    6. Optical Specification Optical characteristics are determined after the unit has been ‘ON’ and stable for approximately 45 minutes in a dark environment at 25°C. The values specified are at an approximate distance 500 mm from the LCD surface at a viewing angle of φ and Ө equal to 0°.. Fig.1 presents additional information concerning the measurement equipment and method.
