of this first sub-pixel 11 and the obtuse-angle side of this second sub-pixel 12 are back to back; the obtuse-angle side of the third sub-pixel 13 faces the second long side 221. In this way, it can ensure that the arrangement of each sub-pixel is compact and ensure that the display panel has a good display effect.
[0154] It should be noted that when a sub-pixel has a chamfer, the center of the sub-pixel is the center of the shape obtained by restoring the sub-pixel with a chamfer to the shape before the chamfering process, and the center of this shape is the center of the sub-pixel after the chamfering process.
[0155] Based on the above various solutions, optionally, Figure 19 is a schematic diagram of a partial structure of another display panel provided by an embodiment of the present application.Figure 20 is a schematic cross-sectional structure diagram corresponding to the display panel, as Figure 19 shown in Figure 19 and Figure 20 shown. The display panel provided by the embodiment of the present application further includes: a substrate 30; a light-shielding layer 50, the light-shielding layer 50 includes a plurality of imaging small holes 51; a light sensor 60, the light sensor 60 is in the vertical direction of the plane where the substrate 30 is located and the vertical projection direction of the imaging small holes 51 in the plane where the substrate 30 is located; the imaging small holes 51 overlap with at least a part of the first long side 211 of the first virtual trapezoid 21; or, the imaging small holes 51 overlap with at least a part of the second long side 221 of the second virtual trapezoid 22, wherein, Figure 16 the description is made by taking the example that the imaging small holes 51 overlap with at least a part of the second long side 221 of the second virtual trapezoid 22. Optionally, it further includes a display layer 40 on one side of the substrate 30, the display layer 40 includes a plurality of light-emitting elements 41; and a pixel circuit layer 70 located between the substrate 30 and the display layer 40, the pixel circuit layer 70 includes a plurality of pixel circuits 71, the pixel circuits 71 are electrically connected to the light-emitting elements 41, and the pixel circuits 71 are used to drive the light-emitting elements 41 electrically connected thereto to emit light. Among them, the sub-pixel further includes the pixel circuit 71.
[0156] It should be noted that the embodiment of the present application does not limit the number of the light-shielding layers 50, Figure 20 and the light-shielding layer 50 including one light-shielding layer 50 is taken as an example for illustration. In other embodiments, the display panel may include two light-shielding layers, etc. Other structures in the display panel may refer to the description of the above embodiments and will not be elaborated here. Among them, the light sensor 60 can be used to implement fingerprint recognition, for example. Specifically, the light-shielding layer 50 is provided with a plurality of imaging small holes 51, and some of the light-emitting elements 41 in the display layer 40 can be reused as fingerprint recognition light sources. After the light generated by the light-emitting elements 41 reaches the contact surface between the fingerprint and the display screen, due to the different reflection degrees of the fingerprint valleys and fingerprint ridges to the light, the reflected light enters the light sensor 60 through the imaging small holes 51, and through the principle of small hole imaging, the fingerprint image is imaged on the light sensor 60 to realize fingerprint recognition.
[0157] In this embodiment, since the centers of the four third sub-pixels 13 surrounding the first sub-pixel 11 form a first virtual trapezoid 21, and the centers of the two first sub-pixels 11 and the two second sub-pixels 12 surrounding the third sub-pixel 13 form a second virtual trapezoid 22, the distance between the two third sub-pixels 13 corresponding to the long side of the first virtual trapezoid 21 becomes larger, and the distance between the first sub-pixel 11 and the second sub-pixel 12 corresponding to the long side of the second virtual trapezoid 22 becomes larger. Therefore, in the embodiment of the present application, the imaging aperture 51 is set to overlap with the first long side 211 of the first virtual trapezoid 21; or, the imaging aperture 51 overlaps with the second long side 221 of the second virtual trapezoid 22, so that there is more space for setting the imaging aperture 51. Furthermore, the aperture of the imaging aperture 51 along the extension direction of the first long side 211 and / or the second long side 221 can be increased. In this way, the light transmission area of the imaging aperture 51 can be increased, the fingerprint recognition signal amount can be increased, the fingerprint recognition time can be shortened, and the adverse effects caused by the diffraction of the imaging aperture 741 can be reduced. Exemplarily, Figure 19 The length of the second long side 221 of the second virtual trapezoid 22 is relatively long, so the imaging aperture 51 is set to overlap with the second long side 221.
[0158] Considering that when the centers of the two first sub-pixels 11 and the two second sub-pixels 12 form the second virtual trapezoid 22, although the distance between the first sub-pixel 11 and the second sub-pixel 12 corresponding to the long side of the second virtual trapezoid 22 will become larger, making more space for setting the imaging aperture 51, the distance between the third sub-pixel 13 and the imaging aperture 51 will become smaller. Also, since the first sub-pixel 11 is turned off during fingerprint unlocking, the distance between the third sub-pixel 13 and the imaging aperture 51 mainly affects the sensitivity of fingerprint unlocking. For example, Figure 21 is a relationship diagram of the light emitted by the third sub-pixel provided in the embodiment of the present application and the distance between the third sub-pixel and the imaging aperture. Refer to Figure 21 As shown in, when the distance between the third sub-pixel 13 and the imaging aperture 51 is closer, the angle between the light emitted by the third sub-pixel 13 and the direction perpendicular to the substrate 30 is smaller. In this way, more stray light enters the imaging aperture 51, interfering with fingerprint unlocking and affecting the sensitivity of fingerprint unlocking.
[0159] Therefore, when the resolution of the display panel is 400 ppi, the distance between the second sub-pixel 12 and the imaging aperture 51 can be set to be greater than 6 μm, and the distance between the third sub-pixel 13 and the imaging aperture 51 can be set to be greater than 6 μm. In this way, it is possible to prevent the light emitted by the second sub-pixel 12 and the third sub-pixel 13 from directly entering the imaging aperture 51 and interfering with fingerprint unlocking.
[0160] In addition, the fingerprint unlocking situation when the first included angle α1 of the first virtual trapezoid 21, the second included angle α2 of the first virtual trapezoid 21, the third included angle β1 of the second virtual trapezoid 22, and the fourth included angle β2 of the second virtual trapezoid 22 are equal and are 90°, 88°, 86°, and 83° was studied as follows:
[0161] Exemplarily, Table 2 shows the fingerprint unlocking situation when the first included angle α1 of the first virtual trapezoid 21, the second included angle α2 of the first virtual trapezoid 21, the third included angle β1 of the second virtual trapezoid 22, and the fourth included angle β2 of the second virtual trapezoid 22 are equal and are 90°, 88°, 86°, and 83°. Figure 22 is the structure of the display panel when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 90° Figure 23 is the structure of the display panel when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 88° Figure 24 is the structure of the display panel when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 86° Figure 25 is the structure of the display panel when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 83°
[0162] It should be noted that the above examples are only illustrative with the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 being equal. However, the present application is not limited to this. In other alternative embodiments, it may also be that the first included angle α1 is equal to the second included angle α2, the third included angle β1 is equal to the fourth included angle β2, but the first included angle α1 is greater than the third included angle β1.

[0165] See Figure 22 、 Figure 23 、 Figure 24 、 Figure 25As well as Table 2, when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 90°, the distance from the first sub-pixel 11 to the imaging aperture 51 is 9.8 μm, the distance from the second sub-pixel 12 to the imaging aperture 51 is 10.9 μm, and the distance from the third sub-pixel 13 to the imaging aperture 51 is 7.4 μm. That is, the distances from the second sub-pixel 12 and the third sub-pixel 13 to the imaging aperture 51 are both greater than 6 μm, which can prevent the light emitted by the second sub-pixel 12 and the third sub-pixel 13 from directly entering the imaging aperture 51. However, the distance between the first sub-pixel 11 and the second sub-pixel 12 is relatively small, resulting in a relatively small area of the imaging aperture 51. For example, the area of the imaging aperture 51 is only 75 μm 2 , thus, the light-transmitting area of the imaging aperture 51 is insufficient, the fingerprint recognition signal amount is small, only 100 ml, which increases the fingerprint unlocking time. For example, the fingerprint unlocking time is 550 ms, and the fingerprint unlocking speed is slow.
