US Patent 11907459 Touch detection device

According to an aspect, a touch detection device includes: drive electrodes, a drive signal being input to each of the drive electrodes; and a first drive electrode included in the drive electrodes and divided into subdivided electrodes. An arrangement pitch of the subdivided electrodes is finer than an arrangement pitch of the drive electrodes, the drive electrodes are configured to perform a touch detection in a first sensing period and in a second sensing period, and the subdivided electrodes are driven collectively in the first sensing period and driven individually in the second sensing period.
