Handling of LCD Panels
1) The LCD display contains skin-irritating materials. If liquid materials flow out due to damages and comes in contact
with skin, wash the area under running water for at least 15 minutes.
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 afterimage. This is a basic characteristic
of the LCD display and not a malfunction.
In order to avoid afterimages 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 Screens
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 screens structural characteristics.
2) The touch screen is made of glass. Glass becomes easy to break if scratched. Please handle with care and avoid
glass from coming in contact other glass and hard objects.
3) Due to the characteristics of the touch screen, pressing a little outside the display area may be detected as the
coordinates of the edge of the touch screen. Please consider the above when designing the application.
4) Touch screen coordinates may shift due to aging or depending on its operating environment. Conduct calibration
of the touch screen to correctly set the coordinates.
5) Please be careful when handling the glass. The glasses are not chamfered and can easily cause injuries.
Handling of Projective 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) 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.
3) 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.
4) When designing applications, consider the fact that areas slightly outside the display might be read as a
coordinate due to the characteristics of the touch screen when touched.
5) Glass edge surface can easily cause injuries. Please handle with care.

■EM8 Model (Analog Resistive Touch Screens)
1) When applying sheets to the surface of the entire opening of touch screen surface.
Design and adjust the touch screen a little apart (app 0.3mm recommended) so the sheet does not press down
on the touch screen.
Please do not directly touch the edges of the panel openings to avoid damage to the LCD, Touch screen, and
tail of the FPC. If damaged, there is a possibility it may cause operation failure tothe display and/or touch
screen,
2) When Bezels come on top of the touch screen surface
Be sure to keep a clearance of 0.5mm or more between the inside of the bezel and the touch screen surface in order
to avoid input errors caused by strains of the bezel when hands are placed on it.
When placing cushions and/or dust-proof gaskets between the inside of the bezel and the upper electrode of the
touch screen, be sure to have allowance to absorb the expansion/contraction differences due to temperature change.
If cushions are pressed down strongly, the upper electrode of the touch screen will distort or bend and may affect
both the appearance and function.
Also, the cushions should always be placed within 1.0mm from the edge of the touch screen.

■EMG8 Model (Projective Capacitive Touch Screen)
If factors that change the electric fields, such as large capacitor, power supply units, LCD panels, and groundings
and other high dielectric constant materials are near the touch screen, the effect of the external factors will be
larger than the capacitance of input and have a negative impact on the coordinate detection mechanism.
1) When installing panel surface and touch screen to same surface.
・Keep distance of 2mm or more from the touch screen and more than 1mm from the FPC tail.
2) When bezels come on top of touch screen surface
・Material made of insulating resin is recommended for the bezel to put on top of the touch screen. Ensure a distance
of L2 between the touch screen and the bezel.
・Material made of insulating resin is recommended for the bezel to put on top of the touch screen. Ensure a distance
of L2 between the touch screen and the bezel.
・If a sheet metal bezel is used, capacitive coupling may occur with the sheet metal at the periphery of the active
area.
When designing a bezel using sheet metal or other metal material, ensure that the gap L2 between the touch screen
and the bezel is about 2 mm.
The FPC tail of the touch screen should be set as far away from metal as possible.
To prevent incorrect operation of the touch screen, the following dimensions should be secured.
L1 ≧ 2mm : Distance between the bezel surface/ touch screen
L2 ≧ 2mm : When using a sheet metal bezel, it is recommended to keep at least 2mm distance between the
touch screen and the backside of the bezel.

This is a calibration for projective capacitive touch screens.
The projective capacitive touch screen of the EMG8 has an auto-calibration function and will automatically calibrate
according to the environment in which is installed. However, please note it may not adapt to all installed environments.
but does not adapt to all the environments.
If the touch screen operations become unstable, please reconsider the environment in which is installed.
Coordinate Calibration
■EM8 Model (Analog Resistive Touch Screen)
This is a calibration for analog resistive touch screens.
Conduct calibration if there is a big misalignment of the pressed point and the detected coordinate.
Coordinate calibration can be performed from the set-up tools.
