r61509v 26万色240rgb X 432点阵图形液晶非晶硅TFT面板控制器驱动程序

　　The R61509V is a single-chip liquid crystal controller driver LSI for a-Si TFT panel， incorporating RAM for a maximum 240 RGB x 432 dot graphics display， gate driver， source driver and power supply circuits. For efficient data transfer， the R61509V supports high-speed interface via 8-/9-/16-/18-bit ports as system interface to the microcomputer. As moving picture interface， the R61509V also supports RGB interface （VSYNCX， HSYNCX， DOTCLK， ENABLE and DB17-0）。 The power supply circuit incorporates step-up circuit and voltage follower circuit to generate TFT liquid crystal panel drive voltages. The R61509V’s power management functions such as 8-color display and shut down and so on make this LSI an ideal driver for the medium or small sized portable products with color display systems such as digital cellular phones or small PDAs， where long battery life is a major concern.
