Swedish touchscreen developer FlatFrog has closed a €20 million funding round led by Intel Capital and backed by private equity firm Invus.

FlatFrog plans to use the funds to expand its team and to push forward the development and commercialisation of its multi-touch technologies.

One such technology is Planar Scatter Detection (PSD), an optical in-glass technology which supports more than 20 simultaneous touch inputs and can be scaled from 3 inch to 100 inch displays.

Optics trickery

Since PSD is based on optics rather than capacitive technology, FlatFrog's displays can detect input from gloved fingers, passive stylus pens, and many other common objects.

The company has recently released its first product based on said technology – the 32 inch FlatFrog Multitouch 3200 – and it plans to release larger displays to meet consumer demand.

FlatFrog has also developed a PSD multitouch kit for OEM manufacturing, which it envisages being used in tablets, laptops, and all-in-one computers.

Touch revolution

"Since we began developing our unique multi-touch technology more than five years ago, our goal has been to bring supreme multi-touch technologies to the mass market by providing flawless user experiences at affordable prices," explained FlatFrog's CEO and founder Christer Fåhraeus.

"Creating a perfect touch experience at very low price-points, in a way that is easy to manufacture and that can scale from small to very large sizes, is extremely complicated.

"We literally have had best-in-class scientists working for years on our algorithms, opto-electronics and opto-mechanics. This new financing round will take us to a new level."
