In addition to improving fundamental DST properties, the foam tape serves the following
purposes:
•
Holds the sensor in place on the display
•
Cushions the LCD and glass surfaces
•
Prevents dust and other contaminants from getting in between the LCD and sensor
surfaces
Practice Positioning the Sensor
The correct positioning of the sensor is extremely important. You should practice
positioning the sensor on the display until you are comfortable with how the sensor
should be aligned with the horizontal and vertical center of the display face.
1.
Place the display face-up on the foam pad, being careful of the components attached
to the rear of the display.
2.
Hold the sensor so the flex tail exits from the top. If you are unsure of the correct
positioning, contact your customer service representative to request a detailed
drawing.
3.
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. Do not pull tightly on the tail.
4.
Place the sensor onto the display and ensure that the sensor is straight and the
viewing area centered on the LCD.
Sensor Cleaning
Ensure the sensor is clean of debris and fingerprints on both sides before completing the
mounting process.
CAUTION
To reduce the risk of the potentially hazardous situations associated with the use
of isopropyl alcohol which may result in minor or moderate injury or property
damage:
Follow all instructions and recommendations in the alcohol manufacturer's Material
Safety Data Sheet and product label.
Use an isopropyl alcohol and water solution ratio of 50:50 to clean your sensor. You may
also use straight isopropyl alcohol.
It is important to avoid using any caustic chemicals on the sensor.
Always dampen the cloth and then clean the sensor.
Apply the cleaner with a soft, lint-free cloth. Avoid using gritty cloths.
Attaching the Sensor to the Display
Once you feel comfortable with the alignment and positioning of the sensor, you are
ready to permanently attach the sensor to the LCD.
