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.
