Operator Display
18004
NCR
The 7454 is available with a 12.1-Inch TFT (active matrix) LCD.
Contrast control is set by software, using a digital potentiometer on the
Processor Board. The terminal does not have a user-accessible contrast
adjustment. Software can set a default value after reading the Panel ID.
Display contrast changes with temperature.
LCD Adapter Board
The signals from the LCD header on the Processor Board are brought
to the LCD on a harness. Since there are multiple pin configurations
and connector types being used on the LCD, a small adapter board is
used to receive the LCD harness and map the signals into the correct
pinout for the LCD panel. This board has a connector that plugs
directly into the LCD panel.
