    Why most of the TFT source driver use 2.5~3.6v device for its digital part?

    Re: TFT Source Driver The main power supply is 2.5~3.6V. But there is LDO regulator (1.8V) inside the chip. It will provide 1.8V power for internal logic/memory, etc.

    use resistor esd Diffusion resistor can spread heat very quickly while poly resistor can not since oxide is arround poly. Poly resistor is more easy to be burnt than diffusion resistor at ESD zapping.
