: supply a waveform which made from X B/D to panel and select

a output pin that is controlled by COF when be on or off.

96 output pin per IC.

─

the more the resolution higher, the less spare space where

can set IC on it in B/D. without using IC PACKAGE,

we can use a BARE IC , so we can get IC with LOW COST

─

because we do not solder IC on PCB directly,

a soldering defect rate decrease.

* composition

1) FPC + Heat /Sink

⇒

FPC for COF must have a Low Spec decline with getting damp

2) CHIP resistor + CHIP CAPACITOR

3) BARE IC (STV7610A/WAF) + GOLD WIRE/AL WIRE

4) EPOXY MOLDING

9. COF (Chip On Film)

Bare IC

* 42 V6 COF is the same as 42V5.
