Abstract: The present invention is directed to a drive system adaptable to a matrix scanning device. A number of first drive circuits are disposed on a first periphery along a first direction of a substrate with each said first drive circuit being coupled to at least one column wire of the matrix scanning device. A number of second drive circuits are disposed on a second periphery along a second direction of the substrate with each said second drive circuit being coupled to at least one row wire of the matrix scanning device. A master controller controls the first drive circuits and the second drive circuits. A bus is electrically coupled to the master controller, the first drive circuits and the second drive circuits.

Abstract: A programmable controller used in a touch sensing device comprises a plurality of general pins, a control circuit, and a plurality of switching units. The control circuit records corresponding relationship between a plurality of general pins and a plurality of sensing lines and driving lines of the touch panel. The switching units are correspondingly connected with the general pins, and separately receive a switching signal produced by the control circuit, wherein the control circuit produces the switching signal based on the corresponding relationship, and wherein each of the switching units selectively connects the correspondingly connected general pin to a sensing circuit or a driving circuit based on the received switching signal. The programmable controller can be for designers to set the corresponding relationship between the general pins and the driving lines and the sensing lines, such that the programmable controller is applicable to different standards of the touch panel.
