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 connection sequence is to first connect the logical power, Vcc & GND and then connect the drive power,
AVDD&AVSS with V1~V10. 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 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 resistors value and
voltage calculation method.
