Organic Light Emitting Diode (OLED) display technology is considered as the next generation of the most promising new flat panel display technology. At present, the OLED display panel generally adopts three colors of red (R), blue (B) and green (G) pixels to be arranged in a fixed structure, but the existing pixel arrangement structure still has a problem that the display effect of the OLED display device is affected due to the characteristics of the organic light emitting material.
Disclosure of Invention
Accordingly, there is a need for a pixel arrangement structure that solves the problem of the display effect of the OLED display device being affected by the characteristics of the organic light emitting material.
According to an aspect of the present application, there is provided a pixel arrangement structure including a plurality of pixel units arranged repeatedly, the pixel units being arranged in rows along a first direction and in columns along a second direction intersecting the first direction; the pixel units in two adjacent rows are arranged in a staggered manner in a first direction, and the pixel units in two adjacent columns are arranged in a staggered manner in a second direction; the pixel unit comprises a first sub-pixel, a second sub-pixel and a third sub-pixel, and the central connecting line of the first sub-pixel, the second sub-pixel and the third sub-pixel forms a virtual triangle; a line passing through the center of the third sub-pixel and parallel to the first direction intersects with the virtual edge of the virtual triangle along the second direction; the area of the third sub-pixel is larger than the area of the first sub-pixel and the area of the second sub-pixel.
The pixel arrangement structure is provided with a plurality of pixel units which are arranged repeatedly, the pixel units are arranged in a row along a first direction and are arranged in a column along a second direction which is intersected with the first direction, the pixel units in two adjacent rows are arranged in a staggered manner in the first direction, and the pixel units in two adjacent columns are arranged in a staggered manner in the second direction; the pixel unit comprises a first sub-pixel, a second sub-pixel and a third sub-pixel, and the central connecting line of the first sub-pixel, the second sub-pixel and the third sub-pixel forms a virtual triangle; the center connecting line of the first sub-pixel and the second sub-pixel forms a virtual edge of the virtual triangle along the second direction, and a straight line passing through the center of the third sub-pixel and parallel to the first direction intersects with the virtual edge of the virtual triangle along the second direction, so that the first sub-pixel, the second sub-pixel and the third sub-pixel are arranged tightly, and the pixel density is improved; and the area of the third sub-pixel is larger than the area of the first sub-pixel and the area of the second sub-pixel, so that when light with the same intensity is emitted, the third sub-pixel can relatively reduce the luminous power, the short service life of the third sub-pixel caused by the luminous characteristic of part of organic luminous materials is avoided, and the problem that the display effect of the OLED display device is influenced by the characteristic of the organic luminous materials is solved.
In one embodiment, in each pixel unit, a straight line passing through the center of the first sub-pixel and parallel to the first direction passes through the adjacent third sub-pixel; and/or in each pixel unit, a straight line passing through the center of the second sub-pixel and parallel to the first direction passes through the adjacent third sub-pixel.
It can be understood that, in a row of pixel units, if the first sub-pixels are arranged consecutively, the color displayed by the first sub-pixels will be more prominent. Similarly, if the second sub-pixels are arranged continuously, the color displayed by the second sub-pixels will be more prominent. In the pixel arrangement structure provided in the embodiment of the present application, in each row of pixel units, a straight line passing through the center of the first sub-pixel and parallel to the first direction passes through the adjacent third sub-pixel, so that in one row of pixel units, the adjacent two first sub-pixels are spaced apart by the third sub-pixel, thereby avoiding a color fringing of a color displayed by the first sub-pixel. Similarly, in each row of pixel units, a straight line passing through the centers of the second sub-pixels and parallel to the first direction passes through the adjacent third sub-pixels, so that in one row of pixel units, the two adjacent second sub-pixels are spaced by the third sub-pixels, and color fringes of the color displayed by the second sub-pixels are avoided.
In one embodiment, a projection of any vertex of the virtual triangle on a virtual edge opposite to the vertex and a center of a sub-pixel located on the virtual edge are not coincident with each other.