[0166] When the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 88°, the distance from the first sub-pixel 11 to the imaging aperture 51 is 10.4 μm, the distance from the second sub-pixel 12 to the imaging aperture 51 is 10.2 μm, and the distance from the third sub-pixel 13 to the imaging aperture 51 is 6.8 μm. It can be seen that when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 become smaller, the distance from the third sub-pixel 13 to the imaging aperture 51 becomes smaller. However, the distances from the third sub-pixel 13 and the second sub-pixel 12 to the imaging aperture 51 are still greater than 6 μm, which can prevent the light emitted by the second sub-pixel 12 and the third sub-pixel 13 from directly entering the imaging aperture 51 and is still within the controllable range. At the same time, the distance between the first sub-pixel 11 and the second sub-pixel 12 increases, so there is more space for setting the imaging aperture 51, that is, the area of the imaging aperture 51 increases. For example, the area of the imaging aperture 51 is 90 μm 2 , compared with the situation where the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 90°, the area of the imaging aperture 51 increases by 15 μm 2 , thus, the fingerprint recognition signal amount increases, for example, it is 120 ml, and the fingerprint recognition time is shortened. For example, the fingerprint unlocking time is 520 ms, and the fingerprint unlocking speed is improved.
[0167] When the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 86°, the distance from the first sub-pixel 11 to the imaging aperture 51 is 11.2 μm, the distance from the second sub-pixel 12 to the imaging aperture 51 is 9.9 μm, and the distance from the third sub-pixel 13 to the imaging aperture 51 is 6.4 μm. From this, it can be seen that when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 continue to become smaller, the distance from the third sub-pixel 13 to the imaging aperture 51 will also become smaller. However, the distances from the third sub-pixel 13 and the second sub-pixel 12 to the imaging aperture 51 are still greater than 6 μm, which can prevent the light rays emitted by the second sub-pixel 12 and the third sub-pixel 13 from directly entering the imaging aperture 51. At the same time, the distance between the first sub-pixel 11 and the second sub-pixel 12 increases, so there is more space for setting the imaging aperture 51, that is, the area of the imaging aperture 51 increases. For example, the area of the imaging aperture 51 is 100 μm 2 , compared with when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 90°, the area of the imaging aperture 51 increases by 25 μm 2 , thus, the fingerprint recognition signal amount increases, for example, it is 138 ml, the fingerprint recognition time is shortened, for example, the fingerprint unlocking time is 490 ms, and the fingerprint unlocking speed is the fastest.
[0168] When the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 83°, the distance from the first sub-pixel 11 to the imaging aperture 51 is 11.8 μm, the distance from the second sub-pixel 12 to the imaging aperture 51 is 9.2 μm, and the distance from the third sub-pixel 13 to the imaging aperture 51 is 5.7 μm. From this, it can be seen that when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 become 83°, although the distance between the first sub-pixel 11 and the second sub-pixel 12 will further increase and the area of the imaging aperture 51 increases, for example, the area of the imaging aperture 51 is 110 μm2, and the fingerprint recognition signal amount increases, for example, it is 110 ml, but the distance from the third sub-pixel 13 to the imaging aperture 51 is 5.7 μm, which is less than 6 μm. The light rays emitted by the third sub-pixel 13 can directly enter the imaging aperture 51, causing interference to the fingerprint unlocking. Thus, the fingerprint unlocking speed decreases instead. For example, the fingerprint unlocking time is 530 ms.
[0169] In summary, when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 90°, the area of the imaging aperture 51 is small, the light-transmitting area of the imaging aperture 51 is insufficient, the fingerprint recognition signal amount is small, and the fingerprint unlocking speed is slow; when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 88°, the distance between the first sub-pixel 11 and the second sub-pixel 12 increases, the area of the imaging aperture 51 increases, the fingerprint recognition signal amount increases, and the fingerprint unlocking speed is improved; when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 86°, the distance between the first sub-pixel 11 and the second sub-pixel 12 further increases, the area of the imaging aperture 51 increases, the fingerprint recognition signal amount increases, and the fingerprint unlocking speed is the fastest; when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 83°, the distance between the first sub-pixel 11 and the second sub-pixel 12 further increases, the area of the imaging aperture 51 increases, but the distance from the third sub-pixel 13 to the imaging aperture 51 is less than 6 μm, and the light emitted by the third sub-pixel 13 can directly enter the imaging aperture 51, interfering with fingerprint unlocking, and the fingerprint unlocking speed decreases instead. It can be seen that when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 86°, the fingerprint unlocking speed is the fastest.
[0170] Based on the above various solutions, optionally, Figure 26 is a partial structural schematic diagram of a display panel provided by an embodiment of the present application, Figure 27 is corresponding to Figure 26 the cross-sectional structural schematic diagram of the corresponding display panel. Refer to Figure 26 and Figure 27, the display panel provided by the embodiment of the present application includes a substrate 30; a support pillar 80 located on the side of the display layer 40 away from the substrate 30, and the distance between the vertical projection of the support pillar 80 on the plane where the substrate 30 is located and the vertical projection of at least a part of the second long side 221 of the second virtual trapezoid 22 on the plane where the substrate 30 is located is a third preset distance. Optionally, the vertical projection of the support pillar 80 on the plane where the substrate 30 is located overlaps with the vertical projection of at least a part of the second long side 221 of the second virtual trapezoid 22 on the plane where the substrate 30 is located. Optionally, it further includes a display layer 40 located on one side of the substrate 30. The display layer 40 includes a pixel defining layer 42 and a plurality of light-emitting elements 41. Each light-emitting element 41 includes: an anode 411, a light-emitting layer 412, and a cathode 413; the pixel defining layer 42 includes a plurality of pixel openings 43, and the plurality of pixel openings 43 are arranged in one-to-one correspondence with the plurality of light-emitting elements 41; and a pixel circuit layer 70 located between the substrate 30 and the display layer 40. The pixel circuit layer 70 includes a plurality of pixel circuits 71. The pixel circuits 71 are electrically connected to the light-emitting elements 41, and the pixel circuits 71 are used to drive the light-emitting elements 41 electrically connected thereto to emit light. Among them, the sub-pixel further includes a pixel circuit 71.
[0171] In the actual manufacturing process, referring to Figure 27 , after forming the pixel opening 43 on the pixel defining layer 42 to expose the anode 411, the corresponding light-emitting material is evaporated in the pixel opening 43 by using a mask plate to form the light-emitting layer 412. Optionally, the light-emitting layers 412 of the light-emitting elements 41 with different light-emitting colors can be evaporated by using different mask plates. In order to avoid the direct contact between the mask plate and the pixel defining layer 42, support pillars 80 need to be provided above the pixel defining layer 42 to support the mask plate.
[0172] In this embodiment, since the centers of two first sub-pixels 11 and two second sub-pixels 12 surrounding the third sub-pixel 13 form a second virtual trapezoid 22, the distance between the first sub-pixel 11 and the second sub-pixel 12 corresponding to the long side of the second virtual trapezoid 22 becomes larger. Therefore, in the embodiment of the present application, by setting the vertical projection of the support pillar 80 on the plane where the substrate 30 is located to overlap with the vertical projection of at least part of the second long side 221 on the plane where the substrate 30 is located, that is, by setting the support pillar 80 above the pixel defining layer 42 between the pixel opening 43 corresponding to the first sub-pixel 11 and the pixel opening 43 corresponding to the second sub-pixel 12 with a larger distance, the setting space of the support pillar 80 can be increased, and the preparation yield can be improved. In addition, for the support pillar 80 of the same size, this embodiment can increase the distance between the support pillar 80 and the pixel opening 43 corresponding to the first sub-pixel 11 and the pixel opening 43 corresponding to the second sub-pixel 12, so as to avoid the support pillar 80 blocking the light emitted by the light-emitting element 41 and reduce color deviation. Therefore, in order to ensure the process yield, it is necessary to consider that the distance between the support pillar 80 and the pixel opening 43 corresponding to the first sub-pixel 11 and the pixel opening 43 corresponding to the second sub-pixel 12 meets the yield design value, and both the second long side 221 and the second short side 223 of the second virtual trapezoid 22 meet the process design value, that is, the minimum distance between the pixel openings of the first sub-pixel 11 and the second sub-pixel 12.
