Background
The conventional touch module includes a resistive touch module and a capacitive touch module. The resistive touch module performs touch operation by pressing, and has less limitation on operation conditions, but is inferior to the capacitive touch module in smoothness of sensing (especially for users who need to frequently write and draw).

Moreover, both the resistive touch module and the capacitive touch module have the defect that users are easy to touch by mistake.
In addition, if the resistive touch module and the capacitive touch module are combined together only by a common method (e.g., bonding), the touch module has both the resistive touch function and the capacitive touch function, which may result in the defects of over-thick thickness, poor integration, and high material cost of the product.

[ first embodiment ]
Referring to fig. 1, 2 and 4, a first embodiment of the present invention is shown. The embodiment discloses a hybrid touch module 100, which can be used to provide a resistive touch function and a capacitive touch function, and the hybrid touch module 100 can be applied to electronic products such as smart phones, tablet computers, notebook computers, or industrial computers. The hybrid touch module 100 includes a bottom layer structure 1, a common layer structure 2 disposed on the bottom layer structure 1, a top layer structure 3 attached to the common layer structure 2, and a protection structure 4 attached to the top layer structure 3. Furthermore, the hybrid touch module 100 further includes a common controller 5 electrically connected to the bottom layer structure 1, the common layer structure 2, and the top layer structure 3 (see fig. 4). The specific structure of each component of the hybrid touch module 100 of the present embodiment will be described below, and then the connection relationship between each component of the hybrid touch module 100 will be described in due course.
The bottom layer structure 1 includes a substrate 11, a conductive layer 12, a frame 13, and a plurality of spacers 14. The conductive layer 12 is disposed on a top surface 111 of the substrate 11, and the frame 13 and the spacers 14 are disposed on the conductive layer 12, respectively. The spacers 14 are disposed on the conductive layer 12 separately and are located inside the frame 13.
In the present embodiment, the material of the substrate 11 is preferably, but not limited to, transparent Glass (Glass) with a relatively thick thickness and a relatively high hardness; the material of the conductive layer 12 is preferably, but not limited to, Indium Tin Oxide (ITO), Fluorine Tin Oxide (FTO), Antimony Tin Oxide (ATO), or carbon ink conductor (carbon); the material of the frame 13 is preferably, but not limited to, transparent adhesive glue (e.g., ADH); and the material of the spacer 14 is preferably, but not limited to, an insulating spacer ball (spacer dot).
More specifically, the substrate 11 may be a rectangular plate, the conductive layer 12 may be a film and completely cover the top surface 111 of the substrate 11, and the frame 13 may be a rectangular ring and may be disposed at a peripheral portion of the conductive layer 12. The spacers 14 are regularly arranged at the conductive layer 12 where the frame 13 is not disposed, and the height of each spacer 14 is lower than the height of the frame 13.
The common layer structure 2 is disposed and attached on the frame 13, and is spaced apart from the conductive layer 12. The common layer structure 2 includes a common film 21, a conductive layer 22 for resistance, and a conductive layer 23 for capacitance. The common film 21 has a first surface 211 and a second surface 212 on opposite sides, and the first surface 211 faces the top surface 111 of the substrate 11. That is, the first surface 211 is closer to the top surface 111 of the substrate 11 than the second surface 212.
In this embodiment, the common film 21 may be a rectangular thin film having a shape corresponding to the substrate 11, and the resistive conductive layer 22 and the capacitive conductive layer 23 are commonly disposed on the first surface 211 of the common film 21 (as shown in fig. 1, the reference numerals 22 and 23 are in the same layer structure). More specifically, as shown in fig. 2, the conductive layer 22 for resistance and the conductive layer 23 for capacitance are disposed on the first surface 211 of the common film 21 at intervals, and the plurality of electrode lines of the conductive layer 22 for resistance surround and form a plurality of receiving grooves 24, while the plurality of electrode lines of the conductive layer 23 for capacitance are disposed in the plurality of receiving grooves 24, respectively. Thereby, the conductive layer for resistance 22 and the conductive layer for capacitance 23 can be electrically insulated from each other without contacting each other when they are provided in common on the first surface 211 of the common film 21.
With reference to fig. 1, the spacers 14 of the bottom layer structure 1 face the common layer structure 2 and are spaced apart from the common layer structure 2. Thereby, the plurality of spacers 14 can be used to prevent the conductive layer 22 for resistance from contacting the conductive layer 12 of the underlying structure 1 without being pressed, thereby preventing occurrence of a short circuit or a signal misjudgment.
