240 Channel TFT Gate Driver with Internal Power IC
Power-supply voltage for liquid crystal(LC) driving
DDVDH – GND = 4.0 ~ 5.5 (V) (Driving for source driver liquid crystal output circuit
/ Driving for Vcom output)
VGH – GND = 9.0 ~ 16.5 (V) (Driving for gate driver)
VGL – GND = -4.0~ -14.0 (V) (Driving for gate driver)
VCL – GND = 0 ~ -3.3 (V) (Driving for VcomL , VcomL2 output)
Output voltage level
VDH – GND = 3.0 ~ (DDVDH-0.5) (V) (Reference power supply for source driver grayscale

voltages)
Vcom(2) – GND (Using for common voltage level)
VcomH(2) = 3.0 ~ (DDVDH-0.5) (V) (High-level common voltage in alternating driving)
Vcom L(2) = VCL + 0.5 ~ 1.0 (V) (Low-level common voltage in alternating driving)
Vcom(2) amplitude ( VcomH(2)-VcomL(2) ) = 6 (V) max.