[0173] Exemplarily, Figure 28 It is the structure of the display panel when the first included angle α1 is equal to the second included angle α2, and both are equal to 90°, and the third included angle β1 is equal to the fourth included angle β2, and both are equal to 90°. Figure 29 It is the structure of the display panel when the first included angle α1 is equal to the second included angle α2, and both are equal to 88°, and the third included angle β1 is equal to the fourth included angle β2, and both are equal to 88°. Figure 30 It is the structure of the display panel when the first included angle α1 is equal to the second included angle α2, and both are equal to 86°, and the third included angle β1 is equal to the fourth included angle β2, and both are equal to 86°. Figure 31 It is the structure of the display panel when the first included angle α1 is equal to the second included angle α2, and both are equal to 83°, and the third included angle β1 is equal to the fourth included angle β2, and both are equal to 83°. It should be noted that, Figures 28 - 31 Taking the first included angle α1 being equal to the third included angle β1 as an example for illustration, but it does not limit the present application. In other alternative embodiments, the first included angle α1 may also be greater than the third included angle β1.
[0174] Such as Figures 28 - 31As shown, when the centers of two first sub-pixels 11 and two second sub-pixels 12 form a second virtual trapezoid 22, the second virtual trapezoid 22 includes a second long side 221, a third hypotenuse 222, a second short side 223, and a fourth hypotenuse 224 connected in sequence. The second long side 221 and the third hypotenuse 222 form a third included angle β1, and the second long side 221 and the fourth hypotenuse 224 form a fourth included angle β2. The distance between the vertical projection of the support pillar 80 on the plane where the substrate 30 is located and the vertical projection of at least a part of the second long side 221 on the plane where the substrate 30 is located is set as a third preset distance. Optionally, the vertical projection of the support pillar 80 on the plane where the substrate 30 is located and the vertical projection of at least a part of the second long side 221 on the plane where the substrate 30 is located are set to overlap. At the same time, a plurality of third sub-pixels 13 form a first virtual trapezoid 21. The first virtual trapezoid 21 includes a first long side 211, a first hypotenuse 212, a first short side 213, and a second hypotenuse 214 connected in sequence. The first long side 211 and the first hypotenuse 212 form a first included angle α1, and the first long side 211 and the second hypotenuse 214 form a second included angle α2. A certain preset distance is set between the vertical direction of the support pillar 80 on the plane where the substrate 30 is located and the vertical direction of at least a part of the first short side on the plane where the substrate 30 is located. This preset distance is very small. For example: the vertical direction of the support pillar 80 on the plane where the substrate 30 is located and the vertical direction of at least a part of the first short side on the plane where the substrate 30 is located overlap.
[0175] See Figures 28 - 31 , when the first included angle α1 is equal to the second included angle α2, the third included angle β1 is equal to the fourth included angle β2, and as the first included angle α1 and the third included angle β1 gradually decrease, the second long side 221 of the second virtual trapezoid 22 gradually becomes longer, and the first short side 213 of the first virtual trapezoid 21 becomes shorter accordingly. The distance between the support pillar 80 and the pixel opening 43 corresponding to the first sub-pixel 11 or the pixel opening 43 corresponding to the second sub-pixel 12 on the first short side 213 becomes shorter, and problems such as color deviation or impurities falling into the pixel opening are likely to occur. Therefore, in order to ensure the process yield, in addition to considering the above two design values, the distance between the pixel opening 43 of the third sub-pixel 13 and the support pillar 80 needs to meet the minimum design value.
[0176] Combined with Figures 32 to 34 , where Figure 32 is a relationship diagram of the distance between the pixel openings of the first sub-pixel and the second sub-pixel corresponding to an angle and the second long side provided in an embodiment of the present application, Figure 33 is a relationship diagram of the distance between the angle and the distance from the support pillar to the pixel openings of the first sub-pixel and the second sub-pixel corresponding to the second long side provided in an embodiment of the present application, Figure 34 is a relationship diagram of the distance from the support pillar to the pixel opening of the third sub-pixel within the second trapezoid provided in an embodiment of the present application. Figure 32In this case, the abscissa γ represents the angle, and the ordinate L12 represents the distance between the pixel openings of the first sub-pixel and the second sub-pixel corresponding to the second long side when the first included angle α1 is equal to the second included angle α2, the third included angle β1 is equal to the fourth included angle β2, and they are all equal to 90°, 88°, 86°, and 83°. Figure 33 In this case, the abscissa γ represents the angle, and the ordinate L13 represents the distance from the support column to the pixel openings of the first sub-pixel and the second sub-pixel corresponding to the second long side when the first included angle α1 is equal to the second included angle α2, the third included angle β1 is equal to the fourth included angle β2, and they are all equal to 90°, 88°, 86°, and 83°. Figure 34 In this case, the abscissa γ represents the angle, and the ordinate L14 represents the distance from the support column to the pixel opening of the third sub-pixel within the second trapezoid when the first included angle α1 is equal to the second included angle α2, the third included angle β1 is equal to the fourth included angle β2, and they are all equal to 90°, 88°, 86°, and 83°.
[0177] See Figures 28 - 31 and Figure 32 , as the first included angle α1 and the third included angle β1 both gradually decrease, the distance between the pixel openings 43 of the first sub-pixel 11 and the second sub-pixel 12 gradually decreases until the included angle reaches 83° to achieve the process design value.
[0178] See Figures 28 - 31 and Figure 33 , as the first included angle α1 and the third included angle β1 both gradually decrease, the distance between the support column 80 and the pixel openings 43 corresponding to the first sub-pixel 11 and the pixel openings 43 corresponding to the second sub-pixel 12 gradually becomes longer, and when the included angle is 90°, it is the yield design value.
[0179] See Figures 28 - 31 and Figure 34 , as the first included angle α1 and the third included angle β1 both gradually decrease, the distance between the pixel opening of the third sub-pixel 13 and the support column 80 gradually decreases until the included angle reaches 83° to achieve the minimum design value.
[0180] It can be seen that when the first included angle α1 and the third included angle β1 are both 86°, the distances in these three aspects all exceed the design values, and the process yield is the best.
[0181] It should be noted that the number of support columns 80 can be determined according to the actual process, and the number of support columns 80 is not limited in this embodiment.
[0182] It should be noted that the above examples are only described by taking the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 as being equal. However, the present application is not limited thereto. In other alternative embodiments, it may also be that the first included angle α1 is equal to the second included angle α2, the third included angle β1 is equal to the fourth included angle β2, but the first included angle α1 is greater than the third included angle β1.
[0183] Optionally, continue to refer to Figure 27 , the shortest distance from the support column 80 to the pixel opening 43 is the eleventh distance L11, and the length value of the eleventh distance L11 is greater than or equal to 4.5 μm. In this way, it is possible to prevent debris from falling into the pixel opening 43 after the support column 80 is scratched and affecting the display.
[0184] Based on the above embodiments, optionally, continue to refer to Figure 2 and Figure 3 , both the second long side 221 and the second short side 223 are parallel to the second direction Y; wherein, the second direction Y is the column direction.
[0185] Considering that, during the actual evaporation process, an angle plate is provided on the evaporation machine in the second direction Y, while no angle plate is provided on the evaporation machine in the first direction X. When an angle plate is provided in the second direction Y, during the evaporation of the light-emitting layers corresponding to the sub-pixels arranged in the second direction Y, the evaporation accuracy is relatively high, which can prevent the light-emitting material of the light-emitting layer of the first sub-pixel from falling into the pixel opening corresponding to the second sub-pixel, or prevent the light-emitting material of the light-emitting layer of the second sub-pixel from falling into the pixel opening corresponding to the first sub-pixel; when no angle plate is provided in the first direction X, the evaporation accuracy is relatively low. In this implementation, by increasing the distance between the first sub-pixel 11 and the second sub-pixel 12 in the direction where no angle plate is provided (the first direction X), that is, in the first direction X, the centers of the first sub-pixel 11 and the second sub-pixel 12 respectively overlap with the two end points of the hypotenuse of the second virtual trapezoid 22. Compared with the centers of the first sub-pixel 11 and the second sub-pixel 12 overlapping with the two end points of the short side of the rectangle (such as the diamond arrangement), the distance between the second sub-pixel 12 and the first sub-pixel 11 is increased. Even if no angle plate is provided in the first direction X, the evaporation accuracy can be improved, and it can prevent the light-emitting material of the light-emitting layer of the first sub-pixel 11 from falling into the pixel opening corresponding to the second sub-pixel 12, or prevent the light-emitting material of the light-emitting layer of the second sub-pixel 12 from falling into the pixel opening corresponding to the first sub-pixel 11.
