IMAGE DISPLAY DEVICE AND ITS CONTROL CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide an image display device and its control circuit that can accurately drive a plurality of image display panels at the same time with simple constitution. SOLUTION: A timing controller 11 of a control circuit 10 is provided with two horizontal driving signal generating sections 12 and 13 which generate and output individual horizontal start signals STH1 and STH2 and horizontal clock signals CKH1 and CKH2 to two liquid crystal panels 20 and 30 which are driven at the same time by the control circuit 10. A phase difference corresponding to the delay time difference of signal transmission between the liquid crystal display panels 20 and 30 is provided between output periods of the horizontal start signals STH1 and STH2 and horizontal clock signals CKH1 and CKH2 of both the horizontal driving signal generating sections 12 and 13.
