  • Patent number: 11961875
    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.
    Type: Grant

  • Publication number: 20230086869
    Abstract: This specification discloses LEDs and LED arrays configured such that an electric field may be applied during operation of the device to drive charge carriers (electrons or holes) away from perimeter semiconductor surfaces of the LEDs, thereby reducing non-radiative recombination near those perimeter surfaces. These LEDs and LED arrays comprise (e.g., metal) field plates, arranged around the perimeter surfaces of the LEDs, by which the electric field may be applied. In some variations, the bias voltage applied to the field plates to produce the electric fields may be separately controlled for some, or each, LED in an array. In other variations the bias applied to the field plates is the same for each LED in an array.

  • Patent number: 10957820
    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.
