Liquid crystal display device, and timing controller and signal processing method used in same

Abstract

A liquid crystal device is provided which is capable of being free from degradation of signal receiving sensitivity and/or malfunction without performing thinning-out and complementing on video signals of an electronic device having an embedded peripheral circuit to receive and transmit data. A stop period during which outputting of horizontal synchronizing signal made up of a video signal strobe signal STB and vertical drive clock signal VCK is stopped at least one time or more and for two horizontal periods or more during a display period in one vertical period is set by a control device (for example, timing controller). In this horizontal synchronizing stop period setting mode processing, a first signal (for example, status signal) indicating that the outputting of the horizontal synchronizing signal is in a stop state is transmitted to an electronic circuit (for example, peripheral circuit).
