IMAGE DISPLAY DEVICE AND IMAGE DISPLAY METHOD

摘要

An LED output value correcting unit (513) included in an area active drive processing unit (5) of a liquid crystal display corrects LED data Dbl determined by an LED output value calculating unit (512) by referring to a brightness correction LUT (13) such that the brightness of the LED data in the range of an intermediate value to approximately the maximum value shifts to higher brightness. This leads to an improvement in the contrast ratio even when the brightness of a backlight is low (typically, when the average brightness of input images is low), and can prevent a tone jump (insufficient brightness) at high tones caused by insufficient brightness of the backlight.
