Panels used in LCD and LED panel televisions are quite sensitive in electrical and
physical aspects. Therefore, the following warnings should be observed.
1. Panel surface is quite sensitive and can be damaged easily. Take care to avoid
scratches on the panel surface. When you need to lay down the panel, place it on a
floor, which will not cause damages. Besides, do not use rough materials when
touching or wiping the panel clean.
2. Keep panel surface clean. Put on rubber gloves when touching panel surface. To
clean the surface, use a mild cleaning agent that does not get electrified.
3. Keep LCD and LED module away from water. Spilling water in or on the panel
causes electrical damage. It should be wiped dry, if needed.
4. Avoid sudden temperature and humidity changes. Sudden changes of temperature
and humidity may harm the panel.
5. High temperature and humidity shortens product life. LCD and LED panels are not
suitable for use under high temperature and humidity conditions. The user should
observe the stated values of temperature and humidity.
6. Keep it away from harmful (corrosive) gases. Corrosive gases damage chemical
and electronic structure of LCD and LED panel.
7. Static electricity flow may damage the panel. LCD and LED module contain
materials sensitive to static electricity such as CMOS and etc. The body should be
grounded before touching the panel. Also, you must not touch connector areas with
bare hands.

same image on the screen for a long time may lead image retention and the panel
may get damaged. Therefore, TV should be turned off when not in use and the image
should be changed within certain intervals when displaying still images.
