A.1 Optical Characteristics
The optical characteristics are measured under stable conditions at 25°C (Room
Temperature)
1. Since the front polarizer is easily damaged, pay attention not to scratch it.
2. Be sure to turn off the power supply when inserting or disconnecting from the
input connector.
3. Wipe off water drops immediately. Long contact with water may cause discolor-
ation or spots.
4. When the panel surface is soiled, wipe it with absorbent cotton or other soft
cloth.
5. Since the panel is made of glass, it may break or crack if dropped or bumped on
hard surface.
