摘要:
A touch detection device includes: a plurality of drive electrodes; a plurality of detection electrodes intersecting the plurality of drive electrodes, and each outputting, in response to driving of each of the drive electrodes, a series of detection signals; a signal correction section determining a reference based on the detection signals, and subtracting the determined reference from each of the detection signals; and a detecting section detecting an external proximity object based on corrected detection signals provided from the signal correction section.
