The first input terminal of the delay unit is connected to corresponding previous gate driver, the first output terminal of the delay unit is connected to corresponding subsequent gate driver. The delay unit outputs a starting signal to the subsequent gate driver for enabling it after a predetermined time elapses since the previous gate driver outputs a driving signal. The delay unit achieves shift registering between the previous gate driver and the subsequent gate driver, to form a touch-control time period after the previous gate driver outputs a driving signal and before the subsequent gate driver is enabled, so as to ensure that the touch display panel can also achieve a touch-control function with high precision on the premise of achieving a display function of high resolution.

摘要： The present invention discloses a touch display panel, a detecting method thereof, and a display device. The common electrode layer is divided into a plurality of independent self capacitance electrodes, and the common electrode is multiplexed as self capacitance electrodes. There is no need to provide an additional film, and it is only required to modify the pattern of the common electrode layer in the current LCD panel. Thus, the production cost is reduced, and the production efficiency is improved. Since the self capacitance electrodes are formed by dividing the common electrode layer in the above-mentioned touch display panel, a compensating electrode is further provided which is arranged in a layer different from that of the self capacitance electrodes, is insulated from the self capacitance electrodes, and at least covers a portion of a partition gap between neighboring self capacitance electrodes. A common electrode signal is applied to the compensating electrode during a display period. In this way, the common electrode signal which is applied to the compensating electrode during display can compensate the common electrode signal at partition gaps of the self capacitance, thus ensuring that liquid crystal molecules at partition gaps normally invert and that the overall display panel displays normally.
