9.5
Y Sustain Board
9.5.1
Purpose
Generates Sustain waveform, Reset, Vsc (Scan) and -Vy
voltages, and supplies them to the Y DRIVE board.
Figure 9-5 Y Sustain board
9.5.2
Main Components
IPM, diodes, electrolytic capacitors, and FETs.
9.6
Y Drive Board
9.6.1
Purpose
•
To supply Sustain, Reset waveform, made by the Y-SUS
board, to the PDP through the SCAN DRIVER IC.
•
To supply a waveform that selects the horizontal
electrodes (Y SUSTAIN electrodes) sequentially.
–
Potential difference is 0 V between GND and Vpp of
the DRIVER IC during the SUSTAIN period.
–
Generates a potential difference between GND and
Vpp only during the SCAN period.

9.7
Z Sustain Board
9.7.1
Purpose
To make the SUSTAIN and ERASE pulses that generate
SUSTAIN discharge in the panel by receiving LOGIC signal
from CONTROL board. This waveform is then supplied to the
panel through FPC (Z).
9.7.2
Main Components
IPM, FET, DIODE, electrolytic capacitor, and E/R coil.
