The arrangement is such that the brightness of the second pixel 12 is gradually changed in the column direction, thereby improving the display effect.
Exemplarily, as shown in fig. 9, every 1 second pixel 12 in each column is used as one second pixel group, 1 second pixel 12 (i.e., 1 second pixel group) is disposed in the first column, 2 second pixels 12 (i.e., 2 second pixel groups) are disposed in the second column, and 1 second pixel 12 (i.e., 1 second pixel group) is disposed in the third column, wherein the opening area of the second (from top to bottom) second pixel 12 in the second column is respectively the same as the opening area of one second pixel 12 in the first column, and the opening area of the first second pixel 12 in the second column is smaller than the opening area of the second pixel 12 in the second column.

The inventors of the present application have found that, in order to ensure the display effect of the display panel, it is necessary to reasonably select the aperture areas of the third color sub-pixel 11c and the sixth color sub-pixel 12c, and if the aperture areas of the first highlight sub-pixel 11d and the second highlight sub-pixel 12d are too large, the display panel is prone to display defects, for example, taking the first pixel as an example, if the aperture area ratio of the first color sub-pixel, the second color sub-pixel, the third color sub-pixel and the first highlight sub-pixel is 1:1:1:1, the luminance of the first highlight sub-pixel is too large, the display screen is prone to have a graininess, the display lines are prone to have a dotted line feeling, and if the aperture area of the first highlight sub-pixel is too small, the luminance of the display panel is too low, which is not practical, and therefore, the aperture area of the third color sub-pixel 11c, the aperture area of the sixth color sub-pixel 12c, the aperture area of the display panel, and the aperture area of the first highlight, The opening area of the first highlight color resistor 11d and the opening area of the second highlight color resistor 12d are reasonably selected.

At this time, not only the luminance of the display panel can be made higher, but also the opening areas of the first color sub-pixel 11a, the second color sub-pixel 11b and the third color sub-pixel 11c are all the same, and the opening areas of the fourth color sub-pixel 12a, the fifth color sub-pixel 12b and the sixth color sub-pixel 12c are all the same on the whole display panel, so that the display effect of the display panel is better.
Optionally, for any two adjacent second pixel groups, the opening area SW2 of the second highlight sub-pixel in the second pixel group farther from the corresponding third edge is smaller than the opening area S6 of the sixth color sub-pixel in the second pixel group closer to the corresponding third edge. Because the size relationship of the opening areas of the fourth color sub-pixel 12a, the fifth color sub-pixel 12b, the sixth color sub-pixel 12c and the second highlight sub-pixel 12d in each second pixel group is fixed, when the above setting is adopted, the opening areas of the second pixels in two adjacent second pixel groups do not differ too much, no abrupt change of brightness is caused, and the display effect of the display panel can be improved better.

For the first pixel 11 and the second pixel 122 with the above sub-pixel arrangement mode, in the display process, not only higher brightness can be achieved, but also a row of sub-pixels can be used for displaying lines with single color, so that the character effect is sharper. For example, as shown in fig. 4, the first color sub-pixel 11a and the fourth color sub-pixel 12a are both red sub-pixels (R in fig. 4), the second color sub-pixel 11B and the fifth color sub-pixel 12B are both green sub-pixels (G in fig. 4), the third color sub-pixel 11c and the sixth color sub-pixel 12c are both blue sub-pixels (B in fig. 4), the first highlight sub-pixel 11d and the second highlight sub-pixel 12d are both white sub-pixels (W in fig. 4), a red line can be displayed by using the first column of sub-pixels on the left side in fig. 4, a green line can be displayed by using the second column of sub-pixels on the left side in fig. 4, and a blue line can be displayed by using the third column of sub-pixels on the left side in fig. 4.

Illustratively, as shown in fig. 3 and 4, in the first direction x (i.e., the row direction), the up-down positions in the second direction y (i.e., the column direction) of the third color sub-pixel 11c and the first highlight sub-pixel 11d in two adjacent first pixels 11 are different, and in the first direction x (i.e., the row direction), the up-down positions in the second direction y (i.e., the column direction) of the sixth color sub-pixel 12c and the second highlight sub-pixel 12d in two adjacent second pixels 12 are different.
