11 Handling Instruction
11.1 Assembling the module
1) Be sure to design the cabinet so that the module can be installed without any extra
stress such as warp or twist.
2) Please power off the module before you connect or disconnect input connector.
3) Make sure to connect module’s metal shield case to GND of DCDC converter
circuit.
If its connection is not made perfectly, some of the following problems may occur.
a) Increase of noise caused by backlight
b) Unstable output from DCDC converter circuit
c) Possibly over-heat in some section
11.2 Instruction for assembling
1) Since the front polarizer is easily damaged, pay attention to avoid rubbing with
something hard or sharp.
2) How to eliminate dust on polarizer.
・Blow dust away by N2 blower having measures of electrostatics
・Since the front polarizer is easily damaged, wiping dust off is not adequate.
If the polarizer is soiled, it is suggested to peel dust off by using adhesive surface
of adhesive tape.
3) When the metal section [shield case or shield back case] is soiled, wipe it off with dry and
soft cloth. If not so easy, breathe upon it then wipe off. If the water droplet or fat is left for
long term, it may cause stain or tarnish, it should be wipe off immediately.
4) Since TFT-LCD panel is made of glass substrate, dropping the panel or banging it against
hard objects may cause cracking or fragmentation.
5) Since CMOS LSIs are incorporated in this module, please pay special care to electrostatic
while handling it, and earth human body.
11.3 Caution in product design
1)The notes and cautions below should be followed when product is designed with this
module.
2)The module should be protected with cover to prevent salt content and/or water droplet.
Take enough shielding countermeasure not to interfere to peripheral electronic device.
3) If a minute particle enters in the module and adheres to an optical material, it may cause
display
non-uniformity issue, etc. Therefore, fine-pitch filters have to be installed to cooling and
inhalation hole if you intend to install a fan.
4) The LED used for this product is very sensitive to the temperature. Luminance decreases
rapidlywhen it is used for a long time under the environment of the high temperature.Please
consult our company when it is used under the environment like the above mentioned.
