Stantum Technologies has introduced a dual-chip high-resolution architecture for its patented Interpolated Voltage Sensing Matrix (IVSM) touch-and-write technology for use in multitouch panels.

The architecture is based on two hardware enhancements that enable OEMs to produce high-resolution touch panels with half as many controller chips as the previous architecture, thanks to a new breakthrough scanning engine, which is part of Stantum's PMatrix IP core and firmware.

The architecture also lets designers choose between a new chip-on-board-based controller and BGA-on-motherboard options.

"High-resolution touch panels can now be designed with only two chips for a 10.1-inch display, as opposed to four chips previously," says the Stantum CEO, Robert Pelissier, at the Society for Information Display conference.

IVSM technology supports Windows and Android operating systems on x86 and ARM-based platforms and lets OEMs design tablet displays that allow as many as 10 simultaneous touches combined with high-resolution handwriting input. IVSM touch modules are offered through Stantum's Qualified Manufacturers Partners, comprising tier-one touch-screen manufacturers with high-volume production capabilities.
