Referring to FIGS. 4 to 7, FIG. 4 is a schematic structural diagram of a, touch control module provided by an embodiment of the present application.

As shown in FIG. 4, in one embodiment, the touch control module 100 of the present application includes a touch control layer 20, a plurality of touch control leads 30, and a driving chip 40.

The touch control layer 20 includes a plurality of touch control groups A arranged at intervals; each of the touch control groups A includes a plurality of touch control units 21, and adjacent ones of the touch control units 21 are spaced apart from each other. In one embodiment, the touch control unit 21 has a grid shape. Of course, the structure of the touch control unit 21 is not particularly limited thereto. The touch control unit 21 is made of a metal material and a transparent conductive material, including at least one of copper, aluminum, titanium, and indium tin oxide. In one embodiment, as shown in FIG. 4, the plurality of touch control units in the touch control group A are arranged in a vertical direction, that is, the touch control group A is equivalent to the touch control column. In another embodiment, as shown in FIG. 5, a plurality of touch control units in the touch control group A are arranged in a horizontal direction, that is, the touch control group A is equivalent to the touch control row. In a preferred embodiment, a distance between adjacent ones of the touch control units 21 is smaller than a preset distance. Since the distance between the touch control units 21 is reduced, a space occupied by the touch control leads can be reduced, thereby reducing an area of the blind area and improving the sensitivity of the touch control function.

The touch control leads 30 correspond to the touch control units 21, and one end of the touch control lead 30 is connected to the corresponding touch control unit 21. In one embodiment, the touch control leads 30 can be connected to the touch control units 21 in a one-to-one correspondence. A total number of the plurality of setting touch control leads between adjacent ones of the touch control groups A is less than a preset number, and the setting touch control leads are touch control leads arranged in the same direction. Taking FIG. 4 as an example, for example, the touch control leads 30 between adjacent ones of the touch control columns are generally arranged in the vertical direction, and the touch control leads are set to be touch control leads 30 arranged in the vertical direction. The total number of the setting touch control leads between adjacent ones of the touch control columns is 4; and the total number of the setting touch control leads between adjacent ones of the touch control columns in FIG. 2 is 9, It can be seen that the total number of the setting touch control leads between adjacent ones of the touch control columns in FIG. 4 is less than the total number of the setting touch control leads between adjacent ones of the touch control columns in FIG. 2. The structure of FIG. 7 is the same as those in FIGS. 2 and 4, and not repeated herein for brevity.

Taking FIG. 5 as an example, for example, the touch control leads 30 between adjacent ones of the touch control rows are generally arranged to the left or right, and the setting touch control leads are the touch control leads arranged to the left or to the right, and the total number of the setting touch control leads between adjacent ones of the touch control rows is 3. The total number of the setting touch control leads between adjacent ones of the touch control columns in FIG. 2 is 9. The total number of the setting touch control leads between adjacent ones of the touch control rows in FIG. is less than the total number of the setting touch control leads between adjacent ones of the touch control columns in FIG. 2. The structure of 6 is similar to those above, and will not be repeated herein for brevity. Therefore, the space occupied by the touch control leads 30 can be reduced, thereby reducing the area of the blind area and improving the sensitivity of the touch control function. In a preferred embodiment, in order to simplify the manufacturing process, the touch control leads 30 and the touch control units 21 are arranged in the same layer and made of the same material.

The driving chip 40 is connected to another end of the touch control lead 30. In one embodiment, the touch control module of the present application is in a self-capacitive touch control mode.

In one embodiment, the touch control lead 30 includes a first connecting portion 31, a trunk portion 32, and a second connecting portion 33, and one end of the trunk portion 32 is connected to a corresponding one of the touch control units through the first connecting portion 3121, another end of the trunk portion 32 is connected to the drive chip 40 through the second connecting portion 33, the touch control layer 20 includes a setting side 22 and a non-setting side 23; A length of the setting side 22 is greater than a length of the non-setting side 23; that is, the setting side 22 is the long side, and the non-setting side 23 is the short side. An arrangement direction of the trunk portion 32 is same as a direction of the non-setting side 23, that is, the arrangement direction of the trunk portion 32 is arranged along a direction of the short side, wherein an area of the touch control layer 20 is larger than a predetermined area, and the preset area is, for example, 8 inches. Because when the area of the touch control layer 20 is greater than the preset area, if the arrangement direction of the trunk portion 32 is the same as a direction of the long side, there are more touch control leads between adjacent ones of the rows of touch control units, so the area of the blind area is increased. If the arrangement direction of the trunk portion 32 is the same as the direction of the short side, the number of the touch control leads between adjacent ones of the rows of touch control units can be reduced. Therefore, the area of the blind area is reduced, and the sensitivity of the touch control function is improved. It is understandable that the preset area is not particularly limited to 8 inches, and can be specifically set according to requirements.

In one embodiment, in order to further reduce the space occupied by the touch control leads 30, a distance between adjacent ones of the touch control leads 30 is within a preset range.

The preset length can be a length of an existing touch control unit. In one embodiment, when the trunk portion 32 is arranged along the length direction of the touch control screen 20, the length of the touch control unit 21 (the size in the vertical direction) is increased, thereby reducing a number of the touch control units 21 and a number of the touch control leads 30 in the vertical direction, thus further reducing the total area and space occupied by the touch control leads 30.
