All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in this application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
It should be understood that although the terms first, second, third, etc. may be used to describe the sub-pixel rows in embodiments of the present invention, these sub-pixel rows should not be limited to these terms. These terms are only used to distinguish each of the different rows of subpixels from each other. For example, a first subpixel row may also be referred to as a second subpixel row, and similarly, a second subpixel row may also be referred to as a first subpixel row, without departing from the scope of embodiments of the present invention.
In the process of realizing the invention, the inventor researches and discovers that the image edge is easy to generate a jaggy phenomenon when the oblique image is displayed on the display panel designed based on the prior several sub-pixel arrangement modes. Specifically, as shown in fig. 1 and fig. 2, fig. 1 is a schematic diagram of sub-pixel arrangement of a display panel provided by the related art, in which sub-pixels are arranged in a standard RGB manner, fig. 2 is a schematic diagram of a display including an oblique straight edge in an ideal case, when displaying a display including an oblique straight edge as shown in fig. 2, due to limitation of the pixel arrangement in the scheme of fig. 1, a jaggy edge as shown in fig. 3 is displayed, and fig. 3 is a schematic diagram of a display including an oblique straight edge in a practical case, which can be seen, in which the jaggy phenomenon is obvious.
In view of the above, an embodiment of the present invention provides a display panel, as shown in fig. 4, fig. 4 is a schematic diagram of sub-pixel arrangement of the display panel according to the embodiment of the present invention, where the display panel includes a plurality of sub-pixel row groups 1 repeatedly arranged along a first direction h1.
The sub-pixel row group 1 includes a first sub-pixel row 11 and a second sub-pixel row 12 arranged in the first direction h1. Each of the first and second sub-pixel rows 11 and 12 includes a plurality of green sub-pixels G arranged at equal intervals along the second direction h 2. Wherein the first direction h1 intersects the second direction h 2.
Distance d between two adjacent green sub-pixels G in the first sub-pixel row 11 1 Distance d from two adjacent green sub-pixels G in the second sub-pixel row 12 2 Equal or approximately equal. In the embodiments of the present invention, the distance between two adjacent sub-pixels represents the distance between the geometric centers of the two adjacent sub-pixels unless otherwise specified. In addition, d 1 And d 2 Approximately equal represents d 1 And d 2 There is a difference within the allowable range of process errors.
With continued reference to FIG. 4, in an embodiment of the present invention, the first subpixel row 11 and the second subpixel row 12 are a distance d along the first direction h1 3 Less than the distance d between two adjacent green sub-pixels G in the first sub-pixel row 11 1 . And, the distance between the two nearest green sub-pixels in the first sub-pixel row 11 and the second sub-pixel row 12 is d 1 . That is, in the embodiment of the present invention, the first subpixel row 11 and the second subpixel row 12 are disposed offset in the first direction h1. Specifically, the first subpixel row 11 is shifted d along the second direction h2 1 The distance/2 can then be aligned with the second subpixel row 12 in the first direction h1. So configured, the connection line between two adjacent green sub-pixels G in the first sub-pixel row 11 and the geometric center of the nearest green sub-pixel G in the second sub-pixel row 12 can form an equilateral triangle. The connection line between two adjacent green sub-pixels G in the second sub-pixel row 12 and the geometric center of the nearest green sub-pixel G in the first sub-pixel row 11 can form an equilateral triangle.
As can be seen from fig. 4, the separation distance in the second subpixel row 12 is 2d 1 The two green sub-pixels G of (2) and the four green sub-pixels G in the two first sub-pixel rows 11 which are positioned at two sides of the second sub-pixel row 12 and adjacent to the second sub-pixel row 12 are connected to form a line with a side length d 1 The six green sub-pixels G are respectively located at six vertex positions of the regular hexagon. Specifically, taking the regular hexagon 2 shown in fig. 4 as an example, the vertex of the regular hexagon 2 isTwo of the six green sub-pixels G are located in the second sub-pixel row 12. Two of the other four green sub-pixels G at the vertices of the regular hexagon 2 are located in a first sub-pixel row 11 adjacent to the above-described second sub-pixel row 12 and located on one side of the second sub-pixel row 12, and the other two are located in a first sub-pixel row 11 adjacent to the above-described second sub-pixel row 12 and located on the other side of the second sub-pixel row 12. The green sub-pixel G located at the center of the regular hexagon 2 is located in the second sub-pixel row 12. For convenience of explanation, the green sub-pixel G located at the center of the regular hexagon is hereinafter referred to as a first green sub-pixel 10.
