Before the detailed description of the pixel arrangement structure and the display device provided in the embodiments of the present disclosure, the following description of the related art is necessary:
in the related art, the pixel arrangement of display products is mainly classified into two types: one is the RGB standard arrangement, Real RGB; one is a Pentile arrangement that realizes white light display by pixel substitution. Although Pentile arrangement can also realize high PPI display, the number of sub-pixels is reduced by using a form of sharing the sub-pixels by adjacent pixels, so that the problems of grid, dark spots, colored edges, jagged edges and the like are difficult to avoid; the RGB standard arrangement design has technical barriers and limitations on the shape of each sub-pixel, the arrangement and shape of the pixel, and even the sub-pixel pitch.
In order to break through such technical barriers and limitations, the embodiments of the present disclosure provide a novel pixel arrangement structure and a display device having the same, which can improve a display effect and reduce a production difficulty.
Fig. 1 to 6 are schematic views illustrating a pixel arrangement structure provided in some embodiments of the present disclosure. As shown in fig. 1 to 6, the pixel arrangement structure provided by the embodiment of the present disclosure includes: first and second pixel repeating units S1 and S2 alternately arranged in a row direction, the first and second pixel repeating units S1 and S2 each including first, second, and third sub-pixels 100, 200, and 300 displaying different colors; in the first pixel repeating unit S1, centers of the first sub-pixel 100, the second sub-pixel 200, and the third sub-pixel 300 are connected as a vertex to form a first virtual triangle a, a first side of the first virtual triangle a forms a predetermined angle with the row direction, the first side is formed by connecting centers of the first sub-pixel 100 and the second sub-pixel 200, a vertex opposite to the first side is a center of the third sub-pixel 300, the predetermined angle may be, for example, 90 ° ± 45 °, and the predetermined angle is, for example, 90 ° ± 10, where the first side of the first virtual triangle is perpendicular to the row direction;
in the second pixel repeating unit S2, centers of the first sub-pixel 100, the second sub-pixel 200, and the third sub-pixel 300 are connected as a vertex to form a second virtual triangle B, a first side of the second virtual triangle B is perpendicular to a first side of the first virtual triangle a, the first side of the first virtual triangle is formed by connecting centers of the first sub-pixel 100 and the second sub-pixel 200, and a vertex opposite to the first side is a center of the third sub-pixel 300.
In the above solution, the pixel arrangement structure includes two pixel repeating units, i.e., a first pixel repeating unit S1 and a second pixel repeating unit S2, which correspond to two different subpixel arrangement modes, respectively, a first virtual triangle a is formed by connecting centers of the first subpixel 100, the second subpixel 200, and the third subpixel 300 in the first pixel repeating unit S1, a second virtual triangle B is formed by connecting centers of the first subpixel 100, the second subpixel 200, and the third subpixel 300 in the first pixel repeating unit S1, a first edge formed by connecting centers of the first subpixel 100 and the second subpixel 200 in the first virtual triangle a forms a preset angle with a row direction, a first edge formed by connecting centers of the first subpixel 100 and the second subpixel 200 in the second virtual triangle B is perpendicular to the first edge of the first virtual triangle, and the first pixel repeating unit S1 and the second pixel repeating unit S2 are alternately arranged in the row direction.
