[0030] It should be understood that the specific embodiments described herein merely exemplify the application and do not limit the application.

[0031] In the following description, the suffix used for an element such as "module", "part", or "unit" is merely for facilitating the description of the present application, and does not have a specific meaning by itself. Thus, "module", "part", or "unit" can be mixedly used.

[0032] The main solution of the embodiment of the present application is: a touch module, the touch module comprises:

[0033] An inner touch sensing layer, the inner touch sensing layer comprises an inner protective layer, an inner adhesive layer and a first electrode layer which are sequentially attached;

[0034] A middle adhesive layer;

[0035] An outer touch sensing layer, the outer touch sensing layer comprises an outer protective layer, an outer adhesive layer and a second electrode layer which are sequentially attached;

[0036] The first electrode layer of the inner touch sensing layer, the middle adhesive layer and the second electrode layer of the outer touch sensing layer are sequentially attached, and the inner touch sensing layer and the outer touch sensing layer are used for sensing a touch signal, so that an external control chip recognizes a facing of a touch operation corresponding to the touch signal based on the touch signal.

[0037] Since the common touch panel in the prior art is generally attached to the upper surface of the display screen, the touch is performed on the uppermost surface during use to realize touch control, and there is no need for back touch control.

[0038] In some application scenarios of touch screens, for example, a restaurant window, two touch screens inside and outside are generally installed in the prior art, customers inside the restaurant can place orders through the touch screen on the inside of the window, and potential customers outside the restaurant can view the introduction of the restaurant through the touch screen on the outside of the window.

[0039] In this case, if the touch screen can support double-sided touch, one touch screen can be reduced, thereby saving the purchase and installation cost of one touch screen, but there is no existing technology in the market that can enable the touch screen to support double-sided touch.

[0040] The application provides a method for distinguishing touch directions of a double-sided touch screen comprising a touch module, and overcomes the technical problem that the touch screen in the prior art only supports single-sided touch and does not support double-sided touch. In the method for distinguishing touch directions, when the double-sided touch screen senses a touch operation, a touch signal is generated; the touch signal is identified to obtain an identification result; and based on the identification result and a preset self-capacitance algorithm, a touch direction of a touch sensing layer corresponding to the touch operation is obtained. By implementing the application, more flexible and changeable touch screen application scenarios can be supported, and in some application scenarios in which two touch screens need to be installed, only one double-sided touch screen needs to be installed to achieve the effect of the original two touch screens, thereby significantly reducing installation costs.

[0041] Reference Figure 1 In an embodiment of the application, a touch module is provided, which comprises:

[0042] an inner touch sensing layer 10 comprising an inner protective layer 103, an inner adhesive layer 102 and a first electrode layer 101 which are sequentially attached;

[0043] a middle adhesive layer 20;

[0044] an outer touch sensing layer 30 comprising an outer protective layer 303, an outer adhesive layer 302 and a second electrode layer 301 which are sequentially attached;

[0045] The first electrode layer 101 of the inner touch sensing layer 10, the middle adhesive layer 20 and the second electrode layer 301 of the outer touch sensing layer 30 are sequentially attached, and the inner touch sensing layer 10 and the outer touch sensing layer 30 are used to sense a touch signal, so that a control chip connected to the touch module identifies a touch direction of a touch operation corresponding to the touch signal based on the touch signal.

[0046] It should be noted that the first electrode layer 101 and the second electrode layer 301 can be regarded as touch sensors, and the material thereof can be ITO (Indium tin oxide, which has the advantages of transparency, high conductivity, high stability and high sensitivity) conductive material, nano-silver conductive material, metal mesh conductive material or copper ITO, copper nano-silver conductive material and the like, and the present embodiment does not limit the same.

[0047] In this embodiment, the first electrode layer 101 and the second electrode layer 301 are formed on the electrode-attached layer, i.e., the substrate, which can be a glass plate or a film plate. If the substrate is a film plate, the sensor is implemented by using a PET coating technology, and if the substrate is a glass plate, the sensor is implemented by using a GLASS coating technology. The first electrode layer 101 and the second electrode layer 301 can be formed on the substrate by subtractive process (forming a full-surface conductive layer by evaporation; forming a full-surface conductive layer by spraying / coating / flowing / immersing; forming a conductive pattern by chemical / laser etching method) or additive process (forming a patterned catalytic layer on the substrate; growing a conductive layer on the catalytic layer). The above process does not represent a limitation on the process that can be used in this embodiment, and in specific applications, the first electrode layer 101 and the second electrode layer 301 can also be made by other suitable processes.

