Notes:
1. No dew condensation to be observed.
2. The function test shall be conducted after 4 hours storage at the normal temperature and humidity after removed from the test chamber.
3. Vibration test will be conducted to the product itself without putting I in a container.

Notes:
1. The definition of dot: The size of a defective dot over 1/2 of whole dot is regarded
as one defective dot.
2. Bright dot: Dots appear bright and unchanged in size in which LCD panel is
displaying under black pattern.