When the projection of a certain vertex of the virtual triangle on the virtual edge opposite to the vertex is superposed with the center of the sub-pixel on the virtual edge, the virtual triangle forms a right triangle, the interval between two sub-pixels on the right-angle edge of the right triangle is small, and the interval between two sub-pixels on the hypotenuse of the right triangle is large, namely, the intervals between the three sub-pixels on the three vertices of the virtual triangle are not uniform, so that the sawtooth is serious when a certain sub-pixel is displayed independently. The pixel arrangement structure provided by the embodiment of the application sets the projection of any vertex of the virtual triangle on the virtual edge opposite to the vertex and the center of the sub-pixel positioned on the virtual edge not to be overlapped, so that the three sub-pixels on the three vertexes of the virtual triangle are uniformly spaced, and the sawtooth phenomenon is weakened.
In an embodiment, a straight line passing through the center of the third sub-pixel and parallel to the first direction perpendicularly bisects a virtual edge of the virtual triangle along the second direction, that is, an interval between the first sub-pixel and the third sub-pixel is equal to an interval between the second sub-pixel and the third sub-pixel, so that the first sub-pixel, the second sub-pixel and the third sub-pixel are spaced more uniformly as far as possible while ensuring that the area of the third sub-pixel is larger than the area of the first sub-pixel and the area of the second sub-pixel.
In an embodiment, an arrangement structure of one of the two pixel units arbitrarily adjacent to each other in the second direction, which is turned by 180 degrees around an axis parallel to the second direction, is the same as an arrangement structure of the other pixel unit.
When the arrangement structure of one pixel unit in any two adjacent pixel units in the second direction after being turned for 180 degrees around the axis parallel to the second direction is the same as the arrangement structure of the other pixel unit, the arrangement structures of the two pixel units are centrosymmetric with each other before being turned, so that one row of pixel units can be displayed as two rows of pixel units through the color-borrowing principle in the second direction, the pixel density is improved, and the display precision is higher when a single row of pixel units are displayed.
In one embodiment, in any two pixel units adjacent to each other in the second direction, the first sub-pixel and the second sub-pixel in one pixel unit and the third sub-pixel in the other pixel unit are arranged in a column along the second direction; wherein the second direction is perpendicular to the first direction.
It can be understood that, when the arrangement structures of two adjacent pixel units in the second direction are symmetric to each other, one column of pixel units in the second direction can be displayed as two columns of pixel units by the color-borrowing principle. The pixel arrangement structure provided by the embodiment of the application is further arranged in two pixel units which are arbitrarily adjacent in the second direction, wherein the first sub-pixel and the second sub-pixel in one pixel unit and the third sub-pixel in the other pixel unit are arranged in a column along the second direction, so that when the first sub-pixel and the second sub-pixel of one pixel unit and the third sub-pixel of the other pixel unit form a new pixel unit in the two pixel units which are adjacent in the second direction by the color borrowing principle, the saw tooth of the new pixel unit in the second direction is minimized, and the display effect is improved.
In an embodiment, in the pixel unit of the M-th column, the third sub-pixels of the pixel units respectively located in the nth row, the N +1 th row and the N +2 th row, and in the pixel unit of the M +1 th column, a central connecting line of the third sub-pixels of the pixel units located in the N +1 th row forms a first virtual quadrangle; in the pixel units of the M column, the first sub-pixel and the second sub-pixel of the pixel unit positioned in the (N + 1) th row are positioned in the first virtual quadrangle; wherein M, N is a positive integer.
Because the central connecting line of the third sub-pixels of the four pixel units forms a first virtual quadrangle, the first sub-pixel and the second sub-pixel of one pixel unit are positioned in the first virtual quadrangle, the six sub-pixels can be combined to form four new pixel units with different arrangement modes along the diagonal direction of the first virtual quadrangle by the color borrowing principle, and the pixel density is improved. Further, when viewed from the plurality of first virtual quadrangles which are repeatedly arranged, even number of adjacent first virtual quadrangles can be combined to form a new virtual quadrangle, and more new pixel units with different arrangement modes can be obtained along the diagonal direction of the new virtual quadrangle.
In an embodiment, a central line of the first sub-pixels in a row of pixel units arranged along the first direction is parallel to the first direction, a central line of the second sub-pixels in a row of pixel units arranged along the first direction is parallel to the first direction, and a central line of the third sub-pixels in a row of pixel units arranged along the first direction is parallel to the first direction.