[0048] In this embodiment, the inner adhesion layer 102, the middle adhesion layer 20 and the outer adhesion layer 302 include OCA (optical clear adhesive, which has the advantages of colorless transparency, high light transmittance and good adhesive strength). For electrodes made of ITO material, a single / double-sided blanking coating can be added to reduce the reflection difference between conductors and non-conductors and to reduce etching marks. For electrodes made of metal conductive material, a blackening layer can be added to reduce the reflection of metal electrodes and reduce metal grid line marks. In actual applications, optical coatings can be added according to actual needs, and this embodiment does not limit this.

[0049] In this embodiment, the inner protection layer 103 and the outer protection layer 303 are release films, which can be removed in actual use and a cover lens, i.e., protective glass or cover plate glass, can be added according to actual needs. The cover lens is also called strengthened optical glass, glass window, strengthened mobile phone lens, etc. It has the functions of impact resistance, scratch resistance, oil resistance, fingerprint resistance, and enhanced light transmittance. Its material can be PET, PI, Glass, PMMA, etc. It can also have a beautifying pattern. Adding a cover lens can protect the touch screen and print different colors, patterns, and markers to decorate and beautify the product. In this embodiment, the protective glass types include Corning 2320 Gorilla 3rd generation, Schott, Asahi 2nd generation, Dragontrail, Panda, etc.

[0050] In a specific implementation, the first electrode layer 101 and the second electrode layer 301 can be first manufactured, then the first electrode layer 101 and the inner bonding layer 102 are bonded, the second electrode layer 301 and the outer bonding layer 302 are bonded, the first electrode layer 101 bonded with the inner bonding layer 102 and the second electrode layer 301 bonded with the outer bonding layer 302 are respectively bonded on both sides of the middle bonding layer 20, and finally the inner protective layer 103 is bonded with the inner bonding layer 102 and the outer protective layer 303 is bonded with the outer bonding layer 302 to form a stacked structure as shown in FIG. 11. It should be noted that the bonding steps are not limited in the order, and in actual operation, the bonding steps can be adjusted as required without affecting the final product and function. Figure 1

[0051] In this embodiment, the positions of the first electrode layer 101 and the second electrode layer 301 can be interchanged, and the inner side and the outer side are not limited to the orientation of the touch module. Only for the convenience of distinction, it is indicated that the touch module in this embodiment has the function of touchable on both sides.

[0052] It can be understood that on the basis of the above structure, the touch module in this embodiment supports the touch operation triggered from the side where the inner protective layer 103 is located, and also supports the touch operation triggered from the side where the outer protective layer 303 is located, and can convert the touch operation into a touch signal and transmit it to the control chip connected with the touch module for processing to identify whether the trigger of the touch operation is from the inner side or the outer side.

[0053] As an example, the first electrode layer 101 includes a plurality of first sensing electrode units arranged in the same layer and independent of each other, and the second electrode layer 301 includes a plurality of second sensing electrode units arranged in the same layer and independent of each other.

[0054] It can be understood that the first electrode layer 101 and the second electrode layer 301 each include a plurality of groups of electrodes.

[0055] As an example, the first sensing electrode units are arranged at equal intervals along a first direction, the second sensing electrode units are arranged at equal intervals along a second direction, and the first direction and the second direction are perpendicular to each other.

[0056] It can be understood that the plane where the first electrode layer 101 is located and the plane where the second electrode layer 301 is located are parallel to each other, a plane rectangular coordinate system is established on the plane, the first direction can be understood as the axial extension direction of the X-axis of the plane, and the second direction can be understood as the axial extension direction of the Y-axis of the plane.

[0057] ​As an example, the first sensing electrode units and the second sensing electrode units are arranged staggeredly in a third direction, and form an array structure, the third direction being perpendicular to the plane in which the intermediate bonding layer 20 is located.

[0058] It can be understood that the plane in which the intermediate bonding layer 20 is located is also parallel to the plane in which the first electrode layer 101 is located and the plane in which the second electrode layer 301 is located. If the plane is flush with the horizontal plane, the array structure can be observed from the top-down view or the bottom-up view in the vertical direction.

