Abstract
This paper studies the current regulator of LED Backlighting system for LCD. The proposed regulator and a typical regulator are introduced. To find out the characteristics of two regulators, Prototype samples of LED Backlighting system are made. Both the proposed regulator and a typical regulator are compared with electrical, thermal and optical characteristics each viewpoint.
