Abstract
A touch detecting function display apparatus includes a plurality of common driving electrodes, a display element performing display, a touch detection element detecting an external approaching object, and a scanning driving unit performing first scanning driving for sequentially applying a display driving signal to the plurality of common driving electrodes in a time division manner and second scanning driving for sequentially applying a touch detection driving signal to the plurality of common driving electrodes in a time division manner, wherein the scanning driving unit performs the second scanning driving at a scanning speed higher than that of the first scanning driving, and applies the display driving signal to an overlapping common driving electrode when the common driving electrode selected as a target of the first scanning driving overlaps with the common driving electrode selected as a target of the second scanning driving.
