As can be seen from Fig. 3, the polarity of the data voltage signal received by the pixel unit 180 in two adjacent frames is opposite. Specifically, in the process of displaying the second frame picture, the pixel unit 180 receives a scan signal of a high level Vgh, and the data driving circuit 130 starts to provide the data signal to the pixel unit 18 The internal liquid crystal capacitor 185 is charged, so that the voltage of the liquid crystal capacitor 185 gradually increases until the scan signal is switched from the high level Vgh to the low level Vgl. When the scanning signal is switched from a high level to a low level, the voltage of the liquid crystal capacitor 185 will reach a maximum value Vm, after which it begins to decrease until it is stable to correspond to the data signal provided by the data driving circuit 130. Stable | Vs. Thereafter, in the Nth frame picture, the pixel unit 18 displays a gray level corresponding to the stable value Vs. The voltage difference between the maximum value Vm and the stable value Vs is the pixel unit 18〇 The feed-through voltage value vy is found by analysis to satisfy the following relationship with the liquid crystal capacitor 185 of the pixel unit 180 (formula A):

Also, (Vgh-Vgl) is the voltage difference between the high level and the low level of the scan signal, which is usually a fixed value. In the touch display device 100 provided by the present embodiment, the first, second, and third pictures 098137694 in the touch display unit 1 90 of the touch display panel 110 form number A0101 page 11 / total 20 pages 0982064617 -0 201117067 The capacitance ratio of the storage capacitor 186 and the compensation capacitor 187 of the prime unit are respectively equal to the area ratio of the pixel electrodes 182 of the first, second, and third pixel units, wherein the first, second, and third 昼The area ratio of the pixel electrodes 182 of the prime unit is the capacitance ratio of the liquid crystal capacitors 185 of the first, second, and third pixel units. Therefore, according to the above formula A, the same touch display unit 190 can be obtained. The feedthrough voltage value Vp generated by the respective pixel units during operation is substantially the same, thereby effectively reducing the flickering phenomenon of the touch display device 100 and improving the display quality of the touch display device 100. [0027] However, the present invention can also be modified in various other ways. For example, the above-mentioned gate-to-source overlap capacitor of the thin film transistor 111 is only an optional implementation of the present invention. In an embodiment, the compensation capacitor 187 may also be formed by other overlapping capacitors in the pixel unit 180. For example, the scan line 150 may further have a plurality of extension electrodes, and each extension electrode extends to a corresponding pixel unit. The inside of 180 and its pixel electrodes 182 overlap each other to form an overlap capacitor as the compensation capacitor 187. In still another alternative embodiment, the compensation capacitor 187 can also be a thin film capacitor specially fabricated between the scan line 150 and the pixel electrode 182. [0028] In addition, in another variant embodiment, only the capacitance ratio of the storage capacitor 186 of the first, second, and third pixel units in each pixel unit group may be set equal to three pixels. The area ratio of the electrodes 182, or only the capacitance ratio of the compensation capacitors 187 of the first, second, and third pixel units inside each pixel unit group is set equal to the area ratio of the three pixel electrodes 182. Therefore, in the working process of the touch display panel 110, 098137694, Form No. A0101, Page 12/20 pages 0982064617-0 201117067, the value of the feedthrough voltage generated by each pixel unit of the same pixel unit group does not differ. Therefore, the flickering phenomenon of the touch display panel 110 is reduced, and the display quality of the kneading surface is improved. [0030] In addition, in the preferred embodiment of the present invention, the common capacitor 170 extends from the storage capacitor electrode 184 and the pixel. The overlapping capacitance between the electrodes 182 is used as the storage capacitor 186. However, in an alternative embodiment, a storage capacitor electrode may be extended from the scan line 150, and the storage capacitor electrode of the scan line 150 and the pixel electrode 182 The overlapping capacitors serve as storage capacitors. In summary, the present invention has indeed met the requirements of the invention patent, and the patent application is filed according to law. However, the above description is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and those skilled in the art will be able to make equivalent modifications or variations in accordance with the spirit of the present invention.
