The manufacturing method of the touch-sensitive display device in the embodiment comprises the following steps:
step S10: a preset number of first electrodes are arranged in parallel at intervals, and first electrode leads are arranged on the same side of each first electrode to form a first electrode layer.
In the manufacturing process of the touch-sensitive display device, the first electrode layer is first built by disposing other elements in the first electrode layer on one surface of a substrate. Then, the second electrode layer may be formed by disposing other elements in the second electrode layer on the other surface of the substrate, or two substrates may be disposed to form the first electrode layer and the second electrode layer, respectively. In the process of establishing the first electrode layer, the first electrode is firstly manufactured, the first electrode lead is secondly manufactured, and finally the first electrode and the first electrode lead are attached. The first electrode in the first electrode layer may be made of a conductive material commonly used in the art, such as a TIO conductive material, a nano silver conductive material, a graphene conductive material, or a carbon nanotube conductive material, and the like, and the material for making the first electrode is not particularly limited herein.
In specific implementation, the first electrode may be made of an ITO conductive material by laser etching or yellow light etching, the first electrode may be made of a nano-silver conductive material by laser etching or yellow light etching, and the first electrode may be made of a metal mesh conductive material or an ITO or copper nano-silver conductive material by yellow light etching, which is not specifically limited herein.

And finally, attaching the manufactured first electrode and the first electrode lead.

It should be noted that, the specific manufacturing process of the second electrode in the second electrode layer and the second electrode lead may refer to the manufacturing process of the first electrode and the first electrode lead, and is not described herein again. After the second electrode and the second electrode lead are manufactured, the second electrode and the first electrode need to be vertically arranged in the direction, the second electrode lead is arranged in the blind area of the first electrode, the second electrode lead and the first electrode lead can be arranged in parallel, and certainly the second electrode lead and the first electrode lead can also be arranged in non-parallel. The leading-out direction of the second electrode lead is the same as that of the first electrode lead. The material for forming the second electrode of the second electrode layer may be the same as the material for forming the first electrode, and the specific material for forming the second electrode is not limited.
It should be understood that, during the design of the second electrode lead pattern, a group of second electrode leads may be placed between two adjacent first electrodes, the second electrodes and the second electrode leads are set to be T-shaped structures or double L-shaped structures, a spacing lead is placed between the second electrode leads and the first electrodes, GND, Dummy and Reference functions are set as required, and of course, a plurality of groups of second electrode leads may also be placed between two adjacent first electrodes. In addition, when the second insulating layer is needed, large-area insulation can be adopted, an insulating opening is arranged at the local conducting position, the second insulating layer is established in a printing, magnetron sputtering coating or spraying mode, of course, the insulating layer can also be placed at the overlapping position of the second electrode lead and the second electrode through a printing process, magnetron sputtering coating or spraying of a local strip-shaped insulating layer.

It should be understood that during the manufacturing process, a transparent optical layer may be attached to the upper surface of the electrode layer to reduce the difference in light reflection between the substrate and the electrode layer. In the specific implementation, a single-sided/double-sided blanking coating can be added to the ITO material, the reflection difference between a conductor and a non-conductor is reduced, etching marks are reduced, a blackening layer can be added to the metal conductive material, the reflection of a metal electrode is reduced, and metal grid line marks are reduced.
Step S40: and adhering the lower surface of the first electrode layer to the upper surface of the second transparent optical layer along the arrangement direction of the first electrode lead and the second electrode lead so as to generate the touch sensing display device.
It should be noted that, in order to increase the screen occupation ratio between the three sides and the lead lines, at this time, the lower surface of the first electrode layer and the upper surface of the second electrode layer need to be attached to each other along the direction in which the first electrode lead line and the second electrode lead line are disposed, so as to form a complete touch sensing display device.
