Low -power consumption architecture

Low operating power supplies:

IOVcc = 1.65V ~ 3.3 V (interface I/O)

Vcc = 2.4V ~ 3.3 V (internal logic)

Vci = 2.5V ~ 3.3 V (analog)

LCD Voltage drive:

Source/VCOM power supply voltage

DVDH - GND = 4.5V ~ 6.0

VCL – GND = -2.0V ~ -3.0V

VCI – VCL ≦ 6.0V

Gate driver output voltage

VGH - GND = 10V ~ 20V

VGL – GND = -5V ~ -15V

VGH – VGL ≦ 32V

VCOM driver output voltage

VCOMH = 3.0V ~ (DDVDH-0.5)V

VCOML = (VCL+0.5)V ~ 0V

VCOMH-VCOML ≦ 6.0V