In the embodiment of the present invention, as shown in fig. 4, in the oblique directions z1 and z2 indicated by the dash-dot lines, the arrangement of the green sub-pixels G is the same as the arrangement of the first sub-pixel row 11 and the second sub-pixel row 12 arranged in the second direction h 2. Therefore, according to the embodiment of the invention, the green sub-pixels G are arranged according to the regular hexagon shape rule, and compared with a strip structure formed by arranging the green sub-pixels G along a single direction, the arrangement symmetry of the green sub-pixels G can be greatly improved, and the arrangement difference between different directions is reduced. Because the sensitivity degree of human eyes to light rays with different colors is different, and the human eyes are most sensitive to green light, by adopting the setting mode of the embodiment of the invention, the jaggy feeling when the oblique pattern pictures extending along different directions are displayed can be reduced, and the display effect of the display panel when the oblique pattern pictures extending along a plurality of different directions are displayed can be improved.
In addition, according to the embodiment of the invention, the green sub-pixels G are arranged according to the regular hexagon shape rule, as shown in fig. 4, and the translational symmetry of the regular hexagon can be utilized, so that the green sub-pixels G at different positions in the display panel are all arranged according to the regular hexagon arrangement rule.
In order to realize full-color display of the display panel, the display panel provided by the embodiment of the invention is further provided with a red sub-pixel R and a blue sub-pixel B. On the basis of arranging the green sub-pixels G in a regular hexagon as shown in fig. 4, the embodiment of the present invention divides the red sub-pixels R and the blue sub-pixels B at spaced positions of the green sub-pixels G. Specifically, as shown in fig. 5, fig. 5 is a schematic diagram of sub-pixel arrangement of another display panel according to an embodiment of the present invention, where red sub-pixels R may be disposed in both the first sub-pixel row 11 and the second sub-pixel row 12. In the first subpixel row 11 and the second subpixel row 12, the red subpixels R are each located between two adjacent green subpixels G. And, three green sub-pixels G are included between two adjacent red sub-pixels R, and the green sub-pixel G located in the middle of the three green sub-pixels G is the first green sub-pixel 10. Any one of the red sub-pixels R in the first sub-pixel row 11 and the first green sub-pixels 10 in the second sub-pixel row 12 are arranged along the first direction h1.
With continued reference to fig. 5, embodiments of the present invention also provide a third sub-pixel row 13 and a fourth sub-pixel row 14 in sub-pixel row group 1. Along the first direction, the third subpixel row 13 is located between the first subpixel row 11 and the second subpixel row 12, and the fourth subpixel row 14 is located on a side of the second subpixel row 12 away from the third subpixel row 13. The third subpixel row 13 and the fourth subpixel row 14 each include red subpixels R and blue subpixels B alternately arranged at equal intervals in the second direction h 2; and, a distance d between the adjacent red and blue sub-pixels R and B in the third sub-pixel row 13 4 Distance d between red and blue sub-pixels B adjacent in the fourth sub-pixel row 14 5 Equal or approximately equal. The red sub-pixels R of the third sub-pixel row 13 and the blue sub-pixels B of the fourth sub-pixel row 14 are arranged along the first direction h1, i.e., the line connecting the geometric centers of the two is parallel or approximately parallel to the first direction h1. Distance d between adjacent red and blue sub-pixels R and B in the third sub-pixel row 13 4 Distance d from two adjacent green sub-pixels G in the first sub-pixel row 11 1 The method meets the following conditions: d, d 1 ＜d 4 ＜2d 1 . The connection lines of the first green sub-pixel 10 in the first sub-pixel row 11 and the two first green sub-pixels 10 closest to each other in the second sub-pixel row 12 pass through the adjacent red sub-pixel R and blue sub-pixel B in the third sub-pixel row 13, respectively.
For any regular hexagon surrounded by the green sub-pixels G, the red sub-pixels R and the blue sub-pixels B are arranged in the above manner, so that the red sub-pixels R and the blue sub-pixels B can correspond to six sides of the regular hexagon and are correspondingly arranged at the gaps between two adjacent green sub-pixels G. When the display panel is driven, the embodiment of the invention can adopt a sub-pixel rendering (Sub Pixel Rendering, SPR) algorithm, so that the area shown by the regular hexagon 2 shown in fig. 5 is a pixel unit, or the area shown by the quadrangle 3 surrounded by the black solid line shown in fig. 5 is a pixel unit, wherein the sub-pixels at the positions of the edges and the vertexes of the regular hexagon 2 or the quadrangle 3 are shared by a plurality of pixel units nearby in the display process, thereby enabling the display panel to have visual resolution higher than physical resolution, and further improving the sensory resolution under the condition that the physical resolution of the display panel is unchanged.
