Organic electroluminescent multicolor image display device

摘要

An organic electroluminescent multicolor image display device is disclosed containing an image display array made up of a plurality of light emitting pixels arranged in intersecting files (rows and columns). Each pixel contains a light transmissive first electrode, an electroluminescent medium overlying the first electrode, and an overlying second electrode. The electrodes connect the pixels in an X-Y addressing pattern. The organic electroluminescent medium emits in the blue region of the spectrum. Each pixel is divided into at least two sub-pixels. The electrodes of one set of parallel files is divided into at least two laterally spaced elements each of which joins and forms a part of one sub-pixel of each pixel in the same file. A fluorescent medium capable of absorbing light emitted by the electroluminescent medium and emitting at a longer wavelength is positioned to receive emitted light from the first electrode means. The fluorescent medium is confined to only one of the sub-pixels of each pixel.
