Description

Display panel and display device

Technical Field

The invention belongs to the technical field of display, and particularly relates to a display panel and a display device.

Background

A pixel is the smallest independent unit of the display to display an image, and generally, a color display pixel needs to have red, green and blue (r, g, b) three-primary-color sub-pixels to independently represent various colors of a corresponding color space. A pixel composed of three sub-pixels of red, green and blue that can be controlled independently is commonly called a true red green blue (real rgb) pixel. Currently, the mainstream color display systems all adopt the real rgb pixel format, including the structure of the color display pixels and the primary color component signals corresponding to the sub-pixels.

With the pursuit of high quality displays and technological advances, the resolution of color displays is constantly increasing. Under the limitation of certain process capability, the manufacturing difficulty of the high-resolution display is increased, and the display aperture ratio of the display is severely limited. For example, in an Active-matrix organic light-emitting diode (AMOLED) display currently used for mobile display, due to the limitation of a mainstream patterning technology of a sub-pixel light-emitting region, namely a Fine Metal vapor deposition (FMM) Mask technology, the manufacturing of a high-resolution display is greatly restricted, so that the display aperture ratio of the display is severely restricted. In order to improve the display aperture ratio of the high-resolution display, under the true red, green and blue pixel format, the adoption of more reasonable sub-pixel arrangement (SPA) of red, green and blue is a reasonable coping method, but some display defects are brought to different degrees by some current sub-pixel arrangement schemes for improving the display aperture ratio.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, a display panel and a display device of the present invention are described in further detail below with reference to the accompanying drawings and the detailed description.

Based on the inheritance of the system, the strip sub-pixel arrangement (or simply strip rgb) adopted by the real red green blue (real rgb) pixel of the mobile application AMLCD product becomes the main sub-pixel arrangement mode of the pixels of the early-stage mobile display AMOLED real red green blue (real rgb) display. As shown in fig. 1, the stripe rgb pixel is composed of stripe (e.g. rectangular) red sub-pixel 3, green sub-pixel 4, and blue sub-pixel 5 light emitting regions with large length-width ratio, and the light emitting regions have poor direction uniformity in the manufacturing process: that is, one sub-pixel is distributed per pixel pitch h in the longitudinal direction, and three sub-pixels are distributed per pixel pitch h in the transverse direction. In order to avoid color mixing, the Pixel definition area (PDL) between adjacent sub-Pixel light emitting areas occupies a large proportion of the display area, which greatly restricts the improvement of the Pixel light emitting area aperture ratio (AMLCD is the light transmittance of the Pixel area) or the physical resolution of the display.

The display system is divided into a plurality of setting pixel areas 101, and the setting pixel areas 101 are square areas with the same size and shape; the plurality of set pixel regions 101 are arranged in a matrix, that is, in order to drive and display an analog image by data signals in a display system, the display system is divided into the plurality of set pixel regions 101 (i.e., matrix grid points), and the display of an image is realized by driving by supplying the data signals to the plurality of set pixel regions 101. The pixel pitch h is set to a side length of the pixel region 101.

In order to achieve a higher aperture ratio or display resolution of the display, an improvement is proposed in the prior art, as shown in fig. 2, in which an arrangement of two sub-pixel light emitting regions distributed per pixel pitch h is implemented in both the vertical and horizontal directions. This improvement strategy increases the sub-pixel aperture ratio or display resolution to some extent. However, the pixel structure has some problems, because the red sub-pixel 3, the green sub-pixel 4, and the blue sub-pixel 5 are distributed in two dimensions, the green sub-pixel 4 cannot be ensured to be arranged in the middle, and if the green sub-pixel 4 is concentrated at the edge of the display pattern or at one side of the display line, a display effect defect such as edge color bias (edge color bias green) may be caused.

