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
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 50PJ350 uses 8 Driver ICs on
2 Y-Drive Boards commonly called
“Y-Drive Buffers” but are actually Gate
Arrays.
