Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be fully described by the detailed description with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are a part of the embodiments of the present invention, not all embodiments, and all other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without inventive efforts fall within the scope of the present invention.
Fig. 1 is a schematic structural diagram of a display substrate according to an embodiment of the present invention. As shown in fig. 1, the display substrate includes a plurality of triangular pixels 100, the triangular pixels 100 are arranged in a matrix, the arrangement direction of two adjacent triangular pixels 100 is different in a row direction X of the matrix, the arrangement direction of two adjacent triangular pixels 100 is different in a column direction Y of the matrix, each triangular pixel 100 includes a first sub-pixel 101, a second sub-pixel 102 and a third sub-pixel 103 which are closely arranged, and the first sub-pixel 101, the second sub-pixel 102 and the third sub-pixel 103 are arranged in a triangular shape.
It should be noted that the display substrate in this embodiment includes two kinds of triangular pixels 100, referring to fig. 1, the first kind is a regular triangular pixel 2/100, the second kind is an inverted triangular pixel 1/100, and the two kinds of pixels 100 are sequentially and cyclically arranged in the row direction X of the matrix. It is understood that the arrangement directions of the regular triangle pixels 2/100 and the inverted triangle pixels 1/100 are different, that is, the arrangement directions of two adjacent triangle pixels 100 are different in the row direction X of the matrix. It is to be noted that the arrangement direction of the pixels 100 in the present embodiment includes only the arrangement direction of the regular triangle pixels 2/100 and the arrangement direction of the inverted triangle pixels 1/100.
It should be noted that, in the present embodiment, the arrangement of the pixels 100 is only illustrated and not limited by the display substrate including four rows and five columns of the pixels 100.
According to the technical scheme provided by the embodiment, the regular triangle pixels 2/100 and the inverted triangle pixels 1/100 are sequentially and circularly arranged in the row direction X and the column direction Y of the pixel 100 matrix, so that the edge which is smoother than other pixel structures can be obtained by adjusting the number of the pixels 100 in each pixel row, and further, when the circular display screen is applied to the circular display screen, the edge sawtooth phenomenon of the circular display screen can be weakened, and the display effect of the circular display screen is improved.
Optionally, the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 may be any one of red, green, and blue, respectively, and the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 are different in color from each other. Since red, green, and blue are three primary colors of light, and red, green, and blue with different intensities can be mixed to obtain light of various colors, the first subpixel 101, the second subpixel 102, and the third subpixel 103 constituting one pixel 100 are each provided in one of red, green, and blue colors, and the colors are different, so that the pixels 100 can display various colors, thereby enriching the display colors of the display device.
As shown in fig. 1, the adjacently disposed sub-pixels may differ in color. Here, the adjacent arrangement includes adjacent arrangement in the same pixel and adjacent arrangement of sub-pixels in adjacent pixels. By the structure, the sub-pixels of the same color type can be arranged at intervals, and the sub-pixels of each color type can be more uniformly distributed on the display substrate, so that the local color abnormal phenomenon easily caused when the sub-pixels of the same color type are adjacently arranged is avoided, and the display effect of the display device is improved.
Optionally, in order to avoid the occurrence of the color fringing phenomenon, the sub-pixels of the three different color types at the same side end of each pixel row in the pixel matrix along the extending direction of the edge of the pixel matrix may be sequentially and cyclically arranged. For example, fig. 2 is a schematic structural diagram of another display substrate provided in an embodiment of the present invention. As shown in fig. 2, the display substrate includes a plurality of triangular pixels 100, the triangular pixels 100 are arranged in a matrix, the arrangement direction of two adjacent triangular pixels 100 is different in a row direction X of the matrix, the arrangement direction of two adjacent triangular pixels 100 is different in a column direction Y of the matrix, each triangular pixel 100 includes a first sub-pixel 101, a second sub-pixel 102 and a third sub-pixel 103 which are closely arranged, the first sub-pixel 101, the second sub-pixel 102 and the third sub-pixel 103 are in a triangular shape, the first sub-pixel 101 is a red sub-pixel, the second sub-pixel 102 is a green sub-pixel, and the third sub-pixel 103 is a blue sub-pixel. Referring to fig. 2, a first end portion, i.e., the leftmost end, of a first pixel row 201 is a red sub-pixel, a first end portion, i.e., the leftmost end, of a second pixel row 202 is a green sub-pixel, a first end portion, i.e., the leftmost end, is a blue sub-pixel, a first end portion, i.e., the leftmost end, of a third pixel row 203 is a red sub-pixel, and a first end portion, i.e., the first end portion, of a fourth pixel row 204 is a red sub-pixel, i.e., the sub-pixels at the first end portion of each pixel row are sequentially. Similarly, the sub-pixels at the second end of each pixel row in fig. 2 are arranged in a cycle of blue, red and green. It should be noted that, in order to ensure that the colors of the adjacent sub-pixels are different, the arrangement of the sub-pixels in the relevant pixel may be adjusted.
