Recovery time should be 24 hours minimum. Moreover, functions, performance and
appearance shall be free from remarkable deterioration within 50,000 hours under ordinary
operating and storage conditions room temperature (20+8°C), normal humidity (below 65%
RH), and in the area not exposed to direct sun light.
11-4. Precaution for using LCM 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 isoproply alcohol, ethyl alcohol or trichl or otrifl or othane, do not use water, ketone or aromatics and never scrub hard.
3. Do not tamper in any way with the tabs on the metal frame. 4. Do not made any modification on the PCB without consulting YB. 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.
YEEBO LCD Limited LCD,LCM Specialist

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. 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. Operation Precautions:
1. Keep the temperature within the specified range usage and storage. Excessive temperature and humidity could cause polarization degradation, polarizer peel-off or generate bubbles.
2. For long-term storage over 40°C is required, the relative humidity should be kept below 60%. Avoid direct sunlight.
Limited Warranty
YB LCDs and modules are not consumer products, but may be incorporated by YB’s customers into consumer products or components thereof, YB does not warrant that its LCDs and components are fit for any such particular purpose. 1. The liability of YB is limited to repair or replacement on the terms set forth below. YB
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 betweenYB and the customer, YB will only replace or repair any of its

LCD which is found defective electrically or visually when inspected in accordance with YB 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. 12.DESCRIBE TO THE PART NO:
