Description

Technical Field

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

[0002] A pixel is the smallest independent representation unit for a display to show an image. Usually, a pixel of a color display needs to have three sub-pixels of red, green, and blue (i.e., r, g, b) primary colors to independently represent various colors in the corresponding color space. A pixel composed of three independently controllable sub-pixels of red, green, and blue is commonly called a real rgb pixel. Currently, the mainstream color display systems all adopt this real rgb pixel format, including the structure of the pixels of a color display and the primary color component signals corresponding to the sub-pixels.

[0003] With the pursuit of high-quality displays and technological progress, the resolution of color displays is continuously increasing. Under certain process capability limitations, the manufacturing difficulty of high-resolution displays increases, severely restricting the display aperture ratio of the displays. For example, in the currently applied AMOLED (Active-matrix organic light-emitting diode) displays for mobile displays, due to the limitations of the mainstream technology for patterning the light-emitting regions of its sub-pixels, i.e., the Fine Metal Mask (FMM) technology, the manufacturing of high-resolution displays is greatly restricted, thus severely restricting the display aperture ratio of the displays. In order to improve the display aperture ratio of high-resolution displays, adopting a more reasonable arrangement of red, green, and blue sub-pixels (sub-pixel arrangement, SPA) in the real rgb pixel format is a reasonable countermeasure. However, some current sub-pixel arrangement schemes for improving the display aperture ratio will bring some display defects to varying degrees. Summary of the Invention

Detailed Embodiments

[0055] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments for a display panel and a display device.

[0056] Based on the inheritance of the system, the stripe sub-pixel arrangement (or simply stripe rgb) adopted by the real rgb pixels of mobile application AMLCD products has become the main sub-pixel arrangement method for the pixels of early mobile display AMOLED real rgb displays. As Figure 1 shown, the stripe rgb pixel is composed of the light-emitting regions of stripe-shaped (such as rectangular) red sub-pixel 3, green sub-pixel 4, and blue sub-pixel 5 with a large aspect ratio. The process direction balance of its light-emitting region manufacturing process is poor: that is, one sub-pixel is distributed per pixel pitch h longitudinally, and three sub-pixels are distributed per pixel pitch h transversely. To avoid color mixing as required by the process margin, the pixel-defined region (Pixeldefine layer, PDL) between adjacent different sub-pixel light-emitting regions will occupy a large proportion of the display area, greatly restricting the improvement of the pixel light-emitting region aperture ratio (the light transmittance of the pixel region for AMLCD) or the physical resolution of the display.

[0057] Among them, the display system is divided into multiple set pixel regions 101, and the multiple set pixel regions 101 are square regions with the same size and shape; the multiple set pixel regions 101 are arranged in a matrix. That is, in order to drive and display an analog image in the display system through a data signal, the display system is divided into multiple set pixel regions 101 (i.e., matrix grid points), and an image is displayed by providing data signals to the multiple set pixel regions 101 for driving. The above pixel pitch h is the side length of the set pixel region 101.

[0058] To achieve a higher pixel aperture ratio or display resolution of the display, an improvement scheme has been proposed in the prior art. As Figure 2 shown, an arrangement is realized in which two sub-pixel light-emitting regions are distributed per pixel pitch h in both the longitudinal and transverse directions. This improvement measure has improved the sub-pixel aperture ratio or the display resolution to a certain extent. However, there are also some problems with this pixel structure. Due to the two-dimensional distribution of the red sub-pixel 3, green sub-pixel 4, and blue sub-pixel 5, it is impossible to ensure that the green sub-pixel 4 is centered. If the green sub-pixel 4 is concentrated on the edge of the display pattern or on one side of the display line, it may cause display effect defects such as edge color deviation (the edge color is greenish).

[0059] As Figure 3As shown, the disclosed technology also proposes to adopt a Delta real rgb (i.e., Delta true red, green, and blue) pixel structure on AMOLED. The sub-pixel arrangement of Delta real rgb has better directional balance, so a higher sub-pixel aperture ratio and physical resolution can be achieved under the same process precision (such as pixel-defined area, PDL width). At the same time, the delta real rgb pixel structure also has relatively superior image performance quality in most scenarios. However, the horizontally adjacent pixel structures of the delta real rgb pixel structure have an up-and-down flipping relationship, and the horizontal translation symmetry of the pixels cannot be ensured. When the delta real rgb pixel structure is applied to a scene with a large number of fine line patterns, at a certain physical resolution, prominent defects such as a certain wavy feeling of the horizontal lines will appear.

