Abstract
There is disclosed an apparatus for detecting touch including a touch element comprising a plurality of touch detecting electrodes arranged therein, a touch element controller for acquiring detection signals from the touch detection electrodes and determining presence of touch in the touch element, wherein the touch element controller includes a receiving unit for receiving the detection signals from the touch detection electrodes and grouping the detection signals into one or more detection signal groups, a memory for storing a detection signal value limit, a signal extracting unit for extracting the maximum detection value out of the detection signal values of the detection for each of the detection signals, a calculating unit for calculating an adjustment variable by deducting the detection signal value limit from the maximum detection signal value for each of the detection groups, and a touch determination unit for determining presence of touch in the touch element, using the adjustment variable.
