Fig.4 Definition of Viewing Angle
Note 1) The viewing angle range is defined as shown Fig.4.
Note 2) Contrast ratio is defined as follows:
Co
Luminance(brightness) all pixes "White" at Vmax
Luminance(brightness) all pixes "dark " at Vmax
=
Vmax is defined in Fig.6.
Note 3) The response characteristics of photo-detector output are measured as shown in Fig.7, assuming
that input signals are applied so as to select and deselect the dot to be measured, in the optical
characteristics test method shown in Fig.5.
