  • Patent number: 9361835
    Abstract: In the present liquid crystal display device, an LED output value correction section (513) included in an area-active drive processing section (5) corrects LED data Dbl obtained by an LED output value calculation section (512) with reference to a luminance correction LUT (13), such that the luminance in the area from an intermediate value to near a maximum value shifts to a higher degree. Thus, even if the backlight luminance is low (typically, the mean luminance of an input image is low), contrast ratio is enhanced, thereby preventing a tone jump (insufficient luminance) at high tone levels due to an insufficient backlight luminance.

    Abstract: A liquid crystal display device employing a scanning backlight scheme which reduces the degradation of display quality is provided. An image formation region is divided into a plurality of regions S1-Sn corresponding to scanning lines, where the region S1 corresponds to the uppermost scanning line, the region Sn corresponds to the lowermost scanning line, and n is a natural number of three or more. The liquid crystal display device includes a backlight 150 having a plurality of light emitting units configured to illuminate the respective regions. The light emitting units are turned on in synchronization with timings of writing a data signal. In the liquid crystal display device with the scanning backlight scheme, turn-on timings of the light emitting units of the regions S1-Si (i is a natural number of 1?i<n) are caused to be later than the respective timings of writing data in the regions.
