Recommended Resistive Touch Screen Assembly Structure

<Mounting Notes>

• Bezel edge must be positioned in the area between the active area and viewing area (L1a).
  (Otherwise the bezel may press the touch screen and cause input if the edge enters the active area)
  The area within 2mm from the insulation area is structurally weak for the pressure, especially for pen use.
  The film may be forcibly bent and may cause defection.
  This area must be protected by the bezel and input must be avoided.
• A gap of approximately 0.5mm(L2) is needed between the bezel and the touch screen surface.
  It may cause unexpected input if the gap is too narrow.
• If a cushion is used between the bezel and the touch screen surface, the cushion must be free enough to absorb the expansion and contraction difference between the bezel and the touch screen surface.
  If the cushion is squashed to hard, the expansion and contraction difference may cause the distortion to the touch screen surface.
  The cushion must be positioned more than 1mm(L3) outward from an inside of the insulation area.
  (Please see the above structure)
• In case water-proof structure is necessary, use rubber materials as a cushion in a window frame form.
• Do not fix the front bezel and the touch screen surface with adhesives.
