Invented a simple and cheap way to produce touch screens in the home

In Honolulu (Hawaii, USA) this week 27th international Symposium on INTER Software and Technology, which was shown new and very interesting technologies and prototypes. Portal Gizmodo notes that, among other things, the exhibition was shown a technology that allows to print a simple and cheap touch screens on printers.

The technology is called PrintScreen. It allows you to create touch screens on the basis of almost any material, including wood, Mylar, marble, leather, metal, and even on an ordinary sheet of office paper. The technology allows very fast and cheap to produce touch displays at home. Moreover, the displays can even be bilateral, they can twist into a tube or folded.

In the words of the guys who created the described technology PrintScreen, the process of production of flexible displays (including touch-based) typically requires a "high-tech print lab, complex devices and special skills." However, using the technique of printing on the basis of their technology, the process becomes much easier and cheaper.

In the published article, won the award for "Best scientific article of the exhibition", the authors Simon Olberding, Michael Wesley and jürgen Steimle explain how they were able to realize your project.

Usually are developing a prototype device with a display looks like this:





However, three of the engineers proposed a more simple approach starting with the development of a simple design of an electric circuit in a usual image editor for PC. Having a vector image of the required components, print the file on any ordinary inkjet printer. The most important part of this process is what ink (and in what sequence) are used for printing the future of touch screen. The printing of such ink comes in four layers: the first layer is the silver conductor, then a layer of dielectric, then the layer of phosphor and in the end a layer of a translucent conductor. The essence is that, being located between two conductive layers, the phosphorus by passing a current through the ink begins to glow.

In the published article, the inventors have shown five prototypes. One of them, for example, is a touch watchband. Another prototype is an artificial plant on a sheet which caused the touch screen, clicking on which a person can answer incoming calls on his phone. In addition, it was shown the prototype, where when you add additional components, you can get a more complex product.













Presented prototypes to show just some of the capabilities of the new production technology of touch screens, and who knows what else can come up with, do it in mass production. The possibilities can be really endless.
