Abstract: A display device includes a display unit including pixels. A sensor unit overlaps with the display unit and includes sensors. A sensor driver transmits a driving signal to the sensors, and receives sensing signals corresponding to the driving signal from the sensors. One sensing period includes a first sensing period and a second sensing period. The sensor driver transmits a first driving signal having a first frequency to the sensors in the first sensing period, and transmits a second driving signal having a second frequency different from the first frequency to the sensors in the second sensing period.

Abstract: A display device includes a touch sensor, a touch driver, and display driver. The touch driver drives the touch sensor at a first frequency, provides touch driving signals to touch electrodes during a touch sensing period of a touch frame period, and stops providing the touch driving signals during a touch waiting period of the touch frame period. The display drivers drives a display panel at a second frequency lower than the first frequency in a first mode, provides scan signals to pixels during a display period of a display frame period, and stops providing the scan signals during a display waiting period of the display frame period. When the display driver switches from the first mode to a second mode, the display driver drives the display at a third frequency lower than the second frequency, and the touch driver increases the touch waiting period of the touch frame period.

Abstract: A display device is described including a display panel for displaying an image and an input sensing unit disposed on the display panel for sensing a user input. The input sensing unit includes: an electrode unit including first electrodes and second electrodes which intersect each other and a control unit for determining the proximity of an object or the shape of the object, based on capacitance change values of the first electrodes and the second electrodes. In a first mode the input sensing unit is driven using a self-capacitance method. The control unit may merge the capacitance change values, and determine the proximity of the object based on the merged value. In a second mode based on mutual capacitance, the control unit may determine the shape of the object.

Abstract: A touch detection module includes driving electrodes extending parallel to each other, sensing electrodes crossing the driving electrodes, and a touch driver circuit for supplying touch driving signals to the driving electrodes and for detecting touch sensing signals through the sensing electrodes to determine touch position coordinates. The touch driver circuit selects between a group driving scheme and a sequential driving scheme for at least one frame. According to the group driving scheme, the touch driver circuit sorts the driving electrodes into groups, simultaneously drives driving electrodes in a same group among the groups, and drives the groups at different times. According to the sequential driving scheme, the touch driving circuit sequentially drives the driving electrodes.
