Eliminating crosstalk in thin-film transistor/liquid-crystal displays

Abstract

Liquid-crystal displays addressed by thin-film transistors are subject to crosstalk associated with parasitic capacitances. An addressing technique is described that provides compensation for cross-talk, eliminating its visible effects. Each row-addressing time interval is subdivided into two intervals, one of which is used for normal data transfer into the row. During the other subinterval, all gates are inactive, and a compensation voltage is applied to each column that is complementary to the data voltage for the row being addressed. © 1989 IEEE