Currently, in order to fabricate a display panel having high resolution, it is required to reduce the size of sub-pixels and/or the distance between adjacent sub-pixels. However, the reduction of the sub-pixel size and the distance between sub-pixels requires a high display panel manufacturing process. Therefore, if the resolution of the display panel is increased by reducing the size of the sub-pixels and/or reducing the distance between adjacent sub-pixels, it will result in an increase in difficulty and cost of the manufacturing process of the display panel. For example, when manufacturing an OLED display panel with high resolution, the process difficulty of manufacturing the display panel with high resolution is great and the manufacturing cost is high due to the limitation of the process accuracy of the Fine Metal Mask (FMM) technology for manufacturing the organic light emitting layer. In the embodiment of the invention, the size or the interval of the sub-pixels in the display panel is not required to be adjusted, namely, the physical resolution of the display panel is not required to be adjusted, and on the basis of not increasing the process difficulty and the manufacturing cost of the display panel, the higher sensory resolution can be realized by adopting the pixel arrangement mode and matching with a corresponding SPR algorithm.
In addition, as shown in fig. 5, in the embodiment of the invention, by adopting the above arrangement manner, the red sub-pixels R may be disposed on four sides of one regular hexagon, and the blue sub-pixels B may be disposed on the other two sides, so that the number ratio of the red sub-pixels R, the green sub-pixels G, and the blue sub-pixels B in one pixel unit is R: g: b=2:3:1. According to the embodiment of the invention, when the SPR algorithm is adopted to drive the display of the display panel, the sharpening degree of the edge position of the display image can be improved on the basis of eliminating the oblique saw-tooth problem of the display image, and the definition of the edge position of the display image is ensured.
In addition, by adopting the above arrangement, the connection line between the first green sub-pixel 10 and the two blue sub-pixels B can be located at the symmetry axis of the regular hexagon to which the three belong, so as to improve the color mixing uniformity of the sub-pixels with different colors in the display panel.
It should be noted that, in addition to using a plurality of sub-pixels located in the area where the regular hexagon or the quadrangle shown in fig. 5 is located as one pixel unit, in the embodiment of the present invention, other SPR algorithms may be used to make a plurality of sub-pixels located in other areas as one pixel unit, which is not limited in the embodiment of the present invention.
Exemplary, as shown in FIG. 5, the distance d between the red subpixel R in the first subpixel row 11 and the nearest red subpixel R in the third subpixel row 13 6 Distance d between red subpixel R of 11 in the first subpixel row and blue subpixel B closest to third subpixel row 7 The method meets the following conditions: d, d 6 ＝d 7 . The distance between the green sub-pixel G in the first sub-pixel row 11 and the nearest red sub-pixel R in the third sub-pixel row 13 is d 1 /2. Similarly, the green sub-pixel G in the first sub-pixel row 11 is at a distance d from the nearest blue sub-pixel B in the third sub-pixel row 13 1 /2. The arrangement is such that the red and blue sub-pixels R and B are located at the midpoint of the sides of the regular hexagon surrounded by the green sub-pixel G, so as to reduce the influence of the introduction of the red and blue sub-pixels R and B on the symmetry of the regular hexagon.
As shown in fig. 6, fig. 6 is a schematic diagram illustrating arrangement of sub-pixels of a display panel according to another embodiment of the present invention, wherein the red sub-pixel R and the blue sub-pixel B are in a shape of a long stripe. That is, the red subpixel R and the blue subpixel B are each formed to have a size in one direction significantly larger than that in the other direction. Herein, the elongated shape includes a rectangular shape, an elliptical shape, or other irregular shape.
When the organic light emitting layer of the sub-pixel is formed by a process such as vapor deposition, a certain diffusion of the organic light emitting layer may occur outside the target region, and the diffusion region is called a shadow (shadow) region. According to the embodiment of the invention, the red sub-pixel R and the blue sub-pixel B are designed to be long, and compared with a block structure with the sizes in all directions being consistent, the distance between the edges of two adjacent sub-pixels can be increased by reasonably setting the extending directions of the red sub-pixel R and the blue sub-pixel B under the condition of a certain area, so that the problem of interference between the adjacent sub-pixels caused by the shadow effect can be avoided, and the display quality is ensured.
