◆ Method of Brightness Measurement
（１） Measuring Device
TOPCON BM-7,Measuring Field:1°
（２） Measuring Point
Center of Display θ=0°, φ=0°
On condition θ: A vertical angle from measuring direction to perpendicular.
φ: A horizontal angle from measuring direction to perpendicular.
LCD Module
Distance :500mm
Center
(Pixel)
(X, Y)= (320, 240）
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 toθ=0°, φ=0°.
・ Change signal voltage to measure maximum brightness Y1 and minimum brightness
Y2.
・ Contrast is derived from CR=Y1/Y2.
