Display requirements for AR glasses are driving micro displays to be smaller, lower power, and higher performance. With these improvements, AR display systems can enable longer battery life, small and lightweight products and compelling user experience. Technologies such as micro-LED (Light Emitting Diode), micro-OLED (Organic-LED), LCoS (Liquid Crystal on Silicon), Texas Instruments DLP® technology, and LBS (LASER Beam Scanning) are available today to be used in AR applications.
The next generation of DLP Pico chipsets (digital micromirror devices and DLP controllers) are optimized for low power and small size while building upon DLP technology’s industry leading performance and optical efficiency standards.
The new digital micromirror device (DMD) will enable improved contrast while reducing optical engine volume. The new DLP controller will include features that improve performance (display resolutions of up to 4K UHD, input video frame rates of up to 1kHz, faster DMD refresh rates, reduced display latency and support for variable refresh rates) and reduce power consumption (panel self-refresh, intermittent display standby and compressed video input modes).
The chipsets will also include AR-centric features such as dynamic color adjustment & display dimming (based on ambient conditions), dynamic input image resizing and smart motion interpolation (reducing input bandwidth) and content adaptive illumination control (reducing illumination power).
This paper intends to introduce the next generation of Texas Instruments DLP Pico technology, elaborate on the new capabilities included in these chipsets, and showcase how DLP technology, combined with the high efficiency optical design presented at Photonics West Opto 2023, is well positioned to enable low power AR displays.
