Latest Patents

Daniel Herrera holds a patent for a groundbreaking invention titled "Driving for Multi-Junction Polychromic Display Devices." This patent describes a lighting system and method for driving an array within the lighting system. The array consists of vertically-stacked multi-color micro light-emitting diode (microLED) devices that emit light of different colors. The driving circuits and a ground switching circuit are controlled by processing circuitry to sequentially emit the colors of each microLED by independently driving pn junctions of the microLED. Each driving circuit includes multiplexers that receive a sink/source current and selectively provide the sink/source current to a channel based on control signals from the processing circuitry. Dimming of a particular color is achieved using a pulse width modulated (PWM) signal to adjust the duty cycle over which the sink/source current is applied to the channel. The ground switching circuit selects another channel using multiplexers and grounds the channel, ensuring that current flows through only one of the pn junctions at a time. Daniel holds 1 patent for this innovative technology.