[0060] In the above Figures 1 - 3 , the brightness center P' of the pixel composed of the red sub-pixel 3, the green sub-pixel 4, and the blue sub-pixel 5 coincides with the geometric center of the set pixel area 101 (such as Figure 1 and Figure 2 ) or does not coincide (such as Figure 3 ). When the red sub-pixel 3, the green sub-pixel 4, and the blue sub-pixel 5 in the pixel are lit, a visible light spot 2 is formed.

[0061] Regarding the problem that the pixel aperture ratio of the sub-pixel arrangement scheme in the above Figure 1 is relatively low, Figure 2 , Figure 3 although the pixel aperture ratio of the sub-pixel arrangement scheme in Figure 1 is improved, the display defects are more prominent than those in the scheme in Figure 4 and Figure 5 , embodiments of the present invention provide a display panel, as shown in

[0062] , including a plurality of pixels 1, and the plurality of pixels 1 are arranged in a matrix; the row direction of the matrix arrangement is the first direction L1; the pixel 1 includes a first sub-pixel 11, a second sub-pixel 12, and a third sub-pixel 13, and the visible brightness of the second sub-pixel 12, the first sub-pixel 11, and the third sub-pixel 13 decreases in turn under white balance; the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are arranged in sequence along the second direction L2, and the brightness centers P of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are located on the second direction L2; the brightness centers P' of the pixels 1 arranged along the first direction L1 are located on the first direction L1; the included angle θ between the second direction L2 and the first direction L1 is greater than 0° and less than 90°.

[0062] Among them, the pixel 1 matrix is an orthogonal matrix. The first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 have different colors. The visible brightness of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 is the visual perception brightness of sub-pixels of different colors. For example, among the red sub-pixel, the green sub-pixel, and the blue sub-pixel, the visible brightness of the green sub-pixel is the highest, the visible brightness of the red sub-pixel is the second highest, and the visible brightness of the blue sub-pixel is the lowest. The brightness centers P of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are respectively the brightness centers P of each sub-pixel after being processed and calculated (such as weighted calculation, etc.); for sub-pixels with regular geometric shapes, the brightness center P of the sub-pixel is its geometric center; for sub-pixels with irregular geometric shapes, the brightness center P of the sub-pixel is not its geometric center. The brightness center P' of pixel 1 is the brightness center of the visible light spot formed after each sub-pixel within pixel 1 is lit. Similarly, for a visible light spot with a regular geometric shape, the brightness center of the visible light spot is its geometric center; for a visible light spot with an irregular geometric shape, the brightness center of the visible light spot is not its geometric center.

[0063] In this embodiment, the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are organic electroluminescent elements (such as OLED elements). It should be noted that the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 can also be electrically driven quantum dot light-emitting elements (such as QOLED elements), or can also be liquid crystal sub-pixels formed by arranging a liquid crystal layer between a pixel electrode and a common electrode in a liquid crystal display panel.

[0064] In the arrangement mode of each sub-pixel and pixel 1 in this embodiment, relative to Figures 1 - 3 the arrangement mode of each sub-pixel and pixel 1 in [reference], by making the included angle θ between the second direction L2 in which the brightness centers P of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are arranged and the first direction L1 in which the rows of the pixel 1 matrix are arranged be greater than 0° and less than 90°, the aperture ratio of each sub-pixel and pixel 1 can be improved; by arranging the second sub-pixel 12 with the highest visible brightness between the first sub-pixel 11 and the third sub-pixel 13, when the display panel displays the edge of a graphic or a line extending in different directions, it is not easy to cause color deviation at the edge of the image or the line. For example, when displaying an oblique line or the edge of a graphic is an oblique line, the "step" feeling or "jagged" feeling and other display defects at the oblique line or the edge of the oblique line are significantly weakened; by making the brightness center P' of pixel 1 arranged along the first direction L1 be located on the first direction L1, the translational symmetry of pixel 1 along the first direction L1 can be ensured, so that when the display panel displays a large number of fine line patterns, at a certain physical resolution, display defects such as wavy feeling or granular feeling can be avoided, and the display effect of the display panel is improved.

[0065] Optionally, the included angle θ between the second direction L2 and the first direction L1 is greater than 30° and less than 60°.

[0066] Preferably, the included angle θ between the second direction L2 and the first direction L1 is 45°. At this included angle, relative to Figures 1 - 3 the arrangement of each sub-pixel and pixel 1 in [reference], the aperture ratios of each sub-pixel and pixel 1 in the display panel are significantly improved, Figures 1 - 3 and various display defects in [reference] are significantly weakened or improved, thereby significantly enhancing the display effect of the display panel.

