An improved LCD multi-line location algorithm with redundant term

摘要

A multi-line with redundant term location-driven algorithm and scheme of implementation circuit applied to LCD driver chips is presented in this paper. The multi-line location-driven algorithm reduces the number of column driver voltage level by the method of increasing the redundant column in modulation matrix and redundant data in display data matrix. In addition, implementation circuit of the algorithm is proposed. The experimental results show that the algorithm can reduce 30% power consumption and achieve higher integrity in LCD display driver chip.
