FPC (Flexible Printed Circuit)
9.9.1
Purpose
To supply a driving waveform to the PDP by connecting a PAD
electrode of the PDP with a PWB (Y and Z boards).
•
There are two types of this for the Y board: One is single-
sided, the other double-sided (these have a pattern on it).
•
For Z board there is no pattern, single-sided, and Beta type
(all of copper surface).
