Note 5) After stabilizing and leaving the panel alone at a given temperature for 30 minutes, the measurement
should be executed. Measurement should be executed in a stable, windless,and dark room. 30 minutes after lighting the back-light. This should be measured in the center of screen. Lamp current : 6.0 mA Environment condition : Ta = 25 r 2 qڞٻ
