A 15-inch diagonal Super-TFT-LCD (in-plane switching mode), with a brightness of 400 cd/m2, has been developed. The moving picture image quality is improved by alternating the light on and off periods, and synchronizing those periods with a gate selection. The brightness is realized without increasing power consumption by increasing the lamp current in the on period, while the off period contributes to lamp cooing.

We have developed new driving technique, which improved the quality of moving picture on TFT-LCDs. Dynamic Contrast Compensation (DCC) method has suppressed a drop of the effective brightness. Furthermore, TFT-LCD of impulse type was realized with Super Impulse method that a combination of the black data insertion method and blinking back light systems, and it could improve the quality of the moving picture quality.
