Abstract
An multi-touch detection system (100) separately determines each of the coordinates of multiple touches and is able to correctly pair the coordinates, the touch panel includes multiple (e.g., two or four) separate sections (104, 106, 404, 406, 504, 506, 508, 510) to detect touches in different areas. The system (100) is able to operate at high refresh rates allowing speed sensitive applications to be supported.
