Background technique

Generally, a pixel in a display panel is composed of three sub-pixels, wherein the three sub-pixels are respectively a red (R) sub-pixel, a green (G) sub-pixel and a blue (B) sub-pixel.

Therefore, in the prior art, in order to increase the light transmittance of the display panel , to increase display brightness, a white (W) sub-pixel is added to each pixel. Moreover, adding one sub-pixel to each pixel can also achieve the effect of enriching the color of the displayed picture.
