Patent number: 8451199Abstract: 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.Type: GrantFiled: June 2, 2010Date of Patent: May 28, 2013Assignee: Chunghwa Picture Tubes, Ltd.Inventors: Yi-Pai Huang, Han-Ping Shieh, Yi-Ling Chen, Fang-Cheng Lin, Chun-Ho Chen, Wen-Chih Tai, Shian-Jun Chiou
