Metal grid, touch sensing element and preparation method thereof, touch screen and electronic device

Abstract

The invention discloses a metal grid, a touch sensing element and a preparation method thereof, a touch screen and electronic equipment. The metal grid includes: a plurality of metal grid blocks; and a plurality of invalid grid blocks, the plurality of invalid grid blocks are spaced apart from the plurality of metal grid blocks, wherein the invalid grid blocks At least one of is composed of a plurality of sub-grid blocks arranged at intervals. The metal grid can significantly reduce the influence of short circuits on data signals in metal grid touch products such as touch screens caused by metal particles falling on the gaps between metal grid blocks and invalid grid blocks.

Description

technical field [0001] The invention belongs to the field of electronic technology, in particular, the invention relates to a metal grid, a touch sensing element and a preparation method thereof, a touch screen and electronic equipment. Background technique [0002] As a simple way of human-computer interaction, the touch screen is widely used in various electronic devices, such as mobile phones, IPAD, etc., especially the capacitive touch screen, which pastes a layer of metal conductive material on the upper and lower surfaces of the insulating material, when there is When a conductive object (finger) touches, the current induction of the human body will work, so that the surface capacitance of the surface electric shock will change, so the position of the touch point can be measured, and more and more people are attracted by the sensitive response of the capacitive touch screen. of favor. At present, metal conductive substances on insulating materials mostly use metal gri...

AI Technical Summary

Problems solved by technology

However, during the production process of metal grid touch products, it is inevitable that some metal particles will randomly fall on the surface of the metal grid. When the metal particles fall just at the interval between the metal grid block and the invalid grid block, it will cause The metal grid block here is short-circuited, and the short-circuit of this weak connection will cause a large change in the data signal detected by the IC. When the change exceeds the touch threshold, the TP will automatically report the point, resulting in The touch screen does not work properly

[0003] Therefore, there is still room for improvement for capacitive touch screens
