LIQUID CRYSTAL DISPLAY DEVICE FOR IMPROVING THE QUALITY OF DISPLAY USING A LIGHT-EMITTING DIODE PACKAGE WITH AN IMPROVED COLOR REPRODUCTION RATE

摘要

PURPOSE: A liquid crystal display device is provided to improve a color reproduction rate of a light-emitting diode package by forming a red pigment layer on the front side of a printed circuit board and obtain a screen of high quality.;CONSTITUTION: A plurality of light-emitting diode packages(LED packages)(102) are arranged on the lower part of a liquid crystal panel(LCD panel)(101). The multiple light-emitting diode packages supply the light to the liquid crystal panel. Multiple light-emitting diode packages comprise a blue-LED chip and a yellow fluorescent material on the blue-LED chip. The multiple light-emitting diode packages are mounted on the front of a printed circuit board(PCB)(103). A red pigment layer(104) is formed on the domain of the front side except for the mounted domain of the light-emitting diode package.;COPYRIGHT KIPO 2010
