10. Precautions for Use of LCD Modules
10.1 Handling Precautions
(1) The display panel is made of glass. Do not subject it to mechanical shock by dropping it, etc.
(2) If the display panel is damaged and the liquid crystal fluid inside it leaks out be sure not to get any in your
mouth. If the fluid comes into contact with your skin or clothes promptly wash it off using soap and water.
(3) Do not apply excessive force to the display surface or the bezel since this may cause the color tone to vary.
(4) The polarizer covering the display surface of the LCD module is soft and easily scratched. Handle the
polarizer carefully.
(5) If the display surface is contaminated, breathe on the surface and gently wipe it with a soft dry cloth. If it is
still not completely clear use a moist cloth with one of the following solvents:
－ Isopropyl alcohol
－ Ethyl alcohol
Solvents other than those mentioned above may damage the polarizer. Specifically, do not use the
following:
－ Water
－ Ketone
－ Aromatic solvents
(6) Do not disassemble the LCD Module.
(7) If powered off, do not apply the input signals.
(8) To prevent destruction of the module by static electricity, be careful to maintain an optimum work
environment.
(9) Be sure to ground your body when handling the LCD Modules.
(10) Tools used for assembly, must be properly grounded.
(11) To reduce the amount of static electricity generated, do not conduct assembly or other work under very low
humidity conditions.
(12) The LCD Module is covered with a film to protect the display surface, remove film slowly under the ionizer.
10.2 Storage precautions
(1) When storing the LCD modules avoid exposure to direct sunlight or to the light of fluorescent lamps.
(2) The LCD modules should be stored within the rated storage temperature range. The recommend condition
is: Temperature: 0 ~ 35 ℃ at normal humidity.
(3) The LCD modules should be stored in a room without acid, alkali or other harmful gas.
10.3 Transportation Precautions
The LCD modules should not be dropped or subject to violent mechanical shock during transportation. Also
they should avoid excessive pressure, water, high humidity and direct sunlight.
10.4 Screen saver Precautions
Not display the fixed pattern for a long time. Use a screen saver, if the fixed pattern is displayed on the screen
10.5 Safety Precautions
(1) When you waste damaged or unnecessary LCDs, it is recommended to crush LCDs into pieces and wash
them off with solvents such as acetone and ethanol, which should later be burned
(2) Be sure to turn off the power supply when inserting or disconnecting the LED backlight cable.
(3) LED driver should be designed to limit or stop its function when over current is detected on the LED.
