  • Publication number: 20240266383
    Abstract: Lighting-emitting devices and more particularly light-emitting diode (LED) chips with multiple wavelength emissions and related methods are disclosed. LED chips include separately formed active LED structures that are bonded together to form a single LED chip capable of emitting multiple wavelengths. Each active LED structure may be separately patterned into a number of individual light-emitting junctions such that after bonding, a single LED chip includes multiple light-emitting junctions from multiple active LED structures. Patterns of individual light-emitting junctions may be selected so that when bonded together, emissions from different active LED structures may pass through LED chips with reduced interactions with one another. Certain aspects include vertical and horizontal offset positions for light-emitting junctions formed from different active LED structures.

  • Publication number: 20240266462
    Abstract: Solid-state lighting devices, and more particularly to laser etching light-emitting diode (LED) devices and related methods are disclosed. LED devices that use sapphire substrates are difficult to etch using conventional techniques, but laser etching and ablation of sapphire substrates overcomes these challenges. Laser etching a surface of the sapphire substrate can form light-extraction features that include structures formed in or on light-emitting surfaces of substrates. Light-extraction features may include repeating patterns of features with dimensions that, along with reduced substrate thicknesses, provide targeted emission profiles for flip-chip structures, such as Lambertian emission profiles. In some embodiments, laser ablation of the sapphire substrate can also be used to form trenches between active layer portions of an LED matrix to form pixels that reduce interference between the active layer portions.

  • Patent number: 11423422
    Abstract: The present disclosure relates to performing attribution modeling in real time using user-specified segments of touchpoint data retrieved from a database using a user-specified attribution model. For example, in one or more embodiments, a system stores raw touchpoint data in a database comprising an aggregator and a plurality of nodes. In particular, each node stores touchpoint data associated with a different user. Upon receiving a first query, the system can, in real time, generate and provide a first digital attribution report based on the stored touchpoint data. Upon receiving a second query, the system can generate a second digital attribution report for a user-specified segment of the touchpoint data represented in the first digital attribution report. Specifically, the system retrieves touchpoint data associated with the user-specified segment from the nodes of the database and uses the aggregator to combine the data to generate the second digital attribution report.
