BACKLIGHT UNIT

摘要

PURPOSE: A lighting system is provided to improve an optical property by constantly maintaining a brightness distribution using a light emitting device module and a pattern of a light guide panel. CONSTITUTION: A fixed groove(131) is formed on a circuit board(133). A resistive device(135) corresponds to the fixed groove. A light emitting device array is arranged on the circuit board with a line type. A light emitting device module(130) includes at least one resistive device which is arranged in a line of the light emitting device array. A light guide panel guides light emitted from the light emitting device module. A pattern of the light guide panel is embossed or engraved.
