1. A liquid crystal display panel, comprising:
a first transparent glass layer;
a second transparent glass layer overlapping the first transparent glass layer;
two or more pixel units disposed on a side of the first transparent glass layer opposing the second transparent glass layer, each of the pixel units including a red sub-pixel, a green sub-pixel, a blue sub-pixel, and a white sub-pixel arranged in accordance with a predetermined rule;
a black matrix disposed between the pixel units to isolate two pixel units adjacent to each other; and
a fingerprint sensor disposed on the second transparent glass layer, and covered by the black matrix;
wherein
the fingerprint sensor is divided into a region corresponding to the red sub-pixel, a region corresponding to the green sub-pixel, a region corresponding to the blue sub-pixel, and a region corresponding to the white sub-pixel;
an area of the region corresponding to the red sub-pixel is larger than an area of any one of the region corresponding to the green sub-pixel, the region corresponding to the blue sub-pixel, and the region corresponding to the white sub-pixel; and
the region corresponding to the red sub-pixel is closer to the red sub-pixel, when compared to any one of the region corresponding to the green sub-pixel, the region corresponding to the blue sub-pixel, and the region corresponding to the white sub-pixel.