[0186] Optionally, continue to refer to Figure 2 and Figure 3 , both the first long side 211 and the first short side 213 are parallel to the first direction X, and the first direction X is the row direction. In this way, it is possible to ensure that the sub-pixels are arranged compactly and improve the display effect of the display panel.
[0187] Optionally,Figure 35 It is a partial structural schematic diagram of another display panel provided by an embodiment of the present application. Figure 36 It is Figure 35 a cross-sectional view along the BB' direction. Refer to Figure 35 and Figure 36 As shown, the display panel includes: a substrate 30; a pixel circuit layer 70 on one side of the substrate 30, and the pixel circuit layer 70 includes a plurality of pixel circuits 71; a display layer on the side of the pixel circuit layer 70 facing away from the substrate, the display layer includes a plurality of light-emitting elements, the pixel circuit 71 is electrically connected to the light-emitting element, optionally, the pixel circuit 71 is electrically connected to the anode 411 of the light-emitting element; the sub-pixel includes a light-emitting element and the pixel circuit 71; wherein, the pixel circuit 71 is electrically connected to the connection portion 90 through a first via K1, and the connection portion 90 is electrically connected to the anode 411 of the light-emitting element through a second via K2; wherein, the first via K1 and the second via K2 of at least some sub-pixels are arranged along the second direction Y; the second direction Y includes a row direction, or the second direction Y includes a column direction.
[0188] It should be noted that Figure 35 only shows the structures of each pixel circuit 71 and the anode of the light-emitting element, and does not show other structures of the light-emitting element. It should also be noted that Figure 35 the cross-section (indicated by the dotted line) in Figure 35 is only an example. It should also be noted that the second direction Y can be a column direction, and the second direction Y can also be a row direction.
[0189] Exemplarily, continue to refer to Figure 35 and Figure 36 . The pixel circuit 71 corresponding to each sub-pixel, for example, includes a plurality of transistors and at least one capacitor. Figure 35 Taking the pixel circuit 71 including 7 transistors and 1 capacitor as an example for illustration. When the pixel circuit 71 includes 7 transistors and 1 capacitor, optionally, Figure 25 is a circuit diagram of a pixel circuit provided by an embodiment of the present application. As Figure 37 shown, the 7 transistors and 1 capacitor can be, for example, a driving transistor T3, a data writing transistor T2, a threshold compensation transistor T4, a first reset transistor T5, a second reset transistor T7, a first light-emitting control transistor T1, a second light-emitting control transistor T6, and a storage capacitor Cst. Optionally, continue to refer to Figure 23 and Figure 24, the display panel further includes a data signal line Data, a first power supply line PVDD, a second power supply line (not shown in the figure), a first scan line SCAN1, a second scan line SCAN2, a light emission control signal line EMIT, a first reset signal line VREF1, and a second reset signal line VREF1. Among them, the first pole of the first light emission control transistor T1 is electrically connected to the first power supply line PVDD, the first pole of the data writing transistor T2 is electrically connected to the data signal line Data, the gates of the data writing transistor T2 and the threshold compensation transistor T4 can be respectively electrically connected to the second scan line SCAN2, the first pole of the first reset transistor T5 is electrically connected to the first reset signal line VREF1, the first pole of the second reset transistor T7 is electrically connected to the second reset signal line VREF2, the gates of the first reset transistor T5 and the second reset transistor T7 are respectively electrically connected to the first scan line SCAN1, and the gates of the first light emission control transistor T1 and the second light emission control transistor T6 can be respectively electrically connected to the light emission control signal line EMIT. The driving principle of the pixel circuit 71 is similar to that of the 7T1C pixel driving circuit in the prior art, and will not be elaborated here.
[0190] See Figure 35 , the display panel includes a semiconductor layer poly, a first metal layer M1, a second metal layer MC, a third metal layer M2, and a fourth metal layer M3, and an insulating layer located between the metal layers. Exemplarily, the first scan line SCAN1, the second scan line SCAN2, and the light emission control signal line EMIT are located in the first metal layer M1, the first reset signal line VREF1 and the second reset signal line VREF1 are located in the second metal layer MC, the first power supply line PVDD is located in the third metal layer M2, and the data signal line Data is located in the fourth metal layer M3. The first electrode 713 of the second light emission control transistor T6 is electrically connected to the first electrode region of the active layer 711 through a third via K3. Among them, the first electrode 713 can be a source or a drain, and correspondingly, the first electrode region can be a source region or a drain region. This embodiment does not specifically limit. Continue to see Figure 36, the first electrode 713 is electrically connected to the connection portion 90 through the first via K1, and the connection portion 90 is electrically connected to the anode 411 of the light-emitting element through the second via K2. In this way, the pixel circuit 71 provides the current for driving the light-emitting element to emit light. The provision of the connection portion 90 can reduce the depth of the via hole, thereby reducing the difficulty of forming the via hole. The third via K3 penetrates the insulating layer between the semiconductor layer poly and the first metal layer M1 and the insulating layer between the first metal layer M1 and the second metal layer MC, so that the first electrode 713 located on the second metal layer MC is electrically connected to the first electrode region of the active layer 711 through the third via K3; the first via K1 penetrates the insulating layer between the third metal layer M2 and the second metal layer MC, so that the first electrode 713 is electrically connected to the connection portion 90 through the first via K1; the second via K2 penetrates the insulating layer between the third metal layer M2 and the fourth metal layer M3, so that the connection portion 90 is electrically connected to the anode 411 of the light-emitting element through the second via K2.
[0191] In this embodiment, the first via K1 and the second via K2 of at least some of the sub-pixels are arranged along the second direction Y, so that the second via K2 overlaps with the third via K3. Compared with each via hole that needs to occupy a certain area, this embodiment can reduce the occupied area of the via holes, and more space can be vacated to achieve light transmission, thereby improving the light transmittance of the under-screen fingerprint recognition area, increasing the fingerprint signal amount, and improving the unlocking speed.
[0192] It should be noted that the present application does not specifically limit the pixel circuit and the signal lines electrically connected thereto. Figure 35 It is only an example.
[0193] It should be noted that in a layout with a general "diamond" pixel arrangement, multiple first sub-pixels and second sub-pixels form a first virtual square. The first virtual square includes a first upper side, a first lower side, a first left side, and a first right side. Multiple third sub-pixels form a second virtual square. The second virtual square includes a second upper side, a second lower side, a second left side, and a second right side. Among them, the centers of the first sub-pixels and the second sub-pixels located on the first upper side are on the same straight line. Since the pixel opening area of the first sub-pixel is smaller than that of the second sub-pixel, for this reason, the second vias K2 of the first sub-pixels are closer to the emission control signal line EMIT than the second vias K2 of the second sub-pixels, and the distances between the first vias K1 of the first sub-pixels and the first vias K1 of the second sub-pixels and the emission control signal line EMIT are basically the same. Among them, the relative positional relationship between the first vias K1 and the second vias K2 of the first sub-pixels and the second sub-pixels on the first lower side and the layout design are basically the same as those on the first upper side, and will not be elaborated here. At the same time, among the two third sub-pixels on the second upper side, the space between the third sub-pixel located in the first virtual square and the emission control signal line EMIT is very small, and the first via K1 and the second via K2 cannot be set. For this reason, the first via K1 and the second via K2 are set to overlap with the emission control signal line EMIT in the vertical direction of the substrate.
[0194] When changing from a virtual square to a virtual trapezoidal structure, for example, the two first sub-pixels corresponding to the second virtual trapezoid can be moved downward to form a second virtual trapezoid; for example, the two third sub-pixels corresponding to the long side of the first virtual trapezoid can be moved in the direction of the display panel edge, and the two third sub-pixels corresponding to the short side of the first virtual trapezoid can be moved away from the display panel edge to obtain a first virtual trapezoid.
