(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. 12.2Srorang Conditions (4)Store the panel or module in a dark place where the temperature is 23±5 and the humidity is below 45 ±20%RH. (5)Store in anti-static electricity container. (6)Store in clean environment, free from dust, active gas, and solvent. Page 18 of 19 Rev. A00 Oct 2010

19 (7)Do not place the module near organics solvents or corrosive gases. (8) )Do not crush, shake, or jolt the module. 12.3Handling Precautions (9)Avoid static electricity, which can damage the CMOS LSI. (10)The polarizing plate of the display is very fragile, please handle if very carefully. (11)Do not give external shock. (12)DO mot apply excessive force on the surface. (13)Bo not wipe the polarizing plate with a dry cloth, as it may easily scratch the surface of plate. (14)Do not use ketonics solvent & Aromatic solvent, use with a soft cloth soaked with a cleaning naphtha solvent. (15)Do not operate it above the absolute maximum rating. (16)Do not remove the panel or frame from the module. 12.4Warranty The period is within twelve months since the date of shipping out under normal using and storage conditions. 13.Factory FACTORY NAME: FACTORY ADDRESS: FACTORY PHONE: 14.Revision history Version Revise record Date v0.0 Original version Page 19 of 19 Rev.
