Abstract: A backlight unit using a microwave plasma ultraviolet lamp as a light source and a liquid crystal display including the backlight unit. The backlight unit for a liquid crystal display comprises a tube filled with discharge gas, a cavity resonator in which one end of the tube is inserted, a magnetron for generating microwaves and supplying the generated microwaves to the cavity resonator, a magnetron driver for driving the magnetron, and a phosphor layer for converting ultraviolet light generated in the tube into visible light.

Abstract: A lamp driving circuit includes a power-generating section, a distribution sensing section and a feedback control section. The power-generating section generates a lamp driving power to drive a plurality of lamps. The distribution sensing section divides the lamp driving power to the plurality of lamps. The distribution sensing section senses the lamp driving power to generate a feedback signal. The feedback control section checks whether or not the plurality of lamps is lit. The feedback control section blocks the feedback signal from being reflected in the lamp driving power before the plurality of lamps is lit.

Abstract: A backlight assembly having improved luminance uniformity of emitted light, and a display device having the backlight assembly, includes first and second lamps, a receiving container and a reflection plate. The first and second lamps are arranged on a bottom plate of the receiving container substantially parallel to each other and emit ultraviolet light rays. The reflection plate is fixed on the bottom plate under the first lamp and extends to a space above the second lamp. A fluorescent layer is formed on the reflection plate. The fluorescent layer converts the ultraviolet light rays emitted from the first and second lamps into visible light rays. Luminance uniformity of light emitted from the backlight assembly is improved and a display quality of the display device is improved.
