Abstract

Official abstract text for this publication.

A liquid crystal display includes: a light source unit that includes a light-guiding plate with a light-exit plane partitioned into emission subsections, and one or plural sides, and light sources; a liquid-crystal-display panel that includes pixels, and modulates light emitted from the light source unit, thereby performing image display; and a display control unit that includes a partitioning-drive processing section generating each of a light-emission pattern signal and a partitioning-drive image signal, performs light-emission driving for each light source, and performs display driving for each pixel. The partitioning-drive processing section performs a gain correction of multiplying each pixel signal in the input image signal by a predetermined gain factor that is set so that a value increases as a pixel position of the pixel signal goes away from the light source, and generates the light-emission pattern signal and the partitioning-drive image signal, by using gain-corrected pixel signal.

First claim

Opening claim text (preview).

What is claimed is: 1. A liquid crystal display comprising: a light source unit that includes a light-guiding plate with a light-exit plane partitioned into a plurality of emission subsections which are independently controllable of each other, and one or a plurality of sides, and a plurality of light sources disposed at the side; a liquid-crystal-display panel that is configured to include a plurality of pixels, and modulates light emitted from the light source unit on the emis…
