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
