Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a touch display module according to a first embodiment of the present application. The touch display module 1 of the present application includes a touch module 10 and a display module 20, and the touch module 10 is disposed on the display module 20. The touch module 10 and the display module 20 may be combined by a full-lamination adhesive mode or a frame-lamination adhesive mode, and fig. 1 illustrates that the touch module 10 and the display module 20 are combined by a full-lamination adhesive mode.

The touch module 10 includes a cover glass 11 and a heat generating layer 12.

In this embodiment, the heating layer 12 is disposed on a side of the protective glass 11 near the display module 20, and the heating layer 12 is used for removing mist of the touch display module 1 by generating heat. When the touch display module 1 is in a low temperature, plum rain season or an environment facing an air conditioner, the display module 20 is in operation and slightly heats, that is, the side of the cover glass 11 close to the display module 20 and the side far away from the display module 20 generate a temperature difference, and at this time, the surface of the cover glass 11 is fogged due to the temperature difference, so that the display and the touch effect of the touch display module 1 are affected. The heating layer 12 is arranged on one side of the protective glass 11, which is close to the display module 20, and can generate heat, so that the temperature of one side of the protective glass 11, which is close to the display module 20, is consistent with that of one side of the protective glass, which is far away from the display module 20, and the protective glass 11 cannot be fogged due to temperature difference between two sides. Or the heating layer 12 generates heat, and the heat is transferred to the protective glass 11, so that fog on the surface of the protective glass 11 is evaporated, and the operation sensitivity of the touch display module 1 is ensured.

Fig. 2 is a schematic structural diagram of a touch display module according to a second embodiment of the present application. The touch display module 1 includes a display area 111 and a non-display area 112. The non-display region 112 is disposed around the display region 111, and at least a portion of the heat generating layer 12 is located in the display region 111.

In this embodiment, the heat generating layer 12 may cover the whole display area 111, so as to ensure the display definition of the display area 111 and the touch sensitivity in the touch display module 1. And the heating layer 12 may be partially disposed in the non-display area 112, so as to avoid a temperature difference between the non-display area 112 and the display area 111, and avoid the display effect being affected by the temperature difference when the display area 111 is close to the edge of the non-display area 112. In other embodiments, the heat generating layer 12 may be disposed only in the non-display area 112 to reduce the cost, and the location where the heat generating layer 12 is disposed is not limited in the present application.

Alternatively, as shown in fig. 1, a heat generating layer 12 is coated on a side surface of the cover glass 11 near the display module.

The touch module 10 and the display module 20 can be combined by a full-lamination adhesive mode, and the protective glass 11 is fully laminated on the display module 20 in the full-lamination adhesive mode. Therefore, the heat generating layer 12 can be directly coated on the surface of the cover glass 11, and a material layer with a larger thickness is not required to be arranged between the cover glass 11 and the display module 20 to bear the heat generating layer 12. Coating the heating layer 12 on the surface of the protective glass 11 instead of being provided with a material layer with a larger thickness can ensure that the heating layer 12 does not affect the display content of the display module 20 to the greatest extent, and simultaneously reduce the thickness of the touch display module 1.

Optionally, the touch module 10 includes an optical substrate 13.

When the touch module 10 and the display module 20 are combined by the frame bonding and gluing method, as shown in fig. 3, fig. 3 is a schematic structural diagram of a third embodiment of the touch display module provided in the present application. Since the protective glass 11 and the display module 20 are bonded by the frame bonding and gluing method, that is, a cavity exists between the protective glass 11 and the display module 20, if the heating layer 12 is directly coated on the side surface of the protective glass 11, the heat generated by the heating layer 12 will preferentially enter the cavity, so that the heating layer 12 cannot eliminate the temperature difference of the surface of the protective glass 11, and the excessive heat received in the cavity may cause the cavity to bulge, thereby affecting the safety of the touch display module 1.

Therefore, in the present embodiment, the heat generating layer 12 is first coated on the optical substrate 13, and then the optical substrate 13 is disposed on the side of the cover glass 11 close to the display module 20, and the heat generating layer 12 is located between the optical substrate 13 and the cover glass 11. So that the heat emitted from the heat generating layer 12 enters into the cover glass 11 and the optical substrate 13, and the temperature difference of the surface of the cover glass 11 is eliminated, thereby avoiding fogging on the surface of the cover glass 11. Meanwhile, heat passes through the optical substrate 13 and then reaches the display module 20 through the frame adhesive layer, so that the cavity is wrapped in an environment with proper temperature, and the cavity is prevented from swelling; and can prevent mist, bacteria, etc. generated by temperature difference in the cavity, and leave unremovable mildew on the display module 20, which affects the display of the touch display module 1.

