  • Multipoint locating method and device on touch screen with single conducting layer
    Patent number: 10025488
    Abstract: Multipoint locating method and device on a touch screen with a single conducting layer are provided. In the method, if there is a minimum detection unit with a capacitance variation amount greater than a preset condition to be partitioned, partitioning out a calculation matrix corresponding to the minimum detection unit to be partitioned. Therefore, multipoint locating on a touch screen with a single conducting layer is implemented.
