2. Handling Precaution
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 and/or sharp tools on the surface of display area.
2.1.2. The polarizer placed on the display surface is easily scratched and damaged. Extreme
care should be taken when handling it. 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 to clear display surface, and never scrub it hard.
2.1.3. Keep LCD panels away from direct sunlight. The storage environment should be
dust-free, clean, dry, temperature is 25℃±10℃ and the humidity is below 55% RH.
2.1.4. Do not input any signal before power is turned on.
2.1.5. 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.
2.1.6. It’s important to control soldering temperature and time. RoHS compliant materials
might need higher temperature and time, but try to keep temperature under 350℃ and
time in 3-5 sec.
2.1.7. EL is manufactured from the organic film, and is easily affected by temperature,
humidity and other environmental impact. Long time storage might cause low quality of
the case. Therefore, please start production in 3 months after reception of the LCM. If in
any case, long time storage over 3 months is necessary, please keep EL in vacuum
package or at least in humidity < 35% RH, and temperature 25℃±10℃.
Note: 2.1.7. is applied to EL backlight only.
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(almost low RH) is inductive to static, a humidity of 50-60% RH is
recommended in assembly line.
2.3 Operation Precautions:
2.3.1. DC voltage applied on LCM causes electrochemical reactions, which will deteriorate the
display over time. 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. LCD driving voltage should be kept within specified range; excess voltage will shorten
display life, while less voltage may not turn on LCM.
2.3.3. LCM response time will be extremely delayed in low operating temperature(such as -20
℃) than in room operating temperature. Therefore, higher LCD driving voltage is required
in low operating temperature; On the other hand, in high operating temperature (such as
+70℃) LCD shows dark background color, therefore lower LCD driving voltage is required.
Be sure to use the specified LCD driving voltage in different operating temperature2.4 Safety:
2.4.1 If the LCD panel breaks, be careful not to get the liquid crystal to touch your skin.
If the liquid crystal touches your skin or clothes, please wash it off immediately by using
soap and water.
2.5 WARRANTY POLICY
Bolymin .Will provide one-year warranty for the products only if under specification
operating conditions.
If there are functional defects found during the period of warranty, the defective
products would be replaced on a one-to-one basis.
Bolymin would not be responsible for any direct/indirect liabilities consequential to
any parties.
2.6 MTBF
2.6.1 .By specific test condition, MTBF based on 30℃normal operation temperature is
50,000hours.
2.6.2 Test Condition:
2.6.2.1 Supply Voltage for LCM: Typical Vdd
2.6.2.2 CC (Constant Current) mode and typical current is applied for LED.
2.6.2.3 Run-Patterns: by Bolymin's test program that has defined patterns and cyclic
period.
2.6.2.4 Humidity: 60%RH
2.6.3 Test Criteria:
Attenuation of average brightness: ≦ 50%
Increasing of current consumption for LCM/Backlight: ≦ 20%
Display function at room temperature: Normal
Appearance: Normal