With continued reference to fig. 1, the plurality of triangular pixels 100 may each be in the shape of a regular triangle. It can be understood that the inclination angles of the edges of the pixel matrix obtained by arranging the triangular pixels 100 with different shapes are different, so that the designer can reasonably adjust the shape of the triangular pixels 100 according to the shape of the display screen and the edge extension condition for better achieving the purpose of reducing the display screen edge saw-tooth phenomenon, and the shape is not limited to a regular triangle, for example, the shape of the triangular pixels 100 can also be an isosceles triangle, as shown in fig. 3 and 4.
For example, as shown in fig. 1, the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 may have the same shape and size. The arrangement is beneficial to simplifying the forming process of the display substrate, the proportion of each sub-pixel in the obtained display substrate is the same, and the better and more controllable display effect is objectively realized.
Referring to fig. 1, when each pixel 100 has a shape of a regular triangle and the first, second, and third sub-pixels 101, 102, and 103 have the same shape and size, an inverted triangle pixel 1/100 may be obtained by rotating a regular triangle pixel 2/100 clockwise by 60 degrees around the vertex of the inverted triangle pixel 1/100 as a rotation center. It is to be understood that the association relationship between the inverted triangle pixel 1/100 and the regular triangle pixel 2/100 is not limited to the above rotation manner and rotation angle, and may be in other association relationships while ensuring the display effect of the display device. Optionally, there may be no association between the inverted triangle pixel 1/100 and the regular triangle pixel 2/100, so as to ensure that the colors of the adjacent sub-pixels are different.
It should be noted that, the sensitivity of human eyes to different colors is different, so to improve the look and feel of a user, the size of each color type sub-pixel can be adjusted according to the sensitivity of human eyes to colors. For example, fig. 5 is a schematic structural diagram of another display substrate provided in an embodiment of the present invention. As shown in fig. 5, the first sub-pixel 101 is a red sub-pixel, the second sub-pixel 102 is a green sub-pixel, and the third sub-pixel 103 is a blue sub-pixel. The display substrate shown in fig. 5 is similar to the display substrate shown in fig. 1, except that the size 103 of the third sub-pixel in fig. 5 is different from that of the first sub-pixel 101 and the second sub-pixel 102, and is larger than that of the first sub-pixel 101 and the second sub-pixel 102. Because the sensitivity of human eyes to blue is lower than that of red and green, the uniformity of each color sub-pixel in the vision of a user can be improved by enlarging the size of the blue sub-pixel, and the watching experience of the user is favorably improved. It should be noted that the green sub-pixel with relatively high eye sensitivity can be made small, and the above effect can be achieved. The present embodiment does not specifically limit the size relationship between the color type sub-pixels, and the size of each color type sub-pixel can be appropriately adjusted on the premise that a good display effect can be achieved. Further, the sub-pixels of the same color type in different pixels 100 may have the same size and shape or may have different sizes and shapes.
Fig. 6 is a schematic partial structure diagram of a circular display substrate according to an embodiment of the present invention. As shown in fig. 6, the display substrate includes a plurality of triangular pixels 100, the triangular pixels 100 are arranged in a matrix, the arrangement direction of two adjacent triangular pixels 100 is different in the row direction X of the matrix, each triangular pixel 100 includes a first sub-pixel 101, a second sub-pixel 102 and a third sub-pixel 103 which are closely arranged, and the first sub-pixel 101, the second sub-pixel 102 and the third sub-pixel 103 are triangular. In addition, in the region other than the first pixel row 110, the arrangement direction of two adjacent triangular pixels 100 is different in the column direction Y of the matrix. With reference to fig. 6, in the row direction X of the matrix, the arrangement directions of the triangular pixels 100 at two ends of the same pixel row may be the same, for example, all of the triangular pixels are regular triangles, and optionally, all of the triangular pixels are inverted triangles.
It will be appreciated that the number and arrangement of the pixels 100 in each pixel row of the display substrate is adjusted according to the shape of the edge of the display substrate so that the gap between the edge of the pixel matrix and the edge of the panel is as minimal as possible to reduce the edge aliasing phenomenon of the panel. Therefore, in practical applications, the relative position between a certain portion of pixel rows and the adjacent pixel rows can be changed according to the condition of the edge of the display screen at the corresponding position. As shown in fig. 6, to accommodate the circular panel edge, the first pixel row 110 is offset from the adjacent pixel row such that the regular triangle pixels 2/100 in the first pixel row are in the same column as the regular triangle pixels 2/100 in the adjacent pixel row, and the inverted triangle pixels 1/100 are also in the same column as the inverted triangle pixels 1/100 in the adjacent pixel row. Compared with other forms of arrangement of the first pixel rows 110, the arrangement of the first pixel rows 110 in this embodiment makes the gap between the first pixel rows and the edge of the corresponding display screen smaller, and can further achieve the effect of reducing the jaggy of the edge of the display screen.