As shown in fig. 3, it is also proposed in the prior art to adopt a Delta real rgb (i.e. Delta true red green blue) pixel structure on the AMOLED. The directional balance of the Delta real rgb sub-pixel arrangement is good, so that the higher sub-pixel aperture ratio and physical resolution can be realized under the same process precision (such as pixel limited area, PDL width). Meanwhile, the delta real rgb pixel structure has relatively excellent image representation quality under most scenes. However, the delta real rgb pixel structure has the horizontal adjacent pixel structure in the up-down flip relationship, and the horizontal translation symmetry of the pixel cannot be ensured. When the delta real rgb pixel structure is applied to a scene with a large number of fine line patterns, the transverse lines can show a certain wave feeling and other outstanding defects under a certain physical resolution.

In fig. 1 to 3, the luminance center P' of the pixel constituted by 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 region 101 (see fig. 1 and 2) or does not coincide with the geometric center of the set pixel region 101 (see fig. 3). The red sub-pixel 3, the green sub-pixel 4 and the blue sub-pixel 5 form a visible light spot 2 when being lighted.

In view of the above-mentioned problem that the pixel aperture ratio of the sub-pixel arrangement scheme in fig. 1 is relatively low, and the problem that the pixel aperture ratio of the sub-pixel arrangement scheme in fig. 2 and 3 is improved, but the display defects are more prominent than those of the scheme in fig. 1, an embodiment of the present invention provides a display panel, as shown in fig. 4 and 5, including a plurality of pixels 1, where the plurality of pixels 1 are arranged in a matrix; the row direction of the matrix arrangement is a 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 luminance of the second sub-pixel 12, the first sub-pixel 11, and the third sub-pixel 13 decreases in order in white balance; the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are sequentially arranged along the second direction L2, and the luminance centers P of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are located in the second direction L2; the luminance centers P' of the pixels 1 arranged in the first direction L1 are located in the first direction L1; the second direction L2 forms an included angle θ with the first direction L1 larger than 0 ° and smaller than 90 °.

Wherein the pixel 1 matrix is an orthogonal matrix. The first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 are different in color. The visible brightness of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 is the visually perceived brightness of the sub-pixels with 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, and the visible brightness of the red sub-pixel is the next to the blue sub-pixel is the lowest. The luminance centers P of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are the luminance centers P of the sub-pixels after being processed and calculated (such as weighting calculation, etc.); for a sub-pixel having a regular geometry, the luminance center P of the sub-pixel is its geometric center; for sub-pixels with irregular geometry, the luminance center P of the sub-pixel is not its geometric center. The brightness center P' of the pixel 1 is the brightness center of the visible light spot formed after each sub-pixel in the pixel 1 is lighted. Similarly, for a visible light spot with a regular geometric shape, the brightness center of the visible light spot is the geometric center thereof; for visible spots with irregular geometry, the center of brightness of the visible spot is not its geometric center.

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

In this embodiment, compared to the arrangement of each sub-pixel and each pixel 1 in fig. 1 to 3, the arrangement of each sub-pixel and each pixel 1 in this embodiment can improve the aperture ratio of each sub-pixel and each pixel 1 by making an included angle θ between the second direction L2 in which the luminance 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 pixels 1 are arranged in a matrix row greater than 0 ° and less than 90 °; by arranging the second sub-pixels 12 with the highest visible brightness between the first sub-pixels 11 and the third sub-pixels 13, the display panel is not easy to cause color shift phenomenon of images or lines when displaying graph edges or lines extending in different directions, for example, when displaying oblique lines or graph edges as oblique lines, display defects such as 'step' feeling or 'saw tooth' feeling of oblique lines or oblique line edges are obviously weakened; the luminance centers P' of the pixels 1 arranged along the first direction L1 are positioned in the first direction L1, so that the translational symmetry of the pixels 1 along the first direction L1 can be ensured, display defects such as wavy feeling or granular feeling can be avoided under certain physical resolution when the display panel displays a large number of fine line patterns, and the display effect of the display panel is improved.

Optionally, the second direction L2 forms an included angle θ with the first direction L1 that is greater than 30 ° and less than 60 °.

Preferably, the second direction L2 forms an angle θ of 45 ° with the first direction L1. Under the angle of the included angle, compared with the arrangement mode of each sub-pixel and the pixel 1 in fig. 1 to 3, the aperture opening ratio of each sub-pixel and the pixel 1 in the display panel is obviously improved, and various display defects in fig. 1 to 3 are obviously weakened or improved, so that the display effect of the display panel is obviously improved.

