Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a schematic diagram of a pixel structure according to an embodiment of the present invention. Referring to fig. 1, the pixel structure 10 includes: a plurality of repeating units 11 arranged in an array; the repeating unit 11 includes one first subpixel 111, one second subpixel 112, and two third subpixels 113. The second subpixel 112 and the third subpixel 113 in the same repeating unit 11 are arranged in the second direction Y to constitute a unit group 11G; the unit group 11G in the same repeating unit 11 is arranged along the first direction X with the first subpixel 111; wherein the first direction X intersects the second direction Y. In one embodiment, the first direction X is perpendicular to the second direction Y, for example, the first direction X is a row direction and the second direction Y is a column direction.
Therefore, the embodiment of the invention provides a new pixel arrangement mode.
Here, the geometric center of the cell group 11G and the geometric center of the first subpixel 111 are aligned in the first direction X, i.e., a direction connecting the two geometric centers is parallel to the first direction X. Each repeating unit 11 comprises two third sub-pixels 113, and a combination algorithm (driving method) can enable one of the third sub-pixels 113 and the first sub-pixel 111 and the second sub-pixel 112 located in the same repeating unit 11 to form a pixel unit; the other third sub-pixel 113 in the repeating unit 11 and the first sub-pixel 111 and the second sub-pixel 112 in the repeating unit 11 in the adjacent row form another pixel unit, that is, the first sub-pixel 111 and the second sub-pixel 112 in the repeating unit 11 and the one third sub-pixel 113 in the other repeating unit 11 may form a pixel unit. Thus, two pixel units may be formed corresponding to one repeating unit 11, and by sharing the first and second sub-pixels 111 and 112, a higher density of pixel units may be achieved, so that a high PPI may be achieved when the pixel structure is applied for display.
Optionally, fig. 2 is a schematic view of another pixel structure provided in the embodiment of the present invention. Referring to fig. 1 and 2, in the same repeating unit 11, along the second direction Y, the arrangement of one second sub-pixel 112 and two third sub-pixels 113 may include: a second subpixel 112, a third subpixel 113, and a third subpixel 113; or a third sub-pixel 113, a second sub-pixel 112, and a third sub-pixel 113.
So configured, the design flexibility of the second sub-pixel 112 and the third sub-pixel 113 may be improved.
Of course, as will be understood by those skilled in the art, for the pixel arrangement mode in which two third sub-pixels 113 are adjacently disposed, the arrangement sequence of the sub-pixels in the group of pixels 11G may further include: along the second direction Y, the third sub-pixel 113, and the second sub-pixel 112.
Alternatively, with continued reference to fig. 1 and 2, a plurality of repeating units 11 are arranged to form a pixel structure 10, and in the pixel structure 10, the repeating units 11 are arranged in alignment and in repetition in both the first direction X and the second direction Y.
Illustratively, the first direction X is a row direction of the array, and the second direction Y is a column direction of the array; the repeating units 11 in different columns of the same row are aligned; the repeating units 11 of different rows in the same column are aligned.
With such an arrangement, the design difficulty of the pixel structure 10 can be reduced.
It should be noted that fig. 1 and fig. 2 only exemplarily show 3 rows and 4 columns of the repeating units 11, and do not limit the pixel structure 10 provided in the embodiment of the present invention. In other embodiments, the number and the row-column arrangement of the repeating units 11 may be set according to the actual requirement of the pixel structure 10, which is not limited in the embodiment of the invention.
Optionally, fig. 3 is a schematic diagram of another pixel structure provided in the embodiment of the present invention. Referring to fig. 3, in the pixel structure 10, in the first direction X, the i-th row of the plurality of repeating units 11 is arranged to be shifted from the i + 1-th row of the plurality of repeating units 11, and the i-th row of the plurality of repeating units 11 is arranged in the same manner as the i + 2-th row of the plurality of repeating units 11, where i is an integer equal to or greater than 1.
