Problems solved by technology
Since the electrical insulation layer at the location of the bridging structure has a height, the jumper must cross the height of the electrical insulation layer to electrically connect the electrodes in the same direction when the jumper is formed, so the jumper has "climbing" on both sides of the electrical insulation layer. Due to the fragile physical properties of ITO, it is easy to break or damage at the "climbing" position and affect the function of the capacitive touch panel

A jumper structure in a touch sensor and a fabricating method thereof, as well as a capacitive touch panel using the jumper structure, wherein the jumper structure crosses an insulating layer separating two adjacent touch sensors and electrically connects said two touch sensors, the jumper structure comprising: a first bridging part being conductive and transparent and a second bridging part made of metal material, the first bridging part covering the insulating layer, the second bridging part respectively passing a climbing portion of the insulating layer at both ends of the first bridging part and electrically connected to said two adjacent touch sensors; the jumper of the present invention resolves the fragile and visual problems in the climbing portions of conventional ITO (indium tin oxide) jumpers.
Description
Technical field [0001] The present invention relates to a structure of a touch sensor used in a capacitive touch panel and a manufacturing method thereof, in particular to a jumper wire of a touch sensor, a manufacturing method and a capacitive touch panel using the jumper wire. Background technique [0002] In the existing touch panel, a sensing area is arranged on a substrate surface, and the position of a finger or its substitute (such as a stylus) is sensed by the sensing area to achieve the purpose of touch. There are many types of touch panels, which can be divided into resistive, capacitive, electromagnetic, infrared, and surface acoustic wave types according to their detection methods and structures. Among them, capacitive touch panels are the current mainstream products. A known capacitive touch panel is a transparent substrate (such as a glass substrate) along the first direction (such as the X-axis direction) and a second direction (such as the Y-axis direction) arrang...