It should be noted that, this embodiment is only described by taking a portion of the display screen including the arc-shaped edge as an example, and does not limit the shape of the display screen. In addition, the case that the pixel matrix is adjusted according to the shape of the edge of the display screen is also described as an example in the structure of the display substrate shown in fig. 6, and the arrangement of the pixels 100 can be adjusted accordingly on the premise that the gap between the pixel matrix and the edge of the display screen can be reduced. For example, the arrangement directions of the pixels 100 at both ends of the same pixel row may be different; the end pixels 100 of each pixel row on the same side of the pixel matrix may be arranged in different directions.
Illustratively, the pixel 100 may be an organic light emitting pixel. Optionally, the pixel 100 may also be a color pixel on a color film substrate.
Fig. 7 is a schematic structural diagram of a display panel according to an embodiment of the present invention. As shown in fig. 7, the display panel includes a display substrate 10 according to any embodiment of the present invention, a plurality of scan lines 11 and a plurality of data lines 12, where the plurality of scan lines 11 and the plurality of data lines 12 intersect each other.
With reference to fig. 7, the data lines 12 include a plurality of first data lines 121 and a plurality of second data lines 122, the first data lines 121 and the second data lines 122 are disposed in different layers, any two kinds of sub-pixels among the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 are connected to the first data lines 121, and the other two kinds of sub-pixels are connected to the second data lines 122. Specifically, in the present embodiment, in two adjacent rows of pixel rows, three data lines 12 are disposed, including two first partial data lines 121 and one second partial data line 122. In each row of pixels, the first sub-pixel 101, the second sub-pixel 102 and the third sub-pixel 103 are respectively connected to different data lines 12 to receive data signals of different colors. More specifically, for any row of pixel rows, three kinds of sub-pixels may be connected to the data line 12 between the row and the pixel row adjacent to the previous row, three kinds of sub-pixels may be connected to the data line 12 between the row and the pixel row adjacent to the next row, or a part of sub-pixels may be connected to the data line 12 between the row and the pixel row adjacent to the previous row, and a part of sub-pixels may be connected to the data line 12 between the row and the pixel row adjacent to the next row. In this embodiment, for any row of pixel rows, one of the sub-pixels is connected to one of the first partial data lines 121 between adjacent pixel rows of the previous row, and the other two sub-pixels are connected to one of the first partial data lines 121 and one of the second partial data lines 122 between adjacent pixel rows of the next row. It should be noted that fig. 7 illustrates the plurality of first partial data lines 121 and the plurality of second partial data lines 122 by black straight lines and black dotted straight lines, respectively, so as to distinguish the data lines 12 located in different layers. The arrangement avoids the crossing of the data lines 12 connected with two adjacent sub-pixels belonging to the same pixel 100, and ensures that the data line signals can not be in a line crossing state. It is understood that only one of two sub-pixels within the same pixel 100, which are equidistant from the same data line 12, is connected to the data line 12.
In order to simplify the manufacturing process, the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 in each pixel 100 may be disposed on the same electrode layer. It should be noted that the scan line 11 is usually a metal trace, and in order to avoid the display effect being affected by the overlap of the scan line 11 and the sub-pixels in the laminating direction of the film layers, the sub-pixels spanned by the scan line 11 can be divided into two right-angled triangle portions, and the scan line 11 is disposed between the right-angled sides of the two right-angled triangle portions close to the scan line 11. Illustratively, FIG. 8 is an enlarged view of a portion of FIG. 7, corresponding to the structure within the dashed box of FIG. 7. As shown in fig. 8, each sub-pixel corresponds to one thin film transistor 13, the gate 131 of the thin film transistor 13 is connected to the corresponding scan line 11, the source 132 is connected to the corresponding data line 12, and the drain 133 is connected to the corresponding sub-pixel. In order to prevent the scanning line 11 from shielding part of the second sub-pixel 102, the second sub-pixel 102 is divided into two parts, and the two parts are connected by the connecting line 14 arranged in a different layer with the second sub-pixel 102, so that the scanning line 11 can be prevented from shielding the second sub-pixel 102, the overall size of the second sub-pixel 102 is ensured to be unchanged, and the display effect of the display device is not affected.
Alternatively, the display panel may be a rectangular display panel as shown in fig. 7, or may be a circular display panel. The designer can adjust the arrangement of the pixels 100 according to the shape of the display panel.
