Demo: First public demo of Vivid Color in an LCD panel
At the Bay Area SID Emerging Materials Conference November 30th 2017
First public demo of an LCD panel using Vivid Color technology, at the Bay Area SID Emerging Materials conference, on Nov 30th at the Sheraton Hotel, Sunnyvale CA.
In the picture of the demo :
- Three 28" 4K UHD monitors were arranged together on a (Kanex 4-Port) HDMI splitter, to a single source (an Apple MacBookPro configured for DCI-P3 color-space display output) displaying wide-gamut images and UltraHD videos
- Left : the original (unmodified and default settings) QLED monitor. The backlight module is edge-lit with Blue LED's using Quantum Dot film. Measured output was 94.9% of DCI-P3 (by u,v area per CIE1976) using a ColorimetryResearch CR-250 NIST-traceable Spectroradiometer.
- Middle : Same LCD panel with the QDEF film removed, and the backlight replaced with standard YAG-phosphor-based White-LED backlight (equivalent to standard LCD panel). Measured at 79.7% of DCI-P3 (roughly same as an iPhone6 series)
- Right : Same LCD panel with the QDEF film removed, and backlight enhanced with Vivid Color VC65R. Measured at 92.7% of DCI-P3
- All displays were set to the same brightness level, with the measurement print-outs for each provided.
Attendees, were treated to a selection of wide-gamut images and 4K HDR videos, for side-by-side comparison.
Purpose: to illustrate what can be done in edge-lit LCD panel using our entry-level VC65R product, without QD films, or KSF. As a drop-in enhancement in the backlight-bar, without mechanical changes. Showing what's possible for wide-color gamut and high-dynamic range inside edge-lit LCD backlight module
1. Fits inside LED backlight module, but without the issues of narrow-band phosphors (like KSF's >10ms fluorescent-decay which is not HDR compatible), and without the flux-density limits reducing achievable brightness.
2. Without sensitive QD particles, heavy-metals or expensive thickness-adding encapsulated QDEF films (saving ~$60 in this example, more in larger screens).
3. UltraHD compliance in cheap prolific LCD, but with as good or better than OLED color gamut, and without the OLED screen burn-in, short lifetime and high-cost issues.
4. 100% made in USA, from US materials
UltraHD requirements : See the UHD Alliance requirements, published at http://uhdalliance.org , in summary the Logo needs:
- More Colorful : >90% DCI-P3 wide-color gamut (both UltraHD & MobileHDR logo's)
- Brighter : 540nits (OLED), 1,000nits (LCD), to 10Knits (BluRayUHD)
- Higher dynamic range : ≥20,000:1 (UltraHD Premium) or ≥6,000:1 (MobileHDR Premium)
- Better fidelity : 10bits per component using EOTF2084

Application example: thin portable devices aiming to achieve the UltraHD or MobileHDR logo requirements, using prolific edge-lit LCD panels. To enhance the color gamut, and dynamic range, without increasing bezel size, introducing thicker films layers, or simply retrofitting existing designs.
Other display and lighting applications are possible - everywhere that needs bright, tunable color, light
Vivid Color(tm) : No Quantum Dots. No QDEF films, or KSF. Zero Heavy Metals. Just bright, HDR-compatible, tunable color.
Rethink what's possible.
