摘要
介绍了一款LED(发光二极管)背光源的驱动设计方案,并对LED的连接方式进行了分类,讨论串联、并联及混联电路的优缺点。最后结合15in面板,设计了一款混联的LED控制电路并给出实验测试结果。
The connections of LEDs for the LCD backlight were classified. The advantage and disadvantage of series and parallel or the mixture connections were discussed. According the analysis, a LED driver was designed with mixed connected LEDs and using this driver circuit a backlight for 15 inch TFT-LCD module was prepared and tested.
