  • Publication number: 20240234642
    Abstract: Solid-state lighting devices, and more particularly sidewall arrangements for light-emitting devices such as light-emitting diodes (LEDs) are disclosed. LED devices may include light-altering materials that are provided around peripheral sidewalls of LED chips without the need for a supporting submount or lead frame. The side layer around the peripheral sidewall of the LED chip can include an inner layer and an outer layer, each with different light altering properties. For example, the inner layer can be reflective so as to improve the light output and/or efficiency of the LED chip, while the outer layer can be absorptive so as to avoid interaction and/or crosstalk with neighboring LED chips. By having a reflective inner layer, and an absorptive outer layer, light output, sharpness, and contrast can be improved.

  • Patent number: 11817526
    Abstract: A pixelated-LED chip includes an active layer with active layer portions, segregated by streets, that are configured to illuminate different light-transmissive substrate portions to form pixels. A light extraction surface of each substrate portion includes protruding features and light extraction surface recesses that may be formed by sawing. Underfill material may be provided between a pixelated-LED chip and a mounting surface, as well as between pixels and between anodes and cathodes thereof. Certain implementations provide light extraction surface recesses that are non-parallel to each street defined through the active layer. Certain implementations provide light extraction surface recesses that are non-aligned with (e.g., non-parallel to) anode-cathode boundaries of each anode-cathode pair. Such arrangements reduce a likelihood of cracking in portions of a pixelated-LED chip. Methods for fabricating pixelated-LED chips are also provided.
