White light tandem OLED display with filters
First Claim
1. A tandem OLED device having at least two spaced electrodes comprising:
- a) at least two broadband light-emitting units disposed between the electrodes that produce different emission spectra and each light-emitting unit produces light that has two or more spaced peak spectral components;
b) an intermediate connector disposed between each of the light-emitting units; and
c) an array of at least three different color filters associated with the device that receives light from the broadband light-emitting units, the band pass of each of the color filters being selected to produce different colored light, and wherein one or more individually addressable pixels is not filtered.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.

Abstract
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.
