Abstract: A sub-pixel array device includes a plurality of optoelectronic devices disposed on a substrate, the plurality of optoelectronic devices including a light-emitting device and a light-converting device, and a bank structure that separates adjacent optoelectronic devices. Each optoelectronic device includes a first electrode, a second electrode, an active layer disposed between the electrodes and including a solution processable semiconductor, and a photo-crosslinkable material disposed between the first electrode and the second electrode. The photo-crosslinkable material may be incorporated within the active layer of each of the plurality of optoelectronic devices, so as to form a light-emitting device having a photo-crosslinkable emissive layer and a light-converting device having a photo-crosslinkable photo-active layer. The photo-crosslinkable material may be disposed between the active layer and the second electrode, such as incorporated within a capping layer or a charge transport layer disposed between the active layer and the second electrode.

Abstract: A quantum dot light-emitting apparatus includes a substrate, with a first electrode layer located on the substrate. An emissive layer having a first set of quantum dots is electrically coupled with the first electrode layer, and a second electrode layer is also electrically coupled with the emissive layer. The second electrode layer is located opposite the first electrode layer, relative to the emissive layer. A first charge transport layer is placed between the emissive layer and the first electrode layer, and a second charge transport layer is placed between the emissive layer and the second electrode layer. At least one of the first charge transport layer and the second charge transport layer includes a second set of quantum dots.
