Japanese Patent JP5980157
Kind Code:
B2
Abstract:
According to an aspect, a display device with a touch detection function includes: a display region; a plurality of drive electrodes; a control device; a touch detection electrode that is opposed to the drive electrodes and forms capacitance with respect to the drive electrodes; power supply wiring arranged in a frame region positioned outside the display region; and a plurality of drive electrode scanning units that select the drive electrode to be coupled to the power supply wiring. When the drive electrode scanning unit simultaneously selects the drive electrodes of which number is equal to or larger than the number of pieces of the power supply wiring, the control device supplies a touch driving signal that is multiplexed based on a certain code to each of the selected drive electrodes.