For example, the embodiment of the present invention may set the extending directions of the red and blue sub-pixels R and B to be different from the extending directions of the sides of the regular hexagon in which they are located. Taking fig. 6 as an example, in the first subpixel row 11 and the second subpixel row 12, the embodiment of the present invention may set the red subpixels R to extend in the first direction h1. In the third subpixel row 13, the red subpixel R may be disposed to extend along the third direction h3, the blue subpixel B may be disposed to extend along the fourth direction h4, the third direction h3 is different from the fourth direction h4, and the acute included angle α1 between the third direction h3 and the first direction h1 is equal to the acute included angle α2 between the fourth direction h4 and the first direction h1. In the fourth sub-pixel row h4, the red sub-pixel R is set to extend in the fifth direction h5, the blue sub-pixel B is set to extend in the sixth direction h6, the fifth direction h5 is different from the sixth direction h6, and an angle α3 between the fifth direction h5 and the first direction h1, and an angle α4 between the sixth direction h6 and the first direction h1 are equal. In this embodiment of the present invention, for the above regular hexagon surrounded by the green sub-pixels G, the shortest distance between the red sub-pixel R or the blue sub-pixel B on each side of the regular hexagon and the edge of the green sub-pixel G adjacent thereto is ensured, so that interference between adjacent sub-pixels can be avoided.
Optionally, as shown in fig. 7, fig. 7 is a schematic diagram of sub-pixel arrangement of another display panel according to an embodiment of the present invention, where the third direction h3 and the fifth direction h5 may be set to be the same, and the fourth direction h4 and the sixth direction h6 may be set to be the same, so as to further improve symmetry of a regular hexagon surrounded by the red sub-pixel R, the green sub-pixel G and the blue sub-pixel B.
For example, as shown in fig. 7, the above α1 may be set to 60 °, so that the red, green and blue sub-pixels R, G and B located on the sides of the regular hexagon may be regarded as having rotational symmetry with the first green sub-pixel 10 as a center. That is, in the same regular hexagon, the red sub-pixel R located in the third sub-pixel row 13 is rotated by 60 ° around the first green sub-pixel 10 to overlap the red sub-pixel R located in the first sub-pixel row 11, and the rotation 120 ° overlaps the blue sub-pixel B located in the third sub-pixel row 13.
With continued reference to fig. 7, in an embodiment of the present invention, the red and blue sub-pixels R and B may be designed to have elliptical shapes, and at least a portion of the green sub-pixel G may be designed to have a circular shape. Further, as shown in fig. 7, the outer edges of the red and blue sub-pixels R and B belonging to the same regular hexagon around the first green sub-pixel 10 (the edge distant from the first green sub-pixel 10) may be made to be co-rounded, that is, there may be one virtual circle passing through the outer edges of the red and blue sub-pixels R and B belonging to the same regular hexagon around the first green sub-pixel 10. Similarly, the geometric centers of the red and blue sub-pixels R and B belonging to the same regular hexagon around the first green sub-pixel 10 may be also co-rounded, i.e., there is another virtual circle of smaller radius passing through the geometric centers of the red and blue sub-pixels R and B belonging to the same regular hexagon around the first green sub-pixel 10. Similarly, the inner edges of the red and blue sub-pixels R and B belonging to the same regular hexagon around the first green sub-pixel 10 (the edge close to the first green sub-pixel 10) may also be co-rounded, i.e., there is another virtual circle of smaller radius passing through the inner edges of the red and blue sub-pixels R and B belonging to the same regular hexagon around the first green sub-pixel 10. The three virtual circles (three circles on the left side of the screen in fig. 7) with different radii are concentric circles, and the center of the circle is the center of the first green sub-pixel 10.
In addition, with continued reference to fig. 7, there are virtual circles (two circles on the right side of the screen in fig. 7) passing through the surrounding six green sub-pixels G around the green sub-pixel G other than the first green sub-pixel 10.
Optionally, as shown in fig. 8, fig. 8 is a schematic view of a sub-pixel arrangement of another display panel according to an embodiment of the present invention, where each of the red sub-pixel R and the blue sub-pixel B includes two end portions 41 and an intermediate portion 42 between the two end portions 41. In the red subpixel R, the arrangement direction of the end portions 41 and the intermediate portions 42, and the extending direction of the intermediate portions 42 are the same as the extending direction of the red subpixel R. In the blue subpixel B, the arrangement direction of the end portion 41 and the intermediate portion 42, and the extending direction of the intermediate portion 42 are the same as the extending direction of the blue subpixel B.
