Many consumer electronic products, such as mobile phones and computer screens, have increased the operation control of touch panels. Touch panels have become popular. And fast-growing applications and markets. From the technical principle to distinguish the touch panel' can be divided into five basic types: pressure sensing touch panel, infrared touch panel, surface acoustic wave touch panel, resistive touch panel, capacitive touch panel . Among them, the pressure sensing type touch panel has withdrawn from the market; although the price of the infrared type touch panel is low, the outer frame is easily damaged, and the light interference is generated, which is easy to be distorted on the curved surface; the surface acoustic wave type touch panel screen is relatively clear and has a clear The anti-riot effect is 'suitable for all occasions' but the main disadvantage is that the surface of the panel - if there are water droplets or dust - will make the panel reaction dull or even not working; the resistive touch panel has lower positioning accuracy and higher price The design theory of the surface-controlled capacitive touch panel is good, but the image distortion is difficult to be fundamentally solved. 1 is a schematic diagram of a resistive touch panel of the prior art; The upper substrate n of the resistive touch panel 1 is covered with an oxygen indium tin layer (ITO) 13 and is made of a polypolymer (PET) film material. Further, the lower substrate 12 is covered with an oxidized samarium oxide layer 14, and 201005597...a/n is made of PET or a glass material. The upper and lower substrates u and 12 are separated by a granular insulator 15 (Spacer Dot) 15 . 2 is a schematic view showing the touch of the resistive touch panel shown in FIG. 1 . The X-axis and Y-axis of the resistive touch panel are each driven by a voltage of 〇~5V. When the resistive touch panel is pressed, the indium tin oxide layers of the upper and lower substrates at the contact point position are in contact with each other', so that the loop is turned on, and a voltage drop is generated. At this point, the controller will calculate the proportion of the voltage drop and then further out of the coordinate axis. The rate of this touch method is low, and the response time of the touch processing signal is slow, which is unfavorable for multi-touch. FIG. 3 is a schematic exploded view of another conventional capacitive touch panel. The capacitive touch panel 2 shown in FIG. 3 includes a glass substrate 24, a first conductive cover layer 25 disposed on the lower side of the glass substrate 24, and a second conductive cover layer 23 disposed on the glass substrate 24 (the material of which is usually IT〇), an electrode pattern layer 22 disposed on the second conductive cover layer 23, and a hard protective cover layer 21 disposed on the electrode pattern layer 22. FIG. 4 is a schematic diagram of the touch of the capacitive touch panel shown in FIG. 3. The structure of the electric touch panel 2 is relatively simple, and is basically based on the second conductive cover layer 23 (ITO). That is, the four corners of the second conductive cap layer 23 (IT〇) are discharged to form a uniform electric field on the surface. When an electrically conductive object, such as a human finger, touches the panel and draws a small amount of current, the latter controller calculates the ratio at which the current is drawn and calculates the position coordinates of the touch point. Although the capacitive touch panel design theory is good, the image distortion is difficult to be fundamentally solved. Due to various defects and problems in the touch panel of the prior art, the application of the touch panel is a simple and accurate positioning of the touch panel due to the 6 25914 twf.doc/n 201005597w --------w The last important question.

After the remaining panel is pressed, the electrode layer 413 on the first substrate 41 of the contact portion 450 is electrically contacted with the first extension electrode portion 4121 and the second extension electrode 422 on the second substrate 42 to enable scanning. The electric signal ζ in the electrode line 422 is transmitted to the electrode layer 413 on the first substrate through the contact window opening 425 and the second extension electrode portion 4221, and is further transmitted from the electrode layer 413 to the first extension electrode portion 4121 and the detecting electrode. Line 412. Thereafter, the other end of the detection electrode line 412 is detected to confirm whether there is a shunt signal Iy from the electric signal, and the other end of the scan electrode line 422 is detected to have a decrease in the electric signal due to shunting. That is, the shunt lx is detected to determine the position of the touch point 45. In the case of Q, only the detecting electrode line 412 and the scanning electrode line 422 at the corresponding pressing point 450 can detect the shunt signals Iy and Ιχ, respectively. And the detection of electricity at non-touching points Line 412 does not detect the shunt signal, and the scan signal line 422 at the non-touch point will detect the complete electrical signal j. This is because the first extended electrode portion 4121 and the touch point at the touch point 450 The second extension electrode portion 4221 corresponding to 450 passes through the electrode layer 413 under pressure to form an electrical connection, so the first 12 201005597 25914 twf.doc/n extended electrode portion 4121 and the second extension corresponding to the contact point 45 〇 The electrode portion 4221 can be turned on. The current is shunted from the scan electrode 422 via the second extended electrode portion 4221 at the touch point 450, and the first extended electrode portion 4121 is shunted to the detecting electrode 412' corresponding to the touch point 450 by the scanning electrode 422. The end of the signal detecting the reduced current value lx and the detected electrode 412 detecting the shunted electrical signal Iy can locate the position coordinate of the touch point 450. In addition, in the above-mentioned electrical signal detecting step 'If the electrical signal Iy in the detecting electrode is not detected, the writing of the electrical signal I' is repeated and the steps of detecting the shunt signal Iy and the electric signal reduction (split signal lx) are repeatedly repeated. The above touch panel can be combined with the display panel. Constitute a flat The display device 804 is disposed on the display panel 804, and the touch panel 802 is electrically connected to the display panel 804. The display panel 804 can be a liquid crystal display panel. The touch panel 8〇2 can be The touch panel of any of the foregoing embodiments is similar to the manufacturing process of the liquid crystal display panel and has a simple structure, so it is suitable for the TFT-LCD factory to be put into manufacture. The touch panel has the advantages of simple structure, convenient detection and accurate positioning, and thus overcomes various defects and problems of the touch panel in the prior art. The present invention has been described in its preferred embodiments, and is not intended to limit the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention. The scope of protection is subject to the definition of the scope of the patent application. [Simple diagram description] 13 W 25914twf.doc/n 201005597
