AI Technical Summary

Benefits of technology

The design enhances color uniformity by reducing temperature variations around the point light source assemblies, resulting in more consistent luminance and improved display characteristics.

Problems solved by technology

The change of emitting efficiency of the LEDs results in deterioration of display characteristics of liquid crystal displays.
For example, the emitting efficiency of a red LED changes substantially according to changes in a surrounding temperature, and color spots appear due to decreased color uniformity for each region.
The decrease in color uniformity occurs because the surrounding temperature is not uniform for each region of the liquid crystal display.

Abstract

A liquid crystal display includes a light guide plate that guides incident light, a first point light source assembly including first point light source elements that provide the light to the light guide plate and a first support substrate having the first point light source elements, the first point light source assembly being disposed at one side of the light guide plate, a second point light source assembly including second point light source elements that provide the light to the light guide plate and a second support substrate having the second point light source elements, the second point light source assembly being disposed at the other side of the light guide plate, a liquid crystal panel assembly disposed on the light guide plate that displays image information, and a lower container that accommodates the light guide plate, first and second point light source assemblies, and liquid crystal panel assembly.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional of U.S. patent application Ser. No. 11 / 944,012, filed on Nov. 21, 2007, which in turn claims priority from Korean Patent Application Nos. 10-2006-0115165 and 10-2006-0123917 filed on Nov. 21, 2006 and Dec. 7, 2006, respectively, the disclosures of which are incorporated herein by reference in their entireties.BACKGROUND OF THE INVENTION[0002]1. Technical Field[0003]The present disclosure relates to a display, and more particularly to a liquid crystal display including a point light source assembly.[0004]2. Discussion of the Related Art[0005]Liquid crystal displays are widely used flat panel displays. A liquid crystal display includes two substrates with electrodes and a liquid crystal layer interposed between the substrates. The liquid crystal display rearranges liquid crystal molecules in a liquid crystal layer by applying a voltage to electrodes to control the amount of light passing through the liquid c...
