Teledyne API T802 Paramagnetic O
The LVDS (low voltage differential signaling) transmitter board converts the
parallel display bus to a serialized, low voltage, differential signal bus in order to
transmit the video signal to the LCD interface PCA..
The front panel touchscreen/display interface PCA controls the various functions
of the display and touchscreen. For driving the display it provides connection
between the CPU video controller and the LCD display module. This PCA also
contains:
 power supply circuitry for the LCD display module
 a USB hub that is used for communications with the touchscreen controller
and the two front panel USB device ports
 the circuitry for powering the display backlight
