title = "Pulsed illumination driver with intensity control and RGB mixing capabilities for high-resolution near to eye display",
abstract = "The recently reported {"}Angular Spatial Light Modulator{"}(ASLM) light engine, using pulsed illumination synchronized to a Digital Micromirror Device (DMD), shows significant promise to enhance pixel counts of Near-To-Eye Displays (NED) without increasing package volume, but requires an uncommon illumination driver. We present a field effect transistor based constant-current driver that is fast, compact, and scalable to RGB illumination. The digital-To-Analog convertor modulates intensity on-The-fly for illumination-based multiplexing. The driver outputs 100 ns pulses, up to 24 kHz repetition rate. The circuit is demonstrated for two laser diodes and for two LEDs in an ASLM-enhanced pixel count display.",
