    Abstract: A display device includes a display panel and a touch panel. The touch panel calculates coordinate information of an input position by an electrostatic capacitive method in a first mode and calculates the coordinate information of the input position by an electromagnetic induction method in a second mode. The touch panel includes scan line groups and source line groups, which are operated as touch electrodes or touch coils on the basis of the operating mode thereof. In addition, the touch panel includes touch electrodes and touch coils, which are individually operated on the basis of the operating mode thereof.

    Abstract: A touch-sensitive display device is provided. The touch-sensitive display device includes a display panel and a touch panel. The display panel includes first and second substrates facing each other. The display panel is configured to display images through the second substrate. The touch panel is disposed on the second substrate and is configured to detect a touch event. The touch panel includes sensing electrodes spaced apart from each other, a conductive layer, and a touch processor. The conductive layer is electrically separated from the sensing electrodes. The touch processor is configured to provide sensing signals to the sensing electrodes and to obtain touch coordinates to which the touch event is input based on delay values of the sensing signals.

    Abstract: A touch tactile display apparatus includes a display panel and a tactile touch portion. The tactile touch portion is configured to sense a touch by a user and provide an electro-tactile feeling to an area in which the touch is sensed. The tactile touch portion includes a first electrode, a touch processor and a tactile processor. The touch processor applies a first signal to the first electrode to extract a touch coordinate. The tactile processor applies a second signal different from the first signal to the first electrode to provide the electro-tactile feeling. The first signal and the second signal are applied at different times.