Alternatively, as shown in fig. 4, the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are respectively rectangular in shape; a set of opposite sides of the rectangle is perpendicular to the second direction L2. The lengths of a pair of opposite sides of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 are equal, and the widths of the other pair of opposite sides are different.

Optionally, along the second direction L2, the first spacing distances s1 between any adjacent two of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are equal; the column direction of the matrix arrangement is a third direction L3; along the first direction L1, the second spacing distances s2 between any two adjacent pixels 1 are equal; along the third direction L3, the third spacing distances s3 between any two adjacent pixels 1 are equal; the first spacing distance s1, the second spacing distance s2, and the third spacing distance s3 are equal. Wherein, the first spacing distance s1 is the distance between the adjacent edges of two adjacent sub-pixels. The second spacing distance s2 is the spacing between the adjacent sides of the sub-pixels in two adjacent pixels 1. The third spacing distance s3 is the spacing between the adjacent edges of the sub-pixels in two adjacent pixels 1. By making the first spacing distance s1, the second spacing distance s2, and the third spacing distance s3 equal, color mixing between adjacent sub-pixels can be avoided, and the aperture ratio of each sub-pixel can be increased.

Alternatively, the first separation distance s1 is 14 μm or more. In which a pixel defining layer (not shown) is disposed within the first spacing distance s1, the second spacing distance s2, and the third spacing distance s3 between the adjacent sub-pixels and the adjacent pixel 1 to prevent color mixing between the adjacent sub-pixels.

In this embodiment, the display panel has a plurality of setting pixel regions 101, and the setting pixel regions 101 are square regions with the same size and shape; a set of opposite sides of the pixel region 101, which are parallel to each other, are set to extend in the first direction L1, and another set of opposite sides of the pixel region 101, which are parallel to each other, are set to extend in the third direction L3; a plurality of set pixel regions 101 are arranged in a matrix; the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 of the pixel 1 form a visible light spot 2 when being lighted; the first sub-pixel 11 and the second sub-pixel 12 are located in the area 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 pixels 1 are respectively located in the setting pixel areas 101 in a one-to-one correspondence manner, and the brightness center of the visible light spots 2 coincides with the geometric center of the setting pixel area 101 where the visible light spots are located. In this embodiment, the center of brightness of the visible light spot 2 is the geometric center thereof.

Alternatively, in the first direction L1, the distance a between the luminance 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); in the third direction L3, the distance between the luminance 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).

Wherein the physical pixel region 102 (i.e., the actual pixel region) is formed according to the arrangement of the sub-pixels within the pixel 1, the physical pixel region 102 has a rectangular shape, a set of opposite sides of the physical pixel region 102 extend along the second direction L2, and a wide side of the physical pixel region 102 extends along a direction perpendicular to the second direction L2. Pixel 1 is located within physical pixel area 102. The area of the physical pixel region 102 is equal to the area of the set pixel region 101. In the above arrangement of the pixel 1 and the sub-pixels in this embodiment, on one hand, two sub-pixels are distributed per pixel pitch h along the first direction L1; two sub-pixels are distributed in each pixel pitch h along the third direction L3, and the directional balance of the arrangement of the sub-pixels is better, so that higher sub-pixel aperture ratio and physical resolution can be realized under the same process precision (such as the width of a pixel defining layer). On the other hand, since the pixel 1 having the above-mentioned sub-pixel arrangement has a weaker directivity of the shape of the visible light spot 2 formed when it is turned on (i.e. the radial dimensions of the visible light spot 2 are closer to each other with respect to the center of the brightness of the visible light spot 2), the sub-pixel arrangement in fig. 4 of this embodiment is more suitable for the representation of the line pattern or other pattern edges extending in different directions, and is less likely to cause color shift phenomenon of the image or line edges, for example, when the oblique line is displayed or the pattern edges are oblique lines, the display defects such as "step" feeling or "jaggy" feeling of the oblique line or oblique line edges are significantly weakened; meanwhile, the translational symmetry of the pixel 1 along the first direction L1 can be ensured, so that when the display panel displays a large number of fine line patterns, display flaws such as wave feeling or particle feeling are avoided under a certain physical resolution, and the display effect of the display panel is improved.

