“At its core, CP departs from the traditional full bandwidth, raster-based pipeline dating back to the birth of NTSC toward a data flow optimized for real-time AR applications. Given AR imagery, in general, does not fill the entire field of view, only transmitting active pixel data results in the ability to drastically increase performance for those active pixels while reducing overall display sub-system power. “We have again revolutionized the drive architecture to manage images intelligently at the pixel level” stated Edmund Passon, Co-CEO and CTO of Compound Photonics. “IntelliPix™ also integrates its real time video pipeline and programmable drive scheme with adjustable constant current iDrive or voltage driven (vDrive) options into a single chip solution. The overall technology advancement in IntelliPix™ enables up to 100x faster modulation while consuming 4x to 12x less system power across the video pipeline vs. CP’s previous platforms while unlocking the real potential for microLED and future phase –based holographic systems.”
Legacy video pipelines transport full frames/bandwidth to the display subsystem where every transition moves electrons reducing battery life. OnDemand Pixels™, the key component of IntelliPix™, optimizes the drive of pixels based on both content and use environment. This proprietary feature provides significant power saving as the system modulates video parameters across the field of view, dependent on user activity. This active pixel-based approach also enables for the bursts of increased performance by making more bandwidth and higher refresh rates available for demanding content regions. Additionally, when combined with eye tracking, OnDemand Pixels™ opens the door to foveated rendering with attendant benefits for optimized processing on the SoC/AP.
IntelliPix™’s 100x modulation speed increase takes full advantage of the faster response time of microLEDs, which can be applied to higher bit depth, refresh rates, or the ability to add multiple focal planes. For phase-based holographic systems, the 100x increase enables complex waveforms providing near zero ripple. The platform also retains all key features of CP’s current NOVA display drive architecture to achieve low latency and on the fly frame by frame control to avoid image lag.
