  • Patent number: 10754469
    Abstract: An apparatus for detecting a touch includes a touch panel configured to include an electrode constituting a self-capacitor together with an object, a charge-sharing unit configured to include a charge-sharing capacitor which is charge-shared with the self-capacitor, a differential signal generation unit configured to receive an output signal of the charge-sharing unit, generate a pair of pseudo differential touch signals, and detect a touch of the object, and a control unit configured to control the charge-sharing unit so that the charge-sharing unit may perform charge sharing and signal output.

  • Patent number: 10345947
    Abstract: Disclosed is a method of detecting a hovering object, the method including: an operation of precharging a compensation capacitor and a parallel capacitor, which is obtained by connecting in parallel a self-capacitor formed between an object hovering over a touch panel and an electrode of the touch panel and a parasitic capacitor of the touch panel, with a predetermined voltage; a first charge sharing operation of sharing charges by connecting the parallel capacitor and the compensation capacitor in series; a second charge sharing operation of sharing charges by connecting the parallel capacitor and the compensation capacitor in parallel; and an operation of outputting an electrical signal provided by the parallel capacitor while the parallel capacitor and the compensation capacitor are connected in parallel.
