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.