In a row of pixel units arranged along the first direction, the central connecting line of the first sub-pixel, the central connecting line of the second sub-pixel and the central connecting line of the third sub-pixel are all parallel to the first direction, so that any row of pixel units can be independently displayed, and when a single row of pixel units are displayed, the edge sawteeth are small, and the display precision is high.
In one embodiment, the first sub-pixel and the second sub-pixel are triangular in shape, and the third sub-pixel is circular or polygonal in shape;
optionally, the third sub-pixel is circular in shape, at least one pixel side of the first sub-pixel is configured to be concave towards its center, and at least one pixel side of the second sub-pixel is configured to be concave towards its center;
optionally, the pixel edge of the first sub-pixel, which is concave towards the center thereof, is arc-shaped, and the curvature of each pixel edge of the first sub-pixel, which is arc-shaped, is equal to the curvature of the third sub-pixel; and/or
The pixel edge which is concave inwards towards the center of the second sub-pixel is arc-shaped, and the curvature of each arc-shaped pixel edge in the second sub-pixel is equal to that of the third sub-pixel.
When the third sub-pixels are circular or regular hexagonal and the first sub-pixels and the second sub-pixels are triangular, six regular triangular sub-pixels may be uniformly arranged around one third sub-pixel, three of the six regular triangular sub-pixels are the first sub-pixels and three of the six regular triangular sub-pixels are the second sub-pixels, and the first sub-pixels and the second sub-pixels are alternately arranged around the third sub-pixels. Thus, three different sub-pixels can be arranged closely and uniformly. In the central connection direction of any two opposite triangular sub-pixels, the first sub-pixel, the third sub-pixel and the second sub-pixel are sequentially arranged, so that a pixel unit can be formed, and high-precision display is realized. In the vertical line direction of the central connecting line of any two adjacent triangular sub-pixels, the first sub-pixel and the second sub-pixel are arranged axially symmetrically by taking the vertical line of the central connecting line as a symmetry axis, and the third sub-pixel is arranged beside the first sub-pixel and the second sub-pixel along the vertical line direction of the central connecting line, so that a pixel unit can be formed by combining the first sub-pixel and the second sub-pixel, and the delicate display of a single row of pixels is realized.
In an embodiment, the first sub-pixel and the second sub-pixel are respectively red and green, and the third sub-pixel is blue. Because the service life of the blue organic luminescent material is shorter than that of the red organic luminescent material and the green organic luminescent material, the area of the blue organic luminescent material is set to be larger than that of the red organic luminescent material and that of the green organic luminescent material, so that the luminescent power of the blue sub-pixel can be relatively reduced, the loss of the blue organic luminescent material is reduced, the luminescent brightness of the sub-pixels with different colors is balanced, and the color cast is reduced.
According to another aspect of the present application, there is provided a display panel including the pixel arrangement structure according to the above embodiment.
According to still another aspect of the present application, there is provided a display device including the display panel according to the above embodiment.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of embodiments in many different forms than those described herein and that modifications may be made by one skilled in the art without departing from the spirit and scope of the application and it is therefore not intended to be limited to the specific embodiments disclosed below.
In the description of the present application, it is to be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the present application and for simplicity in description, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be considered limiting of the present application.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.
In this application, unless expressly stated or limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can include, for example, fixed connections, removable connections, or integral parts; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
In this application, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through intervening media. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.
It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Any color in nature can be formed by mixing red, green and blue colors according to different proportions, the saturation of the mixed color is determined by the proportion of the three colors, and the brightness of the mixed color is the sum of the brightness of the three colors. Each cone cell of the human eye contains a photosensitive pigment (red-sensitive pigment, green-sensitive pigment, blue-sensitive pigment) so that they can perceive the corresponding color, and thus, by harmonizing the three colors of red, green, and blue, the human eye can perceive any color change.
The sub-pixels in the display panel are made up of small cells displaying the image, which cells have a well-defined position, i.e. determined by the pixel layout, and assigned color values, i.e. determined by the pixel circuits. When different colors are required to be displayed, the three sub-pixels respectively emit light with different brightness, and the small grids are very small in size and can be visually mixed into the required color, so that the color and the position of the small grids determine the appearance of the displayed image, namely the appearance which can be perceived by human eyes.
