2.5.1 Using the TFT LCD Display Panel
The ADS is equipped with a Sharp LQ035Q7DB02 touch control enabled TFT LCD display assembly. The
ADS documentation CD contains specifications for the TFT LCD component.
CAUTION
Make sure that the input power to the main board is disconnected or
switched off before connecting the LCD module. Connecting the module
with power applied can damage the LCD module and/or the main board.
To use the TFT LCD display, connect the 34 conductor ribbon cable supplied with the ADS from J11 on
the LCD module to P7 on the Base board.
The potentiometer VR1, which is to the left of the LCD panel just below J11, controls flickering of the
display screen. This control is set at the factory and normally does not require adjustment. However, if the
TFT LCD display flickers, you may adjust VR1 to stabilize the display. Use a suitable flat head or phillips
head screwdriver. Because the adjustment is normally done with power applied, we recommend use of a
plastic blade tool.
