Note.1: After stabilizing and leaving the panel alone at a given temperature for 30 minutes, the measurement should be executed. Measurement should be executed in a stable, windless, and dark room. Optical specifications are measured by Topcon BM-7(fast) with a viewing angle of 1 at a distance of 50cm and normal direction.

NO. 1 2 3 4 5 6 Item High Temperature Operating Low Temperature Operating High Humidity High Temperature Storage Low Temperature Storage Thermal shock Condition 70, 48Hrs -20, 48Hrs 50, 90%RH, 48Hrs 80, 48Hrs -30, 48Hrs No defect in cosmetic and operational function allowable. Total current Consumption should be below double of initial value. Criterion
-20, 30min~70, 30min, 10 cycles. Note: 1) Above conditions are suitable for our company standard products. 2) For restrict products, the test conditions listed as above must be revised.
9. Precautions for Use
9.1 Safety
(1) Do not 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.
9.2 Storage Conditions
(1) Store the panel or module in a dark place where the temperature is 235C and the humidity is below 5020%RH. (2) Store in anti-static electricity container. (3) Store in clean environment, free from dust, active gas, and solvent. www..com (4) Do not place the module near organics solvents or corrosive gases. (5) Do not crush, shake, or jolt the module.
9.3 Handling Precautions
(1) (2) (3) (4) (5) Avoid static electricity which can damage the CMOS LSI. The polarizing plate of the display is very fragile. So, please handle it very carefully. Do not give external shock. Do not apply excessive force on the surface. Do 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.
9.4 Warranty
The period is within twelve months since the date of shipping out under normal using and storage conditions.
