Abstract

A color filter array suitable for a display panel is provided. The color filter array includes a first pixel, a second pixel, a third pixel and a forth pixel. The first pixel is consisted of a green filter, a blue filter and a transparent filter. The second pixel is consisted of a red filter, a blue filter and a transparent filter. The third pixel is consisted of a red filter, a green filter and a transparent filter. The forth pixel is consisted of a red filter, a blue filter and a green filter. The architecture of the color filter array is able to increase the image brightness of the display panel.
