AI Technical Summary

Problems solved by technology

Manufacturing costs are thus increased and the frequency at which LED substrates can be shared is reduced due to the size of the display screen
In addition, when a defect occurs in a part of the LED, the entire LED substrate should be replaced and it is difficult to deal with these defects

Abstract

A light emitting assembly, a backlight unit, and a display are provided. The light emitting assembly includes: light emitting modules, wherein the light emitting modules include: a substrate having an electrical connecting portion; and a plurality of light emitting units arranged on the substrate, and wherein the light emitting modules can be assembled using the electrical connecting portion. The light emitting assembly can be assembled using the light emitting modules comprised of independent blocks and thus, can be freely used regardless of the size of the display.

Description

[0001] This application requires the Korean Patent Application No. 10-2005-0086242 filed at the Korean Intellectual Property Office on September 15, 2005 and the U.S. Provisional Application No. 60 / 664,193 filed at the U.S. Patent and Trademark Office on March 23, 2005 The priority of, its disclosure is fully incorporated herein by reference. Technical field [0002] The present invention relates to a light emitting assembly, a backlight unit, and a display having the backlight unit, which can be easily assembled to be used as a light source according to the size of the display. Background technique [0003] Generally, a liquid crystal display (LCD) device, which is one type of flat panel display, is a light-receiving type display that does not emit light but uses incident light from the outside to form an image. LCD devices are used in notebook computers, desktop computers, LCD-TVs, and mobile communication terminals. LCD devices ...