One dimension for evaluating the display quality is the display resolution, which refers to the precision of the displayed image, specifically, how many sub-pixels can be displayed by the display panel. For example, the common resolution HD: 720 x 1280, FHD: 1080 × 1920, QHD: 1440 × 2560, UHD (2K \ 4K): 2160*3840. Taking FHD as an example, 1080R sub-pixels, 1080G sub-pixels, and 1080B sub-pixels are respectively arranged in one direction, and 1920R sub-pixels, 1920G sub-pixels, and 1920B sub-pixels are respectively arranged in the other direction.
Another dimension for evaluating display quality is ppi (pixels Per inc), also known as pixel density, which represents the number of pixels owned by an inch. For example, the resolution of FHD, 5 feet in size, has 441 PPI. Therefore, the higher the resolution, the higher the PPI may be, provided that the size of the display panel is fixed.
The other dimension for evaluating the display quality is the aperture ratio, and usually, when people look at the display panel, no unlighted part of the display panel is found, and when people look at the display panel with a magnifying glass, a lot of black unlighted parts are found, and the black unlighted parts are covered by the bright parts. That is, the light emitted by the sub-pixel is uniformly distributed to the non-luminous area, and the luminance of the sub-pixel is distributed to the non-luminous area, so that the screen is not bright enough, and the corresponding uniform luminance is not high as compared with the luminance of the sub-pixel. Therefore, it is desirable to increase the aperture ratio of the display panel, i.e. to decrease the area of the black non-light emitting region and increase the area of the light emitting region, so as to have better display quality. Meanwhile, the aperture opening ratio is improved, and the service life of the sub-pixels is prolonged.
Different pixel density and different aperture opening ratio can be obtained to different pixel arrangement modes, thereby influencing the display effect. In the OLED display device, the loss of organic light emitting materials emitting light of different colors in the light emitting process is different, and when the loss of some organic light emitting materials is more serious than that of other materials, the display effect is also affected. However, the current pixel arrangement structure still has the problem that the display effect of the OLED display device is affected due to the characteristics of the organic light emitting material.
In order to solve the above problem, an embodiment of the present application provides a pixel arrangement structure, including a plurality of pixel units arranged repeatedly, where the pixel units are arranged in rows and columns along a first direction and a second direction which are intersected with each other, and the pixel units in two adjacent rows are arranged in a staggered manner in the first direction, and the pixel units in two adjacent columns are arranged in a staggered manner in the second direction; the pixel unit comprises a first sub-pixel, a second sub-pixel and a third sub-pixel, the central lines of the first sub-pixel and the second sub-pixel are connected to form a virtual edge of the virtual triangle along the second direction, and a straight line passing through the center of the third sub-pixel and parallel to the first direction intersects with the virtual edge of the virtual triangle along the second direction, so that the first sub-pixel, the second sub-pixel and the third sub-pixel are arranged tightly, and the pixel density is improved. Based on this, the area of the third sub-pixel is further set to be larger than the area of the first sub-pixel and the area of the second sub-pixel. Therefore, when the light with the same intensity is emitted, the light emitting power of the third sub-pixel can be relatively reduced, and the short service life of the third sub-pixel caused by the light emitting characteristics of part of organic light emitting materials is avoided.
Fig. 1 shows a schematic diagram of a pixel arrangement in an embodiment of the present application, and fig. 2 shows a schematic diagram of one pixel unit of the pixel arrangement in fig. 1.
Referring to fig. 1 and 2, a pixel arrangement structure provided in an embodiment of the present application includes a plurality of pixel units 10 arranged repeatedly, the pixel units 10 are arranged in a row along a first direction X, and are arranged in a column along a second direction Y intersecting the first direction X, the pixel units 10 in two adjacent rows are arranged in a staggered manner in the first direction X, and the pixel units 10 in two adjacent columns are arranged in a staggered manner in the second direction Y; the pixel unit 10 includes a first sub-pixel 110, a second sub-pixel 120 and a third sub-pixel 130, wherein a virtual triangle T is formed by connecting the centers of the first sub-pixel 110, the second sub-pixel 120 and the third sub-pixel 130; a virtual edge of the virtual triangle T along the second direction Y is formed by connecting the centers of the first subpixel 110 and the second subpixel 120, and a straight line passing through the center of the third subpixel 130 and parallel to the first direction X intersects with the virtual edge of the virtual triangle T along the second direction Y; the area of the third subpixel 130 is larger than the area of the first subpixel 110 and the area of the second subpixel 120.
