US Patent 10908719 Touch display device, touch driving circuit, and touch driving method

Disclosed are a touch display device, a touch driving circuit, and a touch driving method. A touch display device, a touch driving circuit, and a touch driving method is capable of supplying touch driving signals having different signal characteristics (e.g., driving frequencies) to touch electrodes or sensing groups by considering such touch electrode-specific or sensing group-specific difference. By this configuration, without reducing touch sensitivity, the touch sensing time required to sense all of the touch electrodes can be reduced, and a display driving time can be significantly lengthened, making it possible to implement a display requiring a large screen and high-resolution.
