TITLE: Bringing Better Pixels to UHD with Quantum Dots

SPEAKER: Dr. Charlie Hotz, Vice President of R&D, Nanosys



Advances in Quantum Dot chemistry and synthesis have made them an ideal emitter for backlight units in LCDs, with over 25 retail SKUs using Quantum Dots now available ranging from 7” tablet size up to 85” TV size. The next wave of technology innovation in displays is upon us now with Ultra-High Definition, whose most well-known benefit is an increase in resolution from HD to 4K, but there is much more to this new broadcast specification. High dynamic range (HDR) and wide color gamut (WCG) bring more perceptible benefits to users in terms of an improved viewing experience than improved resolution alone.
The ultra-high color gamut standard adopted for UHD broadcast, known as Rec. 2020, was originally defined for laser-based projectors where the color primaries are on the color locus of the CIE diagram. Due to the deeply saturated color coordinates, Rec. 2020 is beyond the capabilities of OLEDs and conventional LED backlit LCDs. So is the Rec. 2020 color standard reachable for consumer displays or is it only for high-end laser-based projection systems? This presentation will explore the capability of using quantum dots in LCDs to reach the ultra-high color gamut of Rec. 2020.

Dr. Charlie Hotz sets the vision for Nanosys’ design, invention of new products and development of existing products. Dr. Hotz has been with Nanosys for 2 years and has developed the company’s large-scale QD synthesis processes and equipment, including working with all the regulatory bodies such as the EPA and local jurisdictions.

Prior to Nanosys, Dr. Hotz was Vice President, R&D for 6 years at Solexant, a QD based photovoltaics company where he develop the first ever high efficiency QD solar cells.  Dr. Hotz also served as Vice President of R&D for 7 years at Quantum Dot Corporation, where he developed many QD products for diagnostic and biological applications which are still in use today at Thermo-Fischer, who acquired Quantum Dot Corporation.  Charlie has a Ph.D. in Chemistry from Michigan.
