In the embodiment shown in fig. 6 and 7, the length of the green sub-pixel G and the fourth sub-pixel X in the column direction is equal to the length of the blue sub-pixel B and the red sub-pixel R in the column direction, and the length of the green sub-pixel G and the fourth sub-pixel X in the row direction is greater than the length of the blue sub-pixel B and the red sub-pixel R in the row direction, so that the area of the green sub-pixel G and the fourth sub-pixel X is greater than the area of the blue sub-pixel B and the red sub-pixel R. In the embodiments shown in fig. 5 to 7, under the condition that the number of the sub-pixels is the same, the area of the green sub-pixel G and the area of the fourth sub-pixel X with higher transmittance are increased to increase the ratio of the aperture of the green sub-pixel G to the aperture of the fourth sub-pixel X, so as to improve the transmittance of the display panel 100, enhance the display definition of the display panel 100 in a strong light environment without matching with a high-brightness backlight module, and effectively avoid the problems of poor heat dissipation effect and poor device stability caused by using the high-brightness backlight module.

By such design, the total area of the green sub-pixel G and the fourth sub-pixel X with higher transmittance is 2 times of the total area of the red sub-pixel R and the blue sub-pixel B, so that the aperture ratio of the green sub-pixel G and the fourth sub-pixel X is 2 times of the aperture ratio of the red sub-pixel R and the blue sub-pixel B, thereby effectively improving the transmittance of the display panel 100. Taking the display panel 100 as a conventional 45% ntsc (national Television Standards committee) as an example, in the conventional display panel 100, the aperture ratio of each sub-pixel is equal, and when the total area of the green sub-pixel G and the fourth sub-pixel X is designed to be 2 times of the total area of the red sub-pixel R and the blue sub-pixel B, compared with the conventional manner of equal aperture ratio, the transmittance can be improved by about 30%, so that the image display definition of the display panel 100 in a strong light environment is greatly improved, and the display effect of the display panel 100 in the strong light environment is favorably improved.
In addition to the fact that the total area of the green sub-pixel G and the fourth sub-pixel X with higher transmittance in the embodiment shown in fig. 2-6 is 2 times that of the red sub-pixel R and the blue sub-pixel B with lower transmittance, other multiples can be designed, for example, in the embodiment shown in fig. 7, the total area of the green sub-pixel G and the fourth sub-pixel X with higher transmittance is 1.5 times that of the red sub-pixel R and the blue sub-pixel B with lower transmittance, which can also increase the aperture ratio of the green sub-pixel G and the fourth sub-pixel X, and is also beneficial to increase the transmittance of the display panel 100, so as to meet the requirement of the display panel 100 on display definition under strong light, and increase the display effect of the display panel 100 under strong light.
