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 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 page to get the relative resister value

and voltage calculation method.
