Chandler, Arizona, USA, June 11th , 2020 – Compound Photonics US Corporation (CP), a leading provider of compact high-resolution microdisplay solutions for Augmented Reality (AR) and Mixed Reality (MR) applications, today, announced multiple customer validations of its NOVA display drive architecture, an innovative software-defined platform, currently implemented in both of CP’s microLED and LCoS display technology solutions, that optimizes the video data pipeline for real-time AR/MR in near-eye mobile display applications.
Edmund Passon, CP Co-CEO commented, “CP has long recognized that battery weight and form factor along with real-time compensation for head motion and other artifacts are key areas where the display subsystem greatly affects the user experience for AR glasses. We have carefully engineered all aspects of the display subsystem to deliver a highly engaging visual experience for the full range of consumer and industrial AR/MR devices and markets. The NOVA architecture, driving the world’s highest brightness and most efficient microLED and LCoS displays, provides system developers the tools needed to optimize within the trade-off space of power, speed and performance – via frame by frame control of drive electronics, illumination, and image quality.”
CP displays with NOVA have achieved the following key performance metrics for optimized AR:
- Latency of < 1 msec and video frame rates up to 240 Hz to allow for smooth video while mitigating image swimming & lag due to high angular velocity head motion
- Color Persistence <1 msec (color sub-frame rates up to 1440 Hz) to prevent image smearing/blurring & color break-up or “rainbow effect”
- Display subsystem power consumption as low as 120 mW for mixed AR and text-based content
NOVA leverages the MIPI interface as a transport layer but receives pixel data in a field sequential color format along with embedded display control commands. Its high performance logic achieves the fastest video pipeline currently available. Embedded control commands adjust parameters including frame rate, number of color sub-frames, bit depth, gamma, illumination intensity, and duty cycle on a frame by frame basis without visible image tearing while adjusting power according to complexity of video content and the specific use case. Additionally, custom operations to implement image distortion correction, image rotation, image shifting and other features can be combined with pixel data encoding by utilizing late stage rendering on the SoC/GPU host.
CP’s NOVA display drive architecture is available in CP’s previously announced high-performance constant current drive digital microLED backplane and already fully integrated into the 1080p and 2K x 2K LCoS displays packaged as integrated display modules (IDM) with a low-pin count direct MIPI input.
