  • Liquid crystal display system and pixel-charge delay circuit thereof
    Patent number: 8552954
    Abstract: A liquid crystal display system for improving display color mismatch utilizes a pixel-charge delay circuit to generate a new latch-data signal for a source driver of the liquid crystal display system according to an output-enable signal and a latch-data signal generated by a timing control circuit of the liquid crystal display system. Therefore, when the source driver charges a pixel on an mth gate line, a switch corresponding to a pixel on an (m?1)th gate line is already completely turned off.
