Surface light source using LED and backlight unit having the surface light source
摘要：
A surface light source using LEDs is provided. The surface light source includes a substrate having a plurality of divided regions, a plurality of red, green and blue LEDs arranged on each divided region in a predetermined arrangement structure, and a plurality of LED driving units each having red, green and blue LED driving circuits for respectively driving the red, green and blue LEDs. Identical color LEDs in each divided region are interconnected in series. The series connections of the red, green and blue LEDs in one divided region are respectively connected to the series connections of the red, green and blue LEDs in one or more other divided regions in parallel. The parallel connections of the series connections are connected to corresponding color LED driving circuits.
