Note 1) Test Equipment Setup
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.
A single lamp current : 5.0mA
Environment condition : Ta = 25 ± 2 ° C
