Problems solved by technology
see figure 1 As shown, the touch lead structure 30 includes a first metal lead 31, a second metal lead 32, and an insulating layer 33 disposed between the first metal lead 31 and the second metal lead 32. Due to the attachment of the metal and the insulating layer 33 The force is poor, and the end of the insulating layer 33 bonded to the first metal lead 31 is easily warped, causing the second metal lead 32 bonded to the top of the insulating layer 33 to warp and break
However, the existing method for improving the warpage of the end of the insulating layer is to increase the adhesion between the metal lead and the insulating layer 33 by improving the process conditions, which will increase the manpower input and product cost, and also prolong the product production cycle. Product yield cannot be guaranteed

The invention provides a touch lead structure. The touch lead structure comprises the first metal leads, a second metal lead, and an insulating layer glued between the first metal lead and the second metal lead; multiple first metal leads are glued on a glass substrate in parallel at intervals; gaps are symmetrically formed on two sides of the first metal lead; the insulating layer extends to a gap central line L from the upper side of one end of the first metal lead along the first metal lead and is in gluing connection with the glass substrate and the first metal lead at the lower side; one part of the second metal lead is in gluing connection with the insulating layer, the other part of the second metal lead is in gluing connection with the first metal lead without the insulating layer at the upper side; and one end of the second metal lead in gluing connection with the first metal lead is electrically connected with a touch FPC, and the other end is electrically connected with a touch sensing layer. The invention further provides a touch lead structure manufacturing method. The second metal lead of the above mentioned touch lead structure is hard to upwarp and break; and the product yield is improved, the labor cost and the product cost are lowered, and the production period is shortened.
Description
technical field [0001] The 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. The principle of touch screen sensing is that voltage acts on the four corners of the screen sensing area and forms a fixed electric field. When a finger touches, a capacitance change occurs between the human body and the transparent electrode, which can cause the electric field to induce a current, which is measured by the controller. According to the current The contact positio...
