When a pixel and a signal line driver circuit are made up of semi-amorphous TFTs, an amplitude for driving the pixel has to be made larger, and a high power supply voltage is needed. The high power supply voltage increases power consumption in the case of partial drive. According to the invention, in...http://www.google.de/patents/US7477216?utm_source=gb-gplus-sharePatent US7477216 - Display device and electronic apparatus
