1. Pixelated-LED chips and chip array devices, and fabrication methods:

Andrews' patent describes a pixelated-LED chip design consisting of independently electrically accessible active layer portions arranged on or over a light-transmissive substrate. This configuration allows for the illumination of different substrate portions, thereby forming individual pixels. The invention also includes enhancements that promote increased contrast and inter-pixel illumination homogeneity without sacrificing light utilization efficiency. Additionally, the patent introduces the use of underfill materials with improved surface coverage to prevent cross-talk between adjacent pixels.

2. Pixelated-LED chips with inter-pixel underfill materials, and fabrication methods:

This patent builds upon Andrews' earlier work and presents a pixelated-LED chip design with independently electrically accessible active layer portions supported by discontinuous substrate portions, forming multiple pixels. The invention introduces underfill materials of varying composition between sidewalls of adjacent pixels, with each underfill material possessing different properties such as reflection, scattering, absorption, filtering, etch-resistance, and light refraction. The patent also details a fabrication method that involves defining streets through the active layer and substrate, thinning the substrate, and supplying underfill material into the streets.
