DESCRIPTION
Under the control of the shift register data, OE1 or OE2 or
OE3, and DIO1 or DIO2, the driver outputs are VGG or VOFF
and change their value at the rising edge of FX
Power supply for TFT driver output low level
Negative power supply for Level shifters. Chip ground
Logic ground, Reference of the voltages
RL = “H” : X1 ĺ X256 (Shift left)
RL = “L” : X256 ĺ X1 (Shift right)

Output
Input
When XDON = “L” then the driver outputs are at the VGG
level independant of any other input or register value.
The start pulse is sampled at the rising edge of FX,
The carry pulse changes at the falling edge of FX.
When OEN = “H” then the associated outputs are set to VOFF
independent of the register data. This function is not
synchronized with FX.
Logic positive power
High voltage power and TFT driver output high level
