Description of the Invention: [Technical Field] The present invention relates to a touch panel and a display module, and more particularly to a capacitive touch panel and a display module. [Prior Art] In recent years, with the rapid development and wide application of information technology, wireless communication and information appliances, the operation interface of many information products has been changed from a traditional keyboard or mouse to a touch panel as an input device. Common touch panels can be roughly divided into capacitive touch panels and resistive touch panels. Capacitive touch panels are attracting attention because of their multi-touch characteristics. When the user approaches or touches the surface of the capacitive touch panel with a finger or a conductive object, the capacitance value on the capacitive touch panel changes correspondingly. The capacitive touch panel utilizes such a change in capacitance value to sense and calculate the touch position. It is a partial top view of a conventional touch panel. Referring to the contact area of the user's finger and the touch panel 100, only the sensing pad 112 is covered, and the adjacent sensing pad H4 is branched by the user's finger. It will be too small. At this time, it is difficult to perform the interpolation operation by using the ratio of the capacitance of the sense 塾 and the change of the capacitance of the sense pad 114, so that the fine contact area R1G (four) is not obtained. To solve the above problem, the solution is to reduce the area and spacing of the money measurement (including the feeling of ιΐ2 and the sensing 塾1M) to ensure that each movement of the manufacturer will lead to a large amount on the two reduction pads. Capacitance changes. _, reduction feeling 201124897 P090275ALZ1TW 33271twf.doc/n The spacing of the pads is also equal to the spacing between the sensing lines 11〇, which will eventually increase the number of sensing lines 110 while increasing the number of wafers connected to the sensing lines 11〇. As a result, the cost of the touch panel is increased. SUMMARY OF THE INVENTION The present invention provides a touch panel that solves the problem that positioning accuracy and low cost are difficult to balance. The present invention provides a display module that uses a touch panel with high positioning accuracy and low cost. The touch panel of the present invention comprises a substrate and a plurality of ^ sensors, a second sensor, a first connecting line, a second connecting line and an insulating pad disposed thereon. The edge of each of the first sensing ridges has a plurality of first projections. The edges of each of the second sensing pads have a plurality of second projections. Any of the first sensing pads surrounds the plurality of second sensing pads. A second projection adjacent to any of the first sensing ridges projects between the two first projections. The adjacent two tangent common tangents pass through a first bulge that protrudes between the two. Each of the '帛-connecting wires connects the two adjacent first sensing pads to the adjacent two second sensing pads. The insulating mat is disposed at the intersection of the second connecting wires to insulate the two. The remote control display module includes the aforementioned touch panel with the display transposed and not. In an embodiment of the convex-only touch panel and the display module, each of the first convex shapes is a rectangle, a triangle or a trapezoid. In an embodiment of the touch panel and the display module of the present invention, each of the two portions of the 201124897 ru^/DA^ZlTW 33271twf.d〇c/n is rectangular, triangular or trapezoidal.

The above features and advantages of the present invention are more apparent in the light of the following description of the present invention and are described in detail below with reference to the accompanying drawings. [Embodiment] FIG. 2 is a partial top view of a touch panel according to an embodiment of the present invention, and FIG. 3 is an enlarged view of a portion of the components of FIG. Referring to FIG. 2 and FIG. 3 , the touch panel 200 of the present embodiment includes a substrate 21 , a plurality of first sensing pads 220 disposed on the substrate 21 , a plurality of second sensing pads 230 , and a plurality of first The connection line 240, the plurality of second connection lines 250, and the plurality of insulating pads 260. The edge of each of the first sensing turns 220 has a plurality of first projections 222. The edge of each of the second sensing jaws has a plurality of second projections 232. A plurality of second sensing pads 230 surround each of the first sensing pads 220. Adjacent to the first sensing pad 220, a second protrusion 232 of the 201124897 P090275ALZ1TW 33271twf.doc/n protrudes between the two first protrusions 222. Moreover, the common tangent line T1 of the two adjacent second projections 232 passes through a first projection 222 projecting between the two second projections 232. In other words, the edge of each of the first sensing pads 220 is partially embedded at the edge of the adjacent second sensing pad 230. Each of the first connecting wires 24 is connected to two adjacent first sensing electrodes 220. Each of the second connecting lines 25{) connects the adjacent two second sensing pads 230. 4 is a cross-sectional view of the touch panel of FIG. 2 taken along line w. Referring to FIG. 2 and FIG. 4, each of the insulating pads 260 is disposed at an intersection of a first connecting line 24 and a second connecting line 250 to insulate the first connecting line 24 and the second connecting line 250 from each other. . For example, the first connecting line 24 is disposed on the substrate 210, the insulating pad 260 covers the first connecting line 24, and the second connecting line 250 is disposed on the insulating pad 260. 2 and FIG. 3 'In the touch panel 2 of the present embodiment, the first protrusion 222 of the edge of the first sensing pad 220 is embedded in the adjacent second sensing pad 230 Between the second projections 232 of the edge. Therefore, when the user's finger or the conductive object approaches the touch panel or touches the contact area R2 of FIG. 3, the area of the second sensing pad 23〇 located in the contact area R2〇 is larger, that is, The change in capacitance produced on the second sense 塾23〇 will be more pronounced. At this time, the ratio of the capacitance change of the sensing pad (10) and the ratio of the electric weight of the sensing 塾 230 can be turned on (4) to obtain a more accurate ten-point position of the contact region R20. Compared with the sensing pad whose edge is a simple smooth line, the area of the sensing 塾 and the area of the first sensing 塾 220 are the same as the area of the 201124897 P090275ALZ1TW 33271twf.doc/n of the second sensing pad 230. The shortest distance from the center point of the first sensing pad 220 to the edge of the second sensing pad 230 may be shorter than the shortest distance from the center point of the conventional sensing pad to the edge of the adjacent conventional sensing pad. Therefore, the area of the first sensing pad 220 and the area of the second sensing pad 23〇 of the present embodiment are not reduced, and the center point of the first sensing pad 220 to the center point of the second sensing pad 23〇 The distance will not be reduced, but the area of the second sensing pad 230 located in the contact area R2〇 can be increased, thereby improving the positioning accuracy of the touch point. Meanwhile, since the distance from the center point of the first sensing pad 220 to the center point of the second sensing pad 23〇 does not need to be reduced, it is not necessary to increase the wafer connected to the first pad 22 and the second sensing pad 230. The number of (cut) does not increase the cost of the touch panel 200. Referring to FIG. 2 again in May, in the embodiment, the first sensing pad 22 〇 and the first-, the wiring 240 constitute a plurality of first sensing lines UG, and the second sensing pads 22 〇 and the second connecting lines 25G are formed. The second sensing line L2Q. Each of the first sense 2 UG is configured along the -th direction mQ, each second sense line u
