TFT LCD Source Driver

Power on/off sequence:

This IC is a high-voltage LCD driver, so may be damaged by a large current flow when an incorrect power sequence is used.

First connecting the logical power, Vcc & GND and then the drive power, AVDD&AVSS with V1~V10 as the last is the

recommended sequence. When shutting off the power, first shut off the drive power and then the logic system, or turn off all

power simultaneously.

Relationship between input data and output voltage

The figure below shows the relationship between the input data and the output voltage with the polarity. The range of

V1~V5 is for positive polarity, and V6 ~ V10 for negative polarity. Please refer to the following pages to get the relative resistor

value and voltage calculation method.
