Power driving circuit of a thin film transistor liquid crystal display

摘要

A power driving circuit of a thin film transistor liquid crystal display includes Darlington circuits for generating voltages corresponding to the gate driving voltages required in the displays. Analog switching circuits control the application of voltages used to form the Von and Voff driving waveforms, which have driving voltage levels generated from the Darlington circuits. The phasing of the driving waveforms is controlled by a phasing signal which is received by the analog switching circuits. The power driving circuit of the present invention consumes less power than conventional driving circuits.
