초록
In comparison with CCFL, LED can have more various colours. The research into BLU to raise colour reproducibility is actively proceeding by using RGB LED. On this study, Direct BLU was designed by white LED and RGB LED. According to the result of the experiment, the colour uniformity degree of BLU model using white LED is better than RGB LED BLU. On the other hand, the colour reproducibility of RGB LED BLU is better than white LED. The research showed that the uniformity of white LED is 81.7%and RGB LED is 70.01%.
