By using an oxide semiconductor, we successfully prototyped a 3.4-inch QHD LCD panel including data and scan drivers; their power consumption is reduced by variable frame frequency (from 1/60 fps to 120 fps) depending on images. Low frame frequency in displaying still images on a PC monitor can reduce eyestrain.
We fabricated a 3D panel by combining an OLED display and a liquid crystal parallax barrier including a driver using a crystalline oxide semiconductor in a backplane. The combination with a supersonic sensor for detecting the positions of the user and the panel can correct the position of the barrier.
