2. Handling Instruction
2.1 Precaution in use of LCD Module
2.1.1. LCD panel is made of glass. Avoid excessive mechanical shock or applying strong
pressure on the surface of display area.
2.1.2. 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 isopropyl alcohol, ethyl alcohol, do
not use water, ketone or aromatics and never scrub hard.
2.1.3. Store the panel or module in a dark place where the temperature is 20±5and the
humidity is below 60% RH.
2.1.4. Keep LCD panels away from direct sunlight, also avoid them in high-temperature & high
humidity environment for a long period.
2.1.5. Do not input any signal before power is turned on.
2.1.6. 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.
2.1.7. To control temperature and time of soldering is 320±10and 3-5 sec.
2.1.8. EL manufactured from the organic film, and easily affected by temperature, humidity
and other environmental impact. Long-term placement in a place will cause low quality of
the case. Therefore, unpack the cartons and start the production with the LCM within
three months after the reception of them.
2.2 Static Electricity Precautions:
2.2.1. The LCD module contains a C-MOS LSI. People who operate the LCM should wear
ESD protection equipment to prevent ESD hurt on products.
2.2.2. 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.
2.2.3. Do not touch the connection terminals of the display with bare hand; it will cause
disconnection or defective insulation of terminals.
2.2.4. The modules should be kept in anti-static bags or trays for storage.
2.2.5. Only properly grounded soldering irons should be used.
2.2.6. If an electric screwdriver is used, it should be grounded and shielded to prevent sparks.
2.2.7. The normal static prevention measures should be observed for work clothes and
working benches.
2.2.8. Since dry air is inductive to static, a relative humidity of 50-60% is recommended.
2.3 Operation Precautions:
2.3.1. 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.
2.3.2. Driving voltage should be kept within specified range; excess voltage will shorten
display life.
2.3.3. An electrochemical reaction due to direct current causes LCD deterioration, Avoid the
use of -Response time will be extremely delayed at lower temperature than the operating
temperature range and on the other hand at higher temperature LCD's show dark color in
them.
