 Low -power consumption architecture
 Low operating power supplies:
 VDDI = 1.65V ~ 3.3V (logic)
 VCI = 2.5V ~ 3.3V (analog)
 LCD Voltage drive:
 Source/VCOM power supply voltage
 AVDD - GND = 4.5V ~ 5.5V
 VCL - GND = -2.0V ~ -3.0V
 Gate driver output voltage
 VGH - GND = 10.0V ~ 20.0V
 VGL - GND = -5.0V ~ -15.0V
 VGH - VGL 32V
 VCOM driver output voltage
 VCOMH = 3.0V ~ (AVDD – 0.5)V
 VCOML = (VCL+0.5)V ~ 0V
 VCOMH - VCOML 6.0V
 Operate temperature range: -40 to 85
 a-Si TFT LCD storage capacitor : Cst on Common structure only
