Abstract

A ZnO based display pixel structure that includes system-on-glass (SOG) substrates with embedded non-volatile resistive random access memory iNV-RRAM) is provided. Such pixels feature high frame rates and low power consumption. The entire SOG is based on ZnO devices. Different devices including TFT, TCO, RRAM, inverters, and shift registers are obtained through doping of different elements into selected ZnO active regions. This reduces the cost to package control circuitry onto a backplane of a display system, resulting in a low cost, light weight and uUra-thin display.
