The axis sensing line detects whether the capacitance node changes in the capacitance value. Therefore, when the human finger is input on the surface of the touch panel, the human body and the touch panel are in the same environment, and the human body is also good. The conductor, so the human body will also be affected by the electromagnetic noise of the surrounding environment. In this situation, when the human finger touches the surface of the touch panel to perform a touch operation, the human finger not only has its own finger electric form number A0101, page 3/22 pages, M429926, and touches the touch. The panel is inductively generated by a corresponding touch signal. The human finger is also affected by electromagnetic noise in the surrounding environment to generate a noise capacitor, and when the finger is in contact with the surface of the touch panel. At the same time, a change in capacitance occurs at the capacitor node near the contact position, so the pulse signal detected on each capacitor node will be affected by the noise of the noise capacitor, especially when the surrounding environment is electromagnetic. When the noise capacitance of the noise is much larger than the finger capacitance, the pulse signal generated by the finger capacitance is not easily detected and recognized, which causes the sensitivity of the touch panel to be poor. [New content] [0003] In order to effectively overcome the above-mentioned problems of the prior art, the present invention improves the touch panel by means of detecting electromagnetic noise to filter out the touch signal, thereby improving the recognition of the touch signal, thereby improving the touch panel.

As a microcontroller to compare the first-electromagnetic noise signal mixed in the touch signal. The insulating layer 360 is selected from an insulating material to be coated on the wire layer and the sensing element 350 by coating or screen printing to protect the wire 365 line or the sensing element 35 from being damaged by external objects. 〇 / / / 22 pages of the form number A0101 at the side of the insulating layer 306 is provided with a slot 3 6 2 'slot hole 3 6 2 inside • 4 note has - conductive win 364, making a flexible circuit board The 370 can be electrically connected to the wire layer 340 or the sensing element 350 by being fixed on the slot 362 by the conductive adhesive 364. Referring to Fig. 8, there is shown a cross-sectional view of a fourth embodiment of the touch panel of the present invention. As shown in the figure, the fourth embodiment is different from the third embodiment in the position where the sensing element 350 is disposed. In the fourth embodiment, the sensing element 350 is mainly disposed on the transparent cover 310 and the shielding layer 330. The surface of the transparent cover 310 disposed on the periphery of the touch electrode layer 320 can also achieve the same effect of sensing and absorbing electromagnetic noise signals located around the operating environment of the touch panel 3. The remaining components and their corresponding functions and functions disposed in the touch panel 3 are similar to those of the third embodiment, and are not described herein again. As can be seen from the above, the present invention mainly integrates the sensing component into the structure of the touch panel, so that when the touch panel performs a touch operation on the touch module during the operation of the touch panel, the touch is The module can generate a corresponding touch signal input to the operation processing module, and during the touch operation of the conductive object, the electromagnetic noise signal sensed by the conductive object around the touch panel operating environment is also in the touch operation. In the process, the corresponding first electromagnetic noise signal is generated and mixed in the touch signal, and the sensing element is used to detect and contact the conductive object during the touch operation of the conductive object. The second electromagnetic noise signal around the same operating environment of the control panel transmits the second electromagnetic noise signal to the detection module, so that the operation processing module compares the first electromagnetic noise signal in the touch signal After the first electromagnetic noise signal, the interference of the first electromagnetic noise signal is excluded to resolve and separate the correct touch form number Α0101 page 11/22 page M429926 signal , 洚. and reach: enhance the recognition of the integrated touch signal, and ♦. At the same time improve the sensitivity of the touch operation of the touch panel. In summary, it is only a preferred embodiment of the present invention, and is not intended to limit the present invention; any equivalent modification or replacement that is not done in the spirit of the present disclosure should be included in the patent application described later.