Illustratively, the first direction X is a row direction of the array, and the second direction Y is a column direction of the array; when the value of i is an odd number, the repeating units 11 in the odd-numbered rows and the repeating units 11 in the even-numbered rows are arranged in a staggered manner, the repeating units 11 in the odd-numbered rows are arranged in an aligned manner in the column direction, and the repeating units 11 in the even-numbered rows are arranged in an aligned manner in the column direction. With such an arrangement, in the pixel structure 10, along the column direction, at least part of the columns of pixel structures may simultaneously include the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113, which is beneficial to improving the uniformity of color development.
Alternatively, the plurality of repeating units 11 of the ith row are staggered from the plurality of repeating units of the (i + 1) th row by a preset distance W1. Preferably, the preset distance W1 is one-half the width W2 of the repeat unit 11; wherein the width of the repeating unit 11 is the length of the repeating unit 11 in the first direction X.
For example, fig. 4 is a schematic diagram of another pixel structure provided in the embodiment of the present invention. Referring to fig. 4, the first direction X is a row direction and the second direction Y is a column direction. When the value of i is odd, the repeating units 11 in the odd-numbered rows are staggered from the repeating units 11 in the even-numbered rows by a preset distance W1, and the preset distance W1 is the width W2 of one-half of the repeating units 11; wherein the width of the repeating unit 11 is the length of the repeating unit 11 in the row direction. With this arrangement, each column of the pixel structure 10 can include the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 at the same time, so that when the pixel structure 10 is used to display a picture, the uniformity of color rendering of the picture is high.
Illustratively, the repeating unit 11 of the 2 nd row includes two third sub-pixels 113, in combination with an algorithm (i.e., a driving method), wherein one third sub-pixel 113 constitutes one pixel unit with the first sub-pixel 111 and the second sub-pixel 112 located in the same repeating unit 11; the second sub-pixel 112 and the first sub-pixel 111 in the repeating unit 11 and the third sub-pixel 113 and the first sub-pixel 111 in the repeating unit 11 of the previous row (row 1) constitute another pixel unit; another third sub-pixel 113 in the repeating unit 11 constitutes another pixel unit with the first sub-pixel 111 located in the same repeating unit 11 and the first sub-pixel 111 and the second sub-pixel 112 located in the next row (row 3); the second sub-pixel 112 and the first sub-pixel 111 in the repeating unit 11 of the next row (row 3) also constitute still another pixel unit with one third sub-pixel 113 included in itself (the repeating unit of row 3). Thus, by sharing the first and second sub-pixels 111 and 112, a higher density of pixel units can be achieved, thereby achieving a high PPI.
In addition, each column of sub-pixels may include a first sub-pixel 111, a second sub-pixel 112, and a third sub-pixel 113, so that when the pixel structure is applied to display, the display color of the screen is uniform. Alternatively, when the preset distance W1 is one-half of the width W2 of the repeating unit 11, the geometric centers of the first subpixels 111 arranged in the second direction Y and the geometric centers of the cell group 11G in the same repetition are aligned in the second direction Y by designing the lengths of the first subpixels 111 and the cell group 11G in the repeating unit 11 in the first direction, that is, the direction of the line connecting the geometric centers is parallel to the second direction Y. Of course, it can be understood by those skilled in the art that the second sub-pixel 112 and the third sub-pixel 113 in the same group 11G can be aligned in the second direction by designing the sizes of the second sub-pixel 112 and the third sub-pixel 113, that is, the connection line of the two geometric centers is parallel to the second direction Y.
Illustratively, with continued reference to fig. 4, the second sub-pixel 112 and the third sub-pixel 113 of the odd-numbered row repeating unit 11 are aligned with the first sub-pixel 111 of the even-numbered row repeating unit 11.
With such an arrangement, when the pixel structure 10 is used for displaying a picture, the color rendering uniformity is ensured to be high.
In the above embodiment, the width-to-length ratio of the repeating unit 11 is exemplarily shown to be 1: 2. This helps to make the arrangement of the repeating units more compact.
