And since the module in so constructed as to be fixed by utilizing fitting holes in the printed circuit board. Extreme care should be needed when handling the LCD modules. 12.2 Caution of LCD handling and cleaning When cleaning the display surface, Use soft cloth with solvent [recommended below] and wipe lightly ●.
DEM 320240M TMH-PW-N Production Specification 12.6 Storage In the case of storing for a long period of time for instance, for years for the purpose or replacement use, the following ways are recommended. ●.Storing in an ambient temperature 10°C to 30°C, and in a relative humidity of 45% to 75%. Don’t expose to sunlight or fluorescent light. ●.Storing in a polyethylene bag with the opening sealed so as not to enter fresh air outside in it. And with no desiccant. ●.
