Handling LCD panel

Handling LCD panel
(when replacing panel or backlight lamp)
1. Do not apply any strong mechanical shock to the LCD panel
Since this LCD panel is made of glass, excessive shock may damage the panel or cause a
malfunction.
2. Do not press hard on the LCD panel surface.
In the LCD panel, the gap between two glass plates is kept perfectly even to maintain display
properties and reliability. Any hard pressure on the LCD panel may cause the following problems:
- Ununiformity of color
- Disorder of orientation of liquid crystal
Problem returns to normal condition after a while or by turning power off and on again.
However these operations should be avoided to insure reliability.
3. Do not scratch the polarizing film on the LCD panel surface.
- Do not press or rub the display surface with a hard tool, tweezers, etc.
- For handling, use cotton or conductive gloves so that the display surface is not soiled.

Cleaning LCD panel

If dust or dirt soils the display surface, clean it as follows with a soft dry cloth without chemicals.
Dust - Wipe off with a soft cloth. (do not rub.)
Dirt - Apply clear water to a soft cloth and squeeze hard out of water drops, then lightly wipe off the
specified parts. Only if the dirt is hardly wiped off, use isopropyl alcohol or ethanol. Be careful not to
splash the water or the solvents on the edge of polarizer and in the LCD unit. The polarizer possibly
exfoliates due to the solvent and water penetrated between the polarizer and the LCD panel.
Caution !
* Do not use unspecified solvent such as ketone (acetone, etc.) and aromatics (xylene, toluene, etc)
* Be careful not to allow the water of solvent to enter the module.
* If solvent or water drops are left for a long period of time, the part may become deformed or
discolored.
* Wipe off immediately in the same way as for dirt.
* Do not allow oil to adhere to the module since excessive oil is hard to clean.
