Note 1) Test Equipment Setup
The measurement should be executed in a stable, windless and dark room between
30min and 40min after lighting the back-light at the given temperature for stabilization
of the back-light. This should be measured in the center of screen.
Single lamp current : 6.5mA (Refer to the note(1) in the page 12 for more information.)
Environment condition : Ta = 25 ± 2 ° C
