Abstract
Integrated active-matrix light emitting pixel arrays based displays are provided. An example integrated device includes a backplane including pixel circuits conductively coupled to an array of light-emitting elements through intermediate conductive layers to form an array of active-matrix light-emitting pixels and a transparent conductive layer on the array of the light-emitting elements. Each of the light-emitting elements includes one or more quantum well semiconductor layers between a first contact electrode and a second contact electrode, and the first contact electrodes of the light-emitting elements is respectively bonded and conductively coupled to the pixel circuits in the backplane via the respective intermediate conductive layers. The transparent conductive layer is in contact with the second contact electrodes of the light-emitting elements to form a common electrode of the light-emitting elements, and a top surface of each of the second contact electrodes is fully in contact with the transparent conductive layer.
