Abstract
A color film substrate, a display panel and a display panel are provided. The display panel comprises a plurality of pixels arranged in a matrix. Each of the plurality of pixels includes a first sub-pixel and a plurality of second pixels. The first sub-pixel has a white color, and the plurality of second pixels has a plurality of colors different from the white color. The first sub-pixel having the white color has a reduced effective aperture area compared with the plurality of sub-pixels having the plurality of colors different from the white color.

A display panel, comprising:
- a plurality of pixels arranged in a matrix,
- wherein:
- each pixel includes a white sub-pixel, a red sub-pixel, a green sub-pixel and a blue sub-pixel arranged in a 2×2 array, the blue sub-pixel and the white sub-pixel are adjacently disposed in a same row of the array, and the red sub-pixel and the green sub-pixel are adjacently disposed in a same row of the array,
- the white sub-pixel has an irregular polygonal shape or a circular shape, with a switched-on rate of 70%-90%, and has a reduced effective aperture area compared with each of the red sub-pixel, the green sub-pixel and the blue sub-pixel, wherein the effective aperture area of a sub-pixel is an effective region capable of transmitting light there-through,
- the plurality of pixels includes a first pixel and a second pixel adjacent to the first pixel in a row direction of the pixel matrix, wherein sub-pixels having a same color in the first and second pixels are arranged in different rows and different columns of the pixel matrix,
- the blue sub-pixel and the red sub-pixel elongate along a first direction,
- along the first direction, a dimension of the effective aperture area of the red sub-pixel is at least 1.5 times greater than a dimension of the effective aperture area of the blue sub-pixel, and
- along a second direction perpendicular to the first direction, a dimension of the effective aperture area of the blue sub-pixel is at least 1.5 times greater than a dimension of the effective aperture area of the red sub-pixel.
