Optical Design of Side-Lighting WLED for LCD Backlight
Through theoretical analysis and simulation test, we design and fabricate a 26 inch (1 inch=2.54 cm) liquid crystal display television set (LCD TV) with two side white light LEDs (WLEDs) as backlights. The structure of the WLED is simple and the WLEDs perform excellent. In the actual fabrication, a highly efficient circuit is used to drive the WLED units. The simulation results show that the brightness uniformity of the LCD TV is 91% and the color uniformity is 85%, which completely satisfies the requests of design.
