TM Series Instruction Manual iv
Handling of LCDs
1) The LCD contains skin-irritating materials. If liquid materials flow or spill out due to
damages and comes in contact with the skin, immediately wash the area under running
water for more than 15 minutes and consult a physician. If it gets in the eyes, rinse your eyes
immediately under running water and consult a doctor.
2) The LCD might have uneven brightness depending on the contents being displayed.
Please note that this is not a malfunction.
3) Minute spots (black or bright) may occur in the LCD elements. Please note that this is not a
malfunction.
4) When the display of the LCD is viewed from outside the specified viewing angle, the
displayed color might seem different. Please note that this a basic characteristic of the LCD.
5) When a same image is displayed for a prolonged period of time, it may remain as an
afterimage. Please note that this is a basic characteristic of the LCD.
To avoid afterimages, change the display image periodically and avoid displaying the same
image for a prolonged period of time.
Handling of Projected Capacitive Touchscreens (TMG)
1) Changes in the surrounding environment and/or elements that change the electric field,
such as capacitors with large capacitance, power supply units, metals, and other materials
with high dielectric constants are near, it may affect the coordinate detection. Keep as
much distance as possible from those unstable elements mentioned above when designing.
2) Connect the FG (Frame GND) of the TM main unit to FG (Field GND). Touchscreen
operation may become unstable.
3) Touchscreen operation may become unstable depending on the installation environment
due to the characteristic of the touchscreen. For correct use, please perform calibration of
the sensor sensitivity of the touchscreen when installing the equipment. For details, please
refer to “4.4 Calibation”.
4) Although the touchscreen is covered with tempered glass, please be careful when handling
as it may break when struck by hard objects.
5) The touchscreen may cause malfunction if there are drops of water on the surface of the
touchscreen. Please wipe it dry before use.
6) Due to the characteristics of the touchscreen, touching slightly outside the display area
may be detected as coordinates of the edge of the touchscreen. Please take this into
consideration when designing applications.
Handling of Analog Resistive Touchscreens (TMH)
1) Applications that require a point on the touchscreen to be pressed for a long time may cause
failures due to its structural features. Please be careful.
2) The touchscreen is made of surface film and tempered glass. There is a possibility of the
touchscreen becoming inoperable due to cracks and/or other damages to the surface film.
Also, the tempered glass can easily damage if scratched. Please handle the touchscreen so
it does not come in contact with hard objects.
3) Due to the characteristics of the touchscreen, touching slightly outside the display area may
be detected as the coordinates of the edge of the touchscreen. Please take this into
consideration when designing applications.
4) The coordinates of the touchscreen may shift over time or depending on the environment of
use.
If the coordinates shift, please perform calibration (coordinate correction). For details, please
refer to “4.4 Calibation”.
5) Due to the structure of the touchscreen, sealing material may be visible at the edge (upper
right corner when viewed from the front) of the touchscreen.
Please refer to the shipping standards for details. (Please contact our sales representatives.)