[0195] Continue to refer to Figure 35, as described above, the display panel further includes a light emission control signal line EMIT; since the third sub-pixel located within the second virtual trapezoid marked in the figure moves towards the second long side of the second virtual trapezoid, there is a certain distance between the light emission control signal line EMIT and the left side of the anode 411 corresponding to the third sub-pixel. Compared with the "diamond" pixel arrangement, the second via hole K2 can be moved below the first via hole K1. At the same time, the third sub-pixel is designed with chamfers. In this way, an unobstructed area is formed in this region, and the distance between the light emission control signal line EMIT and the anode 411 corresponding to the third sub-pixel in this region is the first preset distance H1. The advantage of this setting is that more space can be vacated to achieve light transmission, thereby improving the light transmittance of the under-screen fingerprint recognition area and improving the fingerprint recognition effect. In addition, since there is a certain distance between the light emission control signal line EMIT and the left side of the anode 411 corresponding to the third sub-pixel, the first via hole K1 and the second via hole K2 corresponding to the third sub-pixel are arranged along the second direction, so that the second via hole K2 and the third via hole K3 overlap. In this way, the occupied area of the via holes can be further reduced, and then the light transmittance of the under-screen fingerprint recognition area can be improved, the fingerprint signal amount increases, and the unlocking speed is increased. Among them, compared with the third sub-pixel on the second long side of the second virtual trapezoid on the same diagonal line within the second virtual trapezoid marked in the figure, the layout designs of the first via hole K1 and the second via hole K2 of the two are basically the same, and the two moving directions are basically the same, which will not be elaborated here. Optionally, continue to refer to Figure 35 , the first via hole K1 and the second via hole K2 of all sub-pixels are both arranged along the second direction Y, which can make the second via hole K2 of all sub-pixels overlap with the third via hole K3. This implementation can further reduce the occupied area of the via holes, thereby improving the light transmittance of the under-screen fingerprint recognition area, increasing the fingerprint signal amount, and increasing the unlocking speed.
[0196] Optionally, continue to refer to Figure 35 , the vertical projection of the second via hole K2 of the third sub-pixel on the plane of the substrate 30 is located between the vertical projection of the light emission control signal line EMIT and the vertical projection of the anode 411 corresponding to the third sub-pixel on the plane of the substrate 30. Optionally, the vertical projection of the second via hole K2 of the third sub-pixel on the plane of the substrate 30 is located on the side of the first via hole K1 close to the anode 411 corresponding to the third sub-pixel.
[0197] Optionally, continue to refer to Figure 35 and Figure 36, the display panel includes: a substrate 30; a pixel circuit layer 70 on one side of the substrate 30, the pixel circuit layer 70 including a plurality of pixel circuits 71; a display layer on the side of the pixel circuit layer 70 facing away from the substrate, the display layer including a plurality of light-emitting elements, the pixel circuit 71 being electrically connected to the light-emitting element, and the sub-pixel including the light-emitting element and the pixel circuit 71; wherein, the pixel circuit 71 is electrically connected to the connection portion 90 through a first via K1, and the connection portion 90 is electrically connected to the anode 411 of the light-emitting element through a second via K2; the first vias K1 of the second sub-pixel and the first sub-pixel corresponding to the third hypotenuse 222 are located on the eleventh virtual line C11, and the eleventh virtual line C11 extends along the first direction X; the second vias K2 of the second sub-pixel and the first sub-pixel corresponding to the third hypotenuse 222 are located on the twelfth virtual line C12, and the twelfth virtual line C12 extends along the first direction X; the first vias K1 of the second sub-pixel and the first sub-pixel corresponding to the fourth hypotenuse 224 are located on the thirteenth virtual line C13, and the thirteenth virtual line C13 extends along the first direction X; the second vias K2 of the second sub-pixel and the first sub-pixel corresponding to the fourth hypotenuse 224 are located on the fourteenth virtual line C14, and the fourteenth virtual line C14 extends along the first direction X; the first direction X includes a row direction, or the first direction X includes a column direction. Figure 22 The description is made by taking the first direction X as the row direction as an example. The advantage of such a setting is that the via arrangement is simple, which can reduce the manufacturing difficulty.
[0198] Optionally, continue to refer to Figure 35 , the display panel further includes: a reset signal line and a light-emitting control signal line EMIT, wherein the reset signal line can be the two mentioned above, that is, the first reset signal line VREF1 and the second reset signal line VREF2, that is, two reset signal lines correspond to one row of sub-pixels, as Figure 22 shown; in other alternative embodiments, it can also be one, that is, one reset signal line corresponds to one row of sub-pixels.
[0199] Continue to refer to Figure 35 and Figure 36 , the distance between the reset signal line and the light-emitting control signal line EMIT is a second preset distance H2, wherein, Figure 23The description is given by taking the distance between the first reset signal line VREF1 and the emission control signal line EMIT as the second preset distance H2. Optionally, the display panel further includes: a substrate 30; a pixel circuit layer 70 on one side of the substrate 30, the pixel circuit layer 70 including a plurality of pixel circuits 71; a display layer on the side of the pixel circuit layer 70 facing away from the substrate, the display layer including a plurality of light-emitting elements, the pixel circuit 71 being electrically connected to the light-emitting elements; the sub-pixel including the light-emitting element and the pixel circuit 71; wherein, the pixel circuit 71 is electrically connected to the connection portion 90 through the first via K1, and the connection portion 90 is electrically connected to the anode 411 of the light-emitting element through the second via K2; the first via K1 and the second via K2 of the first sub-pixel and the first via K1 and the second via K2 of the second sub-pixel are located between the reset signal line and the emission control signal line EMIT.
[0200] See Figure 35 , the first sub-pixel 11 corresponding to the second short side 223 of the second virtual trapezoid 22 is offset compared to the diamond arrangement, for example Figure 35 In, moving along the -Y direction, when the first sub-pixel moves downward, in order to ensure that the structure in the pixel circuit remains unchanged, that is, the design of the pixel circuit layer remains unchanged, the position of the second via K2 can be moved from the emission control signal line EMIT towards the reset signal line, that is, the first via K1 and the second via K2 of the first sub-pixel and the first via K1 and the second via K2 of the second sub-pixel are located between the reset signal line and the emission control signal line EMIT. In this way, both the design of the pixel circuit can be ensured to remain unchanged, and at the same time, when moving the first via K1, a short circuit between the first via K1 and the first reset signal line VREF1 can be avoided.
[0201] Optionally, both the first via K1 and the second via K2 corresponding to the first sub-pixel are located on the side of the emission control signal line EMIT facing away from the anode 411 corresponding to the first sub-pixel, and both the first via K1 and the second via K2 corresponding to the second sub-pixel are located on the side of the emission control signal line EMIT facing away from the anode 411 corresponding to the second sub-pixel.
[0202] Optionally, continue to refer to Figure 35 , in the first sub-pixel and the second sub-pixel, the second via K2 is located on the side of the first via K1 close to the reset signal line. While ensuring that the original pixel circuit design remains unchanged, the second via K2 and the first via K1 can also be arranged along the second direction Y, reducing the occupied area of the via, thereby increasing the light transmittance of the under-screen fingerprint recognition area, increasing the fingerprint signal amount, and improving the unlocking speed. The specific principle is referred to the above description and will not be elaborated here.
[0203] Based on the same inventive concept, an embodiment of the present application further provides a display panel. The explanations of the same or corresponding terms in this embodiment as those in the above embodiments will not be repeated here. Exemplarily, Figure 38 is a schematic diagram of a partial film layer structure of another display panel provided by an embodiment of the present application. As Figure 38 shown, the display panel further includes: a substrate 30; a display layer 40 located on one side of the substrate 30. The display layer 40 includes a pixel defining layer 42 and a plurality of light-emitting elements. The pixel defining layer 42 includes a plurality of pixel openings 43, and the plurality of pixel openings 43 are arranged in one-to-one correspondence with the plurality of light-emitting elements. The light-emitting element includes a light-emitting layer 412; the ratio of the length of the light-emitting layer 412 in the first direction to the length in the second direction is different from the ratio of the length of the pixel opening 43 corresponding to the light-emitting layer 412 in the first direction to the length in the second direction.
[0204] Figure 39 is a schematic diagram of a partial structure of another display panel provided by an embodiment of the present application. As Figure 39 shown, the display panel 100 includes a plurality of first sub-pixels 11 and a plurality of second sub-pixels 12; the plurality of first sub-pixels and second sub-pixels form a second virtual trapezoid 22. The center of the second sub-pixel 12 is at the first vertex of the second virtual trapezoid 22, and the center of the first sub-pixel 11 is at the second vertex of the second virtual trapezoid 22. The first vertex and the second vertex are alternately and spaced apart; the second virtual trapezoid includes a second long side, a third hypotenuse, a second short side, and a fourth hypotenuse, and the second long side of the second virtual trapezoid extends in the second direction.
[0205] It should be noted that Figure 38 only shows the light-emitting layer 412 of the light-emitting element, that is, the first light-emitting layer 4121 corresponding to the first sub-pixel 11 and the second light-emitting layer 4122 corresponding to the second sub-pixel 12.
