Note 1) Test Equipment Setup

After stabilizing and leaving the panel alone at a given temperature for 60 min , the

measurement should be executed. Measurement should be executed in a stable, windless, and

dark room. 60 min after lighting the back-light. This should be measured in the center of

screen.
