Touch display device and touch driving circuit
Abstract:
A touch display device and a touch driving circuit are configured to drive at least one of the plurality of first touch electrode lines disposed in a first area with a first touch driving signal having a first touch driving frequency, and drive at least one of the plurality of second touch electrode lines disposed in a second area with a second touch driving signal having a second touch driving frequency that is different from the first touch driving frequency. Each of the first touch driving frequency and the second touch driving frequency is different from a display driving frequency related to display driving. to the touch display device reduces the influence of noise, increases the signal-to-noise ratio, and reduces the influence of driving the display, thereby improving the touch sensitivity.
