Note 4) After stabilizing and leaving the panel alone at a given temperature for 30 min , the measurement
should be executed. Measurement should be executed in a stable, windless, and dark room.
30 min after lighting the back-light. This should be measured in the center of screen.
Dual lamp current : 11.2mA (5.6mA x 2 ,Refer to the note(1) in the page 10 for further information.)
