Just this year, global demand for products similar to the greedy touch off a touch screen like the sharp rise in the market. With a wider range of mobile applications, and new "must have" products, inventions, is difficult to predict the growth trend will be mitigated or growth. But regardless of slowing down or the up, touch panel display technologies have become a permanent member of the family.
John Bush often amazed over the past few years, the touch screen market. Three years ago, he became Applied Materials, Inc. is located in Germany, winding type coating (roll to roll vacuum coating equipment) division director. When they spend a lot of energy in flexible electronic products, the opportunity to find a variety of applications such as flexible solar panels, displays, printed circuit boards as well as several applications based on transparent conductive films, Zinc oxide including touch screen devices. The irony is that despite many years of dedication to their team in this market, and since the early eighties has been selling Roll-type indium tin oxide (ITO) sputtering equipment, but because of resistive touch technology market growth is limited, relatively small and has been tepid.
Until the multi-touch technology used in products such as mobile phones and tablet PCs, touch screen was a change in the slow stabilization of the market state. Projected capacitive touch technology, because of its excellent multi-touch performance, setting off a new round of production capacity in manufacturing boom. Initially, the industry has a color film process production line manufacturers have converted the product line, Titanium dioxide with both equipment touch screen products;, they can be applied to flexible substrates resistive touch screen and projected capacitive touch screen manufacturing SmartWeb roll to roll type coating sharp increase in market demand for the device, while the last two years, their touch-screen device for the production of tailor-made NewAristo and AKTAristoTwin new record high performance coating equipment, show the market for film-based touch-screen glass substrate and robust growth in demand .
In 2010, he began to show as Applied Materials PVD Products Business Group General Manager, continue to surf in the area of ​​touch technology, but also via in another way, which is based on touch screen technology the glass substrate. From the touch technology level, the process to repeat itself two devices, both mechanical design and equipment is extremely different. Similar in that both use the most advanced of the ITO coating technology, combined with additional films are used (such as SiO2, metal, etc.) and ways to improve ITO properties are projected capacitive touch screen for the production, Magnesia and ultimately for the phone and tablet computer products. However, the two devices is very different substrate handling device (a single piece of glass is moving, one is roll to roll flexible substrate handling), and the optimization of thin film optical properties and application has been run in each direction. For example, the flexible plastic substrate of the touch-screen device is thinner, lighter, more resistant to shocks; and glass touch-screen devices will have better light transmission rate of greater scratch resistance. Of course, the two methods are proactive and strengthen the short-board improvements, the glass substrate becomes thinner and lighter, more transparent and flexible substrate, and by the way continue to strengthen coating surface hardness.
Although the two kinds of flexible substrate and glass substrate touch the existence of different products, but two ways to function in an integrated thin-film multilayer technology to advance the industry in technological innovation. Nickel oxide Projected capacitive touch screen requires the production of transparent conductive film (eg ITO) to make a graph lines. While touch-screen graphics technology than semiconductor or liquid crystal display graphics technology is relatively simple, but they can be identified out of the eye (but for the ultimate in display quality and the use of graphics technology and equipment they need not). Visible lines to solve problems the way through the film stack, while maintaining the optical properties of the touch screen device's overall performance and can make the visual lines in the pattern can be hidden. Even better, superimposed over both the anti-reflective film feature film, so that the display device to become a better visual experience. Using PVD (sputtering) coater Another advantage is that you can use the same equipment deposit ITO, SiO2 and / or metal film, for end-product manufacturers will have the opportunity to reduce the consumption of additional material and subsequent process steps, such as putting film or wet coating process.
Future full of possibilities, a variety of exciting new technology will support the rapid development of the touch screen industry, continued to show dynamic growth. Source:http://www.mhcocm.com
