Abstract: At least one array of LEDs (e.g., in a flip chip configuration) is supported by a substrate having a light extraction surface overlaid with at least one lumiphoric material. Light segregation elements registered with gaps between LEDs are configured to reduce interaction between emissions of different LEDs and/or lumiphoric material regions to reduce scattering and/or optical crosstalk, thereby preserving pixel-like resolution of the resulting emissions. Light segregation elements may be formed by mechanical sawing or etching to define grooves or recesses in a substrate, and filling the grooves or recesses with light-reflective or light-absorptive material. Light segregation elements external to a substrate may be defined by photolithographic patterning and etching of a sacrificial material, and/or by 3D printing.

Abstract: Pixelated-LED chips and related methods are disclosed. A pixelated-LED chip includes an active layer with independently electrically accessible active layer portions arranged on or over a light-transmissive substrate. The active layer portions are configured to illuminate different light-transmissive substrate portions to form pixels. Various enhancements may beneficially provide increased contrast (i.e., reduced cross-talk between pixels) and/or promote inter-pixel illumination homogeneity, without unduly restricting light utilization efficiency. In some aspects, a light extraction surface of each substrate portion includes protruding features and light extraction surface recesses. Lateral borders between different pixels are aligned with selected light extraction surface recesses. In some aspects, selected light extraction surface recesses extend through an entire thickness of the substrate. Other technical benefits may additionally or alternatively be achieved.

The light-altering material may be arranged on a lumiphoric material adjacent to the LED chip in various configurations. The LED package may include an encapsulant on the light-altering material and the lumiphoric material.