It should be noted that, in the above solution, the first side of the first virtual triangle forms a predetermined angle with the row direction, and the predetermined angle may be, for example, 90 ° ± 45 °, and at this time, a connection line between a first position point in a first sub-pixel (the first position point includes but is not limited to a center of the first sub-pixel) and a second position point in a second sub-pixel (the second position point includes but is not limited to a center of the second sub-pixel) in the first virtual triangle is perpendicular to the row direction;
accordingly, the first side of the second virtual triangle is perpendicular to the first side of the first virtual triangle, where perpendicular is substantially perpendicular, for example, 90 ° ± 10 ° between the first side of the second virtual triangle and the first side of the first virtual triangle may be considered substantially perpendicular. At this time, a connection line between a third position point in the first sub-pixel (the third position point includes but is not limited to the center of the first sub-pixel) and a fourth position point in the second sub-pixel (the fourth position point includes but is not limited to the center of the second sub-pixel) in the second virtual triangle is parallel to the row direction. The arrangement mode of the pixel arrangement structure in the embodiment of the present disclosure is RGB standard arrangement, but the arrangement mode of the second pixel repetition unit S2 is different from that of the first pixel arrangement unit, and the arrangement modes of the first sub-pixel 100, the second sub-pixel 200, and the third sub-pixel 300 are both horizontal and vertical in the pixel row direction, so that each sub-pixel can be shared between the adjacent first pixel repetition unit S1 and the second pixel repetition unit S2.
Therefore, the embodiments of the present disclosure provide a novel pixel arrangement structure, which can overcome the display problem caused by the technical barrier limitation of the related art pixel arrangement structure.
The embodiments of the present disclosure are described in more detail below.
In some exemplary embodiments, as shown in fig. 1 to 3, the pixel pattern of the second pixel repeating unit S2 is identical to a pixel pattern obtained by rotating the pixel pattern of the first pixel repeating unit S1 by 90 ° in a clockwise or counterclockwise direction as a whole.
For example, taking the example shown in fig. 1, the pixel pattern obtained by rotating the pixel pattern in the first pixel repeating unit S1 by 90 ° counterclockwise completely coincides with the second pixel repeating unit S2; in other embodiments, as shown in FIG. 2, the pixel pattern of the first pixel repeating unit S1 rotated 90 clockwise is identical to the pixel pattern of the second pixel repeating unit S2.
That is, in the present exemplary embodiment, the pattern in which the sub-pixel arrangement structure of the first pixel repeating unit S1 is rotated by 90 ° as a whole is the same as the pixel arrangement pattern of the second pixel repeating unit S2, and the size, shape, and arrangement pitch between sub-pixels in each of the first pixel repeating unit S1 and the second pixel repeating unit S2 are the same, except for the arrangement direction and arrangement position.
In addition, in the present exemplary embodiment, the size, shape and spacing of the first sub-pixel 100, the second sub-pixel 200 and the third sub-pixel 300 are not limited.
In the present exemplary embodiment, the display colors of the first sub-pixel 100, the second sub-pixel 200, and the third sub-pixel 300 can be mixed into white light, for example, the first sub-pixel 100 is a red sub-pixel (R), the second sub-pixel 200 is a green sub-pixel (G), and the third sub-pixel 300 is a blue sub-pixel (B); alternatively, the first sub-pixel 100 is a green sub-pixel (G), the second sub-pixel 200 is a red sub-pixel (R), and the third sub-pixel 300 is a blue sub-pixel (B).
The specific shape of the first sub-pixel 100, the second sub-pixel 200, and the third sub-pixel 300 is not limited, and may be, for example, a rectangle, a triangle, a pentagon, or another shape. And the opening areas of the red sub-pixel and the green sub-pixel are smaller than the opening area of the blue sub-pixel.
In the following embodiments, the pixel arrangement structure provided by the present disclosure is exemplified by the shape of each sub-pixel being a rectangle, the first sub-pixel 100 being a red sub-pixel (R), the second sub-pixel 200 being a green sub-pixel (G), and the third sub-pixel 300 being a blue sub-pixel (B).
Further, in the present exemplary embodiment, as shown in fig. 3, the pixel arrangement structure includes a plurality of pixel columns arranged in a row direction, in each of which the first pixel repeating unit S1 and the second pixel repeating unit S2 are alternately arranged; alternatively, as shown in fig. 1 and 2, the pixel arrangement structure includes a first pixel column including a plurality of the first pixel repeating units S1 sequentially arranged in a column direction and a second pixel column including a plurality of the second pixel repeating units S2 sequentially arranged in a column direction, which are alternately arranged in the row direction.
