PLANE LIGHT SOURCE USING WHITE LED AND LCD BACKLIGHT UNIT COMPRISING THE SAME

摘要

A surface light source using the white LED and the LCD backlight unit comprising the same are provided to simplify the manufacturing process using only white LED unit. Light-emitting diodes are arranged with a minimum distance from each other by adjusting the line feed pitch(D1), the row pitch(D2) and the arrangement angle between the white light-emitting diodes. A plurality of white light-emitting diodes(110) are isolated from the fixed interval. The LED unit made of polygon through the combination of white light-emitting diodes. The center(C) quantity of light of the LED unit becomes 80% or 120% of the value dividing the total quantity of light coming from each white light-emitting diode evenly.
