The first sub-pixels 111 in the first sub-pixel array are arranged at equal intervals along the second direction Y, and the pitch of the first sub-pixels 111 along the second direction Y is shown in FIG. 5 with the second interval Y11. The second sub-pixels 112 in the multiple repeating units 11 constitute a second sub-pixel array, and the second sub-pixels 112 in the second sub-pixel array are arranged at equal intervals along the first direction X, which is shown at the third interval X12 in FIG. 6 The pitch of each second sub-pixel 112 along the first direction X is shown. The second sub-pixels 112 in the second sub-pixel array are arranged at equal intervals in the second direction Y, and the pitch of the second sub-pixels 112 in the second direction Y is shown in FIG. 6 at a fourth interval Y12. The third sub-pixels 113 in the plurality of repeating units 11 constitute a third sub-pixel array, and each third sub-pixel 113 in the third sub-pixel array is arranged at equal intervals along the first direction X, which is shown at the fifth interval X13 in FIG. 7 The pitch of each third sub-pixel 113 along the first direction X is shown. The third sub-pixels 113 in the third sub-pixel array are arranged at equal intervals along the second direction Y, and the pitch of the third sub-pixels 113 along the second direction Y is shown in FIG. 7 with a sixth interval Y13. With this arrangement, the pixel units can be arranged at equal intervals in the row direction and the column direction, which is beneficial to realize that the display panel and the display device have a better image display effect.

6 also shows four additional directions by taking the arrangement of the second sub-pixels 112 as an example, where the second sub-pixels 112 are arranged at equal intervals along the first additional direction XX; along the second additional direction XXX, the second The sub-pixels 112 are arranged at equal intervals; in the third additional direction YY, the second sub-pixels 112 are arranged at equal intervals; in the fourth additional direction YYY, the second sub-pixels 112 are arranged at equal intervals. Exemplarily, the first additional direction XX may be the direction in which the first direction X rotates counterclockwise by 75°, the second additional direction XXX may be the direction in which the first direction X rotates counterclockwise by 45°, and the third additional direction YY may be the first The direction in which the second direction Y rotates 15° counterclockwise, and the fourth additional direction YYY may be the direction in which the second direction Y rotates 45° counterclockwise.

In an embodiment, 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.

In this way, when displaying the screen with the pixel structure 10, the normal display of the white screen or the color screen can be achieved. In order to achieve the display of the picture that meets the color requirements, the colors of the sub-pixels (including the first sub-image 111, the second sub-pixel 112, and the third sub-pixel 113) may also be other colors known to those skilled in the art. There is no restriction on this.

In an embodiment, in the same repeating unit 11, the area of a 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 The area of the two sub-pixels 112.

Combining the colors of the sub-pixels shown above, that is, in the same repeating unit 11, the areas of the sub-pixels are sorted from large to small: blue sub-pixels, green sub-pixels, and red sub-pixels.

In this way, on the one hand, by setting a larger area of the blue sub-pixel, the required brightness of the blue sub-pixel can be achieved under a smaller driving current, thereby slowing down the performance degradation of the blue sub-pixel and extending its life, Furthermore, when the pixel structure 10 is applied to a display panel and a display device, the service life of the display panel and the display device can be increased. On the other hand, under the same driving conditions, the brightness of the green sub-pixel is high.

In an embodiment, referring to FIG. 8, the size X1 of the first sub-pixel 111 in the first direction X is smaller than the size X2 of the second sub-pixel 112 in the first direction X; or, the first sub-pixel 111 is in the first The size X1 in the direction X is smaller than the size X3 of the third sub-pixel 113 in the first direction X; or, the size X1 of the first sub-pixel 111 in the first direction X is smaller than the second sub-pixel 112 in the first direction X At the same time, the size X1 of the first sub-pixel 111 in the first direction X is smaller than the size X3 of the third sub-pixel 113 in the first direction X.

This arrangement is advantageous for satisfying the relative size relationship between the areas of the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113. Meanwhile, since in the same repeating unit 11, the unit group 11G and the first sub-pixel 111 are arranged side by side in the second direction Y, by setting the size of the first sub-pixel 111 in the first direction X to be smaller, in the second direction Y The size of the above is large, and the space where the repeating unit 11 is located can be fully utilized.

In one embodiment, the size X2 of the second sub-pixel 112 in the first direction is equal to the size X3 of the third sub-pixel 113 in the first direction X.

In this way, 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.

In one embodiment, the unit group 11G and the first sub-pixel 111 at least partially overlap in the first direction X projection.

Exemplarily, taking the orientation shown in FIG. 8 as an example, along the first direction X, the unit group 11G and the first sub-pixel 111 can be vertically projected on a straight line parallel to the second direction Y, the unit group 11G At least partially overlaps with the projection of the first sub-pixel 111 on this straight line.

Exemplarily, on the basis of FIG. 8, the position of the first sub-pixel 111 may also be set to translate upward in the second direction Y to ensure that the lower boundary of the first sub-pixel 111 does not exceed the upper boundary of the cell group 11G; Alternatively, the position of the first sub-pixel 111 may also be set to translate downward in the second direction Y, so as to ensure that the upper boundary of the first sub-pixel 111 does not exceed the lower boundary of the cell group 11G.

The unit group 11G and the first sub-pixel 111 can also completely overlap in the first direction X, so that the actual area occupancy rate of the sub-pixel in the space where the sub-pixel is located is higher. When the pixel structure is used for screen display, the screen display effect is better it is good.

In an embodiment, in the same repeating unit 11, the size Y1 of one first sub-pixel 111 in the second direction Y is smaller than the size of one second sub-pixel 112 and two third sub-pixels 113 in the second direction And Y2.

In this way, the relative size relationship between the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 can meet the normal display requirements. Of course, the “normal display requirements” herein may include display white balance requirements, display brightness requirements, display chromaticity requirements, and other display indicators known to those skilled in the art.
