4. Optical Specification

Optical characteristics are determined after the unit has been ‘ON’ and stable for approximately 30 minutes in

a dark environment at 25±2°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 °.

FIG. 1 presents additional information concerning the measurement equipment and method.
