Compound Photonics Partners With GLOBALFOUNDRIES To Produce Its MicroLED Micro Display Backplanes
In 2020 Compound Photonics (CP) announced its high-performance IntelliPix MicroLED micro display backplane technology. CP's backplane supports resolutions up to 2048x2048 and a pixel pitch from 1.5 um and up.
The integration of the driver into the backplane lowers power consumption while providing optimum performance by:

In 2020 Compound Photonics (CP) announced its high-performance IntelliPix MicroLED micro display backplane technology. CP's backplane supports resolutions up to 2048x2048 and a pixel pitch from 1.5 um and up.
The integration of the driver into the backplane lowers power consumption while providing optimum performance by:
- Enabling high speed signals between the drive and the backplane, where a simple 1 bit/dumb pixel model can result in a huge bandwidth (~38Gbps for 1080p) and associated power consumption. The integrated backplane plus logic under the pixel reduces this bandwidth and associated power while increasing both the feature set and performance.
- Integrating the driver into the pixel allows for increased logic and storing of pixel information. This reduces the bandwidth and associated power.
- Enables key features like OnDemand Pixels™ where only the active pixels are addressed, similar to LTPO, resulting in
- Power Saving: Only active pixels are touched so power is only burned for those active pixels.
- Performance Increase: Given the sparse nature of content for augmented reality (AR), we can focus all the bandwidth on active pixels objects. This allows for even higher frame rates for objects that do not take up the full resolution of the display.

Compound Photonics announced a partnership with specialty foundry GLOBALFOUNDRIES to produce the IntelliPix backplanes.
The IntelliPix platform is based on CP's OnDemand Pixels technology, which 'intelligently focuses only on changing pixels". This conserves power in inactive pixel regions and enhances image quality, according to the company. The company is leveraging GF's high-performance and ultra-low power 22FDX platform, the new backplanes will enable high frame rates, low latency, and low power consumption. CP says it expects the first commercial products based on its MicroLED micro display backplanes to be on the market in 2023. (Source: DSCC)