The optical substrate 13 may be colorless optical glass, and has the characteristics of light absorption and high transmittance, and can conduct heat generated by the heating layer 12 and simultaneously avoid shielding the display content of the display module 20 to the greatest extent.

In other embodiments, if the touch module 10 or the display module 20 includes other component layers, the heating layer 12 may also be coated on the other component layers, and the application is not limited to the coating position of the heating layer 12.

Optionally, the heat-generating layer 12 includes at least one graphene thin film layer.

The graphene film has excellent heat conduction performance, can conduct electricity and transmit light, has high flexibility, and is suitable for being applied to the heating layer 12. In this embodiment, the surface of the protective glass 11 near the side of the display module 20 may be coated with a graphene film layer, which has excellent heat conduction performance, and can transfer heat to the protective glass 11 and the display module 20 to remove mist on the protective glass 11.

In other embodiments, the user may select the number of layers of the graphene film layer according to the actual requirement or the arrangement of each structural layer of the touch display module 1, for example, two layers, four layers or five layers, etc., which is not limited in this application.

Wherein, the light transmittance of the graphene film layer is more than 80%. That is, when the graphene film layer is disposed in the display area 111 of the touch display module 1, the content displayed by the display module 20 is not affected. The defogging of the touch display module 1 is performed, the working performance of the touch display module 1 is not affected, and the use experience of a user on the touch display module 1 is improved.

Optionally, the touch display module 1 includes a temperature and humidity sensor (not shown).

The temperature and humidity sensor can be used for detecting the ambient temperature and the ambient humidity of the touch display module 1, so that the heating layer 12 is controlled to generate heat to eliminate the temperature difference of the protective glass 11, and the display is prevented from being influenced by fog on the surface of the protective glass 11.

Optionally, the touch display module 1 includes a control module (not shown).

The control module is connected with the temperature and humidity sensor and the heating layer 12, and is used for controlling the heating layer 12 to generate heat according to the ambient temperature and the ambient humidity detected by the temperature and humidity sensor.

In this embodiment, when the touch display module 1 is in an environment with a relatively high humidity, the temperature and humidity sensor transmits the detected ambient humidity to the control module, and the control module determines that the ambient humidity is too high, so as to improve the heat generating efficiency of the heating layer 12. The heat generated by the heating layer 12 is transferred to the protective glass 11, and the water droplets on the surface of the protective glass 11 are evaporated, so that the water droplets are prevented from adhering to the surface of the protective glass 11 due to the temperature difference between the touch display module 1 and the external environment, and the display of the touch display module 1 is prevented from being influenced.

In other embodiments, the temperature and humidity sensor transmits the detected ambient humidity to the control module, and the control module determines that the ambient humidity is appropriate, that is, the droplets suspended in the environment are insufficient to fog on the surface of the protective glass 11, and the droplets are evaporated without generating heat by the heating layer 12. The control module then controls the heat generating layer 12 to reduce the heat generation, thereby reducing the energy consumption of the heat generating layer 12.

It can be understood that the temperature and humidity sensor transmits the detected ambient humidity and ambient temperature to the control module after detecting the ambient humidity and ambient temperature of the touch display module 1. Wherein, the control module may store a preset temperature and a preset humidity in advance (the preset temperature and the preset humidity may be set by a user according to experience), and when the control module determines that the environmental humidity is greater than the preset humidity, it determines that the environmental humidity is too high at this time, and controls the heating layer 12 to increase to generate heat, so as to evaporate the water droplets on the surface of the protective glass 11. When the control module judges that the ambient humidity is equal to or less than the preset humidity, the control module determines that the ambient humidity is proper or dry at the moment, controls the heating layer 12 to reduce the heat generation and reduces the energy consumption of the heating layer 12. The same is true for the judgment of the ambient temperature detected by the temperature and humidity sensor.

Optionally, the touch module 10 includes a positive lead 121 and a negative lead 122.

