Abstract:
The present disclosure provides a touch sensing device, a touch sensing circuit, a data driving circuit, and a display device driving method, which make it possible to activate different sensing areas according to a finger mode and a hover mode, and which activate as many sensing areas as possible simultaneously in a hover mode, which means sensing driving in the case of non-contact with regard to sensing areas, thereby enhancing sensing sensitivity, and improving sensing detection performance even in the hover mode.
