When cleaning the glass, be careful near the corner components – these are active
electrical elements. Do not drag the cleaning cloth over them. Do not spray cleaner
directly onto the sensor. Spray the cloth first, then wipe.
Installation Considerations
Before beginning the installation, a few design considerations should be reviewed.
Planning will help to ensure a successful installation.
Note:
The DST sensor works exclusively with a mated DX123 controller for optimal
performance. Be sure to match the serial number on the sensor with the serial number on
the controller throughout the integration process.
•
Perform a bench test of the hardware to ensure functionality before you start.
•
Before installing the sensor, be sure to account for the space needed by the sensor
and its flex tail.
•
When installing the sensor, be careful not to route the sensor flex tail and power
wires near the backlight inverter or power supply of the LCD.
•
Ensure that nothing comes in contact with the sensor – it should be mechanically
decoupled from the display frame and bezel by the recommended foams.
•
The bezel may need to be modified to accommodate the sealing gasket and sensor.
When trimming the bezel, make sure that the mechanical integrity of the display is
not compromised.
•
If it is necessary to remove the sensor from the display after it has been attached, do
not pry it off. Carefully follow the instructions given in Removing the Sensor.
•
Be sure to follow solvent manufacturer's precautions and directions for use when
using any solvents. Follow manufacturer’s directions for suitable chemicals for your
display.
•
Ensure that the integration design does not subject the flex tail bond area to pinch
points and/or mechanical stresses.
•
Because the sensor traces are electrically active, they should not come in contact
with any conductive materials. Avoid contact with metal brackets, conductive bezel
paint, etc.
•
The sensor flex tail is designed to be flexible, and it may be creased once in a single
direction, in multiple locations along the flex tail and then secured in place with a
light adhesive tape.
•
When reassembling the sensor and bezel, do not over-tighten any one corner. Do not
over compress the sealing gaskets. 3M recommends 30% compression. Pressure
should be evenly distributed across the sensor.
•
Make sure there are no obstructions in contact with the sensor; check ribs, fins, and
standoffs.