In addition, it should be noted that the above "aligning in the first direction X" and "aligning in the second direction Y" are not "aligning" in a mathematical sense, and it is understood that the distance between the positions thereof is within a certain preset threshold range, and of course, a person skilled in the art can understand that the preset threshold range can be set according to actual requirements of the pixel structure, and the embodiment of the present invention does not limit this. Similarly, the "the direction of the connection line between the two geometric centers is parallel to the first direction X" and the "the direction of the connection line between the two geometric centers is parallel to the second direction Y" are not mathematically parallel, and it can be understood that the included angle between the two directions is within a certain preset angle threshold range.
Optionally, with continuing reference to fig. 4, for the pixel structure 10, in the same repeating unit 11, along the second direction Y, the arrangement manner of one second sub-pixel 112 and two third sub-pixels 113 includes: a second sub-pixel 112, a third sub-pixel 113, and a third sub-pixel 113. Thus, the mask openings can be shared when the third sub-pixels 113 are deposited, thereby reducing the difficulty in designing the mask.
It should be noted that when only realizing high PPI is considered, the arrangement of the second sub-pixels 112 and the third sub-pixels 113 may also be other ways, and for example, in the same repeating unit 11, along the second direction Y, the arrangement of one second sub-pixel 112 and two third sub-pixels 113 may also be: a third sub-pixel 113, a second sub-pixel 112, and a third sub-pixel 113. In addition, on the basis of the pixel structure 10 shown in fig. 4, a sub-pixel array formed by each of the three sub-pixels can be obtained.
For example, fig. 5 is a schematic distribution diagram of a first sub-pixel in a pixel structure according to an embodiment of the present invention, fig. 6 is a schematic distribution diagram of a second sub-pixel in a pixel structure according to an embodiment of the present invention, and fig. 7 is a schematic distribution diagram of a third sub-pixel in a pixel structure according to an embodiment of the present invention. Referring to fig. 5-7, in the pixel structure 10, the first sub-pixels 111 in the plurality of repeating units 11 constitute a first sub-pixel array, each first sub-pixel 111 in the first sub-pixel array is disposed at equal intervals along a first direction X (exemplarily, shown as a first interval X11 in fig. 5), and each first sub-pixel 111 in the first sub-pixel array is disposed at equal intervals along a second direction Y (exemplarily, shown as a second interval Y11 in fig. 5); the second sub-pixels 112 in the plurality of repeating units 11 constitute a second sub-pixel array, each second sub-pixel 112 in the second sub-pixel array is disposed at equal intervals along the first direction X (exemplarily, illustrated as a third interval X12 in fig. 6), and each second sub-pixel 112 in the second sub-pixel array is disposed at equal intervals along the second direction Y (exemplarily, illustrated as a fourth interval Y12 in fig. 6); the third sub-pixels 113 in the plurality of repeating units 11 constitute a third sub-pixel array, each third sub-pixel 113 in the third sub-pixel array is disposed at equal intervals in the first direction X (exemplarily, illustrated as a fifth interval X13 in fig. 7), and each third sub-pixel 113 in the third sub-pixel array is disposed at equal intervals in the second direction Y (exemplarily, illustrated as a sixth interval Y13 in fig. 7). Due to the arrangement, the pixel units can be arranged in the row direction and the column direction at equal intervals, and a good image display effect is achieved.
In addition, it should be noted that fig. 6 also exemplarily shows four additional directions by taking the arrangement of the second sub-pixels 112 as an example, wherein the second sub-pixels 112 are arranged at equal intervals along the first additional direction XX; along the second additional direction XXX, the second sub-pixels 112 are equally spaced; along the third additional direction YY, the second sub-pixels 112 are equally spaced; the second sub-pixels 112 are arranged at equal intervals along the fourth additional direction YYY. For example, the first additional direction XX may be a direction in which the first direction X is rotated counterclockwise by 75 °, the second additional direction XXX may be a direction in which the first direction X is rotated counterclockwise by 45 °, the third additional direction YY may be a direction in which the second direction Y is rotated clockwise by 75 °, and the fourth additional direction YYY may be a direction in which the second direction Y is rotated clockwise by 45 °.
Optionally, the first sub-pixel 111 is a blue sub-pixel, the second sub-pixel 112 is a red sub-pixel, and the third sub-pixel 113 is a green sub-pixel.
