Y-Drive Boards work as a path supplying
the Sustain and Reset waveforms
which are made in the Y-Sustain board
and sent to the Panel through Scan
Driver IC's.
The Y-Drive Boards receive a waveform
(Y-Drive) developed on the Y-SUS
board then selects the horizontal
electrodes sequentially starting at the
top and scanning down the panel.
Scanning is synchronized by receiving
Logic scan signals from the Control
board.
The 50PK950 uses 12 Driver ICs on
2 Y-Drive Boards commonly called
"Y-Drive Buffers" but are actually Gate
Arrays.