That is, in the column direction, the arrangement of the sub-pixels in each pixel unit on the same pixel column is the same, i.e., both are the first pixel repeating unit S1 or both are the second pixel repeating unit S2; alternatively, the first pixel repeating unit S1 and the second pixel repeating unit S2 may be alternately arranged in the column direction and on the same pixel column.
In the pixel arrangement structure in the embodiment of the disclosure, the pixel pattern of the second pixel repeating unit S2 is the same as the pattern obtained by rotating the first pixel repeating unit S1 by 90 ° clockwise or counterclockwise, taking the example that the third sub-pixel 300 is a blue sub-pixel and the third sub-pixel 300 is a rectangle as shown in the figure, in the pixel row direction, the arrangement manner of the third sub-pixel 300 is horizontal or vertical, so that the first sub-pixel 100 and the second sub-pixel 200 in the first pixel repeating unit S1 can also use the third sub-pixel 300 in the second pixel repeating unit S2, and thus, the pixel arrangement structure provided in the embodiment of the disclosure has the advantages of two pixel arrangement structures, namely Real RBG arrangement and Pentile arrangement, and can effectively improve the display effect.
Fig. 4 is a schematic structural diagram of other embodiments of the present disclosure.
In other embodiments of the present disclosure, as shown in fig. 4, in the same pixel row, the first sub-pixel 100 in the first pixel repeating unit S1 and the second pixel repeating unit S2 adjacent to the first pixel repeating unit S1 are adjacent to each other, and the width of the first sub-pixel 100 in the first pixel repeating unit S1 is the same as that of the first sub-pixel 100 in the second pixel repeating unit S2 in the column direction, so that the light emitting material layers of the first sub-pixel 100 in the first pixel repeating unit S1 and the first sub-pixel 100 in the second pixel repeating unit S2 can be formed by evaporation through the same pixel opening on the mask plate.
The embodiment shown in fig. 4 is different from the embodiment shown in fig. 1in that the first sub-pixel 100 in the first pixel repeating unit S1 and the first sub-pixel 100 in the second pixel repeating unit S2 have the same width in the column direction, and are both x, for example, the arrangement direction of the second sub-pixel 200 and the third sub-pixel 300 in the first pixel repeating unit S1 is perpendicular to the arrangement direction of the second sub-pixel 200 and the third sub-pixel 300 in the second pixel repeating unit S2, and the arrangement direction of the first sub-pixel 100 in the first pixel repeating unit S1 is the same as the arrangement direction of the first sub-pixel 100 in the second pixel repeating unit S2.
In the embodiment shown in fig. 4, when the distance between two adjacent first sub-pixels 100 in the first pixel repeating unit S1 and the second pixel repeating unit S2 is small, the manufacturing difficulty and yield of a Mask blank (Mask) are affected. Therefore, in the embodiment shown in fig. 4, two adjacent first sub-pixels 100 may be designed to have the same width in the column direction, that is, two adjacent first sub-pixels 100 are flush with each other in the row direction, so that two adjacent first sub-pixels 100 may be designed to be arranged in 2in 1, that is, two adjacent first sub-pixels 100 are integrated into the same opening on the evaporation mask plate.
Because a Pixel Definition Layer (PDL) is disposed on a display substrate, for example, an OLED display substrate, and a groove (gap) is formed on the pixel definition layer to define each sub-pixel, when the light emitting material layer on the first sub-pixel 100 is evaporated, the light emitting material layers in two sub-pixels are still formed in different sub-pixel grooves, and the display function of the first sub-pixel 100 is not affected, so that the above-mentioned scheme can improve the aperture ratio of the first sub-pixel 100 under the same PDL gap, thereby bringing better image quality display effect and display performance, and simultaneously reducing the mask plate production difficulty of the first sub-pixel 100, improving the yield, and improving the aperture ratio of the first sub-pixel 100.
