It is naïve and ignorant to say there is no deman

NN Labs has Online QD sales just like QMC does, if it sold only few grams a year just like an idiot said, it would be out of business, but it is still striving. It is hard to find out its annual quantum dot sales as it is private.
Global quantum dot demands will hit $4.6 Billion by 2021

In 2002, Xiaogang Peng, a professor of chemistry and biochemistry, synthesized nanocrystals in suspension using environ-mentally friendly methods that had not been seen before. Shortly thereafter, he founded a company at the Arkansas Research and Technology Park to examine possible applications for these nanocrystals.
Peng recently returned to China, but the company he founded, NN-Laboratories, continues to do research and development in Fayetteville. The company also has a subsidiary called NN-Crystal that specializes in applying the technology to lighting.
The nanocrystals can power solid-state lighting used commercially. Lighting consumes more than 20 percent of the energy used worldwide, and most current light sources are inefficient: An incandescent light bulb is about 1-3 percent efficient, while fluorescent light bulbs are about 20 percent efficient. In contrast, solid-state lighting, also known as LED lighting, can be up to 50 percent energy-efficient. Furthermore, this LED lighting lasts much longer than standard bulbs: Incandescent bulbs last about six months, fluorescent bulbs anywhere from a few months to three years, and LED lighting can last up to 10 years.
“Imagine a hotel lobby in Las Vegas. There, the cost of a light is trivial compared to the cost of replacing those lights,” said Suresh Sunderrajan, president of NN-Crystal.
Despite their increased efficiency, LEDs have proved a challenge, because they are monochromatic — they do not emit white light, which is a combination of all types of light. Instead, they can only emit colors like red, blue and yellow. LEDs are made to produce white light by combining a blue LED with a yellow phosphor, a substance that glows when exposed to electrons. The combination of blue and yellow makes white. The quality of white light produced this way is poor, however, with relatively poor color rendering ability.
“This can cause a blue jacket to look gray, for instance,” Sunderrajan said. High-quality light mimics sunlight, the human’s natural standard, and the light from LEDs is not considered to be of high quality unless other colors beyond blue and yellow are added, which cuts back on the light’s overall efficiency – the light may look better, but the amount of light emitted is lower for the same amount of energy.
“We fix that problem with our technology,” Sunderrajan said.
NNCrystal has created a technology called Qshift Coral, which uses quantum dots to precisely control color. They can be used to augment the color of light emitted by LEDs to produce high-quality white light without sacrificing efficiency. Since these quantum dots are tunable – the optical properties can be controlled to change the color of light they emit – the lights can be “tuned” to create almost any other color or color combination on the spectrum.
The second technology being introduced by NNCrystal, Qshift Lucid, features nanoparticles that are color-free in ambient lighting and can be combined with different LED lights, yet will look clear like traditional lights when turned off. This technology can be used to build all of the colors in the sun’s spectrum.
“It’s just like having the sun indoors,” Sunderrajan said.
The company demonstrated the technologies at Lightfair 2010, the lighting industry’s trade show. Their technology caught the interest of Renaissance Lighting, a company that was recently bought by Acuity Brands, which has about $1.6 billion in annual sales.
Qshift Coral is available commercially now, and Qshift Lucid should be available next year.
The company employs 15 people, four of whom have doctoral degrees in optical physics, polymer engineering and synthetic chemistry.
“The focus of the Arkansas lab is taking an idea from its synthesis to proof of concept,” Sunderrajan said.
Beyond lighting, NN-Labs is looking at advanced applications in the life sciences, such as medical diagnostics, as well as possible use to enhance the performance of solar cells.

If NN Labs had thought of QD application in TV display and had invented continuous flow mass QD production, it would be competing with OLED and working side by side with QMC.
