Genetic algorithm optimization in TFT-LCD drive system

This paper describes a novel TFT-LCD drive method for high gray scale display based on Genetic Algorithm optimization. The method can optimize scanning drive topology structure and improve the efficiency of scanning. This method uses the traditional DAC to drive the low-bit gray scale while the high-bit gray scale is generated by applying the new topology structure. This method is applied to a 1280*1024 dots RGB TFT-LCD panel which can display 256-level gray scale with 6-bit DAC source driver.
