LIQUID CRYSTAL DISPLAY DEVICE
摘要:
A liquid crystal display device of the present invention includes: a liquid crystal panel (1) capable of switching between a 2D display and a 3D display; a digital γ correction section (21) for changing a gamma characteristic of a video signal supplied to the liquid crystal panel (1); a backlight (2) for backlighting the liquid crystal panel (1), which backlight includes an LED serving as a light source; and a backlight driving section (13) for controlling driving of the backlight (2). When the 3D display is carried out on the liquid crystal panel (1), the backlight drive control section (13) controls the driving of the backlight such that luminance of the LED is higher than that for the 2D display, and the digital γ correction section (21) changes a gamma characteristic of a video signal such that (i) luminance on a low gray level side is lower than that for the 2D display and (ii) luminance on a high gray level side is higher than that for the 2D display. This makes it possible to increase luminance perceived by a user without increasing the number of LEDs.
