Abstract

Local control for high-quality 3D images is achieved while reducing circuit cost and extraneous radiation. A control signal is outputted to an LED backlighthaving a plurality of light emission areas for emitting light to a liquid crystal panelfrom the back for the respective light emission areas corresponding to a plurality of display areas included in the liquid crystal panelcapable of displaying a three-dimensional image by receiving a left-eye video signaland a right-eye video signal, the control signal controlling the intensity of each of the light emission areas according to the intensity of an image. Light emission intensity is determined based on the left-eye video signaland the parallax information or depth information of the image, and then information on the light emission intensity is outputted to the LED backlight
