Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. In the drawings, the size and thickness of the components depicted in the drawings are not to scale for clarity and ease of understanding and description.
As shown in fig. 1, which is a schematic basic structure diagram of a touch display panel according to an embodiment of the present invention, the touch display panel 10 includes a display area A1 and a binding area A2 located at one side of the display area A1, at least one touch electrode set 20 is disposed in the display area A1 (only one touch electrode set 20 is shown in fig. 1 for illustration), and any one touch electrode set 20 includes N touch electrodes 201 arranged along a direction from the display area A1 to the binding area A2, where N is an integer greater than 1; the binding area A2 is internally provided with a touch integrated circuit 30, in one touch electrode group 20, M touch electrodes 201 far away from the binding area A2 are respectively electrically connected with the touch integrated circuit 30 through at least two touch wires 40, the at least two touch wires 40 are connected in parallel, and M is a positive integer less than N.
It can be understood that, as the size of the panel is larger, the longer the length of the touch trace between the touch electrode far away from the binding area and the touch integrated circuit is, i.e. the larger the load is, the smaller the charging current of the touch electrode is, i.e. the charging time is prolonged, which affects the point reporting rate of self-contained touch. According to the invention, the M touch electrodes 201 far from the binding area A2 are respectively and electrically connected with the touch integrated circuit 30 through the at least two touch wires 40, and the at least two touch wires 40 are connected in parallel, so that the impedance of the touch wires 40 far from the binding area A2 can be reduced, namely the load of the touch wires 40 far from the binding area A2 is reduced, the charging time of the touch electrodes 201 is reduced, and the self-contained touch point reporting rate is improved.
It should be noted that, in fig. 1, n=4 and m=1 are only taken as an example for illustration, that is, in fig. 1, one touch electrode group 20 includes 4 touch electrodes 201, one touch electrode 201 far away from the binding area A2 is electrically connected with the touch integrated circuit 30 through two touch wires 40, and the two touch wires 40 are connected in parallel, that is, the impedance of the touch wire 40 corresponding to the one touch electrode 201 far away from the binding area A2 is reduced, the load of the touch wire 40 is reduced, the charging time of the touch electrode 201 is reduced, and the point reporting rate of self-capacitance touch is improved. In other embodiments, M may be 2 or 3, that is, two touch electrodes 201 far from the binding area A2 are electrically connected to the touch integrated circuit 30 through at least two touch traces 40 respectively, or three touch electrodes 201 far from the binding area A2 are electrically connected to the touch integrated circuit 30 through at least two touch traces 40 respectively.

It can be appreciated that the two touch wires (401 and 402) are connected in parallel, so that the impedance can be reduced; the touch electrode 201 is electrically connected with the touch trace 401 through the 2 first vias 50, so that the situation that signal transmission cannot be performed between the touch electrode 201 and the touch trace 401 due to incomplete etching of a certain first via 50 can be avoided.
With continued reference to fig. 1, in one embodiment, the at least two touch traces 40 are parallel to each other, and a parallel loop is formed between two adjacent touch traces 40 through a connection line 60. It can be appreciated that one end of each of the two touch traces (401 and 402) is electrically connected to the same touch electrode 201 through the first via 50, and the other end is electrically connected through the connecting wire 60, that is, a parallel circuit is formed, which is equivalent to parallel connection of two resistors, so as to reduce the total impedance.
Specifically, in one embodiment, one end of a first touch trace 401 of the at least two touch traces 40 is electrically connected to the touch electrode 201 through the first via 50, and the other end is electrically connected to the touch integrated circuit 30; one end of the touch trace 402 of the at least two touch traces 40 except the first touch trace 401 is electrically connected to the touch electrode 201 through the first via 50, and the other end is electrically connected to the first touch trace 401 through the connecting wire 60.

It can be appreciated that, in this embodiment, by setting the number of the touch traces 40 electrically connected to one touch electrode 201 to gradually increase along the direction away from the bonding area A2, the more the number of the touch traces 40 connected in parallel to the touch electrode 201 further from the bonding area A2, the more the corresponding impedance decreases after being connected in parallel, and compared with the embodiment of fig. 1, the impedance of all the touch traces 40 of the touch display panel 10 is further balanced, so that the longer the impedance of the touch electrode 201 is avoided, and the charging time is prolonged.
