Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a touch control component and a display device. Background technique [0002] The conventional large-size capacitive touch screen design is to converge the channels in the touch substrate surface to several binding areas through edge wiring, and then connect the flexible circuit (Flexible Printed Circuit, FPC for short) through the binding areas. The FPC Unicom adapter board then realizes Unicom. For example, the routing structure of the binding area in the prior art touch substrate is as follows: figure 1 As shown, the channel Tx formed by the transmitting electrode 22 and the channel Rx formed by the receiving electrode 23 are extended and connected to the edge wiring 25 in the edge area, and pass through the connection point 24 (the point where the in-plane channel of the touch substrate is usually connected to the wiring. Called C-pad) converges to the bonding ...

Problems solved by technology

In addition, according to the current design structure, the position, quantity, and width of the metal trace of the flexible circuit have been fixed. Considering that even if it is only the change of the wiring, the in-plane structure of the touch substrate can only be redesigned by reopening the mask. It is difficult to realize the sharing of the mask, which greatly increases the development cost and development time, and for Reducing the impedance and ensuring the performance of the touch screen cannot play a substantial role, and the electrostatic discharge (Electro-Static Discharge, ESD) ability of the edge wiring is not good.
