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
