Color gamma crosstalk (CCT) formula, which compares the luminance of three primary-color images with the luminance of gray-level image, is a way of measuring color expression. In this paper, the negative correlation between charging rate and CCT in the thin film transistor liquid crystal display (TFT-LCD) with flip pixel driven architecture is studied. Based on the analysis and understanding, line overdrive (OD) technology is applied to reduce the value of CCT to the standard range.
