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.

).
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 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.
