QDs are minute particles or nano-particles in the range of 2 nm to 10 nm diameter. Since their breakthrough in 1980, quantum dots have been weathered in diverse conditions and operations, which have resulted in the extraction of their unique properties. Due to their controlled excitation properties and ability to reflect in three dimensions, they can be easily tuned to provide the desired emission wavelength just by changing their core size called as “size quantization effect”. Their physical properties do not depend on the material from which they are prepared but on their size. Their notable property of absorption and transmission has evolved them as the desired material to be used in the field of optoelectronics and biomedical applications.
One of the major segments developing in the field of Quantum Display is QD Displays (QDD). A QD display provides better features as compared to cathode ray tubes (CRT) and liquid crystal displays (LCDs).This technology is similar to organic light emitting diode (OLED) that provides more efficient displays. QDD provides 50 to 100 times better brightness in comparison with CRT display and LCD. LCD does not produce a pure green, red, and blue color. On the other hand, Quantum Dot Display produces pure colors.
QD LED and QDD are expected to get commercialized by the end of 2012, as there is strong R&D is going on in this field and solid-state lighting. However, companies have launched QD LED lamp, but the current market for QD LED lamp and the other lighting products is very small. QD-based lighting will be the best replacement for currently available CFL and LED lighting, as this provides better efficiency and high power intensity. QD solar cells and panels will be the biggest revolution in the field of solar energy, and they are expected to commercialize by 2014.
Healthcare industry is one of the key areas of QD technology. There are numerous applications in biomedical and biotechnology field that are already exposed to QD technology and hence it is accounted for the largest percentage in QD market on the whole. Applications in biomedical and biotechnology fields are expected to increase as technology progresses.
The overall market for QD technology is expected to grow at an estimated CAGR of XX% from 2012 to 2022, with healthcare industry having the largest market share. At present, Americas are the market leader, but by the end of 2022, APAC is estimated to take over the first position.
