Abstract
We propose a high-speed, fine-pitch gate driver using a-IGZO TFTs. The gate driver has a pitch of 18.6μm supporting the pixel density up to 2700 pixel-per-inch (ppi) when applied to two sides of the display. Moreover, the gate driver works within a very short stage period of 1μs, which corresponds to a refresh rate of 120Hz at 8K resolution. This study enables gate driver integration for high ppi a-IGZO displays, which can be used for mobile and AR/VR applications.
