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 design for a scan driver and a display device including the scan driver that is more resilient to electrostatic discharge. Thin film transistors within a stage are designed differently depending on whether or not a gate of the transistor is connected to an external source. Transistors whose gate is connected to an external source is specially designed to withstand electrostatic discharge applied to the gate thereof by one or more of increasing a number of channel areas, decreasing a length of an ohmic bridge, including a resistive element to the gate, decreasing a width of a channel areas, and increasing a width of the active layer.

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.
