  • Patent number: 9423906
    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.

  • Patent number: 8754871
    Abstract: The present invention provides a capacitive touch sensing device and a scanning method thereof. The present invention divides a scanning procedure of an electrode matrix into two stages. First, it scans broadly for determining whether the potential signal of at least one driving line of the electrode matrix is changed or not. After that, the present invention is only directed to the driving line which the potential signal is changed to scan in detail, to determine whether the potential signal of each coupling node on the driving line is changed or not. Therefore, the present invention can achieve the purpose of improving sensing efficiency of the capacitive touch sensing device.
