Note (1) Test Equipment Setup

The measurement should be executed in a stable, windless and dark room between

30min after lighting the back light at the given temperature for stabilization of the back light. This should be measured in the center of the screen.

LED forward current : If = (384mA) Environment condition : Ta = 25 ± 2 °C