[0206] Among them, the first direction is, for example, the row direction, and the second direction is the column direction.
[0207] Figure 40 is a schematic diagram of the principle during the evaporation of the light-emitting layer provided by an embodiment of the present application. As Figure 40 shown, the quadrilateral pointed by arrow 1 is the mask opening corresponding to the mask plate, and the quadrilateral pointed by arrow 2 is the pixel opening. There is a certain distance between the mask plate opening and the pixel opening. This is because when evaporating the light-emitting layer into the pixel opening 43 through the evaporation source and the mask plate, the light-emitting material ejected from the nozzle of the evaporation source is in a scattered state. Also, because there is a certain distance between the mask plate and the pixel defining layer 42, the light-emitting material drifts in the direction from the mask opening of the mask plate to the pixel opening, as Figure 40 shown by the area pointed by arrow 3; at the same time, it drifts in the direction from the pixel opening to the mask opening, as Figure 40The area pointed by arrow 4 in [the figure]. When the light-emitting material drifts through the mask opening of the mask plate in the direction from the mask opening to the pixel opening, if it drifts into the pixel opening, it will cause uneven thickness of the light-emitting layer in the pixel opening, affecting subsequent light emission. When the light-emitting material drifts through the mask opening of the mask plate in the direction from the pixel opening to the mask opening, it may drift into adjacent pixel openings, resulting in color mixing. In addition, when the mask plate is arranged above the pixel opening, there may also be a misalignment deviation. That is to say, considering that the light-emitting material drifts through the mask opening to other areas except the pixel opening and the misalignment deviation, a certain distance (design value) needs to be satisfied between adjacent pixel openings to ensure the yield of evaporating the light-emitting layer.
[0208] Also, because when evaporating the light-emitting layer, an angle plate is provided on the second-direction evaporator, while no angle plate is provided on the first-direction evaporator. When an angle plate is provided in the second direction, since the angle plate can limit the drift of the scattered light-emitting material, the evaporation accuracy is relatively high; when no angle plate is provided in the first direction, the evaporation accuracy is relatively low. If the shape of the pixel opening is square, it will cause the ratio of the lengths of the light-emitting layer 412 in the first direction and the second direction to be greater than the ratio of the lengths of the corresponding pixel opening 43 of the light-emitting layer 412 in the first direction and the second direction. Optionally, the length of the pixel opening 43 in the first direction is equal to the length of the pixel opening 43 in the second direction, and the length of the light-emitting layer 412 in the first direction is greater than the length of the light-emitting layer in the second direction. For example, the ratio of the lengths of the pixel opening 43 in the first direction and the second direction is 1:1, while the ratio of the lengths of the light-emitting layer 412 in the first direction and the second direction is 1.1:1.
[0209] Because, in the first direction, the length of the light-emitting layer 412 in the first direction is greater than the length of the light-emitting layer 412 in the second direction. That is, in the first direction, when evaporating the light-emitting layers 412 corresponding to adjacent sub-pixels, for two adjacent light-emitting layers 412 (the first light-emitting layer 4121 corresponding to the first sub-pixel 11 and the second light-emitting layer 4122 corresponding to the second sub-pixel 12), even the light-emitting material corresponding to the first light-emitting layer 4121 drifts into the pixel opening 43 corresponding to the adjacent second sub-pixel 12, and / or the light-emitting material corresponding to the second light-emitting layer 4122 drifts into the pixel opening 43 corresponding to the adjacent first sub-pixel 11, resulting in color mixing and causing a low yield of evaporating the light-emitting layer. Therefore, in this embodiment, along the first direction, the centers of the adjacent first sub-pixel 11 and the second sub-pixel 12 are located on the hypotenuse of the second virtual trapezoid 22, increasing the distance between the second sub-pixel 12 and the first sub-pixel 11. In this way, even if no angle plate is provided in the first direction, the evaporation accuracy can be improved.
[0210] Optionally, the shape of the light-emitting layer 412 includes a rhombus. Among them, the long axis of the rhombus extends along the first direction, and the short axis of the rhombus extends along the second direction.
[0211] Optionally, Figure 41 is a partial structural schematic diagram of another display panel provided by an embodiment of the present application. As Figure 41 shown, the display panel further includes a plurality of third sub-pixels 13. The plurality of third sub-pixels 13 form a first virtual trapezoid 21. The centers of the plurality of third sub-pixels 13 are respectively located at the vertices of the first virtual trapezoid 21. The first sub-pixel 11 is located inside the first virtual trapezoid 21, and the third sub-pixel 13 is located inside the second virtual trapezoid 22. The first virtual trapezoid 21 includes a first long side 211, a first slant side 212, a first short side 213, and a second slant side 214 connected in sequence. The first long side 211 and the first slant side 212 form a first included angle α1, and the first long side 211 and the second slant side 214 form a second included angle α2. The second long side 221 and the third slant side 222 form a third included angle β1, and the second long side 221 and the fourth slant side 224 form a fourth included angle β2. Among them, the sum of the angles of the first included angle α1 and the second included angle α2 is a first angle, the sum of the angles of the third included angle β1 and the fourth included angle β2 is a second angle, and the difference between the first angle and the second angle is within a first preset range.
[0212] In this implementation, since the sum of the angles of the first included angle α1 and the second included angle α2 is a first angle, the sum of the angles of the third included angle β1 and the fourth included angle β2 is a second angle, and the difference between the first angle and the second angle is within a first preset range. Optionally, the first preset range may be, for example, greater than or equal to 0° and less than or equal to 10°. Exemplarily, the first preset range may be, for example, 0°, 5°, 10°. That is, it can ensure that each sub-pixel has an optimal arrangement, no obvious hollow area, effectively avoid obvious interval gaps, avoid space waste, and ensure the display effect of the display panel 100.
[0213] Among them, the range of the first included angle α1 can satisfy, for example, 82° ≤ α1 ≤ 88°, and can be, for example, 82°, 83°, 84°, 85°, 86°, 87°, 88°, etc.; optionally, the range of α1 satisfies 83° ≤ α1 ≤ 86°, and can be, for example, 83°, 86°, etc.; the first long side 211 and the second hypotenuse 214 form a second included angle α2, among which, the range of the second included angle α2 can satisfy, for example, 82° ≤ α2 ≤ 88°, and can be, for example, 82°, 83°, 84°, 85°, 86°, 87°, 88°, etc.; optionally, the range of α2 satisfies 83° ≤ α2 ≤ 86°, and can be, for example, 83°, 86°, etc.; the second long side 221 and the third hypotenuse 222 form a third included angle β1, among which, the range of the third included angle β1 can satisfy, for example, 82° ≤ β1 ≤ 88°, and can be, for example, 82°, 83°, 84°, 85°, 86°, 87°, 88°, etc.; optionally, the range of β1 satisfies 83° ≤ β1 ≤ 86°, and can be, for example, 83°, 86°, etc.; the second long side 221 and the fourth hypotenuse 224 form a fourth included angle β2, among which, the range of the fourth included angle β2 can satisfy, for example, 82° ≤ β2 ≤ 88°, and can be, for example, 82°, 83°, 84°, 85°, 86°, 87°, 88°, etc.; optionally, the range of β2 satisfies 83° ≤ β2 ≤ 86°, and can be, for example, 83°, 86°, etc. Exemplarily, Table 4 shows the distance between the pixel apertures corresponding to two adjacent sub-pixels when the size of the display area of the display panel in the first direction / the resolution of the display panel = 59.2 μm, and the first included angle α1 of the first virtual trapezoid 21, the second included angle α2 of the first virtual trapezoid 21, the third included angle β1 of the second virtual trapezoid 22, and the fourth included angle β2 of the second virtual trapezoid 22 are equal and are 90°, 88°, 86°, 83°, and 80°.
[0214] Considering that the light-emitting material will drift to other areas except the pixel aperture through the mask aperture and the alignment deviation, a certain distance (design value) needs to be satisfied between adjacent pixel apertures to ensure the yield of the evaporated light-emitting layer. When the resolution of the display panel is fixed, when designing the second virtual trapezoid 22, the third hypotenuse, the fourth hypotenuse, and the second short side need to be considered. Among them, both the third hypotenuse and the fourth hypotenuse are set in the first direction, and the second short side is set in the second direction. In the following description of Table 4, the distance between the pixel apertures of the first sub-pixel and the second sub-pixel in the first direction specifically refers to the lengths of the third hypotenuse and the fourth hypotenuse; the distance between the pixel apertures of the first sub-pixel and the second sub-pixel in the second direction specifically refers to the length of the second short side.
