Description of the Invention: [Technical Field] The present invention relates to a sensor for a touch panel, particularly an electrode pattern formed at an edge of a touch panel. [Prior Art] Known touch panels can be classified into four types: resistive, capacitive, sonic, and optical. Its towel-type hard-to-finish panel is currently the cheapest and widely used on the market, but the capacitor-picked panel is gaining more attention and adoption. • The resistive touch panel is mainly composed of two sets of upper and lower IT〇 conductive layers. When using, the c-force is used to turn on the upper and lower electrodes. (4) Controlling the panel voltage change and calculating the contact point position to obtain the input position signal. 'Example: The published US patent Ν. · 4, you, milk technology is commonly used in EloTouch's 5-wire resistive touch panel. The capacitive touch panel forms a conductive layer (such as a oxidized metal layer) on the glass substrate, and then the watchmaker becomes the f-lake case. The principle of the silk layer covering the surface is provided by the four corners of the camp. Voltage, and then borrowed _ surface formed - electric field, when the finger touches the screen will make the electric field different electricity, you can calculate two: test, according to the current from the four corners of the proportion of not JP. Ten different hand press positions. For example, 4,198,539 > 4,293 734 > 4 ^7i . 1Να , , 371,746 and 6,781,579 disclose the technology of the touch panel. In the electric valley, the touch panel has evaluation indexes of three-sided keys, including = electrode construction complexity, and electricity is proportional to manufacturing cost, electrode pattern touch === complexity is the width of the case Will directly affect the touch screen can be considered == column formed transparent electricity suspects · 3 eight ^ ff) simple, by the Wei Wei Road staggered the number of rows and the distribution position is more gradual change 200919289 Γ control: Γ charge The distribution density also becomes a more gradual change, and vice versa is the linearity of the electric field of the smrrr close to the frame area. On the other hand, due to the Thunder, and the intersection of 1^ ', the four corners of the conductive silver road can be effectively improved. The resistance value, the lower the value of the fuser's operation, the lower the mosquito value is too low __ is not conducive to the touch panel control and shouting =! ° How to improve the electric field of the touch panel, reduce the complexity of the electric test case = And reducing the width of the electrode ugly, is to improve the panel design and manufacturer = [Summary] f- The object of the present invention is to provide an electrode pattern capable of forming a self-heating electric field. To achieve the above objective, the capacitive touch panel disclosed in the present invention includes a conductive layer formed on the surface of the insulating substrate, and an electrode formed on the surface of the conductive layer and disposed at the edge of the panel. The pattern, the electrode pattern comprises a plurality of rows of conductive silver t, and the conductive silver circuit has a plurality of electrodes which are equally spaced and equally spaced; & The manner in which the two adjacent silver circuits are positioned relative to each other causes the linearity of the electric field to be improved. Another object of the present invention is to reduce the width of the electrode, so that the touch panel can be used to increase the usable range of the touch screen and the assembly space of the touch screen. </ RTI> </ RTI> </ RTI> </ RTI> </ RTI> </ RTI> </ RTI> </ RTI> </ RTI> </ RTI> </ RTI> [Embodiment] First, please refer to "Figure 1".
