    Abstract: 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.

  • Patent number: 8405675
    Abstract: A device and a method for converting three color values to four color values are provided. In the method, a first to a third color values of a pixel are obtained. Further, a first to a third difference values between every two of the first to the third color values are respectively computed. If all of the first to the third difference values are lower than a threshold, a first to a fourth color converting values are generated according to the first to the third color values, and the fourth color converting value is higher than zero. On the contrary, the fourth color converting value is zero, and the first to the third color converting values are equal to the first to the third color values, respectively. Thereby, a color break-up can be suppressed, and color saturation can be maintained.
