Luminance(brightness) all pixes "White" at Vmax

Luminance(brightness) all pixes "dark " at Vmax

Vmax is defined in Fig.9.

Note 3) The response characteristics of photo-detector output are measured as shown in Fig.10, 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.8.
