4 Replacement Procedures
The LCD mask must not touch any part of the transparent area; it will cause unexpected
input.
Inside edge of the LCD mask must be between the transparent area and the operation
guaranteed active area. The LCD mask must not touch film in the transparent area.
We recommend the part that secures the touch panel to be an elastic material.
Do not glue or adhere the film surface onto the display frame e.g. in a manner film may be
peeled or sheared off if stressed by expanding/shrinking due to temperature change.
NEVER do so especially where the conductive-connection part of film and glass;
electrical connection between FPC and touch panel will be deteriorated.
When aligning touch panel, do so by the glass outline, not by the film outline. Aligning by
the film will cause Newton ring to appear, unexpected input to occur and electrical
connection between FPC and touch panel will be deteriorated.
The end part of glass and film (marked as "*" in the following figure 'Installation
Example') have naked conductors.
Be sure to design the construction not to touch any conductive material on the parts
marked with "*".
