Abstract
Official abstract text for this publication.
A capacitive touch system uses two or more integrated circuits to simultaneously scan a touch panel in such a manner that each of the integrated circuits scans only a portion of the touch panel to retrieve a respective detected data by itself. All the detected data are used for computation by one of the integrated circuits or one other than the integrated circuits to determine a touch information. This approach enables axis intersect projected capacitance touch integrated circuits applicable to a large scale touch panel, without degrading the frame rate of a capacitive touch system.
First claim
Opening claim text (preview).
What is claimed is: 1. A capacitive touch system, comprising; a touch panel formed of a single panel having a plurality of traces; at least a first integrated circuit connected to the touch panel formed of a single panel, the first integrated circuit scanning a first portion of the touch panel by charging or discharging the traces of the first portion to retrieve first detected data; and a second integrated circuit connected to the touch panel formed of a single panel and the…
