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°. The values specified are at
an approximate distance 50 cm from the LCD surface at a viewing angle of Φ and θ
equal to 0°. Appendix A presents additional information concerning the specified
characteristics.

Note 1: Contrast Ratio (CR) is defined mathematically as:
(Surface Brightness with all white pixels) /
(Surface Brightness with all black pixels)
Note 2: Surface brightness is the center of 5 points(this means number 3 in
Appendix A-1 Brightness) across the LCD surface 50 cm from the surface
with all pixels displaying white. For more information see Appendix. A.
