Abstract
The present invention disclosures a color filter used for a WOLED display apparatus. The color filter includes a red pixel section, a green pixel section, a blue pixel section and a white pixel section. A red photoresist is disposed in the red pixel section, a green photoresist is disposed in the green pixel section, and a blue photoresist is disposed in the blue pixel section. The white pixel section includes a first sub-section, and a red photoresist, a green photoresist or a blue photoresist is disposed in the first sub-section. The present invention further disclosures a WOLED display apparatus including above color filter. The color filter of the present invention can reduce a Y value of chromaticity coordinate of the white pixel. Required brightness of the monochromatic pixels drops at a white image and power consumption is reduced. Accordingly, the life of display devices rises.
