IntelliPix enables smaller and lighter AR spectacles by coupling a video pipeline with an integrated digital backplane and driver for pixels as small as 2.5µm in a single-chip.

The companies intend to develop  a software-defined and scalable feature set for the microdisplays.

IntelliPix supports up to 100 times faster modulation while consuming 4 to 12 times less system power across the video pipeline, compared to CP’s previous platforms, while unlocking the potential for amplitude liquid crystal on silicon (LCoS), emerging microLED and future phase-based holographic systems.


By intelligently focusing only on changing pixels, IntelliPix is directed to pixels that are active, while conserving power in inactive pixel regions, resulting in high image quality and brightness, while significantly lowering the overall display subsystem power (OnDemand Pixel).

By leveraging the high-performance, ultra-low power, and broad feature integration capability of GF’s 22FDX platform, CP is able to deliver IntelliPix’s smart pixel digital backplane integrated with its proprietary real-time video pipeline at high frame rates and low latency all in one single chip with no compromises in display area, cost or power consumption to meet the critical requirements for widespread consumer AR.

For emerging microLED pixel technology, IntelliPix-iDrive can be configured with a constant current pixel drive optimized to deliver pixel to pixel uniformity supported with a software-defined drive scheme and a MIPI interface.

IntelliPix also provides an IntelliPix-vDrive™ configuration as a voltage/charge driven pixel optimized for driving LC based pixels for both amplitude and phase/holographic light modulation.

The OneChip physical design of IntelliPix eliminates traditional distinctions between display pixel drive (backplane) and display driver IC (DDIC) functions to reduce the overall physical volume and power consumption while enabling cutting-edge features. The partnership between CP and GF enables a customized Intellipix architecture based on a vDrive or iDrive modulated backplane/display configured to customer specifications.

The IntelliPix microdisplay technology platform is customizable for resolutions up to 2048 x 2048 and beyond. Expect the first commercial products featuring CP’s IntelliPix to be on the market in 2023.
