초록

In this paper, we have designated a 42-inch RGB LED BLU, 80 % above illuminance. A desirable brightness performance was attained, by doing anti-parallel configuration, a fitting of LED's strip distance and a height of the top of LED to the back of the LCD. We get the 85.81 % of the brightness uniformity which has 12.8 mm away from LED's top and LCD's back and 51.41 mm of the same spacing between LED's strip in simulation and 82.24 % in experiment.
