11. PRECAUTIONS IN USING
11.1 Liquid crystal display (LCD)
The LCD panel is made up of glass, organic fluid and polarizer. When handling, please pay attention to the following items:
1) Keep the operation and storage temperature of the LCD within the range
specified in the LCD specification. Otherwise, excessive temperature and humidity would cause polarization degradation, bubble generation or polarizer peel-off.
2) Prevent it from mechanical shock by dropping it from a high place, etc.
3) Don’t contact, push or rub the exposed polarizers with anything harder than
HB pencil lead.
4) Avoid using chemicals such as acetone, toluene, ethanol and isoropylalcohol
to clean the front/rear polarizers and reflectors, which will cause damage to them.
5) Wipe off saliva or water drops immediately. Contact with water over a long
period of time may cause deformation or color fading. The LCM is assembled and adjusted with a high degree of precision.
6) Do not put or attach anything on the display area. Avoid touching the display
area with bare hand.
11.2 Precaution for handling LCD modules
The LCM is assembled and adjusted with a high degree of precision, do not applying excessive shocks to it or making any alterations or modifications to it, the following precautions should be taken when handing.
1) Do not drop, bend or twist the module.
2) Do not alter or making any modification on the shape of the metal frame.
3) Do not change the shape, the pattern wiring or add any extra hole on the PCB.
4) Do not modify or touch the zebra rubber strip(conductive rubber) with another
object.
5) Do not change the positions of components on the PCB.
11.3 Electro-static discharge control
Careful attention should be paid to control the electrostatic discharge of the modules, since the modules contain no. of CMOS LSI.
1) Make sure you are grounded properly when remove the module from its
antistatic bag. Be sure that the module and have the same electric potential.
2) Only properly grounded soldering iron should be used.
3) Modules should be stored in antistatic bag or other containers resistant to
static after remove from its original package.
4) When using the electric screw-driver is used, make sure the screw driver had
been ground potentiality to minimize the transmission of EM wave produced by commutator sparks.
5) In order to reduce the generation of static electricity, a relative humidity of
50-60% is recommended.

Page 29
DEM 240320E TMH-PW-N(A-TOUCH) Production Specification
11.4 Precaution for soldering
1) Soldering should apply to I/O terminals only.
2) Soldering temperature is 280+(-)10.
3) Soldering time 3-4 seconds.
4) Eutectic solder (rosin flux filled) should be used.
5) If soldering flux is used, be sure to remove any remaining flux after
finishing the soldering operation and LCD surface should be covered during soldering to prevent any damage to flux spatters.
6) When remove the lead wires from the I/O terminals, use proper
de-soldering methods, e.g. suction type de-soldering irons. Do not repeat wiring by soldering more than three times at the pads and plated though holes may be damaged.
11.5 Precaution for operation
1) Adjust liquid crystal driving voltage (Vo) to varies viewing angle and
obtain the contrast.
2) Vo should be kept in proper range stated in the specification. Excess
voltage will shorten the LCD life.
3) Response time is greatly delayed at low temperature. It will recover when
go back to normal temperature.
4) Condensation on terminals can cause an electrochemical reaction
disrupting the terminal circuit. Therefore it should be used under the relative condition of 50% RH.
11.6 Storage
When long term storage is required, following precautions are necessary:
1) Storage them in a sealed polyethylene bag (antistatic), seal the opening,
and store it where it is not subjected to direct sunshine, or to the light of
fluorescent lamp. If properly sealed, there is no need for desiccant.
2) Store them in the temperature range of -30~80 and at low humidity is
recommended.
