What's Inside?
LCD/Touchscreen and Mag Stripe Reader Assembly
Low Voltage Differential Signalling (LVDS) Receiver Board
This board, used only with the Samsung LCD, attaches directly to the panel
and fastened to the LCD bracket. It consists of U1, an DS90CF364 LVDS
Receiver. The receiver converts LVDS data streams generated by the system
board LVDS transmitter into 21-bits of CMOS/TTL data compatible with the
LCD Panel. The Sharp LCD incorporates the LVDS receiver internally;
therefore a separate receiver board is no longer required. A new interface cable
between the system board and LCD panel is required.
Backlight Inverter Board
The Backlight Inverter Board is mounted to the LCD bracket. Both the
Samsung and Sharp LCD panels use the same backlight inverter board. It
receives +10.4VDC and a Pulse Width Modulation (PWM) signal from the
system board to control backlight brightness.
Magnetic Card Reader
The 3-track serial interface magnetic card reader assembly is mounted in the
mag stripe channel on the top cover with two brackets. The interface cable
attaches to a modular connector located on the system board. The mag card
reader cover is shaped in the form of a trough to divert liquid spills into a slot
in the base, away from the system board.
