The touch film, the control panel and the home appliance provided by the embodiment of the present disclosure are exemplarily described below with reference to fig. 1 to 4.
Fig. 1 is a schematic structural diagram of a touch film according to an embodiment of the disclosure. Referring to fig. 1, the touch film 100 includes: a touch area 10 and a shielding area 20, the shielding area 20 being provided on at least one side of the touch area 10; a touch structure 11 is arranged in the touch area 10, and the touch structure 11 is used for responding to the touch action of a user to generate a corresponding touch signal; a shielding structure 21 is disposed in the shielding region 20, and the shielding structure 21 is used for shielding interference signals outside the touch region 10.
The touch film 100 is attached to the touch panel and electrically connected to the main control panel. The touch film 100 is sequentially provided with a film layer, a printed pattern layer, a conductive circuit layer and an injection molding layer from top to bottom, and the injection molding layer is in touch with the touch panel; the touch structure 11, the shielding structure 12 and the signal lines connected with the touch structure are all arranged on the conductive circuit layer. When a user touches the touch structure 11, capacitance change is generated between the touch structure 11 and the finger of the user, so that a corresponding touch signal is generated, and the touch signal is transmitted to the main control board through a touch signal line 12 connected with the touch structure 11, so that triggering of a corresponding function of the touch structure 11 is realized.
The shielding region 20 may be disposed on a side of the touch region 10 where the interference signal exists, or on a side of the touch region near the electronic component generating the interference signal, or, as shown in fig. 1, the shielding region 20 encapsulates the touch region 10 in a cavity formed by the shielding region. Thus, when the interference signal exists, the shielding structure 21 arranged in the shielding area 20 receives the interference signal first, so that the interference signal outside the touch area 10 can be shielded, and the interference to the touch area 10 is reduced.
It should be noted that fig. 1 only exemplarily illustrates that the shielding structure 21 is a shielding coil, but does not constitute a limitation of the touch film provided by the embodiments of the present disclosure. In other embodiments, the shielding structure 21 may be provided as any type of electronic component or electronic structure having a signal shielding function known to those skilled in the art, and is not limited herein.
The embodiment of the disclosure provides a touch film, which is characterized in that a shielding region 20 is arranged on at least one side of a touch region 10, and interference signals outside the touch region 10 are shielded by using a shielding structure 21 arranged in the shielding region 20, so that interference to the touch region 10 is reduced, and accurate identification of the touch signals is realized.
In some embodiments, as shown in fig. 2, a schematic structural diagram of another touch film according to an embodiment of the disclosure is provided. Referring to fig. 2, the touch film 100 further includes: a non-touch area 30; the non-touch area 30 is disposed immediately adjacent to the touch area 10; the shielding region 20 envelopes the touch region 10 and the non-touch region 30.
The non-touch area 30 is a routing area of the touch signal line 12 connected to the touch structure 11, and the touch signal line 12 is routed in the non-touch area 30 and extends out of the film body range of the touch film 100. The non-touch area 30 may be arranged left and right with the touch area 10 (as shown in fig. 2), or the non-touch area 30 may be arranged up and down with the touch area 10, which is not limited herein.
The shielding structure 21 is configured to shield the interference signals outside the touch area 10 and the non-touch area 30, so as to further reduce the influence range of the interference signals.
The touch region 10, the shield region 20, and the non-touch region 30 are distributed within the film body region of the touch film 100, and as shown in fig. 2, the rounded rectangle represents the film body region of the touch film 100, which is the region to be bonded to the touch panel.

It can be appreciated that fig. 2 illustrates only two touch areas, non-touch areas, and shielding areas by way of example, but does not constitute a limitation of the touch film provided by the embodiments of the present disclosure. In other embodiments, the number of the touch area, the non-touch area, and the shielding area may be flexibly set according to the requirements of the touch film, which is not limited herein.
In some embodiments, as shown in fig. 2, the touch film 100 further includes: a touch signal line 12 connected to the touch structure 11 for transmitting a touch signal; a shielding signal line 22 connected to the shielding structure for transmitting a shielding signal; the tail of the touch signal line 12 and the tail of the shield signal line 22 are disposed at one end of one side of the touch film.
Each touch structure 11 is individually connected with one touch signal line 12, so that only when the corresponding touch structure 11 is touched, a touch signal can be transmitted through the touch signal line 12 uniquely corresponding to the touch structure, signal transmission is achieved, no external interference exists, signal transmission is fast, and sensitivity is good during operation and use.
Wherein, in the touch area 10, each touch signal line 12 shuttles between the gaps of each touch structure 11 and does not overlap any one touch structure 11 and other touch signal lines 12; the touch signal lines 12 extend into the non-touch area 30 and converge into a row at the edge of the non-touch area 30, with each touch signal line 12 also not overlapping within the non-touch area 30. The shield signal lines 22 are disposed around the touch signal lines 12 to completely envelop all of the touch signal lines 12 distributed within the touch area 10 and the non-touch area 30. After the touch signal lines 12 and the shielding signal lines 22 are converged into a row at the edge of the non-touch area 30, the touch signal lines 12 and the shielding signal lines 22 continue to extend and form a tail band 40 beyond the film body range of the touch film; the tail band 40 is disposed at one end of one side of the touch film 100, and is located closer to the non-touch area 30, and the distance between the tail band 40 and the touch area 10 is greater than the distance between the tail band and the non-touch area 30, so that the sensitivity of the touch area 10 is not affected during installation.
It should be noted that fig. 2 illustrates only an exemplary configuration in which the tail band 40 is disposed at one end of one side of the touch film, such as the left end or the right lower end of the lower side of the touch film illustrated in fig. 2, but is not limited to the touch film provided in the embodiments of the present disclosure.

In the related art, as shown in fig. 3, the touch signal lines 12 are symmetrically distributed on both sides of a symmetry axis with the longitudinal center line of the touch film 100 as the symmetry axis. When the touch signal is sampled, a plurality of noise signals are generated, and when the touch signal lines 12 are positioned right below a touch area, the interference current directions on the touch signal lines are the same and the amplitudes are the same due to the small distance between the touch signal lines, so that common-mode interference is generated; the symmetrical distribution of the touch signal lines 12 causes electromagnetic waves of the interference signals to resonate, and the intensity of the interference signals is enhanced.
In this embodiment, in order to overcome the above technical problems, the tail bands of the touch signal lines 12 are disposed on the same side of the symmetry axis of the touch area 10, that is, the touch signal lines 12 are disposed asymmetrically, so as to effectively avoid signal common mode interference and reduce interference to the touch area.
It should be noted that fig. 3 only exemplarily illustrates that the tail bands of the touch signal lines 12 are disposed on the same side of the symmetry axis with the longitudinal central axis of the touch area as the symmetry axis, but does not limit the touch film provided by the embodiments of the present disclosure.