Specifically, as shown in fig. 8, in the first subpixel row 11: the extending direction of the red sub-pixel R is a first direction h1; the end portions 41 and the intermediate portions 42 of the red sub-pixel R are arranged in the first direction h1, that is, the arrangement direction of the end portions 41 and the intermediate portions 42 of the red sub-pixel R is the first direction h1; the extending direction of the intermediate portion is a first direction h1. In the third subpixel row 13 and the fourth subpixel row 14: the extending directions of the red sub-pixels R are all the third direction h3; the end portions 41 and the intermediate portions 42 of the red sub-pixel R are each arranged along the third direction h3, that is, the arrangement direction of the end portions 41 and the intermediate portions 42 of the red sub-pixel R is the third direction h3; the extending direction of the intermediate portion 42 is the third direction h3. The extending directions of the blue sub-pixels B are all in a fourth direction h4; the end portions 41 and the intermediate portions 42 of the blue sub-pixel B are arranged along the fourth direction h4, that is, the arrangement direction of the end portions 41 and the intermediate portions 42 of the blue sub-pixel B is the fourth direction h4; the extending direction of the intermediate portion 42 is the fourth direction h4.
As shown in fig. 8, in the red subpixel R and the blue subpixel B provided in the embodiment of the present invention, the width of the middle portion 42 is smaller than the width of the end portion 41, wherein the width directions of the red subpixel R and the blue subpixel B are perpendicular to the respective extending directions. And the connecting lines of two adjacent green sub-pixels G pass through the middle part of the red sub-pixel R or the blue sub-pixel B on a plurality of different edges included in the regular hexagon. For example, in the first sub-pixel row 11, the connection line of two adjacent green sub-pixels G passes through the middle portion 42 of the red sub-pixel R. The distance between the edges of two adjacent sub-pixels with different colors on the edges of the regular hexagon can be further increased, so that the problem of interference between the adjacent sub-pixels caused by a shadow effect is further avoided, and the display quality is ensured.
By way of example, the areas of the red sub-pixel R and the blue sub-pixel B may be set to be larger than the area of the green sub-pixel G in the embodiment of the invention, so as to balance the difference of the life of the three organic light emitting layers with different colors, improve the brightness uniformity of the light rays with different colors in the display panel, and avoid color shift.
Optionally, as shown in fig. 9, fig. 9 is a schematic view of a subpixel arrangement of another display panel according to an embodiment of the present invention, where a part of green subpixels G are circular in shape; the shape of the partial green sub-pixel G is triangular.
Specifically, in the same first sub-pixel row 11, the green sub-pixels G located on both sides of the red sub-pixel R are triangular, and the extending direction of the side of the triangle close to the red sub-pixel R is the same as the extending direction of the red sub-pixel R. By the arrangement, on the premise of ensuring the area of the green sub-pixel G, the distance between the edges of the adjacent sub-pixels with different colors on the edges of the regular hexagon can be increased, so that the problem of interference between the adjacent sub-pixels caused by a shadow effect is further avoided, and the display quality is ensured.
The embodiment of the invention also provides a display device, as shown in fig. 10, fig. 10 is a schematic diagram of the display device according to the embodiment of the invention, where the display device includes the display panel 100 described above. The specific structure of the display panel 100 is described in detail in the above embodiments, and will not be described here again. Of course, the display device shown in fig. 10 is only a schematic illustration, and the display device may be any electronic apparatus having a display function, such as a mobile phone, a tablet computer, a notebook computer, an electronic book, or a television.
According to the display device provided by the embodiment of the invention, the green sub-pixels can be arranged according to the regular hexagon shape rule, and compared with a strip-shaped structure formed by arranging the green sub-pixels along a single direction, the arrangement symmetry of the green sub-pixels can be greatly improved, and the arrangement difference between different directions is reduced. Because the sensitivity degree of human eyes to light rays with different colors is different, and the human eyes are most sensitive to green light, by adopting the setting mode of the embodiment of the invention, the jaggy feeling when the oblique pattern pictures extending along different directions are displayed can be reduced, and the display effect of the display panel when the oblique pattern pictures extending along a plurality of different directions are displayed can be improved.
In addition, the green sub-pixels are arranged according to the regular hexagon shape rule, and the translational symmetry of the regular hexagon can be utilized, so that the green sub-pixels at different positions in the display panel are arranged according to the regular hexagon arrangement rule.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather to enable any modification, equivalent replacement, improvement or the like to be made within the spirit and principles of the invention.
