Abstract

The invention provides a touch control sensor and a preparing method thereof and a touch control display device. The method comprises the steps that a first flexible substrate is covered with a first conductive material, so that a first conductive layer is formed, the surface, away from the first flexible substrate, of the first conductive layer is subjected to first etching processing, so that one or more first binding points are formed, and the first binding points are used for being electrically connected with an external circuit; a second flexible substrate is covered with a second conducive material, so that a second conductive layer is formed, one or more second binding points are formed on the surface, away from the second flexible substrate, of the second conductive layer, and the second binding points are used for being electrically connected with the external circuit; the first conductive layer is attached to the second conductive layer through adhesives, a circuit board to be salified is obtained and subjected to hot pressing processing, and the touch control sensor is obtained. By adoption of the preparing method, the position of the binding points of the obtained touch control sensor can be flexibly arranged, and accordingly the technology cost and time cost are greatly saved.

Description

Technical field [0001] The present invention relates to the field of touch display devices, and in particular to a touch sensor, a manufacturing method thereof, and a touch display device. Background technique [0002] The touch screen signal lines are divided into two groups, namely TX and RX. TX is mainly responsible for driving (transmission) and RX is mainly responsible for sensing (receiving). The division of labor between the two groups of signal lines is different, and they cannot overlap or cross. Cross vertically. The two sets of signal lines are respectively distributed in the X direction and Y direction of the touch screen. The larger the size of the touch screen, the larger the channel's loop impedance. The impedance can be divided into: touch screen touch area impedance and edge trace impedance, while the silver paste (Ag) printed on the screen effectively reduces The impedance of the trace. [0003] For touch screens, they are generally customized according to the ...
