  • Patent number: 10929634
    Abstract: An operating method of a touch sensor includes sensing first touch intensities in a first touch-sensing area by using first touch cells, sensing second touch intensities in a second touch-sensing area that is adjacent to the first touch-sensing area by using second touch cells each having an area that is smaller than that of each of the first touch cells, grouping some second touch cells among the second touch cells as a touch-sensing group having a same area as one of the first touch cells, calculating a representative touch intensity of the touch-sensing group by using the second touch intensities sensed by second touch cells in the touch-sensing group, and detecting a touch position by using the first touch intensities and the representative touch intensity.

  • Patent number: 10496229
    Abstract: A touch sensor includes a plurality of driving electrodes, a plurality of sensing electrodes that intersect the plurality of driving electrodes, a driver configured to substantially simultaneously supply driving signals to at least some of the plurality of driving electrodes, a sensing unit configured to detect sensing signals from the plurality of sensing electrodes, and a touch controller configured to control the driver so that the number of driving electrodes to which the driving signals are supplied in a first driving period is different from the number of driving electrodes to which the driving signals are supplied in a second driving period.