With this arrangement, when a screen is displayed by using the pixel structure 10, normal display of a white screen or a color screen can be realized. It should be noted that, in order to display a picture meeting the color requirement, the color of the sub-pixels (including the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113) may also be other colors known by those skilled in the art, and the embodiment of the invention is not limited thereto.
Optionally, in the same repeating unit 11, the area of the single third sub-pixel 113 is between the area of the first sub-pixel 111 and the area of the second sub-pixel 112, and the area of the first sub-pixel 111 is larger than the area of the second sub-pixel 112.
In combination with the colors of the sub-pixels shown above, i.e. in the same repeating unit 11, the areas of the sub-pixels are ordered from large to small as: blue sub-pixel, green sub-pixel, red sub-pixel.
So set up, on the one hand, through setting up great blue sub-pixel's area, can realize blue sub-pixel's demand luminance under less drive current to slow down the decline of blue sub-pixel's performance, prolong its life-span, and then when being applied to display panel and display device with this pixel structure 10, can improve display panel and display device's life. On the other hand, under the same driving conditions, the luminance of the green sub-pixel is high, and the luminance of the display screen can be ensured by setting the area of the green sub-pixel to be between the area of the blue sub-pixel and the area of the red sub-pixel.
Optionally, fig. 8 is a schematic structural diagram of a repeating unit provided in an embodiment of the present invention. Referring to fig. 8, a size X1 of the first sub-pixel 111 in the first direction X is smaller than a size X2 of the second sub-pixel 112 in the first direction X, and/or a size X1 of the first sub-pixel 111 in the first direction X is smaller than a size X3 of the third sub-pixel 113 in the first direction X.
So configured, it is beneficial to satisfy the relative size relationship among the areas of the first sub-pixel 111, the second sub-pixel 112 and the third sub-pixel 113. Meanwhile, since the unit group 11G and the first subpixel 111 are arranged in parallel in the second direction Y in the same repeating unit 11, the space where the repeating unit 11 is located can be fully utilized by setting the first subpixel 111 to have a small size in the first direction X and a large size in the second direction Y.
Optionally, a size X2 of the second sub-pixel 112 in the first direction is equal to a size X3 of the third sub-pixel 113 in the first direction X.
With such an arrangement, the design difficulty of the second sub-pixel 112 and the third sub-pixel 113 can be simplified, thereby reducing the overall design difficulty of the pixel structure 10.
Optionally, the projection of the cell group 11G and the first subpixel 111 in the first direction X at least partially overlap.
Of course, the cell group 11G and the first sub-pixel 111 may also be completely overlapped in the first direction X, so that the actual area occupancy of the sub-pixel in the space where the sub-pixel is located is high, and when the pixel structure is used for displaying the picture, the picture displaying effect is good.
Optionally, in the same repeating unit 11, the size Y1 of one first sub-pixel 111 in the second direction Y is smaller than the sum Y2 of the sizes of one second sub-pixel 112 and two third sub-pixels 113 in the second direction.
By such an arrangement, the relative size relationship among the first sub-pixel 111, the second sub-pixel 112 and the third sub-pixel 113 is favorable for meeting the normal display requirement. Of course, the "normal display requirements" herein may include display white balance requirements, display brightness requirements, display chromaticity requirements, and other display metrics known to those skilled in the art.
It should be noted that "the sum Y2 of the sizes of the second sub-pixel 112 and the two third sub-pixels 113 in the second direction Y" may be understood as the width of the space in which the second sub-pixel 112 and the two third sub-pixels 113 are located in the second direction Y, which includes the width between the second sub-pixel 112 and the third sub-pixel 113 and the width between the two adjacent third sub-pixels 113.

The display substrate may be an active light emitting diode display substrate, such as an OLED display substrate, a quantum dot display substrate, or the like, and may also be a display substrate used in other display technologies known to those skilled in the art, which is not limited in the embodiments of the present invention.

The light-emitting layer 353 may adopt the pixel structure described above. Therefore, by adopting the pixel structure and combining with an algorithm, high PPI display of the light-emitting diode display panel can be realized when a picture is displayed.
