Note 5) 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 backlight. This should be measured in the center of screen. Lamp current : 6.0 mA (Inverter : SI1700) Environment condition : Ta = 25 r 2 qC
