50PX60 Panel Drive
The D board is responsible for displaying the picture on the screen. It
provides the scan, sustain and data drive signals. The scan pulses are
output to the SC board. The sustain pulses are output to the SS board. The
data drive signals are output to the C1, C2, C3, C4, C5 and C6 boards. The
C1, C2 and C3 boards buffer the data drive signals that are applied to the
upper half of the panel; The C4, C5 and C6 boards buffer the data drive
signals that are applied to the lower half of the panel.
The SC board is responsible for the generation of the scan pulses. Scan
pulses are used for initialization and selection of the pixels.
The SU and SD boards are de-multiplexer boards that are responsible for
converting serial data output of the SC board into parallel data to drive the
panel.
The SS board is responsible for the generation of the sustain pulses. Sustain
pulses are used to initialize and control the brightness of the screen.
The SS2 and SS3 boards are extension (connector) boards used to connect
the SC board to the panel.
