Vivid Color Technology Exceeds Quantum Dot and OLED Color Gamut

PixelDisplay is introducing Vivid Color technology, a new approach to improving the quality of the display experience, on smartphones, tablets, computers, TVs, VR, AR and digital signage. Retaining the key benefits of (inorganic) LEDs and extending to include:

  • Ultra-wide color gamut display applications. Far beyond existing white LEDs, HighGamut-LEDs, or 3-chip RGB LED solutions
  • Multiple primary-colors; tunable wavelength and width. From an energy-recycling, space-saving, single-chip design
  • Longer lifetime, lower system cost, better stability, thinness and system energy-efficiency than previous alternatives
  • Leverages existing manufacturing processes and infrastructure
  • Zero heavy metals. Fully RoHS compliant.
  • Other applications: Holographic displays without lasers, custom spectra lighting for agriculture, blue-reduced streetlights

"Portable consumer display devices face a challenge: the dynamic, colorful experience of the new UltraHD content is very compelling," says David Wyatt, Chief Technology Officer of PixelDisplay. "But makers of these products find it difficult to swallow the TV display solutions for achieving better brightness, dynamic range and color gamut. QD films and QD light bars add thickness, can lower efficiency, increase bezel-size or leak blue-light, and even the latest RoHS compliant QDs still contain some Cadmium. The OLED alternative is expensive to manufacture, not as bright and exhibits shorter lifetime. And while AR-VR applications need better quality pixels, and more of them, the use of lasers in some AR solutions (for holographic 3D-displays) has already raised concerns about the risks of eye-injury.

"Phosphor-converted LEDs have been the most robust solution, but the challenge has been producing better color purity, without sacrificing power. Meanwhile Japan is already 4x beyond UltraHD, with 8K. With only a laser-based display having achieved 98% of the new 8K color gamut (BT.2020), which is ~40% larger than the UltraHD color gamut (DCI-P3)," Wyatt summarizes. 

PixelDisplay is demonstrating a new approach with twice the color-purity of QDs, that could be used to achieve 97.8% BT.2020, according to its maker. They add that this option has the potential to go beyond OLED and heavy metal QDs, to match lasers in display color gamut and more, without the laser-speckle-artifacts, or eye-damage warning label.

For more details, see David Wyatt's presentation #67-4, "Ultra-Wide Gamut LCD using Vivid Color Technology," nominated for Distinguished Paper, on Thursday, 25 May, Room: 502B at 4:00 PM, during the technical symposium at the Society of Information Display's (SID) DisplayWeek tradeshow in Los Angeles, California (US).

PixelDisplay is also demonstrating a prototype Vivid Color LED light-source, as per the paper, at SID's Innovation-Zone booth #7, from 23–25 May.