In the pixel arrangement structure provided in the embodiment of the present application, by arranging a plurality of pixel units 10 to be repeatedly arranged, the pixel units 10 are arranged in a row along a first direction X, and are arranged in a column along a second direction Y intersecting the first direction X, the pixel units 10 in two adjacent rows are arranged in a staggered manner in the first direction X, and the pixel units 10 in two adjacent columns are arranged in a staggered manner in the second direction Y; the pixel unit 10 includes a first sub-pixel 110, a second sub-pixel 120 and a third sub-pixel 130, and a virtual triangle T is formed by connecting the centers of the first sub-pixel 110, the second sub-pixel 120 and the third sub-pixel 130; a virtual edge of the virtual triangle T along the second direction Y is formed by connecting the centers of the first subpixel 110 and the second subpixel 120, and a straight line passing through the center of the third subpixel 130 and parallel to the first direction X intersects with the virtual edge of the virtual triangle T along the second direction Y, so that the first subpixel 110, the second subpixel 120 and the third subpixel 130 are arranged tightly, and the pixel density is improved; moreover, the area of the third sub-pixel 130 is larger than the area of the first sub-pixel 110 and the area of the second sub-pixel 120, so that when light with the same intensity is emitted, the third sub-pixel 130 can relatively reduce the light emitting power, thereby avoiding the short service life of the third sub-pixel 130 caused by the light emitting characteristics of part of the organic light emitting materials, and solving the problem that the display effect of the OLED display device is affected by the characteristics of the organic light emitting materials.
In some embodiments, in each pixel unit 10, a straight line passing through the center of the first subpixel 110 and parallel to the first direction X passes through the adjacent third subpixel 130. It is understood that in a row of pixel units 10, if the first sub-pixels 110 are arranged consecutively, the color displayed by the first sub-pixels 110 is more prominent. By arranging that, in each row of pixel units 10, a straight line passing through the centers of the first sub-pixels 110 and parallel to the first direction X passes through the adjacent third sub-pixels 130, two adjacent first sub-pixels 110 are spaced apart by the third sub-pixels 130 in one row of pixel units 10, thereby avoiding occurrence of color fringing of the color displayed by the first sub-pixels 110.
In some embodiments, in each pixel unit 10, a straight line passing through the center of the second sub-pixel 120 and parallel to the first direction X passes through the adjacent third sub-pixel 130, so that in one row of pixel units 10, the adjacent two second sub-pixels 120 are spaced apart by the third sub-pixel 130, thereby avoiding the occurrence of a color fringe of the color displayed by the second sub-pixels 120.
Specifically, in each pixel unit 10, one or both of a straight line passing through the center of the first sub-pixel 110 and parallel to the first direction X and a straight line passing through the center of the second sub-pixel 120 and parallel to the first direction X may pass through the adjacent third sub-pixel 130.
In some embodiments, the projection of any vertex of the virtual triangle T on the virtual edge opposite to the vertex and the center of the sub-pixel on the virtual edge are not coincident with each other. When the projection of a certain vertex of the virtual triangle T on the virtual side opposite to the vertex coincides with the center of the sub-pixel on the virtual side, the virtual triangle T forms a right triangle, the interval between two sub-pixels on the right-angle side of the right triangle is small, and the interval between two sub-pixels on the hypotenuse of the right triangle is large, that is, the intervals between three sub-pixels on the three vertices of the virtual triangle T are not uniform, so that the jagging is serious when a certain sub-pixel is displayed alone. The pixel arrangement structure provided by the embodiment of the application sets the projection of any vertex of the virtual triangle T on the virtual edge opposite to the vertex and the center of the sub-pixel positioned on the virtual edge not to be overlapped, so that the three sub-pixels on the three vertexes of the virtual triangle T are uniformly spaced, and the sawtooth phenomenon is weakened.
Further, a straight line passing through the center of the third sub-pixel 130 and parallel to the first direction X is perpendicular to and bisects a virtual edge of the virtual triangle T along the second direction Y, so that an interval between the first sub-pixel 110 and the third sub-pixel 130 is equal to an interval between the second sub-pixel 120 and the third sub-pixel 130, and thus, while ensuring that the area of the third sub-pixel 130 is larger than the area of the first sub-pixel 110 and the area of the second sub-pixel 120, the intervals among the first sub-pixel 110, the second sub-pixel 120 and the third sub-pixel 130 are more uniform as much as possible.
