The flow of news and rumours related to iWatch is constant , there is no day that we don’t have some kind of news related to it. And if two days ago we were talking about a supposed ability to predict heart attacks, this time it’s time to talk about the type of screen it will be on.
Apple could have chosen the company TPK as the supplier for the touch panel of the rumored iWatch . This company, based in Taiwan, is supposed to start mass production of flexible AMOLED panels in the second half of 2014, which would mount the iWatch together with a 3D glass for curved panels.
Apple could use in these conductive panels based on silver nanowire. Currently the conductive materials used in the panels are based on tin and indium, specifically indium tin oxide (ITO), but the manufacturing process is quite expensive and indium is very scarce, and the more so this material cannot be used to develop flexible equipment. Silver nanowires are very thin, between 40 and 250 nanometers, and can be applied to a curved surface .
Last year, TPK signed an agreement with Japanese company Nissha Printing to start producing silver nanowire touch screens . Manufacturing will take off in the second quarter of this year, with a production rate of two million touch panels per month.
TPK is one of the world’s leading manufacturers of touch panels , and has supplied panels to Apple for several years. The Taiwanese company was a major supplier of the original iPad touch screen and provides up to 80 percent of the panels for current iPhone 4s models, so it wouldn’t be unreasonable for it to be the final choice.
