Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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 s…
