63.1: An Ultra High Density 736-ppi Liquid Crystal Display using InGaZnO Platform

We have developed a 736ppi (WQXGA) LCD which pixel density reach 4k smart‐phone for the first time using oxide semiconductor. Utilizing the highly scalable channel etch type InGaZnO‐TFT and a novel transparent contact structure, more than 50% of the aperture ratio was achieved using patterning dimen...

Description
Summary:We have developed a 736ppi (WQXGA) LCD which pixel density reach 4k smart‐phone for the first time using oxide semiconductor. Utilizing the highly scalable channel etch type InGaZnO‐TFT and a novel transparent contact structure, more than 50% of the aperture ratio was achieved using patterning dimensions of a manufacturing backplane.
