发明名称 INPUT DEVICE
摘要 An input device includes a plurality of X scan electrodes, a plurality of Y scan electrodes, and common detection electrode forming capacitance with the X scan electrodes and the Y scan electrodes. In the cycles, a second driving signal is supplied to the same Y scan electrode, and in each of the cycles, a first driving signal is sequentially supplied to the X scan electrodes. Two positions touched by fingers are detected from detection current to be obtained by the detection electrodes.
