摘　　要：一种新型DC-DC转换器可整合在使用多晶硅薄膜晶体管的2.2inQVGA级LCD显示板上。为了给显示板提供正负电源,采用了多相DC-DC转换器结构,同时减小了充电泵的工作频率。所以显示板工作信号频率低于20kHz,不需要外部时钟脉冲信号和电容。A novel DC-DC converter has been integrated on a 2.2in QVGA panel using poly-silicon thin film transistors. We have structure to supply the positive and negative adopted a multi-phase DC-DC converter voltage source for the panel, and decreased the operational frequency of the charge pump. Therefore, the frequency of panel controlling signal is lower than 20 kHz, and no external clock signals and capacitors are needed.
