The followings are applied to the viewing area only. Those in the non-viewing
area are ignored as long as the electrical performance of the touch panel is
normal. W=Width, L=Length, T=Thickness. Contamination that can be cleaned
using a soft cloth with ethyl alcohol does not apply to these inspection
criterion. But if an object is in the viewing area after rubbed by the soft
cloth to a direction 3 times longer, it is considered a linear foreign
object.
Inspection condition
The inspection shall be performed by using two 14W fluorescent lamps.
The panel shall be placed at 30cm away from eyes as shown below.

11-1. Storage
Store touch panels in boxes at storage temperature.
Please do not expose touch panels to a direct ray of the sun.
Do not give shock and vibration to the touch panels.
11-2. Unpacking
Open the box after checking the up/down indicator.
Please do not touch where FPC tails in order to avoid disconnection.
11-3. Handling
Use gloves and masks when handing touch panels.
Please do not hole FPC tails on handling touch panels .
Hold touch panels around outside of viewing area.
Please do not pile touch panels onto other touch panels.
Please do not put heavy objects on touch panels.
Clean off touch panels with soft clothes with alcohol when surface is dirty.
Please do not use organic solvents except alcohol.
11-4. Assembly
Please design housing which minimizes stress onto touch panels.
Please pay attention not to harm touch panels with your tools which may be
used for assembling.
Please pay attention not to create any stress to the heat-sealed tails.
11-5. Housing design
Keep the gap(over 0.3mm) between the touch panel and flat-panel display to
protect a display device.
Keep the gap(over 0.3mm) between the bezel edge and touch panel surface.
The reason is to prevent the bezel edge from contacting touch panel surface
which may cause a short with the bottom layer. We recommend the use of a cushion material between the touch panel and
the bezel.
The cushion material should be limited only on the busbar area.
If it is out of the busbar area, a short may occur.
11-6. Operation
Please do not operate touch panels by applying excessive force.
Please do not use a sharp things except finger or R0.8 polyacetal
We recommend calibration after long term use tip pen for input.
