9.6 DC/DC Converter Part
9.6.1 Purpose
From 5V, Vs, and Va (from PSU), the DC/DC converter makes
5V, 15V, Vy, Vsc, 5Vf, and Va, which are essential for each
board.

9.7 FPC (Flexible Printed Circuit)
9.7.1 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 is double-sided (these have a pattern on
it).
• For Z board there is no pattern, single-sided, and Beta type
(all of copper surface).

9.8 FFC (Flat Flexible Cable)
9.8.1 Purpose
For connecting LOGIC signals between boards. There are two
types
• 0.5 mm pitch, 50-pin type.
• 0.5 mm pitch, 60-pin type.

9.9 TCP (Tape Carrier Package)
9.9.1 Purpose
To supply a waveform which is made by the X board to the
PDP, and to select an output pin that is controlled by TCP when
"on" or "off" (192 output pins per IC).
• TCP is package type, which is made by Direct Bonding
between IC and electrode film.
• It is more effective than Wire Bonding type by increasing
number of Data Driver IC output pins (96-pin -> 192-pins,
pitch < 80 µm).
