? Method of Brightness Measurement
( 1 ) Measuring Device
TOPCON BM-7?Measuring Field:1°
( 2 ) Measuring Point
Center of Display ? = 0 °? f = 0 °
On condition ? : A vertical angle from measuring direction to perpendicular.
f : A horizontal angle from measuring direction to perpendicular.
LCD Module
Distance : 5 0 0 m m
Center
(Pixel)
( X , Y ) =( 2 4 0 , 1 1 7 )
TOPCON BM-7
( 3 ) Method of Measuring
Apply signal voltage (displayed in white) to maximize brightness and measure brightness B (cd/m2 ).
The distance between BM-7’s front lens to surface panel is 500mm.
Measured after backlight has been lit for more than 30 minutes.
? Method of Contrast Measurement
( 1 ) Measuring Device
TOPCON BM-7?Measuring Field:1°
( 2 ) Measuring Point
Center of display: same as Method of Brightness Measurement
( 3 ) Method of Measuring
· Set LCD module to? = 0 °? f = 0 °.
· Change signal voltage to measure maximum brightness Y1 and minimum brightness Y2.
· Contrast is derived from CR=Y1/Y2.
