LVDS Display Circuit

A low-voltage differential system (LVDS) carries all communication to the liquid crystal display (LCD).
The LVDS receives input from the control computer flat-panel interface and sends its data directly to
the display. The LVDS circuitry multiplexes the 32-TTL (transistor-transistor logic) signals from the
control computer into 8 low-voltage differential lines for signal fidelity. The LVDS signals are converted
back to TTL signals on the display CCA.
