Distec Optimizes Interfaces for Modern Embedded Systems with Touch

Distec – leading German specialist for TFT flat screens and system solutions for industrial and multimedia applications – now provides high quality touch solutions with I²C interface, which are 30 to 40 percent cheaper than comparable USB versions. Featuring a very sleek design and a black mat rear printing, they are available in sizes of 5″, 7″, 10.1″ and 10.4″ diagonal. “Compared with RS232, the I²C-based touch systems work with a very high speed of 3.4 Mbit/s and are extremely energy efficient with a supply voltage starting at 1.2V,” stated Matthias Keller, COO Components at Distec. “The power consumption is extremely low. Therefore power supplies, batteries in handheld devices and the corresponding peripheral circuits can be very compact.” This saves space, weight and cost through reduced cooling effort and also increases the life time due to the lower heat load of all components within the system.

Customer’s Benefit with I²C Interface

Another advantage of I²C is that there are no license fees required. This makes the I²C ICs significantly cheaper than USB or combined solutions. With the appropriate chip selection the costs can be reduced by another 30 percent without any sacrifice in functionality. On a project basis, other sizes currently up to a maximum of 24″ can be implemented. For shapes, colors and logos there are virtually no restrictions offering a complete bespoke touch screen solution. To enable a professional and fast design-in support for the I²C hardware, Distec’s engineers have already prepared several implementations for various Linux kernel versions and for Android. Appropriate driver binaries, config files and sample scripts can be provided and adaptions to specific customer’s requirements are carried out quickly and efficiently.

Distec will present the high quality touch solutions with I²C interface at stand 210 in hall 8 at SPS/IPC/DRIVES from November 25 to 27,2014 in Nuremburg, Germany. For more information, please visit http://www.distec.de.
