Abstract: A liquid crystal display panel, a display device, and a driving method thereof are disclosed. The liquid crystal display panel comprises a plurality of data line pairs, a plurality of scanning lines, and a pixel unit array, wherein the first scanning line and the second scanning line turn on TFT switches of two rows of pixel units simultaneously according to a scanning driving signal, and the first data line and the second data line charge the pixel electrodes of two rows of pixel units through the TFT switches according to a data driving signal.

Abstract: A touch display device, a controlling method, and a circuit thereof are disclosed. During a touch stage, under the control of a control circuit, the TFTs of the touch display device are all turned off, and a same control signal is provided to the data line and the common electrode. The data line and the common electrode always have a same electric potential during the touch stage, and thus the parasite capacitor that is formed by the data line and the common electrode cannot be charged. According to the present disclosure, the influence of the aforesaid parasite capacitor on the touch detection signal can be avoided effectively, and thus the accuracy of the touch detection can be improved.