The top layer structure 3 may include an optically transparent adhesive 33 (e.g., ADH, OCA) for being attached to the common layer structure 2 through the optically transparent adhesive 33, but the invention is not limited thereto. In more detail, the top layer structure 3 includes an insulating film 31 and an electrode layer 32. The insulating film 31 has a bottom surface 311 and a top surface 312 on opposite sides, and the bottom surface 311 of the insulating film 31 faces the second surface 212 of the common film 21. That is, the bottom surface 311 is closer to the second surface 212 of the common film 21 than the top surface 312.
In this embodiment, the insulating film 31 may be a rectangular film having a shape corresponding to the substrate 11. The electrode layer 32 is formed in a film shape and completely covers the bottom surface 311 of the insulating film 31. The electrode layer 32 is provided at a distance from the conductive layer for resistance 22 and the conductive layer for capacitance 23. In more detail, the electrode layer 32 is located between the insulating film 31 and the common film 21, and the electrode layer 32 is attached to the common film 21 through the optically transparent adhesive 33.
In the present embodiment, the materials of the common film 21 and the insulating film 31 are preferably, but not limited to, transparent glass or plastic (e.g., polyethylene terephthalate) with a small thickness and a low hardness; the materials of the conductive layer 22 for resistance, the conductive layer 23 for capacitance, and the electrode layer 32 are preferably, but not limited to, Indium Tin Oxide (ITO), Fluorine Tin Oxide (FTO), Antimony Tin Oxide (ATO), or carbon ink conductor (carbon).
According to the above configuration, the hybrid touch module 100 of the present embodiment can provide the resistive touch function by the mutual matching of the conductive layer 22 for the resistor of the common layer structure 2, the conductive layer 12 of the bottom layer structure 1 and the plurality of spacers 14. Furthermore, the hybrid touch module 100 of the present embodiment can provide a capacitive touch function by the mutual matching of the conductive layer 23 for the capacitor of the common layer structure 2, the insulating film 31 and the electrode layer 32 of the top layer structure 3.
Since the hybrid touch module 100 has both the resistive touch function and the capacitive touch function, when a user performs a touch operation, the hybrid touch module 100 can simultaneously perform the resistive touch function and the capacitive touch function, thereby performing double confirmation and preventing an erroneous touch. In addition, the hybrid touch module 100 can provide a wider range of operating conditions for users; that is, the user can smoothly use the hybrid touch module 100 even when wearing gloves, the environment is not good, or the user is raining.
Furthermore, the hybrid touch module 100 can be designed and configured in a position by the common layer structure 2, so that the hybrid touch module 100 has a very high degree of integration (the resistive touch function and the capacitive touch function are skillfully integrated in one device), and the thickness and material cost of the hybrid touch module 100 can be effectively reduced.
Further, the protection structure 4 includes a transparent plate 41 (e.g., cover glass), a shielding film 42 (e.g., black ink), and another optically transparent adhesive 43 (e.g., ADH, OCA). The transparent plate 41 can be attached to the insulating film 31 of the top layer structure 3 through the other optically transparent adhesive 43, and the transparent plate 41 is located on the side of the top layer structure 3 away from the common layer structure 2 (in fig. 1, above the top surface 312 of the insulating film 31). The shielding film 42 is located between the transparent plate 41 and the top layer structure 3, and is used to define a non-visible region (i.e. a black frame portion of the touch module) of the hybrid touch module 100.
Wherein, a projection area formed by orthographic projection of the frame 13 of the bottom layer structure 1 towards the protection structure 4 falls on the shielding film 42. Therefore, the frame 13 and the shielding film 42 can have a preferable position configuration relationship, so as not to affect the touch function and the light transmission effect of the hybrid touch module 100.
In more detail, the transparent plate 41 may be a rectangular plate body having a shape corresponding to the substrate 11. The shielding film 42 is in a rectangular ring shape and is disposed at a peripheral portion of the transparent plate 41 (the shape and position of the shielding film 42 correspond to the frame 13). The thickness of the shielding film 42 is smaller than the thickness of the transparent plate 41 and also smaller than the thickness of the optically transparent adhesive 43. Preferably, the masking film 42 is partially recessed into the optically clear adhesive 43, but the invention is not so limited.
Referring to fig. 4, the common controller 5 is electrically connected to the conductive layer 12 of the bottom layer structure 1, the conductive layer 22 for the resistor and the conductive layer 23 for the capacitor of the common layer structure 2, and the electrode layer 32 of the top layer structure 3. Therefore, the common controller 5 can be used to control at least one of the resistive touch function and the capacitive touch function to be executed.
