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.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2014-0185809 filed on December 22, 2014 and Korean Patent Application No. 10-2015-0136677 filed on September 25, 2015 for all purposes These patent applications are hereby incorporated by reference as if fully set forth herein. technical field [0002] The invention relates to a touch sensing device, a touch sensing circuit, a data driving circuit and a display device driving method. Background technique [0003] Recently, a touch sensor provided on a display panel having a touch function can realize various user interfaces (UI). A display panel including a touch sensor is an input / output tool capable of both a touch-based input function and an information output function. [0004] The advantages of display panels with capacitive touch functionality are that they have better durability and sharpness and are capable of multi-touch recognition and proximity compared to existing resistive touch pane...
