Handling of LCD Panels
(1) The LCD display contains skin-irritating materials. If liquid materials flow out due to damage and comes
in contact with skin, wash the area under running water for at least 15 minutes. If it gets into the eyes,
wash under running water and consult a doctor.
(2) The LCD display might have uneven brightness according to the contents being displayed. This is not a
malfunction.
(3) Minute spots (dark or bright) may occur in the LCD display elements. This is a basic characteristic of the
LCD display and not a malfunction.
(4) When LCD display is viewed outside the specified view angel, the color might seem different. This is a
basic characteristic of the LCD display and not a malfunction.
(5) When displaying a same image for a long period of time, it might cause an image lag. This is a basic
characteristic of the LCD display and not a malfunction.
In order to avoid image lags, please follow the below procedures:
1.
When leaving the same image displayed, use the” display off” function.
2.Change the image displayed periodically and do not display the same image for a long period of time.

Handling of Resistive Touch Screen
(1) Please be warned that applications that require for one point to be pressed for a prolonged time may
cause failures due to the touch screen's structural characteristics.
(2) The touch screen is made of glass. Glass becomes easy to break if it gets scratched. Please handle as
not to hit glass or hard objects
(3) Due to the characteristics of the touch screen, pressing a little outside the display area may detect it as
the coordinates of the edge of the touch panel. Please consider the application carefully and design the
application.
(4) Touch screen coordinates may shift due to aging or depending on its operating environment. Conduct
calibration of the touchscreen to correctly set the coordinates.

Handling of Projected Capacitive Touch Screen
1)
If elements that change ambient environments or electric fields (capacitors with large capacity, power units,
and materials with high permittivity such as metals) are set close to the product, it might have impact to the
coordinate detection. Make sure to keep a good distance from the above unstable elements as much as
possible when designing.
2)
Due to the characteristics of the touch screen, its functions might become unstable according to the
environment it is installed. For correct operations, perform sensitivity sensor calibration when building into a
device.
Also if at any time the touch screen operation become unstable due to changes in environment or
installation conditions, perform sensitivity sensor calibration.
3)
The touch screen surface is made of glass. Glass is subject to break once scratched. Please handle with
care and avoid glass from contacting other glass and hard objects.
4)
Touch screen may not operate correctly when there is moisture on the surface.
When moisture is detected on the touch screen surface, please wipe it dry before use.
5) When designing applications, consider the fact that area slightly outside the display might be read as a
coordinate due to the characteristics of the touch screen when touched.
