1.0 Handling Precautions
1) Since front polarizer iseasilydamaged, payattentionnot toscratchit.
2) Besure to turn off power supplywheninsertingor disconnectingfrom input connector.
3) Wipe offwater dropimmediately.Long contactwith watermaycause discoloration or spots.
4) When the panelsurface issoiled, wipeit withabsorbentcotton or othersoft cloth.
5) Since the panel ismade ofglass,it maybreakor crackifdroppedorbumped onhardsurface.
6) SinceCMOSLSI isusedin thismodule, takecareofstaticelectricityand insure human earth when
handling.
7) Donot open normodifythe Module Assembly.
8) Donot pressorpat the panel surfacebyfingers,handortooling.
9) Donot pressthe reflector sheetatthebackofthemoduleto anydirections.
10)Incase if amodule has tobeputbackintothepacking containerslotafter onceit was takenout fromthe
container, donotpress thecenteroftheCCFL reflector edge.Instead, press at the far endsoftheCCFL
reflector edge softly.Otherwise theTFT module maybe damaged.
11)Atthe insertionor removaloftheSignal InterfaceConnector,besurenot to rotatenortilttheInterface
Connector ofthe TFT module.
12)After installationofthe TFTmodule into anenclosure (DesktopmonitorBezel, forexample),donottwist
nor bend theTFTModuleevenmomentary.Atdesigning theenclosure, it shouldbetakeninto
consideration that nobending/twistingforcesare appliedtotheTFT modulefromoutside.Otherwisethe
TFTmodule maybe damaged.
