SC Board Explanation

Figure 29
The SC Board consists of buffers and drivers used to generate the scan signals for the
PDP panel. The buffers provide isolation between the D board and the drivers.
Connector SC20 provides the drive voltages (140V, 100V and 18V) as well as the
trigger signals to switch the FET transistors. The D board switches the FETs on and off
to create the distinctive scan signal. Each trigger signal switches a drive FET creating a
portion of the waveform. For example, applying the CPH signal to the 140V FET creates
the peak portion of the waveform, see figure 29.
