A new white paper on the use of Porotech microLED Technology
The third white paper in our Dynamic Pixel Tuning (DPT) series is now ready for downloading. This one focuses on the use of the DPT technology to make microLED-based small-area devices suitable for AR/VR applications.

This latest white paper first describes a generic microLED fabrication process to create a monolithic microdisplay for near-to-eye applications. Today, the best way to achieve a full-color single-display solution is to use quantum dots to convert some of the blue sub-pixels to red and green. With Dynamic Pixel Tuning, no quantum dot depostion is needed as each pixel can emit red, green, or blue light. The paper then describes some of the design advantages of using DPT pixels including the ability to achieve higher-density devices or devices with higher efficiency. A 0.26-inch demonstrator of the technology was shown at CES 2023 (see video summary HERE)
The first white paper describes technology developed by Porotech that can eliminate the RGB sub-pixel arrangement for displays and instead allow a single pixel to be designated any color in the visible spectrum simply by changing the drive characteristics. They call this invention Dynamic Pixel Tuning (DPT) and it appears to be quite a potential game changer.

The second white paper discusses the basics on large-area LED fabrication and assembly – typically from three different LED donor wafers for red, green and blue. Multiple mass transfer techniques have been developed, but at the microLED level, still remain low volume, costly or developmental.
The paper then discusses how microLED devices with Dynamic Pixel Tuning can offer multiple options such as pixel density, pixel efficiency, pixel layouts, integrations with additional components and sensors, or cost reduction. Some specific design examples help to clarify these options vs. existing microLED solutions.
