Abstract

The invention discloses a touch display apparatus and a driving method thereof. The driving method comprises the steps of applying a common voltage signal to each first touch electrode and applying a display signal to each data line during a display period; and applying a touch scanning signal to each first touch electrode during a touch detection period, wherein at least one part of the touch detection period is set in a display intermittent period, and the display intermittent period comprises a field blanking stage between adjacent frame cycles and a line blanking stage in a conduction interval of two adjacent scanning lines. According to the scheme provided by the apparatus and the method, the at least one part of the touch detection period is set in the display intermittent period, so that normal display time needed to be occupied for touch detection is shortened, the number of H-lines is reduced, and the display effect is improved.

Description

technical field [0001] The present disclosure generally relates to the field of display technology, and in particular, to a touch display device and a driving method thereof. Background technique [0002] The touch display device can detect the coordinate position of the finger on the touch display device through the touch electrodes, and perform corresponding operation instructions according to the coordinate position. [0003] In the current touch display device, the touch function is usually realized by two touch electrode layers, wherein each touch electrode layer has multiple touch electrodes arranged in parallel with each other, and the touch electrodes in the two touch electrode layers The extension directions intersect. Apply a touch scanning signal to each touch electrode on one of the touch electrode layers. When a human finger touches the screen of the touch display device, the finger forms a coupling capacitance with some touch electrodes on the screen, and from...
