Patent 11777061 was granted and assigned to Lumileds on October, 2023 by the United States Patent and Trademark Office.
Described at light emitting diode (LED) devices emitting different colors on the same wafer, which facilitates their integration with close packing density (not requiring transfer of devices from two different wafers to a third substrate module). The LED devices and driving methods allow light of different colors and similar luminance levels to be emitted for given input current.
