Intel patent outlines embedding MicroLEDs directly into CPU package to light up wording or work as an 'extra aesthetic component'

Intel has published a patent to integrate MicroLEDs directly into a CPU package. Aside from communication functions, Intel lists many possible uses, including using multi-colored lights to light up the wording on a processor. The patent, filed in 2022 but only published earlier this month, describes embedding a MicroLED into the package by using a glass substrate and through-glass vias (TGV), connecting directly to a die for power and signal routing. The patent says the purpose of the LEDs is "either aesthetic components of the electronic device or to indicate certain operations being performed by the electronic device."

As is the case with any patents, the purpose of embedding MicroLEDs into a chip is left open-ended. However, Intel interestingly calls out implementing MicroLEDs into a CPU, specifically, and provides several examples of how the tech might be used. …