In some embodiments, the arrangement structure of one pixel unit 10 of any two adjacent pixel units 10 in the second direction Y after being turned over by 180 degrees along the second direction Y is the same as the arrangement structure of another pixel unit 10, so that two adjacent pixel units 10 in the second direction Y are symmetric with each other, and thus in the second direction Y, one column of pixel units 10 can be displayed as two columns of pixel units 10 by color theory, thereby increasing the pixel density and making the display precision of a single row of pixel units 10 higher.
Further, in any two pixel units 10 adjacent in the second direction Y, the first sub-pixel 110 and the second sub-pixel 120 in one pixel unit 10, and the third sub-pixel 130 in another pixel unit 10 are arranged in one column along the second direction Y; the second direction Y is perpendicular to the first direction X. Based on that any two adjacent pixel units 10 in the second direction Y are centrosymmetric to each other, the first sub-pixel 110 and the second sub-pixel 120 in one pixel unit 10 and the third sub-pixel 130 in another pixel unit 10 are further arranged in a column along the second direction Y in any two adjacent pixel units 10 in the second direction Y, so that when the first sub-pixel 110 and the second sub-pixel 120 of one pixel unit 10 and the third sub-pixel 130 of another pixel unit 10 form a new pixel unit 10 in the second direction Y in two adjacent pixel units 10 in the second direction Y through a color borrowing principle, the saw tooth of the new pixel unit 10 in the second direction Y is minimized, and the display effect is improved.
FIG. 3 is a schematic diagram of a partial sub-pixel arrangement of a pixel arrangement according to an embodiment of the present disclosure;
referring to fig. 1 and 3, in some embodiments, in the M-th row of pixel units 10, the third sub-pixels 130 of the pixel units 10 respectively located in the nth row, the (N + 1) th row and the (N + 2) th row and in the M + 1-th row of pixel units 10, the central connecting line of the third sub-pixels 130 of the pixel units 10 located in the (N + 1) th row form a first virtual quadrangle Q; and in the pixel unit 10 of the mth column, the first sub-pixel 110 and the second sub-pixel 120 of the pixel unit 10 located in the (N + 1) th row are located within the first virtual quadrangle Q; m, N is a positive integer, so that the six sub-pixels can be combined to form a plurality of new pixel units 10 with different arrangement modes along the diagonal direction of the first virtual quadrangle Q by the color borrowing principle, thereby increasing the pixel density.
Further, when viewed from the plurality of first virtual quadrangles Q arranged repeatedly, even number of adjacent first virtual quadrangles Q can be combined to form a new virtual quadrangle, and more new pixel units 10 with different arrangement modes can be obtained along the diagonal direction of the new virtual quadrangle.
In some embodiments, the central connecting line of the first sub-pixels 110 in one row of the pixel units 10 arranged along the first direction X, the central connecting line of the second sub-pixels 120 in one row of the pixel units 10 arranged along the first direction X, and the central connecting line of the third sub-pixels 130 in one row of the pixel units 10 arranged along the first direction X are all parallel to the first direction X, so that any row of the pixel units 10 can be independently displayed, and when a single row of the pixel units 10 is displayed, the edge jaggy is small, and the display fineness is high.
Fig. 4 shows a schematic diagram of a pixel arrangement in another embodiment of the present application.
Referring to fig. 4, in some embodiments, the shapes of the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 may be circular or polygonal, and particularly, may be a regular polygon and an irregular polygon. The regular polygon can be regular triangle, square, regular pentagon, regular hexagon and regular dodecagon. Taking the third sub-pixel 130 as a circle, and the first sub-pixel 110 and the second sub-pixel 120 as triangles as an example, six triangular sub-pixels may be uniformly arranged around one third sub-pixel 130, three of the six triangular sub-pixels are the first sub-pixel 110, and three of the six triangular sub-pixels are the second sub-pixel 120, and the first sub-pixel 110 and the second sub-pixel 120 are alternately arranged around the third sub-pixel 130. Thus, three different sub-pixels can be arranged closely and uniformly. In the central connection line direction of any two opposite triangular sub-pixels, the first sub-pixel 110, the third sub-pixel 130 and the second sub-pixel 120 are sequentially arranged, so that one pixel unit 10 can be formed, and high-precision display can be realized. In the perpendicular direction of the central connecting line of any two adjacent triangular sub-pixels, the first sub-pixel 110 and the second sub-pixel 120 are arranged axially symmetrically with the perpendicular of the central connecting line as a symmetry axis, and the third sub-pixel 130 is arranged beside the first sub-pixel 110 and the second sub-pixel 120 along the perpendicular of the central connecting line, and can also be combined to form a pixel unit 10, so as to realize the delicate display of a single row of pixels.
