摘要： A liquid crystal display includes: a signal controller which converts a first image signal having a first gray level based on an original gamma coefficient into a second image signal having a second gray level based on a target gamma coefficient; a liquid crystal panel connected to the signal controller and which displays an image based on the second image signal; and a light-emitting unit connected to the signal controller and which provides light to the liquid crystal panel. The target gamma coefficient is less than or equal to the original gamma coefficient, and a luminance of the light provided by the light-emitting unit is adjusted by the signal controller to minimize an amount of luminance distortion of the image.

摘要： A light-emitting module includes a light guide plate and a light source unit in accordance with an embodiment. The light guide plate include an upper surface, a lower surface facing the upper surface, a plurality of side surfaces connecting the upper surface and the lower surface, and a cross-sectional surface connected to at least one of the side surfaces. The light source unit includes a substrate disposed in correspondence with the cross-sectional surface and a point light source mounted on the substrate to emit light to the cross-sectional surface. Thus, light-emitting efficiency may be enhanced and the arrangement of point light sources may be optimized, so that a required amount of emitted light may be obtained using a small number of the point light sources. In addition, uniformity of luminance and heat-radiating efficiency may also be enhanced.
