Driving circuit and driving method for active matrix liquid crystal display using optical sensor

摘要

A driving circuit of an active matrix liquid crystal display (LCD) ( 600 ) having an LCD panel includes a plurality of gate lines ( 601 ) that are parallel to each other; a plurality of data lines ( 602 ) that are parallel to each other and across the gate lines; a gate driving circuit ( 610 ) connected to the gate lines; a data driving circuit ( 620 ) connected to the data lines; a timing control circuit ( 630 ) configured for driving the data driving circuit and the gate driving circuit; and an optical sensor ( 690 ) connected to the timing control circuit. The optical sensor generates a plurality of inspecting signals according to a flickering intensity of the LCD panel and provides the inspecting signals to the timing control circuit. The timing control circuit prepares a plurality of compensating gradation voltages according to the inspecting signals and providing the compensating gradation voltages to the data driving circuit.
