1. Key element within FPD (Flat Panel Display) products:
TFT：Thin Film Transistor, driver device of display control of an FPD product.
Fig1. Typical TFT structure of an sub-pixel of LCD FPD product
2. ESD sensitivity of FPD products in front-end FPD manufacturing:
TFT device exhibit highly susceptibility to high electric fields and may be damaged by following ESD events.
Fig2. Field susceptibility of TFT array
3. High charging risks in FPD manufacturing:
Glass substrate of FPD products is quite easily highly charged up.
