Pixel structure having red sub-pixel, green sub-pixel, blue sub-pixel and white sub-pixel

摘要

A pixel structure includes a red sub-pixel, a green sub-pixel, a blue sub-pixel and a white sub-pixel. The red sub-pixel, the green sub-pixel and the blue sub-pixel are suitable for providing a first white light, and a chroma coordinate of the first white light is (x₁, y₁). The white sub-pixel is suitable for providing a second white light, and a chroma coordinate of the second white light is (x₂, y₂). The chroma coordinate of the first white light is different from the chroma coordinate of the second white light, that is, (x₁, y₁)≠(x₂, y₂), while x₂≧x₁ and y₂≦y₁.
