Backlight unit and liquid crystal display with the same
View Patent ↗A backlight unit and a liquid crystal display device including such a backlight unit are provided. According to an embodiment, there is provided a backlight unit comprising a plurality of light emitting diodes (LEDs) for generating light, a printed circuit board (PCB) for controlling the LEDs, a transparent scattering plate provided with a scattering optical pattern for scattering the light from the LEDs, and a diffusing plate for diffusing the light scattered by the scattering plate.
1. A liquid crystal display device comprising:
a liquid crystal panel having upper and lower substrates between which a liquid crystal layer is formed;
a plurality of light emitting diodes (LEDs) for generating light;
a printed circuit board (PCB) for controlling the LEDs; and
a diffusing plate for diffusing the light generated from the LEDs; and
a plurality of diverters attached on a rear surface of the diffusing plate and having a glass plate on which a scattering material is doted, wherein the diverters respectively correspond to the LEDs.
2. The liquid crystal display device according to claim 1 , further comprising:
a reflecting plate for reflecting light directed toward the PCB.
3. The liquid crystal display device according to claim 1 , wherein the diverters are formed on portions of the rear surface of the diffusing plate, and corresponds to the LEDs.
4. The liquid crystal display device according to claim 2 , wherein the reflecting plate is formed of acryl or polyester.
5. The liquid crystal display device according to claim 1 , wherein the diverters are designed to scatter light emitted in a vertical direction of the LEDs.
6. The liquid crystal display device according to claim 1 , wherein the PCB is a metal core printed circuit board (MCPCB).
