Flicker Reduction Driving Method for 8-Color Partial Mode TFT-LCDs Used In Cellular Phones

摘要

We have developed driving technology- to reduce the power consumption of TFT-LCDs which display information using 8 colors on a partial screen area in the standby mode of cellular phones. We propose that the LCD be driven at low frame frequency and that more unnecessary circuits be stopped intermittently when driving the LCD. We reduce flicker by making the optical response waveform for a frame like a simple pulse and by having the same waveform in the positive and negative frames.