In some embodiments, as shown in fig. 4, in the first pixel repeating unit and the second pixel repeating unit which are adjacently arranged in the row direction, the pitch of two first sub-pixels 100 of the same color in the row direction is smaller than the pitch value between any two adjacent sub-pixels of different colors. That is, the distance between the adjacent first sub-pixels 100 is designed to be smaller than the distance between the conventional sub-pixels, which is beneficial to realizing the 2in 1 design of the first sub-pixels 100, that is, the two adjacent first sub-pixels 100 are integrated into the same opening on the vapor deposition mask plate.
In the present exemplary embodiment, the sizes of the first sub-pixel 100, the second sub-pixel 200, and the third sub-pixel 300 may be defined as follows:
the width of the first sub-pixel 100 in the first pixel repeating unit S1 in the column direction is the same as the width of the second sub-pixel 200 in the second pixel repeating unit S2 in the column direction, and is x; the width of the second sub-pixel 200 in the first pixel repeating unit S1 in the column direction is the same as the width of the third sub-pixel 300 in the second pixel repeating unit S2 in the column direction, and is y.
Taking the example shown in fig. 4 as an example, taking each sub-pixel as a rectangle, the length and width of the sub-pixel refer to the width of the sub-pixel in the row direction and the length in the column direction in the first pixel repeating unit S1, so that the width of the first sub-pixel 100 is the same as the width of the second sub-pixel 200 in each pixel repeating unit; the length of the second sub-pixel 200 is the same as the width of the third sub-pixel 300; the length of the first sub-pixel 100 and the width of the second sub-pixel 200 are not limited. In addition, the distance between the second sub-pixel 200 in the first pixel repeating unit S1 and the second sub-pixel 200 in the second pixel repeating unit S2, and the distance between the third sub-pixel 300 in the first pixel repeating unit S1 and the third sub-pixel 300 in the second pixel repeating unit S2 may be designed to be 1in 1 (i.e., one mask opening for each sub-pixel).
Further, in the present exemplary embodiment, the pixel arrangement structure includes a first pixel column including a plurality of the first pixel repeating units S1 sequentially arranged in a column direction and a second pixel column including a plurality of the second pixel repeating units S2 sequentially arranged in a column direction, which are alternately arranged in the row direction.
That is, in the row direction, the first pixel repeating unit S1 and the second pixel repeating unit S2 are alternately arranged on the same row; in the column direction, the arrangement of the sub-pixels in each pixel unit on the same pixel column is the same.
In other embodiments, the pixel arrangement structure may further include a plurality of pixel columns arranged along the row direction, and the first pixel repeating unit S1 and the second pixel repeating unit S2 in each pixel column are alternately arranged.
Fig. 5 is a schematic diagram of a pixel arrangement structure according to another embodiment of the disclosure.
As shown in fig. 5, in other exemplary embodiments, the pixel arrangement structure includes a first pixel column and a second pixel column alternately arranged along a row direction, the first pixel column includes a plurality of the first pixel repeating units S1 sequentially arranged along a column direction, and the second pixel column includes a plurality of the second pixel repeating units S2 sequentially arranged along a column direction; in the first pixel column, at least two rows of first pixel repeating units S1 arranged adjacently form a group, and the third sub-pixels 300 in the same group of pixel repeating units are adjacent and have the same width in the row direction, so that the light-emitting material layers of the third sub-pixels 300 in the same group of pixel repeating units can be formed through evaporation through the same pixel opening on the mask plate.
The embodiment shown in fig. 5 described above differs from the embodiment shown in fig. 1 only in that,
each pixel repeating unit in the same pixel column is the same, and in the first pixel column where the first pixel repeating unit S1 is located, the distance between two adjacent third sub-pixels 300 can be made small, and the widths in the row direction are the same, so that the light emitting material layers of the third sub-pixels 300 in the same group of pixel repeating units can be formed through evaporation through the same pixel opening on the mask plate. In this way, two adjacent third sub-pixels 300 can be designed to be arranged in 2in 1, that is, the two adjacent third sub-pixels 300 are integrated into the same opening on the vapor deposition mask plate.
