摘要:
A light-emitting array includes a semiconductor LED structure, multiple transparent dielectric bodies, a set of multiple, independent first electrical contacts, and a set of second electrical contacts. The LED structure extends contiguously over the array. The second electrical contacts are in electrical contact with the second semiconductor layer. Each dielectric body protrudes away from the first semiconductor layer and has on its surface an electrically conductive layer in electrical contact with the first semiconductor layer, forming a portion of a corresponding one of the first electrical contacts. Each dielectric body and corresponding first electrical contact define a corresponding discrete, circumscribed pixel region within the contiguous area of the array, each pixel region separate from the others. Some light emitted in the pixel region propagates into the dielectric body, undergoes internal reflection(s) within the dielectric body, and propagates out of the array through the dielectric body and diode structure.
