  • Touch detection method and touch detection apparatus
    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.
    Type: Grant
    Filed: July 4, 2017
    Date of Patent: August 25, 2020
    Assignee: MELFAS INC.
    Inventors: Byung Sang Rhim, Jae Woo You, Min Suk Woo
  • Capacitance detection method and capacitance detection apparatus using the same
    Patent number: 10641805
    Abstract: Disclosed is a capacitance detection apparatus including a panel, having a parasitic capacitor formed therein, and an electrode that forms, in operation of the apparatus a self-capacitor with an object; a compensation capacitor configured to share charges with the parasitic capacitor and the self-capacitor to output a detection signal with compensation for an influence of the parasitic capacitor; a switch unit including a plurality of switches which get turned on or off so that the compensation capacitor compensates for the influence of the parasitic capacitor, and an output voltage adjusting unit connected to the compensation capacitor and configured to adjust an output range of the detection signal output by the compensation capacitor.
