摘要： A circuit for compensating color shift of a color sequential display method includes an image processing unit and a timing control circuit. The image processing unit includes a gray level generation unit, a pre-processing unit, and a color compensation unit. The gray level generation generates first gray levels of red, green, and blue sub-pixels. The pre-processing unit generates a pure color uniformity of a display panel and a color compensation value. The color compensation unit generates a color saturation of a pixel, a compensation difference of the pixel, and gray levels of red, green, and blue sub-pixels of a compensated pixel. The timing control circuit sequences the gray levels of the red, green, and blue sub-pixels of the compensated pixel according to the color sequential display method, and outputs the gray levels of the red, green, and blue sub-pixels of the compensated pixel to the display panel.

摘要： A color adjustment method for a color sequential liquid crystal display (LCD) having at least one white light source is provided. In the color adjustment method, firstly, an original image signal is converted into a target color point located in a chromaticity diagram in a color space. Then, a modified image signal having white data is calculated according to the original image signal. Afterwards, the modified image signal is converted into a main color point located in the chromaticity diagram by using a matrix group. Then, a plurality of subfield data are calculated according to the main color point and the target color point. The subfield data are used for enabling the main color point to fall on the target color point.
