  • Operating frequency up to 30MHz
  • Partial display function for low power consumption
  • Low-power operation supports:
  • Power saving function (standby mode)
  • Operating voltage
  • Applying voltage
  • IOVCC1/2 = 1.65 to 3.6V (interface I/O power supply, always IOVCC1 ≥ IOVCC2)
  • VCC = 2.4 to 3.6V (internal logic power supply)
  • VCI = 2.5 to 3.6V (analog power supply)
  • Generating voltage
  • VCI1OUT = Internal regulated voltage of VCI
  • VLOUT1 = 2 x VCI1
  • 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 S320 : V0 to V255 grayscale
  • Gate-less signal :
  • VGH to VGL level
