1. When the RGB interface is not used, please shorted the VSYNC, HSYNC, DOTCLK  
and ENABLE to IOVCC or GND.  
2. When the SPI interface is not used, the SDI is shorted to IOVCC or GND, and  
let SDO as open.  
3. The Schottky barrier diode shall be added for VGL and VGH pins.  
4. If the voltage of interface is 1.8V, the IOVCC is connected to 1.8V and the
