Problems solved by technology
Regardless of whether the second axial electrode 140Y or the bridging line 110 is disposed on the insulating block 120 , it is possible that the second axial electrode 140Y on the insulating block 120 may be damaged due to the topographic relief caused by the insulating block 120 and its edge condition. Or the problem that the bridge line 110 breaks, which has a bad influence on the signal stability of the touch panel 100

The invention provides a touch panel comprising an insulating layer, first axial electrodes and second axial electrodes. The insulating layer is provided with a plurality of first holes and a plurality of second holes. Each of the first axial electrodes comprises a plurality of first upper conductive units and a plurality of first lower conductive units which are arranged on the upper side and the lower side of the insulating layer respectively. The first holes correspond to the first lower conductive units in an exposed manner, so that the first upper conductive units can be electrically connected with the first lower conductive units via the first holes. Each of the second axial electrodes comprises a plurality of second upper conductive units and a plurality of second lower conductive units which are arranged on the upper side and the lower side of the insulating layer respectively. The second holes correspond to the second lower conductive units in an exposed manner, so that the second upper conductive units can be electrically connected with the second lower conductive units via the second holes. The invention further provides a manufacturing method of the touch panel. Relative problems resulted from adoption of a design of bridge connection structure are solved, and quality and degree of reliability of products are improved.
Description
technical field [0001] The invention relates to an input interface and a manufacturing method thereof, in particular to a touch panel and a manufacturing method thereof. Background technique [0002] Touch panels have been widely used in many consumer electronic products in recent years. At present, the development of touch panel technology is very diverse. The more common technologies in portable small electronic devices include resistive and capacitive, etc. The operating principle uses sensing electrodes to detect changes in voltage or current at the touch point. And use the connecting wires connecting the sensing electrodes on the axes in different directions to send the signal back to complete the positioning. [0003] In the conventional capacitive touch panel technology, it is generally necessary to separate the sensing electrodes of different directions by a plurality of insulating blocks at the intersection of the connecting lines of different directions to prevent...
