Abstract
An oxide semiconductor thin film transistor (TFT) has much higher mobility than an amorphous silicon (a-Si) TFT, which leads to realization of larger displays with higher definition. Moreover, it has much lower off leak current than the a-Si TFT. We have focused on this feature and successfully fabricated a low-power 6.0-inch extended graphics array (XGA) transmissive liquid crystal display (LCD) with source and scan drivers integrated on a glass substrate. In order to realize low power consumption, unnecessary rewriting is not performed at the time of still image display. The interval between rewrite operations in our panel could be extended to about 1 min (= 1/60 fps) at the time of displaying still images. The power consumption of the drivers at 1/60 fps can be about 1/3,600 of that at 60 fps. We also discuss burn-in and flickers, which might be observed when this driving method is applied.
