Problems solved by technology
However, as we all know, a major disadvantage of the Metal Mesh design is that it is prone to moiré. The LCM (Liquid Crystal Module) specification on board has a decisive effect on the angle of the grid and the distance between the metal lines, that is, the density of the metal lines.
Therefore, reducing the channel impedance by increasing the trace density will exacerbate the moiré problem
In addition, increasing the wire width and thickness of the metal wire will greatly increase the problem of the disappearance of the metal wire, and the production cost will also increase to a certain extent.
Although people are working hard to develop a lower-resistance metal wire solution, the current process capability is not mature enough. Under the current process level, it is of great significance to effectively reduce the channel impedance by improving the design scheme.

According to the touch structure, the touch substrate, the manufacturing method of the touch substrate and the display device, the electrical performance of the touch structure can be well improved.
Description
technical field [0001] The present invention relates to the field of touch technology, in particular to a touch structure, a touch substrate and a manufacturing method thereof, and a display device. Background technique [0002] At present, metal mesh (Metal Mesh) is widely used in touch screens, which is mainly due to its very fast signal transmission speed, which can greatly reduce RC Delay (resistor capacitance delay), so that the signal transmission speed can reach ordinary ITO ( Indium tin oxide) touch screen is several times to dozens of times. [0003] In the touch screen industry, metal grids are widely used. Due to their fast signal transmission speed, people are more and more interested in it, and a lot of manpower and material resources have been invested in its research. As people put forward higher and higher demands on product performance, further research is needed to increase the signal transmission speed of the touch screen to reduce RC Delay. Among them, e...
