QUANTUM DOT BASED PIXEL ASSEMBLY

Abstract:

Display panel narrow band emission pixels and methods of fabrication are described. In an embodiment, such a pixel arrangement includes a pair of reflective electrodes, a pair of narrow band emission layers, and a pair of hole transport layers of different thickness over the pair of reflective electrodes and narrow band emission layers. A semi-transparent or transparent top electrode layer is located over the first and second hole transport layers.
