Function
Not internally connected.
Output of GPM circuit. This output directly drives the supply for the gate driver circuits.
Determines when the TFT LCD is on or off. This is controlled by the timing controller in
the LCD module.
VDPM pin is the enable signal for the GPM block. Pulling this pin high enables the GPM
while pulling this pin low disables it. VDPM is used for timing sequence control.
Reference input for gate pulse modulation (GPM) circuit. The voltage at V
DD
is used to set
the lower VGHM voltage.
Op-Amp analog power input.
Output of the Op-Amp.
Negative input terminal of the Op-Amp.
Positive input terminal of the Op-Amp.
Analog ground for the step-up regulator, LDO, and Op-Amp. Connect directly to DAP and
PGND beneath the device.
LDO output voltage feedback input.
LDO regulator output.
