When the touch sensing device is in operation, the scan driving circuit 〇2 extracts the scanning signals and sequentially applies the scanning signals to the scanning lines G〇~Gff1, and when the kth scanning=receives the scanning signals, the touch display panel The thin film transistor 111 of the (9) pixel plug-in element in 11{) is turned on. At this time, the data driving circuit 13 = = data signal is respectively supplied to the said data line D 丨 D Dn and the thin 犋 transistor 1 f The first pixel unit is configured to cause the touch display panel 110U to display a corresponding screen. When the user applies a touch action to the dance touch display device by using a finger or a stylus pen or the like to perform a certain operation, the touch corresponding to the position protected by the touch action (hereinafter referred to as the touch position) The control sensing unit 119 receives an external force generated by the touch action, in which case the protrusion 121 in the sensing element 108 is caused by the external force so that the common electrode layer covering the surface thereof abuts to The touch electrode 22 is configured to apply a common voltage carried on the diagnostic common electrode layer to the switching element j, thereby causing the switching element to be turned on. When the scanning line Gi-1 connected to the touch sensing unit U9 receives the broom: number, the switching element 123 uses the scanning signal as the touch field form nickname A0101, U1, 25 pages. The nickname 098206453 201117180 is outputted to the signal processing unit 14 of the signal processing circuit (4) through the touch sensing line 114, and the timing control is such that the field scanning line Gi-i receives the scanning signal. The first control switch 142 is closed in the signal processing unit i4i, and the second controlled switch 143 is turned off. Therefore, the "Hui touch sensing signal is sent to the first signal storage unit 144 through the first controlled switch 143. The phase capacitor 147 carries out the wealth. Φ is affected by factors such as the parasitic components inside the touch display device and the external environment level, and the touch sensing signal received by the signal processing unit 141 may be interspersed with other interference signals. [0023] When the field-scanning line Gi receives the scanning signal, the first controlled switch 142 of the signal processing unit 141 is turned off, and the second controlled switch 143 is closed; at this time, the coupled sensing unit 1〇1 The coupling signal is outputted to the signal processing unit 141 by the coupling of the parasitic components inside the touch display device and the external environment temperature, and the coupling signal is further sent to the second through the first control switch 143. The storage capacitor 147 in the signal storage unit 145 is stored. Since the coupling sensing unit 1〇9 is disposed adjacent to the touch sensing unit 1.8, and the structures of the two are similar, the coupling signal is substantially the same as the interference signal mixed in the touch sensing signal. After the touch (4) should be spoofed and the _ 峨 细 is in the corresponding signal storage elements 144 and 145, the comparison circuit reads the touch from the first signal storage unit 144 and the second signal storage unit Μ The sensing signal and the coupling signal are compared, and the touch sensing signal is processed according to the coupling signal to filter the interference signal from the touch sensing signal. [0024] Further, the comparison circuit 146 can output the touch sensing signal processed by the signal processing unit 098137661 Form No. A0101, page 12/25 pages 0982064534-0 201117180 141 to the control circuit 150 for the The control circuit 150 determines the coordinates of the touch position. The control circuit 150 can learn the specific valley of the operation performed by the user according to the determined coordinates, and provide a corresponding control signal to control the touch display device or use. The electronic products of the touch display device operate accordingly. [0025] The touch display device provided by the above-mentioned embodiments of the present invention provides a structure in each touch sensing unit 119 of the touch display panel 110 at the same time. The touch sensing unit 丄〇8 and the coupling sensing unit 〇9 are similarly received, and the touch sensing signal outputted by the signal processing circuit 140 to the touch sensing unit 108 according to the coupling signal provided by the coupling sensing unit 109 The processing is performed to filter out the interference signal mixed in the touch sensing signal. Therefore, the control circuit 150 can accurately determine the position pointed by the touch action applied by the user, and control the touch display device according to the position or use the touch display device according to the processed touch sensing signal. The sub-product performs the corresponding operation, thereby reducing the probability of malfunction of the control display device and related electronic products, and improving the stability and reliability of the T-control device and related electronic products ' ^ ^ r δ - products. 4 and FIG. 5, FIG. 4 is a schematic structural diagram of another embodiment of the touch display device of the present invention, and FIG. 5 is a circuit structure of a signal processing unit in the signal processing circuit of the touch display device of FIG. schematic diagram. The touch display device 200 is similar to the touch display device 1 provided in the previous embodiment, but the difference between the two is different in the structure of the touch display panel. Specifically, in the touch display panel 21 of the touch display device 200, the touch sensing element 208 and the coupling sensor 098137661 of each touch sensing unit 219 are numbered Α0101, page 13 / 25 pages 0982064534- The elements 209 are respectively disposed in the same column of pixel units and are connected to the same scanning line Gi, and the touch sensing element 208 is connected to the signal processing circuit 240 through a first touch sensing line 214. The coupling sensing element 209 The signal processing circuit 240 is connected to the second touch sensing line 214. The first touch sensing line 214 is connected to the comparison circuit 246 through the first controlled switch 242 of the signal processing unit 241; the first touch sensing line 214 is connected to the comparison circuit through the second controlled switch 243 of the signal processing unit 241. [0027] With the above configuration, if the user applies a touch action to the touch display device 200, the touch sensing element 208 and the coupled sensing element are received when the scan line Gi receives the scan signal. The 209 can simultaneously provide the touch sensing signal and the coupling signal to the signal processing circuit, and the signal processing circuit can further process the touch sensing signal according to the coupling signal to filter out interference interposed in the touch sensing signal. The signal ensures the stability and reliability of the touch display device 200. [0028] However, the present invention may have other various modifications. For example, the touch sensing element may be composed of the protrusion 121, the touch electrode 122 and a switching element 123, which may be a photoelectric film transistor. The photosensitive touch sensing component is formed. When the switching component 123 and 125 are the top gate type thin film transistor with the gate in the uppermost layer, the touch sensing component 108 may not include the touch electrode 122. The sensing element 109 may not include the electrode 124, and the protrusion 121 is caused by the external force so that the common electrode layer covering the surface thereof abuts against the gate of the switching element 132. [0029] 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 098137661 Form No. A0101 Page 14 / Total 25 Page 0982064534-0 201117180, and the scope of the present invention is not limited to the above embodiments, and the skill of the present invention is familiar to the present invention.
