A tandem OLED device having spaced electrodes includes broadband
light-emitting units disposed between the electrodes that produce
different emission spectra and each light-emitting unit produces light
that has multiple spaced peak spectral components, and an intermediate
connector disposed between each of the light-emitting units. The device
also includes an array of at least three different color filters
associated with the device which receives light from the broadband
light-emitting units, the band pass of each of the color filters being
selected to produce different colored light, wherein the full width at
about half maximum of at least one of such spaced peak spectral
components produced by each emitting unit is within the band pass of a
color filter, and wherein each of the at least three different color
filters receives at least one spaced peak spectral component having a
full width at about half maximum that is within its band pass.
