In connection with the termination of the natural reserves of indium producers of smartphones, tablets and touchscreen laptops to master the production of touch screens based on other materials. Manufacturers of smart phones, tablets and other modern electronics in the coming years to develop new materials from which they will be releasing a touchscreen because natural resources a key component of modern displays - metal indium - may soon end. This issue was discussed at the last San Francisco industry conference Semicon West. In modern touch screens film is indium tin oxide, through which depression is registered. This material is used because it has high transparency and conductivity. Develop new materials manufacturers need an industrial scale in the coming years, given the rate of growth in output of sensor devices, stresses GigaOM. According to NPD DisplaySearch, in 2013 the total area of touch screens in all of the issued units increased by more than a factor of 2 - to 25.5 million square feet. m, compared with 12 million square feet. m in 2012 is expected that by 2015, the area will increase to 35.9 million square feet. m The demand for touch screens also significantly increased due to the growth of the market of touch laptops, analysts say.
