15 REV:A PAGE:5/22 2Precautions Please pay attentions to the followings as using the LCD module Handling (a) Do not apply strong mechanical stress like drop, shock or any force to LCD module It may cause improper operation, even damage (b) Because the polarizer is very fragile and easy to be damaged, do not hit, press or rub the display surface with hard materials (c) Do not put heavy or hard material on the display surface, and do not stack LCD modules (d) If the display surface is dirty, please wipe the surface softly with cotton swab or clean cloth (e) Avoid using Ketone type materials (eg Acetone), Toluene, Ethyl acid or Methyl chloride to clean the display surface It might damage the touch panel surface permanently The recommended solvents are water and Isopropyl alcohol (f) Wipe off water droplets or oil immediately (g) Protect the LCD module from ESD It will damage the LSI and the electronic circuit (h) Do not touch the output pins directly with bare hands (i) Do not disassemble the LCD module (j) Do not lift the FPC of Touch Panel Storage (a) Do not leave the LCD modules in high temperature, especially in high humidity for a long time (b) Do not expose the LCD modules to sunlight directly (c) The liquid crystal is deteriorated by ultraviolet Do not leave it in strong ultraviolet ray for a long time (d) Avoid condensation of water It may cause improper operation (e) Please stack only up to the number stated on carton box for storage and transportation Excessive weight will cause deformation and damage of carton box

16 REV:A PAGE:6/22 Operation (a) When mounting or dismounting the LCD modules, turn the power off (b) Protect the LCD modules from electric shock (c) The Driver IC control algorithms stated above should always obeyed to avoid damaging the LSI and electronic circuit (d) Be careful to avoid mixing up the polarity of power supply for backlight (e) Absolute maximum rating specified above has to be always kept in any case Exceeding it may cause non-recoverable damage of electronic components or, nevertheless, burning (f) When a static image is displayed for a long time, remnant image is likely to occur (g) Be sure to avoid bending the FPC to an acute shape, it might break FPC (h) Most of the touch screens have air vent to equalize the inside air pressure to the outside one The air vent must be open and liquid contact must be avoided as the liquid may be absorbed if the liquid is accumulated near the air vent (i) For the fragility of ITO film, it should avoid to use too tapering pen as the input material Touch Panel Mounting Notes (a) If a cushion is used between bezel/housing and film must be choose as free as enough to absorb the expansion and contraction to avoid the distortion of film (b) The cushion must be placed out of the Viewing Area (c) Bezel/Housing edge must be posited between Key Area and Viewing Area The edge enters the Key Area may cause unexpected input if the gap is too narrow or foreign particles like dusts exist between Bezel/Housing and ITO film (d) Mounting example:

17 REV:A PAGE:7/22 Bezel / Housing 2 ~ 5mm (Recommend) ITO Film Cushion ITO Glass TP Active Area TP Viewing Area 5 mm The corner part has conductivity Do not touch any metal part after mounting Others a) If the liquid crystal leaks from the panel, it should be kept away from the eyes or mouth b) For the fragility of polarizer, it is recommended to attach a transparent protective plate over the display surface c) It is recommended to peel off the protection film on the polarizer slowly so that the electrostatic charge can be minimized