As shown in fig. 2, the positive electrode lead 121 and the negative electrode lead 122 may be disposed on both sides of the heat generating layer 12, respectively. And the positive electrode lead 121 and the negative electrode lead 122 are connected with the control module, and after the control module judges the environment where the touch display module 1 is located according to the temperature and humidity sensor, the control module controls the voltages at two ends of the positive electrode lead 121 and the negative electrode lead 122, so as to control the heat generated by the heating layer 12. In this embodiment, the positive electrode lead 121 and the negative electrode lead 122 may be prepared by using silver paste, and when different voltages are applied to the silver paste leads, the silver paste leads emit different amounts of heat. And positive electrode lead 121 and negative electrode lead 122 set up in the both sides of layer 12 generates heat, and layer 12 generates heat including the fabulous graphite alkene thin film layer of heat conductivility, after graphite alkene thin film layer received the heat that positive and negative electrode lead produced, owing to have heat conductivility, heat transfer all positions of graphite alkene thin film layer, graphite alkene thin film layer will heat transfer to on cover glass 11 and the display module assembly 20 simultaneously, gets rid of the fog on the touch-control display module assembly 1.

In other embodiments, the positive electrode lead 121 and the negative electrode lead 122 may be made of a metal conductive film, and the materials for manufacturing the positive electrode lead 121 and the negative electrode lead 122 are not limited in this application.

Optionally, as shown in fig. 1, the touch display module includes a heat conductive layer 30.

The heat conducting layer 30 is disposed at a distance from the heat generating layer 12, and is configured to receive heat emitted by the heat generating layer 12 and transfer the heat to the display module 20.

Since the display module 20 is generally composed of a back plate, an LED lamp, a circuit board, etc., there is no heat conduction property. Therefore, in the present embodiment, a heat conducting layer 30 is disposed between the heating layer 12 and the display module 20, and the heat conducting layer 30 is fully covered on the display module 20 for transferring the heat energy generated by the heating layer 12 to the display module 20, so as to remove the mist, bacteria, etc. possibly existing at the joint of the display module 20 and the touch module 10. The working performance of the display module 20 is ensured, and the use experience of a user on the touch display module 1 is improved.

In summary, the touch display module 1 of the present application includes a touch module 10, a display module 20, a temperature and humidity sensor, a control module and a heat conducting layer 30. The touch module 10 includes a protective glass 11 and a heating layer 12, and when the touch module 10 and the display module 20 are bonded by a frame bonding and gluing mode, the touch module 10 further includes an optical substrate 13. The temperature and humidity sensor detects the ambient temperature and the ambient humidity of the touch display module 1, and the control module judges the magnitude relation between the ambient temperature and the ambient humidity at the moment and a preset value, so that the voltages applied to the positive electrode lead 121 and the negative electrode lead 122 are controlled, and the heating layer 12 generates different heat to remove mist, bacteria and the like on the surfaces of the protective glass 11 and the display module 20. The condensation of fog or bacteria breeding on the touch display module 1 due to the change of the ambient temperature or humidity of the touch display module 1 is avoided, so that the working performance of the touch display module 1 is affected.

The application also provides a display (not shown), comprising the touch display module 1. Among other things, the present application provides a display including, but not limited to, devices with display capabilities that can be applied to cell phones, tablet computers, laptops, or televisions.

The following steps are the working steps of the touch display module 1 in the display:

when the display is turned on, the display module 20 displays content, and the temperature and humidity sensor detects the ambient temperature and the ambient humidity of the display in real time and transmits the detected data to the control module. The control module compares the environmental temperature and the environmental humidity at this time with preset values, and controls voltages at both ends of the positive electrode lead 121 and the negative electrode lead 122 according to the comparison result, thereby changing the heat emitted from the heat generating layer 12. For example, when the control module determines that the ambient humidity is greater than the preset humidity, the voltage across the positive electrode lead 121 and the negative electrode lead 122 is increased, so that the heating layer 12 emits more heat, and the droplets represented by the cover glass 11 and the display module 20 are evaporated, so that the droplets are prevented from adhering to form a fog surface, and the display is prevented from being affected.

When the display is turned off, the display module 20 is turned off, but small water drops in the environment where the display is located may still adhere to the surface of the cover glass 11 to form a fog surface, or enter the joint of the display module 20 and the touch module 10, so that the surface of the display module 20 forms a fog surface or bacteria grow, thereby affecting the working performance of the touch display module 1. Therefore, the temperature and humidity sensor can periodically detect the ambient temperature and the ambient humidity of the display, and the control module controls the heat emitted by the heating layer 12 according to the data transmitted by the temperature and humidity sensor. The temperature and humidity sensor periodically detects the environment, and the control module periodically changes the heat emitted by the heating layer 12 instead of real-time change, so that the energy consumption of the heating layer 12 is reduced while the display is prevented from adhering mist.

The foregoing description is only of embodiments of the present application, and is not intended to limit the scope of the patent application, and all equivalent structures or equivalent processes using the descriptions and the contents of the present application or other related technical fields are included in the scope of the patent application.