[0067] Optionally, as Figure 4 shown, the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are respectively rectangular; a set of opposite sides of the rectangle is perpendicular to the second direction L2. Among them, a set of opposite sides of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 have equal lengths, and the other set of opposite sides have unequal widths.

[0068] Optionally, along the second direction L2, the first spacing distance s1 between any two adjacent ones of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 is equal; the column direction of the matrix arrangement is the third direction L3; along the first direction L1, the second spacing distance s2 between any two adjacent pixels 1 is equal; along the third direction L3, the third spacing distance s3 between any two adjacent pixels 1 is equal; the first spacing distance s1, the second spacing distance s2, and the third spacing distance s3 are equal. Among them, the first spacing distance s1 is the spacing between adjacent sides of two adjacent sub-pixels. The second spacing distance s2 is the spacing between adjacent sides of sub-pixels within two adjacent pixels 1. The third spacing distance s3 is the spacing between adjacent sides of sub-pixels within two adjacent pixels 1. By making the first spacing distance s1, the second spacing distance s2, and the third spacing distance s3 equal, on the one hand, color mixing between adjacent sub-pixels can be avoided, and on the other hand, the aperture ratios of each sub-pixel can be improved.

[0069] Optionally, the first spacing distance s1 is 14 μm or more. Among them, a pixel defining layer (not shown in the figure) is provided within the first spacing distance s1, the second spacing distance s2, and the third spacing distance s3 between adjacent sub-pixels and adjacent pixels 1 to prevent color mixing between adjacent sub-pixels.

[0070] In this embodiment, the display panel has a plurality of set pixel regions 101, and the plurality of set pixel regions 101 are square regions with the same size and shape; a set of opposite sides of the set pixel region 101 that are parallel to each other extend along the first direction L1, and the other set of opposite sides of the set pixel region 101 that are parallel to each other extend along the third direction L3; the plurality of set pixel regions 101 are arranged in a matrix; when the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 of the pixel 1 are lit, a visible light spot 2 is formed; the first sub-pixel 11 and the second sub-pixel 12 are located within the region where the visible light spot 2 is located; the brightness center P' of the pixel 1 is the brightness center of the visible light spot 2; the visible light spots 2 of the plurality of pixels 1 are respectively located within the plurality of set pixel regions 101 in a one-to-one correspondence, and the brightness center of the visible light spot 2 coincides with the geometric center of the set pixel region 101 where it is located. In this embodiment, the brightness center of the visible light spot 2 is its geometric center.

[0071] Optionally, along the first direction L1, the distance a between the brightness centers of the visible light spots 2 of any two adjacent pixels 1 is equal to the side length of the set pixel region 101 (i.e., the pixel pitch h); along the third direction L3, the distance between the brightness centers of the visible light spots 2 of any two adjacent pixels 1 is equal to the side length of the set pixel region 101 (i.e., the pixel pitch h).

[0072] Among them, according to the arrangement of each sub-pixel in the pixel 1, a physical pixel region 102 (i.e., the actual pixel region) is formed. The physical pixel region 102 is rectangular in shape. A set of opposite sides of the physical pixel region 102 extend along the second direction L2, and the width side of the physical pixel region 102 extends in a direction perpendicular to the second direction L2. The pixel 1 is located within the physical pixel region 102. The area of the physical pixel region 102 is equal to the area of the set pixel region 101. With the above arrangement of the pixel 1 and the sub-pixels in this embodiment, on the one hand, along the first direction L1, two sub-pixels are distributed per pixel pitch h; along the third direction L3, two sub-pixels are distributed per pixel pitch h. This direction balance of the sub-pixel arrangement is better, so that a higher sub-pixel aperture ratio and physical resolution can be achieved under the same process precision (such as the width of the pixel definition layer). On the other hand, since the shape of the visible light spot 2 formed when the pixel 1 with the above sub-pixel arrangement is lit has weaker directionality (that is, based on the brightness center of the visible light spot 2, the radial scales of the visible light spot 2 are closer to each other), therefore, Figure 4 the sub-pixel arrangement in this embodiment is more suitable for the performance of line patterns or other graphic edges extending in different directions, and is not likely to cause color deviation phenomena at the image or line edges. For example, when displaying an oblique line or the edge of a graphic is an oblique line, it significantly weakens the "step" or "jagged" sense and other display defects at the oblique line or the edge of the oblique line; at the same time, it can also ensure the translational symmetry of the pixel 1 along the first direction L1, so that when the display panel displays a large number of fine line patterns, at a certain physical resolution, it can avoid display defects such as waviness or granularity, and improves the display effect of the display panel.

