12. Precaution for using LCD/LCM
LCD/LCM is assembled and adjusted with a high degree of precision. Do not attempt to make any
alteration or modification. The followings should be noted.
General Precautions:
1. LCD panel is made of glass. Avoid excessive mechanical shock or applying strong pressure onto
the surface of display area.
2. The polarizer used on the display surface is easily scratched and damaged. Extreme care should
be taken when handling. To clean dust or dirt off the display surface, wipe gently with cotton, or
other soft material soaked with isoprophyl alcohol, ethyl alcohol or trichlorotriflorothane, do not
use water, keytone or aromatics and never scrub hard.
3. Do not tamper in any way with the tabs on the metal frame.
4. Do not make any modification on the PCB without consulting DISPLAY.
5. When mounting a LCM, make sure that the PCB is not under any stress such as bending or
twisting. Elastomer contacts are very delicate and missing pixels could result from slight
dislocation of any of the elements.
6. Avoid pressing on the metal bezel, otherwise the elastomer connector could be deformed and
lose contact, resulting in missing pixels and also cause rainbow on the display.
7. Be careful not to touch or swallow liquid crystal that might leak from a damaged cell. Any liquid
crystal adheres to skin or clothes, wash it off immediately with soap and water.
Static Electricity Precautions:
1. CMOS-LSI is used for the module circuit; therefore operators should be grounded whenever
he/she comes into contact with the module.
2. Do not touch any of the conductive parts such as the LSI pads; the copper leads on the PCB and
the interface terminals with any parts of the human body.
3. Do not touch the connection terminals of the display with bare hand; it will cause disconnection
or defective insulation of terminals.
4. The modules should be kept in anti-static bags or other containers resistant to static for storage.
5. Only properly grounded soldering irons should be used.
6. If an electric screwdriver is used, it should be grounded and shielded to prevent sparks.
7. The normal static prevention measures should be observed for work clothes and working
benches.
8. Since dry air is inductive to static, a relative humidity of 50-60% is recommended.

PAGE: 12
DEM 320240J TMH-PW-N (A-TOUCH)
Production Specification
Soldering Precautions:
1. Soldering should be performed only on the I/O terminals.
2. Use soldering irons with proper grounding and no leakage.
3. Soldering temperature: 280°C+10°C
4. Soldering time: 3 to 4 second.
5. Use eutectic solder with resin flux filling.
6. If flux is used, the LCD surface should be protected to avoid spattering flux.
7. Flux residue should be removed.
Operation Precautions:
1. The viewing angle can be adjusted by varying the LCD driving voltage Vo.
2. Since applied DC voltage causes electro-chemical reactions, which deteriorate the display, the
applied pulse waveform should be a symmetric waveform such that no DC component remains.
Be sure to use the specified operating voltage.
3. Driving voltage should be kept within specified range; excess voltage will shorten display life.
4. Response time increases with decrease in temperature.
5. Display color may be affected at temperatures above its operational range.
6. Keep the temperature within the specified range usage and storage. Excessive temperature
and humidity could cause polarization degradation, polarizer peel-off or generate bubbles.
7. For long-term storage over 40°C is required, the relative humidity should be kept below 60%,
and avoid direct sunlight.
Limited Warranty
DISPLAY LCDs and modules are not consumer products, but may be incorporated by DISPLAY’s
customers into consumer products or components thereof, DISPLAY does not warrant that its LCDs
and components are fit for any such particular purpose.
1. The liability of DISPLAY is limited to repair or replacement on the terms set forth below.
DISPLAY will not be responsible for any subsequent or consequential events or injury or
damage to any personnel or user including third party personnel and/or user. Unless otherwise
agreed in writing between DISPLAY and the customer, DISPLAY will only replace or repair
any of its LCD which is found defective electrically or visually when inspected in accordance
with DISPLAY general LCD inspection standard . (Copies available on request)
2. No warranty can be granted if any of the precautions state in handling liquid crystal display
above has been disregarded. Broken glass, scratches on polarizer mechanical damages as well as
defects that are caused accelerated environment tests are excluded from warranty.
3. In returning the LCD/LCM, they must be properly packaged; there should be detailed description
of the failures or defect.
