NMOS and CMOS polysilicon drive circuits for liquid crystal displays

Abstract
A number of circuits that form the basic elements needed for integration of the drive circuits for active matrix LC displays have been investigated. The circuits have been fabricated using a low temperature polysilicon process and measurements have been made of the circuit performance. NMOS and CMOS circuits have been compared and while ratioed NMOS circuits have a poor performance in terms of speed and power, ratioless NMOS and CMOS circuit can both provide high-speed low-power operation.