Optionally, the first sub-pixel 11 comprises a red sub-pixel; the second sub-pixel 12 comprises a green sub-pixel; the third sub-pixel 13 comprises 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, and the blue sub-pixel is basically invisible.

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. Due to the fact that the service lives of the OLED light-emitting elements of different colors are different, the area ratio of the red sub-pixel to the green sub-pixel to the blue sub-pixel is set to be 1:1.3:1.7, the service lives of the sub-pixels of the three colors can be guaranteed to be consistent, and therefore the display service life and the display quality of the display panel are guaranteed.

As shown in table 1, the display panels with subpixel arrangements in fig. 1, 2 and 4 of the present embodiment are designed to be simulated corresponding to resolutions of 326ppi, 260ppi and 220ppi, and the simulation results of the related aperture ratios refer to table 1:

TABLE 1

As can be seen from table 1 above, the arrangement of the sub-pixels in fig. 4 of this embodiment significantly improves the aperture ratio of the display panel.

Optionally, as shown in fig. 6, the shape and arrangement of the sub-pixels in the display panel may also be: the second sub-pixel 12 is approximately rectangular in shape; the first subpixel 11 and the third subpixel 13 are respectively rectangular in shape; a set of opposite sides of the rectangle are perpendicular to the second direction L2; along the second direction L2, two corners of the second sub-pixel 12 on the side facing away from the first sub-pixel 11 form a straight-line type chamfer or an arc-line type chamfer. With such an arrangement, compared with the shape and arrangement of the sub-pixels in fig. 4, the directionality of the shape of the visible light spot 2 formed when the pixel 1 having the above sub-pixel arrangement is turned on can be further weakened (i.e., the radial dimensions of the visible light spot 2 are closer based on the brightness center of the visible light spot 2), so the sub-pixel arrangement in fig. 6 of this embodiment can further adapt to the representation of the line pattern or other pattern edges extending in different directions, and is not easy to cause the color shift phenomenon of the image or line edges, for example, when oblique lines are displayed or the pattern edges are oblique lines, the display defects such as "step" feeling or "saw tooth" feeling of the oblique lines or oblique line edges are significantly weakened; however, the aperture ratio of the second sub-pixel 12 is slightly lost compared to the shape and arrangement of the sub-pixels in fig. 4.

Optionally, as shown in fig. 7, the shape and arrangement of the sub-pixels in the display panel may also be: the first sub-pixel 11 and the second sub-pixel 12 are each approximately rectangular in shape; the third sub-pixel 13 is rectangular in shape; a set of opposite sides of the rectangle are perpendicular to the second direction L2; along the second direction L2, two corners of the second sub-pixel 12 on the side away from the first sub-pixel 11 form a linear chamfer or an arc chamfer; along the second direction L2, two corners of the first sub-pixel 11 on the side facing away from the second sub-pixel 12 form a straight-line type chamfer or an arc-line type chamfer. With such an arrangement, compared with the shape and arrangement of the sub-pixels in fig. 6, the directionality of the shape of the visible light spot 2 formed when the pixel 1 having the above sub-pixel arrangement is turned on can be further weakened (i.e. the radial dimensions of the visible light spot 2 are closer based on the brightness center of the visible light spot 2), so that the sub-pixel arrangement in fig. 7 of this embodiment can further adapt to the representation of the line or other graphic edges extending in different directions, and is not easy to cause the color shift phenomenon of the image or line edge, for example, when the oblique line is displayed or the graphic edge is the oblique line, the display defects such as the "step" feeling or the "saw tooth" feeling of the oblique line or oblique line edge are significantly weakened; however, the aperture ratio of the second sub-pixel 12 is lost compared to the shape and arrangement of the sub-pixels in fig. 6.

