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

Liquid-crystal displays addressed by thin-film transistors are subject to crosstalk associated with parasitic capacitances. An addressing technique that provides compensation for crosstalk, eliminating its visible effects, is described. 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 that is complementary to the data voltage for the row being addressed is applied to each column. This technique does, however, require a factor-of-two increase in bandwidth or switching speeds.<