[0215] Since an angle plate is provided in the second direction, the angle plate can limit the dispersion of the scattering light-emitting material, and the evaporation shadow is relatively small; no angle plate is provided in the first direction, and the evaporation shadow is relatively large, resulting in the distance (design value) that needs to be satisfied between adjacent pixel openings in the first direction being greater than the distance (design value) that needs to be satisfied between adjacent pixel openings in the second direction. Thus, when the size of the display area of the display panel in the first direction / the resolution of the display panel = 59.2 μm, the design value in the first direction needs to be greater than or equal to 26 μm, and the design value in the second direction needs to be greater than or equal to 22 μm.
[0216] Table 4
[0217]
[0218] Referring to Table 4, when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 90°, in the first direction, the distance from the pixel opening corresponding to the first sub-pixel to the pixel opening corresponding to the second sub-pixel is 24 μm, and in the second direction, the distance from the pixel opening corresponding to the first sub-pixel to the pixel opening corresponding to the second sub-pixel is 24 μm. That is to say, in the first direction, the distance from the pixel opening corresponding to the first sub-pixel to the pixel opening corresponding to the second sub-pixel, and in the second direction, the distance from the pixel opening corresponding to the first sub-pixel to the pixel opening corresponding to the second sub-pixel both deviate far from the design value, resulting in a low evaporation yield.
[0219] When the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 88°, since the first sub-pixel 11 and the second sub-pixel form a second virtual trapezoid, in the first direction, the distance from the pixel opening corresponding to the first sub-pixel 11 to the pixel opening corresponding to the second sub-pixel 12 increases, corresponding to the two hypotenuses of the second virtual trapezoid, for example, 24.3 μm, while in the second direction, the distance from the pixel opening corresponding to the first sub-pixel to the pixel opening corresponding to the second sub-pixel decreases, corresponding to the second short side of the second virtual trapezoid, for example, 22.94 μm. The distances from the pixel openings corresponding to the first sub-pixel to the pixel openings corresponding to the second sub-pixel in the two directions still have a certain deviation from the design value, resulting in a low evaporation yield.
[0220] When the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 86°, in the first direction, the distance from the pixel opening corresponding to the first sub-pixel to the pixel opening corresponding to the second sub-pixel continues to increase, for example, it is 25.69 μm, while in the second direction, the distance from the pixel opening corresponding to the first sub-pixel to the pixel opening corresponding to the second sub-pixel continues to decrease, for example, it is 21.61 μm. That is to say, in the first direction, the distance from the pixel opening corresponding to the first sub-pixel to the pixel opening corresponding to the second sub-pixel and, in the second direction, the distance from the pixel opening corresponding to the first sub-pixel to the pixel opening corresponding to the second sub-pixel are both near the design value, and the evaporation coating yield is greatly improved. It should be noted that process errors need to be considered when measuring the distance. Therefore, here, being near the design value is used as the standard for improving the evaporation coating yield.
[0221] When the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 83°, due to the further reduction of the second virtual trapezoidal angle, in the first direction, the distance from the pixel opening corresponding to the first sub-pixel to the pixel opening corresponding to the second sub-pixel continues to increase, for example, it is 28.46 μm, while in the second direction, the distance from the pixel opening corresponding to the first sub-pixel to the pixel opening corresponding to the second sub-pixel continues to decrease, for example, it is 19.83 μm. Therefore, when the included angle is 83°, in the first direction, the distance from the pixel opening corresponding to the first sub-pixel to the pixel opening corresponding to the second sub-pixel is near the design value in the first direction, but in the second direction, the distance from the pixel opening corresponding to the first sub-pixel to the pixel opening corresponding to the second sub-pixel is less than the design value in the second direction, and the evaporation coating yield decreases.
[0222] When the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 80°, in the first direction, the distance from the pixel opening corresponding to the first sub-pixel to the pixel opening corresponding to the second sub-pixel continues to increase, for example, it is 29.33 μm, while in the second direction, the distance from the pixel opening corresponding to the first sub-pixel to the pixel opening corresponding to the second sub-pixel continues to decrease, for example, it is 17.03 μm. The distance from the pixel opening corresponding to the first sub-pixel to the pixel opening corresponding to the second sub-pixel in the second direction deviates more from the design value, and the evaporation coating yield further decreases.
[0223] It can be seen from this that when the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 are all 86°, the evaporation coating yield is the best.
[0224] It should be noted that the above examples are only illustrative with the first included angle α1, the second included angle α2, the third included angle β1, and the fourth included angle β2 being equal. However, the present application is not limited thereto. In other alternative embodiments, it may also be that the first included angle α1 is equal to the second included angle α2, the third included angle β1 is equal to the fourth included angle β2, but the first included angle α1 is greater than the third included angle β1.
[0225] Optionally, the first included angle α1 is equal to the second included angle α2, and the third included angle β1 is equal to the fourth included angle β2. That is to say, the first virtual trapezoid 21 is an isosceles trapezoid, and the second virtual trapezoid 22 is also an isosceles trapezoid. In this way, the pixel arrangement is made more uniform and compact, ensuring the display effect of the display panel.
[0226] Optionally, the first included angle α1 is equal to the third included angle β1, that is, the angles of the included angles of the first virtual trapezoid 21 and the second virtual trapezoid 22 are the same, further making the pixel arrangement more uniform and compact, ensuring the display effect of the display panel. Exemplarily, the angle of the first included angle α1 is 86°, the angle of the second included angle α2 is 86°, the angle of the third included angle β1 is 86°, and the angle of the fourth included angle β2 is 86°.
[0227] Optionally, the first included angle α1 is greater than the third included angle β1. In this way, it can ensure that the opening of the third sub-pixel 13 is larger and the display effect is better. Exemplarily, the angle of the first included angle α1 is 86°, the angle of the second included angle α2 is 86°, the angle of the third included angle β1 is 83°, and the angle of the fourth included angle β2 is 83°; Exemplarily, the angle of the first included angle α1 is 88°, the angle of the second included angle α2 is 88°, the angle of the third included angle β1 is 86°, and the angle of the fourth included angle β2 is 86°.
[0228] Optionally, the display panel further includes: a substrate; a light-shielding layer, the light-shielding layer includes a plurality of imaging small holes; a light sensor, there is an overlap between the vertical direction of the light sensor in the plane of the substrate and the vertical direction of the imaging small holes in the plane of the substrate; the imaging small holes overlap with at least part of the first long side of the first virtual trapezoid.
[0229] For a specific explanation, reference can be made to the embodiment of the above imaging small holes, and they have the same beneficial effects. Details are not described herein again.
[0230] Optionally, the display panel includes: a substrate; support columns located on one side of the substrate, there is an overlap between the vertical direction of the support columns in the plane of the substrate and the vertical direction of at least part of the first long side of the first virtual trapezoid in the plane of the substrate.
[0231] For a specific explanation, reference can be made to the embodiment of the above support columns, and they have the same beneficial effects. Details are not described herein again.
[0232] Optionally, the first sub-pixel, the second sub-pixel, and the third sub-pixel are respectively one of a red sub-pixel, a blue sub-pixel, and a green sub-pixel and are different from each other. Exemplarily, the first sub-pixel may be a red sub-pixel, the second sub-pixel may be a blue sub-pixel, and the third sub-pixel may be a green sub-pixel.
[0233] Based on the same inventive concept, an embodiment of the present application further provides a method for manufacturing a display panel. The method for manufacturing the display panel is used to manufacture the display panel in the above embodiment Figure 38 、 39 and the display panel shown in 41. The same parts can be understood with reference to the above explanation of the display panel and will not be repeated hereinafter.
