Operating voltage
Applying voltage
IOVCC = 1.65 to 3.3V (interface I/O power supply)
VCC = 3.0 to 3.6V (internal logic power supply)
VCI = 3.0 to 3.6V (analogue power supply)
Generating voltage
VGH = 4.0 to 7.0V (gate circuit power supply, default = 5.2V)
VGL = -8.0 ~ -5.0V (gate circuit power supply, default = -7.0V)
VINT = -4.0 to -1.0V, default = -2.0V
VSUS = 2.1 to 5.0V, default = 3.5V
Source output swing range = 0.4 to 4.5V
Panel driving output
