Attaching the Touchscreen

Once you have verified all dimensions and checked that the bezel has plenty of clearance around the transducers and lands inside the sealing area, you are ready to install the touchscreen.

1Check room for cable routing:

•Route away from noise sources (flyback transformer, power supply, yoke, high voltage lead, etc.)

•Cable can be on either side.

•Avoid pinch points.

•Make up excess cable with tie wraps.

2Ensure the display and touchscreen and are clean before installation.

•Use black background to ensure fingerprints and smudges are not visible.

•Compressed air is best to remove dust.

3Use double-sided high tack adhesive tape3 on all four sides to attach the touchscreen to the display.

•3 mm thick for curved

•2 mm thick for flats > 15"

•1 mm thick for flats <= 15"

•Acts as dust seal as well as an adhesive. (Make a flat “T” in corners for dust seal.)

•Or substitute foam tape on two sides

•Or use metal frame on flats, but still use foam tape for dust seal.

3.Refer to “Elo Part Numbers” on page C-79 to ensure you are using the proper adhesive
