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 : 8.0mA (Refer to the note(1) in the page 13 for more information.)
