Dialog touch chip supports Microsoft, FlatFrog
FlatFrog Laboratories AB, founded in 2007 and backed by Intel Capital amongst others, has developed a patented optical in-glass technology that supports multi-touch sensing and can assess how hard someone is touching, based on the spreading of contact surface area.
FlatFrog Touch supports up to 40 simultaneous touches with pressure detection and the technology is expected to have applications in mainstream consumer electronics as well as in digital signage, education, automotive, gaming and medical displays.
Although optimized to support Microsoft Windows 8.1, the DA8901 is also suitable for use with Android-based touch-enabled operating systems.
FlatFrog Touch uses in-glass infrared light, which is injected into the screen and detected along the edges. IR light information collected at multiple sensors at the edge of the screen can not only detect the precise location of touches but also provide up to 10 bits of touch pressure resolution. The system can track multiple touches and gestures and works with multiple objects including gloved hands or a stylus.
DA8901 comes in a 5.7mm by 5.0mm QFN package and is suitable for mounting alongside infrared LED emitter and receiver components on a narrow printed circuit board.
