31 ACX704AKM notes on handling (1) static charge prevention be sure to take the following protective measures. tft-lcd panels are easily damaged by static charges. a) use non-chargeable gloves, or simply use bare hands. b) use an earth-band when handling. c) do not touch any electrodes of a panel. d) wear non-chargeable clothes and conductive shoes. e) install grounded conductive mats on the working floor and working table. f) keep panels away from any charged materials. g) use ionized air to discharge the panels. (2) protection from dust and dirt a) operate in a clean environment. b) do not touch the front light surface. the surface is easily scratched. c) use ionized air to blow dust off the panel. (3) others a) do not twist or bend the flexible pc board especially at the connecting region because the board is easily deformed. b) do not drop the module. c) do not twist or bend the module. d) keep the module away from heat sources. e) do not dampen the module with water or other solvents. f) avoid storage or use the module at high temperatures or high humidity, as this may result in damage.
