Quantum Dot Television technology. Quantum dot televisions are coming to a living room near you Electronics manufacturer LG has shown off its new quantum dot television at a trade show in the US, and it’s expected to be available in 2016. The history of television is very old. There was a time when people use to witness TV black and white small TV sets. Then came the era of colour TV. This era was enjoyed by the people a lot. After this came the era of TV with woofer sound. Liquid-Crystal display television LCD TV are the television sets that use LCD display technology to produce images. They are thinner,lighter and are available in much larger sizes.LCD’s new and modified version was LED. A Plasma display panel (PDP) is a type of flat panel display common to large TV displays in 30 inches or larger.Since 3DTVs were first mass marketed back in 2010, we’ve been waiting for the next major break-through in television. According to scientists at Manchester University, this could be paper-thin OLED TV displays that incorporate quantum dot technology. Recently Scientists at Nanoco in Manchester,England, have created light emitting particles 100,000 times smaller than the width of a human strand of hair.Known as quantum dot technology, the light particles can be produced to emit any colour and printed onto flexible plastic to create ultra-thin televisions. The Nanosys technology is called Quantum Dot Enhancement Film (QDEF). It increases the color gamut (or number of colors) in a display by as much as three times without any increase in cost, size or power consumption.Nanoco said quantum dot technology offers better picture quality and lasts longer than traditional liquid crystal display (LCD) screens.This is the result of the Open Innovation experiment. It is an experience video showing the future of screen technology with stretchable screens, transparent screens and QD displays, to name a few. The company are working on small personal devices to begin with, but hope to develop bigger projects.“Something else we are looking at is reels of wallpaper or curtains made out of a material that has quantum dots printed on it,” a spokesman for Nanoco told the Daily Mail.Nanoco are reported to be working with major Asian electronic companies to produce the first quantum dot technology TV by the end of next year.The flexible screens could be in the shops within the next three years.Nanoco defines itself as “a world leader in the development and manufacture of cadmium-free quantum dots” at a time when being “cadmium-free” presents special advantage. Cadmium is generally used in LEDs in lighting and displays.The European Union has made it exempt, though,from its Restriction of Hazardous Substances (RoHS) directive due to the fact that there isn’t yet a practical substitute, according to eWEEK Europe. That exemption is to end in July 2014.“Our research and development department is also constantly engaged in the creation of new quantum dots with additional properties sought by the market, such as our RoHS-compliant heavy metal-free quantum dots,” says the company.
