NT3966
TFT LCD Source Driver
Power on/off sequence:
This IC is a high-voltage LCD driver, so it may be damaged by a large current flow when an incorrect power sequence is used.
The recommended sequence should be: digital power (Vcc&GND)è logic signals èanalog power (AVDD&AVSS) èGamma
correction reference voltage(V1~V10). Reverse this sequence to shut down, or turn off all signals and power simultaneously.

Relationship between input data and output voltage
The figure below shows the relationship among the input data and the output voltage and the polarity. The range of V1~V5 is
for positive polarity, and V6 ~ V10 for negative polarity. Please refer to the following page to get the relative resistor value and
voltage calculation method.
