Inspection standards

AQL(Acceptable Quality Level

AQL of major and minor defect.

Basic conditions for inspection
The LCM face to us, in normal environment, the lux is 1000±200.(Darkroom’s lux: 100±50),About an angle of incidence 30,a distance of 30 cm with an angle of 45 degree to check the products without uncovering the film!

Precautions for using LCD modules

Safety

1. Do mot swallow any liquid crystal ,even if there is no proof that liquid crystal is poisonous.
2. If the LCD panel breaks, be careful not to get liquid crystal to touch your skin.
3. If skin is exposed to liquid crystal, wash the area thoroughly with alcohol or soap.

Srorang Conditions

1. Store the panel or module in a dark place where the temperature is 23±5℃and the humidity is below 45 ±20%RH.
2. Store in anti-static electricity container.
3. Store in clean environment, free from dust, active gas, and solvent.
4. Do not place the module near organics solvents or corrosive gases.
5. Do not crush, shake, or jolt the module.

Handling Precautions

1. Avoid static electricity, which can damage the CMOS LSI.
2. The polarizing plate of the display is very fragile, please handle if very carefully.
3. Do not give external shock.
4. DO mot apply excessive force on the surface.
5. Bo not wipe the polarizing plate with a dry cloth, as it may easily scratch the surface of plate.
6. Do not use ketonics solvent & Aromatic solvent, use with a soft cloth soaked with a cleaning naphtha solvent.
7. Do not operate it above the absolute maximum rating.
8. Do not remove the panel or frame from the module.

Warranty
The period is within twelve months since the date of shipping out under normal using and storage conditions.
