Notes 5) Definition of Luminance of White : measure the luminance of white at center point.

Notes 6)Definition of 5 points brightness uniformity (Measuring points: Refer to the Note 5)

Bmax

UNI

= ⎯⎯⎯⎯⎯⎯⎯

Bmin

Bmax: Maximum brightness

Bmin: Minimum brightness

Notes 7) Definition of Flicker level

Flicker Voltage

F = ⎯⎯⎯⎯⎯⎯⎯⎯⎯ x 100 %

LMD Voltage

♦ One maximum value of three estimated values.

♦ For this test ,an LMD(Light Measurement Device)is needed with adequate response time to track any

visible rate flicker component and with a voltage level output proportional

To luminance intensity.

♦ Test Pattern: For dot inversion Driving(Gray levels of foreground dots on the test panel

Are G22,G32,and G45)

♦ Test Point :Center point of the display area

1 2 ... 9 10 11 12 13 14 15 16 17 18 19 ... 81 82
