4. Optical Specification
Optical characteristics are determined after the unit has been 'ON' for 30min in a dark environment at
The values specified are at an approximate distance 50cm from the LCD surface at a viewing angle of Φ and
θ equal to 0 °.
It is presented additional information concerning the measurement equipment and method in FIG. 1.
