ABSTRACT:
An electronic device includes a substrate having a primary surface, an array lying along the primary surface, wherein the array includes one or more radiation-emitting components, one or more radiation-responsive components, or any combination thereof, and a first edge connector. In a direction parallel to the primary surface, the first edge connector lies between the array and a perimeter of the substrate. In one embodiment, the electronic device is designed, such that during normal operation, the first edge connector has a temperature difference, due to current flow through the first edge connector, of no more than 10° C. In another embodiment, the array has an emission homogeneity of at least 75% over a lifetime of the electronic device. The electronic device can be operated with good emission intensity and have an extended electronic device lifetime compared to an electronic device having edge connectors that can cause local heating.
