46.3: Invited Paper: 7.1 inch full color flexible Micro‐LED display based on Topgate IGZO backplane

This paper proposed a prototype of flexible 7.1 inch full color micro‐LED display. The resolution is 320RGB×270 and pixel pitch is 0.432mm. Top‐gate IGZO backplane is suitable for flexible micro‐LED display with its high stability and good TFT characteristics. We adopted elastomer stamp transfer technology to transfer red, green, and blue micro‐LEDs to substrate. The micro‐LED size is 35um×25um and the luminance of the prototype can reach beyond 500nits.
