Abstract

The invention provides a touch control display panel which includes 2N touch control reading lines, 2N sensing units, a touch control induction line, multiple pixels and 2N data lines. a distance between each data line and a corresponding touch control reading line is a first preset value. N data lines of the 2N data lines are used for providing positive-electrode data voltages, and the rest N data lines are used for providing negative-electrode data voltages.

Description

technical field [0001] The present invention relates to a touch display panel and a driving method thereof, in particular to a touch display panel with data lines and a driving method thereof. Background technique [0002] In recent years, the touch display panel has become a popular product. Using the touch display panel as a user operation interface allows users to directly operate electronic products through touch mode instead of keyboard or mouse. The touch display panel will locate the position touched by the user through signal processing according to the change of the sensing signal corresponding to the touch sensing unit. [0003] Please refer to figure 1 . figure 1 It is a schematic diagram of the sensing unit 100 of the photosensitive touch display panel. The sensing unit 100 includes a photosensitive thin film transistor (photo TFT) 102 , a touch readout thin film transistor (readout TFT) 104 and a capacitor C. The photosensitive thin film transistor 102 will ...
