Quantum dots will cascade into the marketplace. They offer lower cost, longer life, and brighter lighting, according to WinterGreen Research’s new study Quantum Dot and Quantum Dot Display (QLED) Market Shares, Strategy, and Forecasts, Worldwide, 2013 to 2019.
“The commercialization of quantum dots using kilogram quantity mass production is a game-changer,” said Susan Eustis, WinterGreen analyst. “High quality, high quantity and lowest price quantum dots increase product quality in every industry. The rate of change means speeded products cycles are evolving.”
Once manufacturers learn to integrate higher efficiency luminescent quantum dots into their products, each vendor will need to follow or dramatically lose market share, reports WinterGreen. This level of change brought by quantum dot and quantum dot displays (QLED) represents a new paradigm that will create new industries, products and jobs in science and industry. The list of possible quantum dot applications is ever expanding. New applications are waiting for the availability of more evolved quantum dots.
Quantum Dot LED (QLED) commercial focus has remained on key optical applications: Optical component lasers are emerging as a significant market. LED backlighting for LCD displays, LED general lighting, and solar power quantum dots are beginning to reach the market. Vendors continue to evaluate other applications.
Quantum dots QDs are minute particles or nano-particles in the range of 2nm to 10nm diameter. Quantum dots are tiny bits of semiconductor crystals with optical properties that are determined by their material composition. Their size is small to the nanoparticle level. They are made through a synthesis process. QD Vision synthesizes these materials in solution, and formulates them into inks and films. Quantum Dot LEDs (QLED) enable performance and cost benefits.
The quantum dot cannot be seen with the naked eye, because it is an extremely tiny semiconductor nanocrystal. The nanocrystal is a particle having a particle size of less than 10nm. QDs have great potential as light-emitting materials for next-generation displays with highly saturated colors because of high quantum efficiency, sharp spectral resolution, and easy wavelength tenability. Because QDs convert light to current, QDs have uses in other applications, including solar cells, photo detectors, and image sensors.
QLED displays are anticipated to be more efficient than LCDs and OLEDs. They are cheaper to make. Samsung estimates that they cost less than half of what it costs to make LCDs or OLED panels. QLED quantum dot display is better than OLED. It is brighter, cheaper, and saves more energy. Energy-savings is a strong feature. Its power consumption is 1/5 to 1/10 of the LCD’s Samsung offers now. Manufacturing costs of a display are less than half of OLED or LCD. It has a significantly longer life than the OLED.
QLED quantum dot display uses active matrix to control the opening and closing of the pixels of each color. Quantum dots have to use a thin film transistor. Emission from quantum dots is due to light or electrical stimulation. The quantum dots are able to produce different colors depending on the quantum shape and size used in the production of materials.
Dow Electronic Materials, a business unit of The Dow Chemical Company (NYSE: DOW) and Nanoco Group plc (AIM: NANO) have a global licensing agreement for Nanoco’s cadmium-free quantum dot technology. Under the terms of the agreement, Dow Electronic Materials will have exclusive worldwide rights for the sale, marketing and manufacture of Nanoco’s cadmium-free quantum dots for use in electronic displays.
