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.
