Operating voltage
Applying voltage
IOVCC = 1.65 to 3.3V (interface I/O power supply)
VCC = 2.4 to 3.3V (internal logic power supply)
VCI = 2.5 to 3.3V (analogue power supply)
Generating voltage
VCI1OUT = Internal regulated voltage of VCI
VLOUT1 = 2 x VCI1OUT
VREG2OUT ≥ 4.5V @VCI = 2.8V (typical)
VREG1OUT = 4.2V @VCI =2.8V (typical)
VLOUT2 = 3, 4 x VCI1OUT  VGH (4.6 ~ 6.0V)
VLOUT3 = -3, -4 x VCI1OUT  VGL (-7.8 ~ -6.4V)
VINT = -3.0 ~ -1.25V
Panel driving output
S1 to S960 : V0 to V255 grayscale
Gate-less signal
VGH to VGL level
