Abstract

A matrix display device having an array of picture elements (12) which each comprises a serial charge redistribution D to A converter circuit that includes two transistors (30, 31) and two capacitors (34, 35), at least one of which comprises an electro-optic, e.g. liquid crystal, display element, and which are driven by switching signals and digital data signals from a drive circuit (21, 25) via row and column address conductors (18, 19) respectively. The two transistors of a picture element are of complementary type, e.g. n and p TFTs, connected to the same row conductor and operable in sequence by the switching signal on the row conductor (18). The drive circuit (21) is consequently simplified and the vertical scan direction can readily be reversed.
