A backlight device for a liquid crystal display includes a substrate, and a plurality of white, red, green, and blue light emitting diodes arranged on the substrate.

Backlight device for liquid crystal display and method of fabricating the same

A backlight unit adapted to enhance brightness and reduce manufacturing time and costs is disclosed. The backlight unit includes a bottom cover with an opened upper surface, a plurality of light emission diodes arranged on an inner edge of the bottom cover, a light guide plate disposed parallel to the plurality of light emission diodes, and a diffusion sheet disposed on the light guide plate. The diffusion sheet is provided to have an overlapped area with a support main which is combined with the bottom cover. Also, a reflection material layer is formed on an upper surface of the diffusion sheet corresponding to the overlapped area.

Backlight unit and liquid crystal display device having the same

A backlight unit is adapted for increasing the brightness uniformity and life span of a light source, and a liquid crystal module using the same. A light unit includes a light source; a temperature sensor for sensing a temperature of the light source; a peltier device for increasing and decreasing the temperature of the light source; and a controller for controlling the peltier device in correspondence to an output of the temperature sensor.

Backlight unit and liquid crystal module

A backlight device for a liquid crystal includes a substrate, a light source including a first plurality of green light emitting diodes, a second plurality of blue light emitting diodes, and a third plurality of red light emitting diodes arranged along a first row direction on the substrate in an offset matrix-type configuration, wherein white light emitting diodes are disposed at both ends of the configuration of the green, blue, and red light emitting diodes.
