Figure 2.9 Attaching double-sided adhesive tape to the touchscreen

•Practice aligning the touchscreen on the LCD without removing the adhesive tape liner. The installation can tolerate some horizontal and vertical shift. However, rotational skew may interfere with proper mounting of the LCD touchscreen in the bezel.

•When you have a good feel for the placement of the touchscreen, clean the back side of the touchscreen and the face of the LCD. Avoid all contact between the cleaning solution and the mounting materials as the cleaner may cause the mounting materials to eventually release from the glass. Remove all lint with a brush or compressed air. Remove the liner from the adhesive tape and align the touchscreen on the display. Now press the touchscreen firmly against the LCD.

•Inspect your results carefully for alignment, trapped dust or lint, and a good seal between the touchscreen and LCD. If there is trapped lint, you may be able to remove it without removing the touchscreen by capturing it with a thin wire. Poke the wire through the adhesive tape, and stick the lint to the wire. Pull the lint back into the tape and embed it there.

•If you must remove the touchscreen from the LCD, cut the adhesive tape away with a sharp thin blade, such as an X-Acto knife. The touchscreen glass will probably break if you try to pull it off by a corner or an edge. Shave the old adhesive tape from the touchscreen and LCD with the knife. Adhesive residues can be removed with isopropyl alcohol, which will leave streaks and fingerprint smears. Use glass cleaner for the final cleaning prior to reapplication of new tape.
