Light source unit, liquid crystal display having the same, and method thereof |
摘要 |
A light source unit which can minimize current differences between a plurality of light emitting diodes (“LEDs”) includes a printed circuit board (“PCB”) which includes an active region that emits light and an inactive region that accounts for a remainder of the PCB, an LED array which includes a plurality of LEDs that are arranged at regular intervals, and a current balancing circuit which is disposed in the inactive region, generates a plurality of current balancing voltages by uniformly adjusting current differences between the LEDs, and outputs the current balancing voltages. A liquid crystal display (“LCD”) including the light source unit, and a method of minimizing current differences between a plurality of LEDs are further provided.
