Abstract: A device may include a metal contact between a first isolation region and a second isolation region on a first surface of an epitaxial layer. The device may include a first sidewall and a second sidewall on a second surface of the epitaxial layer distal to the first isolation region and the second isolation region. The device may include a wavelength converting layer on the epitaxial layer between the first sidewall and the second sidewall.

Abstract: A light-emitting device is disclosed which includes a segmented active layer disposed between a segmented conductivity layer and a continuous conductivity layer, the active layer, the segmented conductivity layer, and the continuous conductivity layer being arranged to define a plurality of pixels, each pixel including a different segment of the segmented conductivity layer and the segmented active layer. A continuous wavelength converting layer disposed on the continuous conductivity layer is provided. A plurality of first contacts, each first contact being electrically connected to a different segment of the segmented conductivity layer is provided. One or more second contacts that are electrically connected to the continuous conductivity layer are also provided, the number of second contacts being less than the number of first contacts.
