Liquid Crystal Display
Product Specification
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.
