A touch structure and its preparation method, a touch device, and a touch display device

Abstract

Embodiments of the present invention provide a touch control structure and a manufacturing method thereof, a touch control device, and a touch display device, which relate to the field of touch technology and can solve the problem of large capacitance and resistance delay values ​​in existing touch control structures. The touch structure includes a plurality of first touch electrodes and a plurality of second touch electrodes arranged on the base substrate; the first touch electrodes and the second touch electrodes are composed of a first conductive grid structure and arranged on each At least one polygonal pattern in the first grid; the center of the first grid coincides with the center of the polygonal pattern; the material of the polygonal pattern is a conductive material; wherein, at the intersection of the first touch electrode and the second touch electrode After the intersection point of the first conductive grid structure of the first touch electrode coincides with the center of the polygonal pattern of the second touch electrode, the orthographic projection of the first conductive grid structure and the polygonal pattern on the base substrate forms a second The second conductive grid structure, the shapes and sizes of the plurality of second grids in the second conductive grid structure are exactly the same.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch structure and a preparation method thereof, a touch device, and a touch display device. Background technique [0002] At present, the touch electrodes are often made into a metal mesh structure (Metal Mesh) in the touch device. Since the metal mesh structure has a fast signal transmission speed, compared with the ITO (Indium Tin Oxide, Indium Tin Oxide) touch device (touch The control electrode is made of ITO) The transmission speed of the signal can be increased several times to dozens of times, which can greatly reduce the excellent performance such as RC Delay (capacitance resistance delay), so the metal grid structure has been widely used in the field of touch technology . [0003] The touch structure of the touch device in the prior art is as follows: figure 1 As shown, it includes a plurality of strip-shaped first touch electrodes 10 arranged in parallel an...