Optionally, as shown in fig. 8, the shape and arrangement of the sub-pixels in the display panel may also be: the first sub-pixel 11 and the second sub-pixel 12 are respectively in a trapezoidal shape; the third sub-pixel 13 is rectangular in shape; the trapezoidal shape is formed by chamfering a rectangular shape whose long side is perpendicular to the second direction L2; the base of the trapezoid is perpendicular to the second direction L2; and along the second direction L2, the shorter base of the second sub-pixel 12 is farther from the first sub-pixel 11 than the longer base thereof, and the shorter base of the first sub-pixel 11 is farther from the second sub-pixel 12 than the longer base thereof; a set of opposite sides of the rectangle is perpendicular to the second direction L2. With such an arrangement, compared with the shape and arrangement of the sub-pixels in fig. 7, the directionality of the shape of the visible light spot 2 formed when the pixel 1 having the above sub-pixel arrangement is turned on can be further weakened (i.e. the radial dimensions of the visible light spot 2 are closer based on the brightness center of the visible light spot 2), so the sub-pixel arrangement in fig. 8 of this embodiment can further adapt to the representation of the line pattern or other pattern edges extending in different directions, and is not easy to cause the color shift phenomenon of the image or line edges, for example, when the oblique lines are displayed or the pattern edges are oblique lines, the display defects such as "step" feeling or "saw tooth" feeling of the oblique lines or oblique line edges are significantly weakened; however, the aperture ratios of the first sub-pixel 11 and the second sub-pixel 12 are further lost compared to the shape and arrangement of the sub-pixels in fig. 7.

Optionally, as shown in fig. 9, the shape and arrangement of the sub-pixels in the display panel may also be: the first sub-pixel 11 and the second sub-pixel 12 are respectively in a pentagonal shape; the third sub-pixel 13 is rectangular in shape; the pentagonal shape is formed by chamfering a rectangular shape whose short side is perpendicular to the second direction L2; the first side 6 of the pentagon is perpendicular to the second direction L2; the second and third sides 7, 8 adjacent to the first side 6 are parallel to the second direction L2; the fourth 9 and fifth 10 sides of the pentagon are contiguous and intersect 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 the first side 6 thereof, 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 the first side 6 thereof; a set of opposite sides of the rectangle is perpendicular to the second direction L2. With such an arrangement, compared with the shape and arrangement of the sub-pixels in fig. 7, the directionality of the shape of the visible light spot 2 formed when the pixel 1 having the above sub-pixel arrangement is turned on can be further weakened (i.e. the radial dimensions of the visible light spot 2 are closer based on the brightness center of the visible light spot 2), so the sub-pixel arrangement in fig. 9 of this embodiment can further adapt to the representation of the line pattern or other pattern edges extending in different directions, and is not easy to cause the color shift phenomenon of the image or line edges, for example, when the oblique lines are displayed or the pattern edges are oblique lines, the display defects such as "step" feeling or "saw tooth" feeling of the oblique lines or oblique line edges are significantly weakened; however, the aperture ratios of the first sub-pixel 11 and the second sub-pixel 12 are further lost compared to the shape and arrangement of the sub-pixels in fig. 7.

Compared with the arrangement mode of each sub-pixel and each pixel in the prior art, the display panel provided by the embodiment of the invention can improve the aperture opening ratio of each sub-pixel and each pixel by enabling the second direction of the brightness center arrangement of the first sub-pixel, the second sub-pixel and the third sub-pixel and the first direction of the pixel matrix row arrangement to form an included angle theta larger than 0 degree; the second sub-pixels with the highest visible brightness are arranged between the first sub-pixels and the third sub-pixels, so that when the display panel displays the graph edge or lines extending in different directions, the color shift phenomenon of the graph or the line edge is not easy to cause, for example, when oblique lines are displayed or the graph edge is oblique lines, display defects such as 'step' feeling or 'saw tooth' feeling of the oblique lines or the oblique line edge are obviously weakened; the luminance center through making the pixel of arranging along the first direction is located the first direction, can ensure the translation symmetry of pixel along the first direction to make this display panel avoid appearing the display flaw such as wave sense or granular sensation under certain physical resolution when showing a large amount of fine line patterns, promoted this display panel's display effect.
