Low Power 6.0-Inch Extended Graphics Array Reflective Liquid Crystal Display using Indium Gallium Zinc Oxide Semiconductor with Electronic Paper Function

Abstract

We focused on the ultra-low leakage current of indium gallium zinc oxide (IGZO) field-effect transistors (FETs). The power consumption of an liquid crystal display (LCD) panel can be markedly reduced by significantly lowering frame frequency, i.e., stopping unnecessary data rewrites at the time of displaying still images. We successfully fabricated a 6.0-in. extended graphics array (XGA) reflective liquid crystal display (RLCD) panel integrally including a data selection demultiplexer and a scan driver and capable of displaying still images at 1/180 fps. Thus, the panel is suitable for electronic paper displays.
