Realfiction Holding AB announced that it will demonstrate four versions of its Directional Pixel Technology ("Directional Pixel Technology" or "DPT", formerly known as Project ECHO), enabling home cinema-sized glasses-free 3D displays for up to 5 persons (10 views) at the same time with 4K resolution, during the Consumer Electronics Show (CES) in Las Vegas in January 2024. While impressive single user 3D displays for tablets and notebooks have been shown before, the world is still waiting for the first large, multiuser, high quality naked-eye 3D display. Realfiction believes its novel time- multiplexing holds the key to achieving this, and the Company is proud to unveil a range of DPT display demonstrations based on LCD, OLED and MicroLED during the CES week.

The four DPT demos to be demonstrated during CES include a 17-inch Multiview LCD display and a 17-inch 3D Multiuser LCD display (both scalable to large TV sizes), a small segment of a 65-inch OLED 3D Multiuser display (scalable to large TV sizes/home cinema), and a 2-inch HybridScan MicroLED proof-of-concept (scalable to largeTV sizes/home cinema when large-size microLED displays become commercially viable). All technologies are ready for licensing, and Realfiction is currently pursuing commercial licensing deals and/or collaborations to enable mass manufacturing.

The multiview feature comes as a natural part of any 3D DPT display but can also be made simpler for 2D only. This can be relevant to increase safety and entertainment in automotive, and for applications where privacy or differentiated view is either a need or a benefit. A 17-inch 3D multiuser demo showing that the DPT technology is unique in its capacity to show 3D content to more than one user at a time, even without lowering the screen resolution to half or less, which is the normal approach with glasses-free 3D display technology.

While shown on a 17-inch display, the technology can be scaled up to large TV sizes.

This OLED version demonstrates a segment of a 65-inch 4K display suitable for home cinema use, and scalable to even larger sizes.

The OLED version is capable of showing different content for 5 3D viewers or 10 2D viewers at the same time with no loss of resolution. A 2-inch MicroLED proof-of-concept that effectively demonstrates how the DPT time- multiplexing driving system is capable of showing different content for 5 3D viewers or 10 2D viewers at the same time on a MicroLED display, with a refresh rate of 130 frames per second for each view and no loss of resolution.