It should be noted that the resistive touch module and the capacitive touch module in the prior art are two independent structures, and therefore, a resistor controller and a capacitor controller must be electrically connected to each other, so that the product has an excessively large volume and the manufacturing cost of the product is excessively high. In contrast to the above disadvantages, the hybrid touch module 100 of the present embodiment only needs to be electrically connected to one common controller 5 to perform the resistive touch function and the capacitive touch function, so that the volume and the manufacturing cost of the hybrid touch module 100 can be effectively reduced.
[ second embodiment ]
Fig. 3 shows a second embodiment of the present invention. The embodiment discloses a hybrid touch module 100, which includes a bottom layer structure 1, a common layer structure 2, a top layer structure 3, a protection structure 4, and a common controller 5. The structural design and the positional arrangement relationship of the substructure 1, the protective structure 4, and the common controller 5 of the present embodiment are substantially the same as those of the first embodiment. The difference lies in the structural design and the location configuration of the common layer structure 2 and the top layer structure 3. The differences of the present embodiment from the first embodiment will be explained below.
The capacitor conductive layer 23 of the common layer structure 2 of the present embodiment is disposed on the second surface 212 of the common film 21, and the electrode layer 32 of the top layer structure 3 is disposed on the top surface 312 of the insulating film 31. That is, the conductive layer 22 for resistance and the conductive layer 23 for capacitance of the present embodiment are respectively disposed on the first surface 211 and the second surface 212 of the common film 21, but are not commonly disposed on the first surface 211 of the common film 21.
Furthermore, the electrode layer 32 of the top layer structure 3 of the present embodiment is disposed on the top surface 312 of the insulating film 31, but not on the bottom surface 311 of the insulating film 31. Therefore, in the present embodiment, the capacitor conductive layer 23 is located between the common film 21 and the insulating film 31, and the electrode layer 32 is located between the insulating film 31 and the transparent plate 41.
More specifically, the conductive layer 22 for resistance and the conductive layer 23 for capacitance in the present embodiment are not limited to the configuration (having a plurality of electrode lines) as in the first embodiment, and the conductive layer 22 for resistance and the conductive layer 23 for capacitance may be, for example, in the form of a film and completely cover the first surface 211 and the second surface 212, respectively.
[ third embodiment ]
Referring to fig. 5 and 6, a third embodiment of the present invention is shown. The embodiment discloses a hybrid touch module 100, which includes a bottom layer structure 1, a common layer structure 2, a protection structure 4, and a common controller 5. The structural design of the components of this embodiment is substantially the same as that of the second embodiment. The greatest difference between the present embodiment and the second embodiment is that the hybrid touch module 100 of the present embodiment does not have the top layer structure 3. The differences of the present embodiment from the first embodiment will be explained below.
Since the hybrid touch module 100 of the present embodiment does not have the top layer structure 3, the hybrid touch module 100 of the present embodiment provides a capacitive touch function by sharing the conductive layer 23 for the capacitor and the common film 21 of the layer structure 2. That is, the common layer structure 2 alone can provide a capacitive touch function without being matched with other structure layers.
The transparent plate 41 of the protection structure 4 is disposed and adhered to the conductive layer 23 of the common layer structure 2 through the optically transparent adhesive 43, and the transparent plate 41 is located at a side of the common layer structure 2 away from the underlying structure 1 (as shown in fig. 5, above the second surface 212 of the common film 21). The shielding film 42 of the protection structure 4 is located between the transparent plate 41 and the common layer structure 2, and is used for defining a non-visible region of the hybrid touch module 100. A projection area formed by orthographic projection of the frame 13 towards the protection structure 4 falls on the shielding film 42.
Referring to fig. 6, the common controller 5 is electrically connected to the conductive layer 12 of the bottom layer structure 1, and the conductive layer 22 for resistance and the conductive layer 23 for capacitance of the common layer structure 2, so that the common controller 5 can control at least one of the resistive touch function and the capacitive touch function to be performed.
[ technical effects of the embodiments of the present invention ]
In summary, the hybrid touch module 100 disclosed in the embodiment of the invention can provide a resistive touch function by the mutual matching of the common layer structure 2 and the bottom layer structure 1, and can provide a capacitive touch function by the mutual matching of the common layer structure 2 and the top layer structure 3 (or the common layer structure itself). Therefore, when a user performs a touch operation, the hybrid touch module 100 can simultaneously perform a resistive touch function and a capacitive touch function, so as to perform double confirmation and prevent an erroneous touch. In addition, the hybrid touch module 100 can provide wider operation conditions for users; that is, the user can smoothly use the hybrid touch module 100 even when wearing gloves, the environment is not good, or the user is raining.
Further, the hybrid touch module 100 can be designed and configured in a position by the common layer structure 2, so that the hybrid touch module 100 has a very high degree of integration, and the thickness and material cost of the hybrid touch module 100 can be effectively reduced.