[0234] Figure 42 is a flowchart of a method for manufacturing a display panel provided by an embodiment of the present application. As shown in Figure 42 shown, the method for manufacturing the display panel provided by the embodiment of the present application specifically includes the following steps:
[0235] S110. Provide a substrate and an evaporation source;
[0236] S120. The substrate and the evaporation source move relative to each other in a third direction, and a plurality of first sub-pixels are evaporated on the substrate; the substrate and the evaporation source move relative to each other in the third direction, and a plurality of second sub-pixels are evaporated on the substrate;
[0237] Among them, the plurality of first sub-pixels and the plurality of second sub-pixels form a second virtual trapezoid. The center of the second sub-pixel is at the first vertex of the second virtual trapezoid, and the center of the first sub-pixel is at the second vertex of the second virtual trapezoid. The first vertex and the second vertex alternate and are spaced apart; the second virtual trapezoid includes a second long side, a third hypotenuse, a second short side, and a fourth hypotenuse. The second long side of the second virtual trapezoid extends in a second direction, and the included angle between the third direction and the second direction is within a second preset range. Exemplarily, when evaporating sub-pixels on the substrate, for example, a mask plate is first arranged below the substrate, and the mask plate is set with a mesh. The mask plate includes a plurality of mask openings, and the mask plate openings are correspondingly arranged with the sub-pixels. The light-emitting material ejected by the nozzle of the evaporation source is sprayed onto the substrate from bottom to top; at the same time, the substrate and the evaporation source move relative to each other in the third direction, and a plurality of first sub-pixels are evaporated on the substrate; the substrate and the evaporation source move relative to each other in the third direction, and a plurality of second sub-pixels are evaporated on the substrate. The so-called "relative movement" means moving the substrate or moving the evaporation source. Optionally, move the evaporation source.
[0238] The included angle between the third direction and the second direction is within the second preset range. Optionally, the absolute value of the second preset range is greater than or equal to 0° and less than or equal to 5°. For example, the third direction and the second direction are the same direction. This indicates that when evaporating, the direction of relative movement between the substrate and the evaporation source will not deviate too much from the second direction.
[0239] In this embodiment, since a plurality of first sub-pixels and a plurality of second sub-pixels formed by evaporation deposition constitute a second virtual trapezoid, the center of the second sub-pixel is at the first vertex of the second virtual trapezoid, the center of the first sub-pixel is at the second vertex of the second virtual trapezoid, and the first vertex and the second vertex are alternating and spaced apart; the second virtual trapezoid includes a second long side, a third hypotenuse, a second short side, and a fourth hypotenuse. The second long side of the second virtual trapezoid extends along the second direction, and the hypotenuse of the second virtual trapezoid extends along the first direction, so that the distance between the centers of adjacent first sub-pixels 11 and second sub-pixels 12 is increased. Thus, even if no angle plate is provided in the first direction, the evaporation deposition accuracy can be improved. The specific principle can refer to the foregoing embodiments and will not be elaborated here.
[0240] Optionally, move the evaporation source along the third direction and evaporate deposit a plurality of first sub-pixels on the substrate; move the substrate along the third direction and evaporate deposit a plurality of second sub-pixels on the substrate.
[0241] Optionally, evaporating deposit a plurality of first sub-pixels on the substrate specifically includes: forming a pixel defining layer on the substrate, where the pixel defining layer includes a plurality of pixel openings, and the plurality of pixel openings include a plurality of first pixel openings; evaporating depositing a light-emitting layer, and the light-emitting layer deposited into the first pixel openings forms the first sub-pixels, and the light-emitting layer deposited outside the first pixel openings forms the first shadows.
[0242] For the convenience of understanding, for example, continue to refer to Figure 40 , the first shadow is Figure 40 the areas pointed by arrow 3 and arrow 4 in , that is, the light-emitting layer formed by the areas where the light-emitting material drifts in the direction from the mask opening to the first pixel opening and the areas where the light-emitting material drifts in the direction from the first pixel opening to the mask opening.
[0243] Optionally, evaporating deposit a plurality of second sub-pixels on the substrate specifically includes: forming a pixel defining layer on the substrate, where the pixel defining layer includes a plurality of pixel openings, and the plurality of pixel openings further include a plurality of second pixel openings; evaporating depositing a light-emitting layer, and the light-emitting layer deposited into the second pixel openings forms the second sub-pixels, and the light-emitting layer deposited outside the second pixel openings forms the second shadows.
[0244] For the convenience of understanding, for example, continue to refer to Figure 40 , the first shadow is Figure 40 the areas pointed by arrow 3 and arrow 4 in , that is, the light-emitting layer formed by the areas where the light-emitting material drifts in the direction from the mask opening to the second pixel opening and the areas where the light-emitting material drifts in the direction from the second pixel opening to the mask opening.
[0245] Optionally, the evaporation source includes a plurality of nozzles arranged in a first direction, and angle plates are provided on both sides of the nozzles in a second direction.
[0246] Considering that when evaporating sub-pixels, it is generally evaporated on the display mother board. The length of the display mother board in the first direction is generally less than the length of the display mother board in the second direction. At the same time, the evaporation source moves along a third direction (the included angle with the second direction is within a second preset range). Therefore, the dispersion range of the scattering light-emitting material in this direction will be relatively large. So, in order to limit the dispersion of the scattering light-emitting elements, angle plates are required in the second direction to improve the evaporation accuracy.
[0247] Optionally, the ratio of the length of the light-emitting layer in the first direction to the length in the second direction is greater than the ratio of the length of the pixel opening corresponding to the light-emitting layer in the first direction to the length in the second direction. Optionally, the length of the pixel opening in the first direction is equal to the length of the pixel opening in the second direction, and the length of the light-emitting layer in the first direction is greater than the length of the light-emitting layer in the second direction.
[0248] Since angle plates are provided in the second direction and not in the first direction, the evaporation accuracy in the second direction is higher than that in the first direction. Thus, the shadow in the first direction is greater than the shadow in the second direction. For this reason, the length of the light-emitting layer in the first direction is greater than the length of the light-emitting layer in the second direction.
[0249] Because in the first direction, the length of the light-emitting layer in the first direction is greater than the length of the light-emitting layer in the second direction. That is, in the first direction, when evaporating the light-emitting layers corresponding to adjacent sub-pixels, the light-emitting material corresponding to one light-emitting layer will disperse into the pixel opening corresponding to the second sub-pixel 12 adjacent to the pixel opening corresponding to the adjacent light-emitting layer, and / or, the light-emitting material corresponding to the second light-emitting layer 4122 will disperse into the pixel opening corresponding to the adjacent first sub-pixel 11, resulting in color mixing and causing a low yield of evaporating the light-emitting layer. Therefore, in this embodiment, along the first direction, the centers of the adjacent first sub-pixel 11 and the second sub-pixel 12 are located on the hypotenuse of the second virtual trapezoid 22, increasing the distance between the second sub-pixel 12 and the first sub-pixel 11. Thus, even if no angle plate is provided in the first direction, the evaporation accuracy can still be improved.
[0250] Optionally, the shape of the light-emitting layer includes a rhombus, the long axis of the rhombus extends along the first direction, and the short axis of the rhombus extends along the second direction.
[0251] It can be understood that the shape of the pixel opening is generally square. From the foregoing, the length of the light-emitting layer in the first direction is greater than the length of the light-emitting layer in the second direction. And since the airflows on both sides are uniform during the evaporation of the light-emitting layer, the light-emitting layer not only has a long length in the first direction but also forms a symmetric structure in the second direction, that is, the shape of the obtained light-emitting layer is a rhombus.
[0252] Optionally, the substrate and the evaporation source move relative to each other in a third direction, and a plurality of third sub-pixels are evaporated on the substrate; the plurality of third sub-pixels form a second virtual trapezoid, the centers of the plurality of third sub-pixels are respectively located at the vertices of the second virtual trapezoid, and the first sub-pixel is located inside the second virtual trapezoid, and the third sub-pixel is located inside the first virtual trapezoid;
[0253] The second virtual trapezoid includes a second long side, a third hypotenuse, a second short side, and a fourth hypotenuse connected in sequence; the first long side and the first hypotenuse form a first included angle, and the first long side and the second hypotenuse form a second included angle; the second long side and the third hypotenuse form a third included angle, and the second long side and the fourth hypotenuse form a fourth included angle;

[0255] Optionally, the absolute value of the first preset range is greater than or equal to 0° and less than or equal to 10°.
[0256] Optionally, the first preset range can be, for example, greater than or equal to 0° and less than or equal to 4°; optionally, the first preset range can be, for example, greater than or equal to 0° and less than or equal to 5°; optionally, the first preset range can be, for example, greater than or equal to 0° and less than or equal to 6°. Exemplarily, the first preset range can be 0°, 5°, 10°, that is, it can ensure that each sub-pixel has a better arrangement, no obvious hollow area, effectively avoid obvious interval gaps, avoid space waste, and ensure the display effect of the display panel 100.