[0073] Optionally, the first sub-pixel 11 includes a red sub-pixel; the second sub-pixel 12 includes a green sub-pixel; the third sub-pixel 13 includes a blue sub-pixel. Under the same driving signal, the visible brightness of the green sub-pixel is the highest, the visible brightness of the red sub-pixel is the second highest, and the blue sub-pixel is basically invisible.

[0074] Optionally, the area ratio of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 is 1:1.3:1.7. Since the lifetimes of OLED light-emitting elements of different colors are different, by setting the area ratio of the red sub-pixel, the green sub-pixel, and the blue sub-pixel to 1:1.3:1.7, it is possible to ensure that the lifetimes of these three color sub-pixels are the same, thereby ensuring the display lifetime and display quality of the display panel.

[0075] As shown in Table 1, for Figure 1 、 Figure 2 and this embodiment Figure 4 the display panels with sub-pixel arrangements are respectively simulated and designed for resolutions of 326 ppi, 260 ppi, and 220 ppi. The relevant aperture ratio simulation results are shown in Table 1:

[0076]

[0077] Table 1

[0078] As can be seen from the above Table 1, the sub-pixel arrangement in this embodiment Figure 4 significantly improves the aperture ratio of the display panel.

[0079] Optionally, as Figure 6 shown, the shape and arrangement of the sub-pixels in the display panel can also be: the second sub-pixel 12 is in an approximate rectangular shape; the first sub-pixel 11 and the third sub-pixel 13 are in rectangular shapes respectively; a set of opposite sides of the rectangle is perpendicular to the second direction L2; along the second direction L2, two corners on the side of the second sub-pixel 12 facing away from the first sub-pixel 11 form a linear chamfer or an arc chamfer. With such a setting, compared with the sub-pixel shape and arrangement in Figure 4 , it can further make the directivity of the shape of the visible light spot 2 formed when the pixel 1 with the above sub-pixel arrangement is lit weaker (that is, based on the brightness center of the visible light spot 2, the radial scales of the visible light spot 2 are closer to each other). Therefore, the sub-pixel arrangement in this embodiment Figure 6 can further adapt to the performance of line patterns or other graphic edges extending in different directions, and is not likely to cause color deviation phenomena at the edges of images or lines. For example, when displaying a slant line or the edge of a graphic is a slant line, it significantly weakens the "step" feeling or "jagged" feeling and other display defects at the slant line or the slant line edge; however, compared with the sub-pixel shape and arrangement in Figure 4 , the aperture ratio of the second sub-pixel 12 will be slightly lost.

[0080] Optionally, as shown in Figure 7 , the shapes and arrangements of the sub-pixels in the display panel can also be: the first sub-pixel 11 and the second sub-pixel 12 are respectively approximately rectangular; the third sub-pixel 13 is rectangular; a set of opposite sides of the rectangle is perpendicular to the second direction L2; along the second direction L2, two corners on the side of the second sub-pixel 12 away from the first sub-pixel 11 form a linear chamfer or an arc chamfer; along the second direction L2, two corners on the side of the first sub-pixel 11 away from the second sub-pixel 12 form a linear chamfer or an arc chamfer. With such a setting, compared with the sub-pixel shapes and arrangements in Figure 6 , the directivity of the shape of the visible light spot 2 formed when the pixel 1 with the above sub-pixel arrangement is lit can be further weakened (i.e., based on the brightness center of the visible light spot 2, the radial scales of the visible light spot 2 are closer to each other). Therefore, in this embodiment Figure 7 , the sub-pixel arrangement can further adapt to the performance of line patterns or other graphic edges extending in different directions, and it is not easy to cause color deviation at the image or line edges. For example, when displaying an oblique line or the edge of a graphic is an oblique line, the "step" feeling or "jagged" feeling and other display defects at the oblique line or the edge of the oblique line are significantly reduced; however, compared with the sub-pixel shapes and arrangements in Figure 6 , the aperture ratio of the second sub-pixel 12 will be lost to some extent.

