Abstract:
An inventive light-emitting apparatus comprises an array of multiple light-emitting pixels, and one or more transmissive optical elements positioned at a light-emitting surface of the light-emitting pixel array. One or more of the light-emitting pixels is defective. Each optical element is positioned at a location of a corresponding defective light-emitting pixel, and extends over that defective pixel and laterally at least partly over one or more adjacent pixels. Each optical element transmits laterally at least a portion of light emitted by the adjacent pixels to propagate away from the array from the location of the defective pixel, reducing the appearance of the defective pixel.
