Panel-Sized TFT-LCD Column Driver

Abstract

Panel-sized TFT-LCD column drivers have been fabricated on a glass substrate with TF CMOS and low-resistivity copper-plated interconnections. These operate with a 16.25MHz internal clock, have 6b DACs, 6b accuracy with either 3072 or 1536 outputs, and use an offset-controlled amplifier. The operation of 15 inch XGA LCDs is demonstrated using panel-sized column drivers.