[0081] Optionally, as shown in Figure 8 , the shapes and arrangements of the sub-pixels in the display panel can also be: the first sub-pixel 11 and the second sub-pixel 12 are respectively trapezoidal; the third sub-pixel 13 is rectangular; the trapezoidal shape is formed by chamfering a rectangular shape with its long side perpendicular to the second direction L2; the bottom side of the trapezoid is perpendicular to the second direction L2; and along the second direction L2, the shorter bottom side of the second sub-pixel 12 is farther from the first sub-pixel 11 than its longer bottom side, and the shorter bottom side of the first sub-pixel 11 is farther from the second sub-pixel 12 than its longer bottom side; a set of opposite sides of the rectangle is perpendicular to the second direction L2. With such a setting, compared with the sub-pixel shapes and arrangements in Figure 7 , the directivity of the shape of the visible light spot 2 formed when the pixel 1 with the above sub-pixel arrangement is lit can be further weakened (i.e., based on the brightness center of the visible light spot 2, the radial scales of the visible light spot 2 are closer to each other). Therefore, in this embodiment Figure 8 , the sub-pixel arrangement can further adapt to the performance of line patterns or other graphic edges extending in different directions, and it is not easy to cause color deviation at the image or line edges. For example, when displaying an oblique line or the edge of a graphic is an oblique line, the "step" feeling or "jagged" feeling and other display defects at the oblique line or the edge of the oblique line are significantly reduced; however, compared with the sub-pixel shapes and arrangements in Figure 7 , the aperture ratios of the first sub-pixel 11 and the second sub-pixel 12 will be further lost.

[0082] Optionally, as Figure 9 shown, the shape and arrangement of sub-pixels in the display panel may also be: the first sub-pixel 11 and the second sub-pixel 12 are respectively pentagonal in shape; the third sub-pixel 13 is rectangular in shape; the pentagonal shape is formed by chamfering a rectangular shape with a short side perpendicular to the second direction L2; the first side 6 of the pentagon is perpendicular to the second direction L2; the second side 7 and the third side 8 adjacent to the first side 6 are parallel to the second direction L2; the fourth side 9 and the fifth side 10 of the pentagon are adjacent and intersect with the second direction L2; and along the second direction L2, the fourth side 9 and the fifth side 10 of the second sub-pixel 12 are farther from the first sub-pixel 11 than its first side 6, and the fourth side 9 and the fifth side 10 of the first sub-pixel 11 are farther from the second sub-pixel 12 than its first side 6; a set of opposite sides of the rectangle is perpendicular to the second direction L2. With such a setting, compared with Figure 7 the sub-pixel shape and arrangement in, it can further make the directionality of the shape of the visible light spot 2 formed when the pixel 1 with the above sub-pixel arrangement is lit weaker (that is, taking the brightness center of the visible light spot 2 as a reference, the radial scales of each part of the visible light spot 2 are closer), so in this embodiment Figure 9 the sub-pixel arrangement in can further adapt to the performance of line graphics or other graphic edges extending in different directions, and is not likely to cause color deviation at the image or line edge. For example, when displaying an oblique line or the edge of a graphic is an oblique line, it significantly weakens the "step" feeling or "jagged" feeling and other display defects of the oblique line or the oblique line edge; but relative to Figure 7 the sub-pixel shape and arrangement in, the aperture ratios of the first sub-pixel 11 and the second sub-pixel 12 will be further lost.

[0083] For the display panel provided by the embodiment of the present invention, compared with the arrangement manners of each sub-pixel and pixel in the prior art, by making the included angle θ between the second direction in which the brightness centers of the first sub-pixel, the second sub-pixel and the third sub-pixel are arranged and the first direction in which the pixel matrix rows are arranged greater than 0°, the aperture ratios of each sub-pixel and the pixel can be improved; by arranging the second sub-pixel with the highest visible brightness between the first sub-pixel and the third sub-pixel, when the display panel displays a graphic edge or a line extending in different directions, it is not likely to cause color deviation at the image or line edge. For example, when displaying an oblique line or the edge of a graphic is an oblique line, it significantly weakens the "step" feeling or "jagged" feeling and other display defects of the oblique line or the oblique line edge; by making the brightness centers of the pixels arranged along the first direction located on the first direction, it can ensure the translational symmetry of the pixels along the first direction, so that when the display panel displays a large number of fine line patterns, at a certain physical resolution, display defects such as waviness or graininess can be avoided, and the display effect of the display panel is improved.

[0085] By adopting the display panel in any of the above embodiments, not only the display aperture ratio of the display device is improved, but also some display defects caused after improving the display aperture ratio are improved or avoided, and the display effect of the display device is enhanced.
