Abstract
There are a touch input sensing device and a touch input sensing method. The touch input sensing device includes: a plurality of sensing electrodes; and a controller obtaining sensing signals generated from the plurality of sensing electrodes through a plurality of sensing channels electrically connected to the plurality of sensing electrodes, wherein the controller calculates a difference value between the sensing signals obtained from the plurality of sensing channels connected to the mutually adjacent sensing electrodes among the plurality of sensing electrodes to determine a touch input. A weighting value is assigned to a difference value between sensing signals obtained from mutually adjacent sensing electrodes, based on which the coordinates, or the like, of a touch input are determined, thus significantly reducing the influence of noise and accurately determining a touch input.
