IMAGE DISPLAY DEVICE, CONTROL DEVICE FOR SAME, AND INTEGRATED CIRCUIT
摘要:
Disclosed is an image display device having improved image qualities, while reducing power consumption. A backlight unit (20) includes a plurality of light sources disposed so as to form a plurality of light emission regions. A liquid crystal panel (10) displays an image by modulating light emitted from the backlight unit (20) in accordance with light emission transmissivity. A control unit (40) controls the light emission luminance value of the backlight unit (20) for each light emission region, and controls a liquid crystal display device (1). The control unit (40) calculates the light emission transmissivity, on the basis of the distances between the pixels of the liquid crystal panel (10) and the reference position(s) in one or more light emission regions, the luminance value of light that arrives the pixels, said luminance value being determined on the basis of the controlled light emission luminance value, and the image signals inputted to the pixels.