[0059] As an example, the proportion of the overlapping area and the non-overlapping area of the first sensing electrode units and the second sensing electrode units in the third direction is a preset value.

[0060] It should be noted that the overlapping area refers to the area covered by the first electrode sensing unit and the second electrode sensing unit from the vertical direction. In this embodiment, the preset value is set to 0.5. According to the actual situation, the preset value can be preferably adjusted to the range of 0.25-4, or can be relaxed to 0.1-10.

[0061] In this embodiment, two array structure design schemes are provided. Referring to Figure 2 and Figure 3 , Figure 2 and Figure 3 are array design diagrams of each sensing electrode unit in the first electrode layer 101 and the second electrode layer 301 of the touch module in this embodiment, Figure 2 and Figure 3 the pattern design is not limited by the preset parameters and preset values in the foregoing.

[0062] From Figure 2 , it can be seen that the first sensing electrode units arranged in the X-axis direction (i.e., horizontally arranged) and the second sensing electrode units arranged in the Y-axis direction (i.e., vertically arranged) are both strip-shaped rectangular electrode patterns spaced from each other, and the electrode width and the electrode spacing are equal.

[0063] From Figure 3 , it can be seen that the first sensing electrode units arranged in the X-axis direction (i.e., horizontally arranged) and the second sensing electrode units arranged in the Y-axis direction (i.e., vertically arranged) are both electrode patterns composed of multiple diamonds and elongated rectangles for connecting the diamonds, and the electrode overlapping area is much smaller than the non-overlapping area.

[0064] In addition, when using a metal mesh material as the material of the above-mentioned electrode pattern, due to the small proportion of the wire area to the opening area, the double-sided touch signal recognition can be better realized.

[0065] As an example, the first sensing electrode units are connected by wires arranged along the first direction, and the second sensing electrode units are connected by wires arranged along the second direction.

[0066] It can be understood that each sensing electrode unit needs to be connected by wires to enable the current to pass through each sensing electrode smoothly, and finally connected to the preset binding position, such as an external control chip or a mainboard where a controller is located, etc.

[0067] As an example, the inner touch sensing layer 10 and the outer touch sensing layer 30 are both capacitive touch sensing layers.

[0068] It should be noted that in the embodiment, a self-capacitance and mutual-capacitance combined mode is used to perform product surface electric field scanning, to realize the determination of the facing of the touch and the accurate identification of the touch position.

[0069] The embodiment provides a touch module, which overcomes the technical problem that the touch screen in the prior art only supports single-side touch and does not support double-side touch. The touch module provided by the embodiment comprises an inner touch sensing layer, an intermediate bonding layer and an outer touch sensing layer. The inner touch sensing layer comprises an inner protective layer, an inner bonding layer and a first electrode layer which are sequentially bonded. The outer touch sensing layer comprises an outer protective layer, an outer bonding layer and a second electrode layer which are sequentially bonded. The first electrode layer of the inner touch sensing layer, the intermediate bonding layer and the second electrode layer of the outer touch sensing layer are sequentially bonded. The inner touch sensing layer and the outer touch sensing layer are used for sensing a touch signal, so that a control chip externally connected to the touch module identifies the facing of a touch operation corresponding to the touch signal based on the touch signal. Based on the touch module provided by the embodiment, a double-side touch screen can be developed, which can support more flexible and variable touch screen application scenarios.

[0070] An embodiment of the present application provides a double-side touch screen, which comprises a control chip and a touch module as described above, and the control chip is electrically connected to the touch module.

[0071] It should be understood that the double-side touch screen is installed in an image display device to work as an input device, and the image display device can be a transparent organic light-emitting diode (OLED) and a transparent Mini LED display screen, etc. The embodiment is not limited in this regard. The control chip is used to receive a touch signal from the touch module, analyze the touch signal, and then issue a corresponding control command to make the external touch operation corresponding to the touch signal effective.

[0072] Specifically, the double-sided touch screen can be applied to the following scenario: the double-sided touch screen is used in a transparent Mini LED display screen of a restaurant window, a product promotion video is played when there is no touch; when a potential customer outside the window wants to know about the product, the outer side is touched to display a recommended picture of the product of interest; when a customer inside the window wants to place an order, the inner side is touched to display a menu picture.

