Touchscreen display device, touch driving circuit, and driving method

Last updated:

Abstract:

Provided are a touchscreen display device, a touch driving circuit, and a driving method. Image display and touch sensing are simultaneously performed and the interference between display driving and touch driving are minimized or removed, so that excellent image display and touch sensing performance is obtained. Poor touch sensitivity occurring in a specific area (e.g. an edge area) is reduced by using differential sensing sequence control, internal correction resistors of the touch driving circuit, and signal characteristics control.
