4. Optical Specifications
Optical characteristics are determined after the unit has been ‘ON’ and stable for approximately 30
minutes in a dark environment at 25
°
C. The values specified are at an approximate distance 50cm from
the LCD surface at a viewing angle of
Φ
and
θ
equal to 0
°
C.
FIG 1. presents additional information concerning the measurement equipment and method.

Notes:
1. Contrast Ratio (CR) is defined mathematically as :
Surface Luminance with all white pixels
Contrast Ratio =
Surface Luminance with all black pixels
2. Surface luminance is the center point across the LCD surface 50cm from the surface with all
