Claim:
1. A color filter, comprising a substrate, and a color resist layer and a black matrix positioned on the substrate, and the color resist layer comprises a plurality of pixel areas aligned in array, and the plurality of pixel areas are separated by the black matrix, and the pixel area comprises a sub pixel main area and a sub pixel sub area, and two sides of the sub pixel sub area are respectively provided with a first transparent electrode and a second transparent electrode electrically coupled thereto; the sub pixel sub area is made by electrochromic material, and by adjusting voltage signals applied to the two sides of the sub pixel sub area with the first transparent electrode and the second transparent electrode, color variation of the sub pixel sub area is controlled to achieve switch of the color filter between high color saturation and high brightness display modes.
