Some of the interesting topics at the Quantum Dot Forum. I saw BOE in the mix. We haven't heard anything about them integrating quantum dots yet, but appears they are. They are another large Chinese company.

Quote:
Emerging Chinese manufacturer BOE squeezed out Japanese vendors to become the world’s second largest vendor, while ranking in third is Japan Display Inc. (JDI). In fourth place is Chinese company Tianma, and LG Display global rankings tumbled from top three to five.

Quantum Dot Application in Display

Guangkui Qin | Senior Researcher of BOE

Quote:
This presentation will be divided into three parts. First part is recent development trend of the display industry; the second part is applications of quantum in display and the new development; the third part is plan of BOE about display busyness.

The Last Mile Problem - Challenges Facing Quantum Dot Integration into the Ever-Changing Landscape of Display Components

Matt Bertram | Director of Operations of Quantum Materials Corporation

Quote:
The display landscape is always changing. Display brands, device manufacturers, and component suppliers all demand increases to color gamut, brightness, and dynamic range. These demands present ever-changing integration issues for quantum dot manufacturers and applications teams. This talk will cover current integration challenges and strategies quantum dot firms have made to overcome them, i.e. films and remote down-converting components. A forward looking and first principled analysis for next generation components will be detailed, e.g. on-chip, filter augmentation/replacement and electroluminescence.

Spectrally Narrow Red Quantum Dots in White LEDs for General Illumination

Ken Shimizu, Director, Novel Technologies and Devices, Research and Development, Lumileds, LLC

Quote:
Quantum Dots have shown promise of delivering high luminous efficacy of radiation in LEDs based on the spectrally narrow and fully tunable wavelength of its fluorescence emission. An on-chip converter application is preferred over remote configurations as it provides the lowest cost and lowest complexity for LED use in various lighting and display applications. We compare QD material readiness for applications ranging from remote and vicinity phosphor to on-chip arrangements

Exploring the Bounds of Narrow-band QD-converted LEDs

Juanita Kurtin Ph.D | CTO and Founder of Pacific Light Technologies

Quote:
Quantum dots (QDs) are finding increasing commercial success in a variety of LED applications. While they have been used for several years in a remote off-chip architecture for display applications, for the first time Pacific Light Technologies, in collaboration with its LED packaging customers, has shown that quantum dots can withstand the demands of the on-chip architecture and therefore are capable of being used as a direct phosphor replacement in both lighting and display applications.

It is well known that to achieve improved color metrics in lighting as well as increased gamut in display technologies, it is highly desirable to utilize a QD downconverter with a narrow emission linewidth as well as a precisely tunable peak. This paper will discuss the results of use of quantum dot-converted LEDs in a lighting product, and explore the opportunities and practical limits for improvement of various lighting and display metrics by use of this unique on-chip QD technology.

Development of an Air-Stable and Thermally Processable Sapphire™ Quantum Dot Polymer Matrix Using a Two-Prong Approach

Matt Bootman | CEO of Crystalplex Corporation

Quote:
Semiconductor nanocrystals, also commonly called quantum dots (QDs), are attracting widespread attention as down-converting films because of unique optical properties, including emission wavelengths in the visible range, high quantum efficiency, narrow emission with wide absorption profiles, and compatibility with custom matrix polymers. Recent advancements have opened opportunities for QD/polymer composites for on-chip and near-chip applications of QD-LEDs, replacing traditional phosphors. Dispersion in a custom polymer requires 1.) modifying the surface of the QDs to isolate them from the degrading effects of oxygen and water vapor, and 2.) developing a custom host polymer matrix optimized for the QD surface interaction.
