Problems solved by technology
like figure 1 As shown, an existing touch lead structure 10 includes a first metal lead 11, an insulating layer 13 and a second metal lead 12 stacked in sequence. The end of the insulating layer 13 to which the lead wire 11 is bonded is easily warped, which in turn causes the second metal lead wire 12 bonded above the insulating layer 13 to warp and break, causing subsequent process problems and reducing product yield

Provided is a touch lead structure. The structure includes multiple first metal leads, an insulated layer and multiple second metal leads, wherein the first metal leads, the insulated layer and the second metal leads are laminated in sequence; the first metal leads are parallelly fitted on a glass substrate at intervals, the second metal leads and the first metal leads are arranged in a one-to-onecorresponding mode, the first metal leads are provided with a net-shaped hollow area, the insulated layer extends from one end of each first metal lead along the first metal leads to the net-shaped hollow area and is in fitted connection with the glass substrate below the net-shaped hollow area, one part of each second metal lead is in fitted connection with the insulated layer, the other part ofeach second metal lead is in fitted connection with the part, where the insulated layer is not arranged, of the corresponding first metal lead, and the ends, where the insulated layer is fitted, of the second metal leads and first metal leads are used for being electrically connected with a touch sensing layer. The invention further provides a touch lead structure manufacturing method. Accordingto the touch lead structure, the insulated layer is fitted with the glass substrate through the net-shaped hollow area on the first metal leads, and therefore the second metal leads are not easy to cock and disconnect.
Description
technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch lead structure and a manufacturing method thereof. Background technique [0002] With the development of the information age and the acceleration of the pace of life, touch technology has gradually replaced the traditional mouse and keyboard due to its humanized design and simple and fast input, and is widely used in various electronic products. Among them, the touch display panel is widely used due to its advantages of fast response, high sensitivity, good reliability and high durability. [0003] According to the different setting methods of the touch sensing layer in the display panel, the touch display panel is divided into an external type, a single glass touch type (One Glass Solution, OGS), an embedded type (In-Cell) and an external type ( On-Cell) and other structures. In the On-Cell touch display panel, the touch sensing layer is arranged outside ...
