Full-color passive-matrix 5.7 in, diagonal quarter video graphic array (320
x 240 pixels) organic electroluminescence displays with a passive-matrix d
rive have been proven to be practical for commercial purposes. The display
panels have an anti-reflection filter with a transmittance of 70%. The maxi
mum brightness of the panels was up to 140 cd/m(2) because of the use of th
e dual-scan driving method, improvement of the device characteristics, and
pixels having an effective aperture ratio of about 70%. (C) 2001 Elsevier S