When the third sub-pixels 130 are regular hexagons, and the first sub-pixels 110 and the second sub-pixels 120 are regular triangles, six regular triangle sub-pixels, three of which are the first sub-pixels 110 and three of which are the second sub-pixels 120, may also be uniformly arranged around one third sub-pixel 130, and the first sub-pixels 110 and the second sub-pixels 120 are alternately arranged around the third sub-pixel 130, so as to realize the delicate display of a single row of pixels.
Fig. 5 shows a schematic diagram of a pixel arrangement in a further embodiment of the present application.
Referring to fig. 5, further, when the third subpixel 130 has a circular shape, at least one pixel side of the first subpixel 110 may be configured to be concave toward the center thereof, and at least one pixel side of the second subpixel 120 may be configured to be concave toward the center thereof, so that the first subpixel 110, the second subpixel 120, and the third subpixel 130 may be closely arranged under the same process conditions, and the distance between adjacent subpixels may be reduced as much as possible.
With respect to the pixel side, it is understood that in the display panel, a pixel opening may be defined by a pixel defining layer, and the organic light emitting layer of the sub-pixel is disposed in the pixel opening to avoid cross color or interference between adjacent sub-pixels. Therefore, the pixel side of the sub-pixels is the boundary of the pixel opening of the pixel defining layer, the area of the sub-pixel opening is the opening area of the pixel opening, and is also the light emitting area of the sub-pixels, and the pitch between the sub-pixels is the pitch between the pixel sides of the sub-pixels.
In one embodiment, the third sub-pixel 130 is circular, the pixel edge of the first sub-pixel 110 that is concave toward the center thereof is arc-shaped, the curvature of each arc-shaped pixel edge of the first sub-pixel 110 is equal to the curvature of the third sub-pixel 130, the pixel edge of the second sub-pixel 120 that is concave toward the center thereof is arc-shaped, and the curvature of each arc-shaped pixel edge of the second sub-pixel 120 is equal to the curvature of the third sub-pixel 130, so that when the three first sub-pixels 110 and the three second sub-pixels 120 uniformly surround the third sub-pixel 130, the arc-shaped edges of the first sub-pixel 110 and the second sub-pixel 120 close to the third sub-pixel 130 can be uniformly spaced from the third sub-pixel 130. In this case, when the three vertex positions of the first subpixel 110 and the second subpixel 120 are determined and the lowermost interval between adjacent subpixels is determined, the area of the third subpixel 130 can be maximized.
In other embodiments, the shape of the first sub-pixel 110 and the shape of the second sub-pixel 120 may be set to be different, and the curvature of the concave edge of one of the first sub-pixel 110 and the second sub-pixel 120 towards the center thereof is selected to be equal to the curvature of the third sub-pixel 130 as required.
In some embodiments, the first sub-pixel 110 and the second sub-pixel 120 are red and green, respectively, and the third sub-pixel is blue. It will be appreciated that the different colours of light have different wavelengths, with higher wavelengths meaning that the energy of the light is higher, which tends to cause decay of the organic light-emissive material, making it easier for the sub-pixels emitting photons of high energy to decay. It is known that the blue light has a shorter wavelength than the red light and the green light, and therefore, the energy of the blue light is higher, and the organic light emitting material emitting the blue light is more prone to decay, so that the light emitted from the pixel unit 10 is more prone to red, resulting in white color shift. The area of the blue organic luminescent material is set to be larger than that of the red organic luminescent material and that of the green organic luminescent material, so that the luminescent power of the blue sub-pixel can be relatively reduced, the loss of the blue organic luminescent material is reduced, the luminescent brightness of the sub-pixels with different colors is balanced, and the color cast is reduced.