According to the scheme, the aperture ratio of the third sub-pixel 300 can be improved under the same PDL gap, so that better image quality display effect and display performance are achieved, meanwhile, when the first pixel column where the first pixel unit is located is used for evaporating the luminescent material, due to the fact that the first pixel column and the second pixel column are arranged alternately, the evaporation mask plate can be designed into the evaporation strip (slit strip), the aperture ratio of the third sub-pixel 300 is improved, the production difficulty of the evaporation strip of the third sub-pixel 300 is reduced, and the yield is improved.
In some embodiments, as shown in fig. 5, the pitch of the third sub-pixel 300 in the same group of pixel repeating units in the column direction is smaller than the pitch value between any two adjacent sub-pixels of different colors in the first pixel repeating unit and the second pixel repeating unit adjacently arranged in the row direction.
That is, the distance between the adjacent third sub-pixels 300 is designed to be smaller than the distance between the conventional sub-pixels, which is beneficial to realizing the 2in 1 design of the third sub-pixels 300, that is, the adjacent two third sub-pixels 300 are integrated into the same opening on the vapor deposition mask plate.
Further, in the present exemplary embodiment, the pattern in which the sub-pixel arrangement structure of the first pixel repeating unit S1 is rotated by 90 ° as a whole is the same as the pixel arrangement pattern of the second pixel repeating unit S2, and the size, shape, and arrangement pitch between sub-pixels in each of the first pixel repeating unit S1 and the second pixel repeating unit S2 are the same, only the arrangement direction and the arrangement position are different.
In addition, in the present exemplary embodiment, the size, shape and spacing of the first sub-pixel 100, the second sub-pixel 200 and the third sub-pixel 300 are not limited.
In addition, in this embodiment, the third sub-pixels 300 are arranged in the same pixel column direction, but are not arranged in the same pixel column direction, that is, for example, in the illustrated embodiment, the third sub-pixels 300 are arranged vertically and horizontally on the adjacent pixel columns, and the vertically arranged third sub-pixels 300 and the horizontally arranged third sub-pixels 300 are spaced apart in the row direction.
Fig. 6 is a schematic diagram illustrating a pixel arrangement structure according to another exemplary embodiment of the present disclosure.
As shown in fig. 6, in the present exemplary embodiment, two adjacent first sub-pixels 100 in the same pixel row and two adjacent third sub-pixels 300 in the same pixel column are both designed to be arranged in 2in 1, and based on the above scheme, the aperture ratios of the first sub-pixels 100 and the third sub-pixels 300 can be simultaneously increased under the same PDL gap, and the display effect and performance of the display panel can be improved; meanwhile, the production difficulty of the vapor plating mask plates of the first sub-pixel 100 and the third sub-pixel 300 is reduced, and the yield is improved.
In addition, in the pixel arrangement structure provided in the present disclosure, as shown in the figure, the first virtual triangle a and the second virtual triangle B are both isosceles triangles, a central connecting line of the first sub-pixel 100 and the third sub-pixel 300 is a waist of the isosceles triangle, and a central connecting line of the second sub-pixel 200 and the third sub-pixel 300 is another waist of the isosceles triangle. That is, the third sub-pixel 300 is located at the middle of the central connecting line of the first sub-pixel 100 and the second sub-pixel 200.
It is understood that, in practical applications, the shape, size, pitch and specific arrangement position of the first sub-pixel 100, the second sub-pixel 200 and the third sub-pixel 300 are not limited thereto.
It should be understood that any variation based on the embodiments of the present disclosure, for example, a pixel arrangement structure including four sub-pixels in each pixel repeating unit, should also fall within the scope of the embodiments of the present disclosure based on the same inventive concept.
