The Space Modulated FRC (Frame Rate Control) method is widely used to realize a multicolor TFT-LCD This method produces intermediate gray shades by switching the efective voltage applied to the LCD from frame to frame. The conventional FRC, however, had the problem of flickering which depends on the specific image pattern Therefore, we have developed a new Adaptive Space Modulated FRC method of automatically generating the optimal timing for voltage switching from the display data As a result, we have realized a flicker-free, 16-gray shades, 4096-color display using the new FRC and an eight-level driver.
