Description of the Invention: [Technical Field] The present invention relates to a touch panel, and more particularly to a touch panel having an anti-missing function. [Prior Art] U.S. Patent No. 6,819, 316, "Flexible Capacitive Touch Sensor" has disclosed that electrical leads, electrodes, and conductive areas are set. In the outer peripheral area of the substrate, it is intended to maximize the active area. The capacitive touch sensor disclosed in U.S. Patent No. 6,819,316, contributes to the extent of the area of the active area. However, there are some problems in the application of touch panels to handheld products (such as mobile phones). The marginal area of the touch panel often has a misunderstanding situation. Therefore, it is invented by the people who have improved their minds. The panel prevents false detections that occur in the marginal area. SUMMARY OF THE INVENTION An object of the present invention is to provide a control panel capable of preventing occurrence of false detection sensing in a marginal region. In order to achieve the above object of the present invention, the present invention provides a touch panel having an anti-missing function, including a touch detector (t〇uch %黯), and a marginal region of the touch 200928904 sensor (outer per i) The phera 1 area is configured to connect at least one electrical lead to the touch sensor, wherein the conductive shielding layer is disposed at a position corresponding to the marginal region to prevent the user from being used. Error detection sensing caused by touches in the marginal area. The advantages and spirit of the present invention will be further understood from the following detailed description of the invention. [Embodiment] The first figure shows a structural exploded view of a touch panel having an anti-missing function according to the present invention, and the second A shows a schematic structural view of a touch sensor used in the touch panel of the present invention, and a second B The figure shows a schematic structural view of another touch sensor used in the touch panel of the present invention. The touch panel 1 with the anti-missing function of the present invention includes: a touch sensor 10 and a conductive shielding layer 11 , and the shielding layer 11 covers the touch sensor 1 Out Outer peripheral area 10b. In the first figure, the area marked with a slash is the marginal area1. The touch sensor 1 can directly use a conventional touch sensor, such as a touch sensor of US6, 819, 316, or a projected capacitive touch sensor (Projected capacitive touch sensor). ° See Figure 2A, since the touch sensor i is to maximize the area of the active area 10a, so the electrical leads 101 and the electrodes 103 are placed. Marginal area i〇b 200928904 Nakata - Object, such as a finger, after touching the active area 1', the touch sensor 1 can immediately detect the touch position, and the transmission should touch The two-dimensional coordinate signal of the touch position. Since the marginal area jump is provided with the running line ιοί and the electrode 103, and the running line 1〇1 and the electrode 1〇3 are electrically connected to the active area IGa, when the user touches the marginal position of the touch control surface, It may also be judged that the touch panel is touched. However, the marginal area (10) does not belong to the range of the active area l〇a, therefore, the touch in the marginal area will cause the wrong touch gamma induction. The main function of the conductive shielding layer 11 of the present invention is to prevent the above-mentioned false detection sensing from occurring on the touch surface control. See the second B ® , the projected capacitive touch detector 1 () in the active area l 〇 a includes the X-axis and γ (10) sensing unit for measuring the touch position. The electrical line (Electrical ieads) l〇1 is located in the marginal area 1〇b. One end of the running line 101 is used to connect the sensing unit in the active area, and the other end is connected to the control chip (not shown). Under normal circumstances, the user's finger operates in the active area 10a. However, when the user touches the marginal position of the touch surface control 1, for example, when the boundary position between the marginal area 1〇b and the active area 1〇a is touched, the touch position at this time does not belong to the active area l〇a. The range, but touch panel 1 may still be inductive. The main function of the conductive shielding layer u of the present invention is to prevent the above-mentioned errors from occurring in the touch panel control 1. The second figure shows a cross-sectional view of the touch panel of the present invention with the anti-missing function 7 200928904 along the cross-sectional line 3_3 of the first figure. The conductive shielding layer u is disposed on the surface of the marginal region lb of the touch sensor 10. In the case of the second A diagram, the shielding layer 11 can be used to shield the running line 101 and the electrode 103 located in the marginal region 10b. If the arrangement shape of the running line 1〇1 and the electrode 1〇3 arranged in the marginal area i〇b is a mouth shape, the shielding layer 11 adopts a square-shaped structure corresponding to the arrangement position of the running line 101 and the electrode 103. On the other hand, if the arrangement shape of the running line 1〇1 and the electrode 1〇3 arranged in the marginal region 10b is a gate shape, the 〇 shielding layer 11 adopts a gate-shaped structure corresponding to the arrangement position of the running line 101 and the electrode 103. . In the case of the second B diagram, the shielding layer 丨丨 can be used to shield the running line 1〇1′ located in the marginal region 10b, and even further obscuring a portion located at the boundary between the active area 1〇& and the marginal area 10b. Array electrode. In the second figure, the specific implementation of the shielding layer 11 can be applied to the surface of the marginal region 1〇b using a conductive coating (for example, a conductive ink); or a conductive tape or a metal sheet or metal. A mesh or the like places G on the surface of the marginal area hall; or a thin layer of indium tin oxide (ITO) transparent conductive coating is formed on the surface of the marginal region 1〇b. The fourth figure provides another embodiment of the present invention. The conductive shielding layer u is located at the marginal region of the inner surface of the machine 4, and the marginal region of the shim surface of the casing 4 corresponds to the marginal region 10b of the touch sensor 10. Referring to the fifth figure, the mobile phone 5 using the touch panel with the anti-missing function of the present invention is exemplified as 200928904, and the casing 4 is the casing of the mobile phone 5 The conductive shielding layer 11 in the casing 4 is located on the inner surface of the casing 4 and corresponds to the marginal region lb of the touch sensor 10. In the fifth figure, the area marked with oblique lines is printed at the position of the conductive shielding layer 11 at the inner surface of the casing 4. In the fourth figure, the specific implementation of the masking layer 11 can be applied to the marginal region of the inner surface of the casing 4 by using a conductive paint such as a conductive ink. Alternatively, a conductive tape or a metal piece or a metal mesh is attached to the marginal area of the inner surface of the casing 4. In the case of the second A picture, if the arrangement of the running line and the electrode 1G3 arranged in the marginal area 1〇b is a mouth shape, the shielding layer 11 located on the inner surface of the casing 4 corresponds to the marginal area l〇b. 101 and the mouth shape layout of the electrode 1〇3. On the other hand, if the arrangement of the running line 1〇1 and the electrode 103 arranged in the marginal area 1〇b is a door? In the shape, the shielding layer 11 on the inner surface of the casing 4 adopts a gate-shaped layout corresponding to the running line 101 and the electrodes 1〇3. Similarly, in the case of the second B diagram, the shape of the shielding layer 11 on the inner surface of the casing 4 corresponds to the layout of the running line 101, and even the shielding layer 11 located on the inner surface of the casing 4 is further shielded. A part of the sensing unit of the intersection of 10 a and the marginal region 10b. According to the fourth embodiment of the present invention, the shielding layer u is disposed in a marginal region corresponding to the touch sensor 10, and the conductive shielding layer 11 is located in the touch sensor 11 and the chassis 4. between. 200928904 The shielding layer 11 in the third and fourth figures can be further connected with the ground potential to enhance the shielding effect.