[0073] In the embodiment, a double-sided touch screen is provided, and a specific application scenario of the double-sided touch screen is given. Compared with the prior art, in which two touch screens are needed to meet the operation requirements in the scenario, only one double-sided touch screen provided in the embodiment is needed to meet the same requirements, thereby significantly saving the cost of the user.

[0074] With reference to Figure 4 , based on the touch module and the double-sided touch screen shown in FIG. 1, an embodiment of the present application provides a method for distinguishing a touch direction, which is applied to the double-sided touch screen and includes the following steps: Figure 1

[0075] Step S10: When the double-sided touch screen senses a touch operation, a touch signal is generated.

[0076] Step S20: The touch signal is identified to obtain an identification result.

[0077] Step S30: Based on the identification result and a preset self-capacitance algorithm, a touch direction of a touch sensing layer corresponding to the touch operation is obtained.

[0078] It should be noted that the signals that can be transmitted by the first electrode layer 101 and the second electrode layer 301 in the double-sided touch screen include: a. a driving pulse signal; b. a sensing pulse signal; and c. a ground signal.

[0079] The logic process of identifying, by using the preset self-capacitance algorithm, whether a touch position occurs on the inner side corresponding to the first electrode layer 101 or the outer side corresponding to the second electrode layer 301 is as follows:

[0080] Driving pulse signals are sequentially provided to each sensing electrode unit in the first electrode layer 101, and a ground signal is provided to all sensing electrode units in the second electrode layer 301. At this time, when a touch operation occurs, the change in the capacitance data measured on the inner side corresponding to the first electrode layer 101 is much higher than the change in the capacitance data measured on the outer side corresponding to the second electrode layer 301 (because part of the signal is shielded by the ground signal when the outer side corresponding to the second electrode layer 301 is touched).

[0081] ​In contrast, the driving pulse signal is provided to each sensing electrode unit of the second electrode layer 301 in sequence, and a grounding signal is provided to all sensing electrode units of the first electrode layer 101, at this time, when a touch operation occurs, the capacitance data change measured by the second electrode layer 301 corresponding to the outer touch is much higher than the capacitance data measured by the first electrode layer 101 corresponding to the inner touch (because part of the signal is shielded by the grounding signal when the inner touch corresponding to the first electrode layer 101).

[0082] Therefore, it can be identified whether the touch operation occurs in the inner touch sensing layer 10 corresponding to the first electrode layer 101, or the outer touch sensing layer 30 corresponding to the second electrode layer 301, or the touch operation occurs on both sides.

[0083] Further, the embodiment can also provide the driving pulse signal to one of the first electrode layer 101 or the second electrode layer 301, and the other layer monitors the generated sensing pulse signal, based on the mutual capacitance principle in the prior art, to accurately calculate the touch coordinates and further obtain the accurate position of the touch operation.

[0084] The above logical process is repeated to realize the recognition of the driving orientation and the driving position based on the double-sided touch screen.

[0085] In the embodiment, a method for distinguishing the touch orientation of the double-sided touch screen including the touch module is provided, which overcomes the technical problem that the touch screen in the prior art only supports single-sided touch and does not support double-sided touch. In the method for distinguishing the touch orientation, when the double-sided touch screen senses a touch operation, a touch signal is generated; the touch signal is identified to obtain an identification result; and based on the identification result and a preset self-capacitance algorithm, the orientation of the touch sensing layer corresponding to the touch operation is obtained. The embodiment provides a rigorous judgment logic for distinguishing the touch orientation, can realize the recognition of the driving orientation and the driving position based on the double-sided touch screen, realizes that the double-sided touch screen can be touched on both sides, and can identify which side the touch occurs; and based on the identification result, a specific function is developed, for example, setting a touch priority (inner touch priority, or outer touch priority, or a racing mode, or partitioning the screen for different users, etc.), which can support more flexible and variable touch screen application scenarios.

[0086] Reference Figure 5 , Figure 5 The internal structure of the double-sided touch screen involved in the method for distinguishing the touch orientation of the embodiment of the application is shown in the figure.

[0087] As Figure 5As shown, the dual-sided touchscreen may include: a processor 1001, which may be a control chip as described above, or a central processing unit (CPU); a communication bus 1002; a user interface 1003; a network interface 1004; and a memory 1005.
