Abstract:
1. A touch tactile display apparatus, comprising: a display panel configured to display an image in a frame section; and a tactile touch portion configured to sense a touch by a user and provide an electro-tactile feeling to an area in which the touch is sensed, wherein the tactile touch portion comprises: drive electrodes spaced apart from each other; sensing electrodes spaced apart from the drive electrodes, wherein capacitors are formed between the sensing electrodes and each of their adjacent drive electrodes; a touch processor configured to sense an amount of change of capacitance of the capacitors to obtain a touch coordinate; and a tactile processor configured to receive the touch coordinate from the touch processor, provide a first tactile signal to a drive electrode corresponding to the touch coordinate and provide a second tactile signal different from the first tactile signal to the rest of the drive electrodes and the sensing electrodes while the first tactile signal is being provided, wherein the rest of the drive electrodes do not correspond to a touch coordinate.
