摘要
通过理论分析与模拟验证，设计和制作了一款采用双侧边光式白光LED作为背光源的26 inch(1 inch=2.54 cm)液晶电视。选用的白光LED结构简单，性能优良。在实际制作中利用高效的驱动电路对白光LED单元进行驱动。模拟结果表明：此结构的白光LED背光源液晶电视亮度均匀性能够达到91%，色度均匀性达到85%，完全满足设计应用要求。
Abstract
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.
