Description

Technical Field

[0001] This application relates to the field of displays, and more particularly to a display module and a display device. Background Technology

[0002] As monitors become more widely used in daily life, people have higher and higher requirements for them at home. Specifically, they demand higher refresh rates, resolutions, and sizes. The larger the monitor, the higher the refresh rate and resolution, the better the display effect and the more realistic the picture.

[0003] In dimly lit indoor environments or at night when other lights are off, the monitor becomes the brightest light source, attracting insects to fly to and land on the display panel, thus reducing the user's viewing experience. In addition, due to the large size and high installation position of the monitor, it is difficult to effectively repel insects.

[0004] Therefore, how to repel insects attached to the display panel and ensure the user's viewing experience has become an urgent problem to be solved in this field. Summary of the Invention

[0005] This application discloses a display module and a display device, the purpose of which is to use electric current to drive away mosquitoes attached to the display panel and ensure the user's viewing experience.

[0006] This application discloses a display module, which includes a display panel and a film. The film includes a substrate and a conductive element. The substrate is disposed on one side of the light-emitting surface of the display panel, and the conductive element is laid in the substrate. When the conductive element is in a first state, the current passing through the conductive element is a preset current. When the conductive element is in a second state, the current passing through the conductive element is greater than the preset current.

[0007] Optionally, the preset current ranges from 0 mA to 4 mA.

[0008] Optionally, the substrate is made of a light-transmitting insulating material, and the thickness of the substrate is between 0.1 mm and 0.3 mm. The conductive element is sheet-shaped, and the thickness of the conductive element is less than the thickness of the substrate. There are multiple conductive elements, and the multiple conductive elements are arranged at intervals on the substrate.

[0009] Optionally, the substrate is further provided with a sensor and a current controller. The conductive element is electrically connected to the sensor, and the sensor is electrically connected to the current controller. When the sensor detects that the conductive element is in a first state, the sensor transmits a detection signal to the current controller, and the current controller controls the current to be maintained at the preset current. When the sensor detects that the conductive element is in a second state, the sensor transmits a detection signal to the current controller, and the current controller controls the current through the conductive element to be greater than the preset current and less than 10 mA.

[0010] Optionally, the first state is defined as the resistance of the conductive element being in an initial resistance state, and the second state is defined as the resistance of the conductive element being greater than the initial resistance state. The sensor is a resistance sensor.

[0011] Optionally, the first state is when the surface pressure of the conductive element is 0, and the second state is when the surface pressure of the conductive element is greater than 0. The sensor is a pressure sensor.

[0012] Optionally, when the sensor detects that the conductive element is in the second state for a first preset time, the sensor transmits the detection signal to the current controller, and the current controller controls the current through the conductive element to be greater than the preset current. After a second preset time, the current controller controls the current through the conductive element to be reduced to the preset current. The first preset time is greater than 30 seconds, and the second preset time is greater than 5 seconds and less than 10 seconds.

[0013] Optionally, the display module further includes a sweeping and blowing device, which includes a housing, a guide rod, a lead screw, a motor, a connector, a fan, and a transmission box. The housing is installed on one side of the display panel. The guide rod and the lead screw are connected to the side of the housing near the display panel, and the guide rod and the lead screw extend in the same direction as the side of the display panel. The motor and the transmission box are both located on the side of the housing away from the display panel. The motor is connected to the transmission box, and the lead screw is connected to the transmission box. The motor drives the transmission box, and the transmission box drives the lead screw to rotate axially. The connector includes a first connecting part and a second connecting part. The first connecting part is connected to the second connecting part. The first connecting part is sleeved on the guide rod, and the second connecting part is sleeved on the lead screw. The side of the second connecting part away from the first connecting part is connected to the fan, which is used to sweep and blow the display panel. The first connecting part and the second connecting part move simultaneously along the extension direction of the lead screw as the lead screw rotates.

[0014] Optionally, when the sensor detects that the conductive component is in the first state, the sweeping and blowing device performs a sweeping and blowing once within a preset time interval; when the sensor detects that the conductive component is in the second state, and after a third preset time, the sweeping and blowing device performs a sweeping and blowing once, and the third preset time is greater than the second preset time.

[0015] This application also discloses a display device, including a rear housing, and the display device further includes the aforementioned display module, which is installed inside the rear housing.

[0016] This application involves setting a film on the light-emitting surface of a display panel, with a conductive element built into the film. The film supplies power to the conductive element via an external power source. When no insects are attached to the surface of the display panel, the conductive element is in a first state, with a preset current flowing through it. At this time, the conductive element maintains a relatively low current flow, posing no health risk to humans. When an insect lands on the film, it changes the conductive element from the first state to a second state. In this second state, the current flowing through the conductive element is greater than the preset current, i.e., it changes from a low current state to a high current state, creating an electric shock to the insect and thus repelling it. In this way, insects attached to the display panel can be repelled by electric shock without human intervention, which is simple, convenient, and further ensures the user's viewing experience.

Detailed Implementation

[0025] The present application will now be described in detail with reference to the accompanying drawings and optional embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Figure 1 This is a schematic diagram of the first embodiment of the display module of this application. Figure 2 This is a schematic diagram of the diaphragm in the first embodiment of the display module of this application, as shown below. Figure 1 and Figure 2 As shown, this application discloses a display module 100, which includes a display panel 110 and a film 120. The film 120 includes a substrate 121 and a conductive element 122. The substrate 121 is disposed on one side of the light-emitting surface of the display panel 110, and the conductive element 122 is disposed within the substrate 121. When the conductive element 122 is in a first state, the current passing through the conductive element 122 is a preset current. When the conductive element 122 is in a second state, the current passing through the conductive element 122 is greater than the preset current.

[0027] This application provides a film 120 on the light-emitting surface of the display panel 110, and the film 120 contains a conductive element 122. The film 120 supplies power to the conductive element 122 by connecting to an external power source. When there are no insects attached to the surface of the display panel 110, the conductive element 122 is in a first state, and the current passing through the conductive element 122 is a preset current. At this time, the conductive element 122 maintains a state with a small current, which will not cause any health effects on the human body. When an insect flies onto the film 120, it will change the conductive element 122 from the first state to the second state. At this time, the current passing through the conductive element 122 is greater than the preset current, that is, it changes from a small current state to a large current state, which will generate an electric shock to the insect, thereby achieving the purpose of repelling the insect. In this way, insects attached to the display panel 110 can be repelled by electric shock without human intervention, which is simple and convenient, and further ensures the user's viewing experience.

[0028] It should be noted that in this application, the diaphragm 120 can be powered independently by an external power supply to the conductive element 122 inside the diaphragm 120. This avoids sharing a power supply system with the display panel 110, which could lead to unstable power supply to the display panel 110, thus ensuring the display effect of the display panel 110. Furthermore, using an external power supply for independent power supply also makes it easier to install and replace the diaphragm 120 separately. In addition, the first state in this application refers to the state of the conductive element 122 when there are no insects attached to the surface of the display panel 110 (i.e., the light-emitting surface of the display panel 110 after the diaphragm 120 is installed), and the second state refers to the state of the conductive element 122 when there are insects attached to the surface of the display panel 110. The state of the conductive element 122 can be understood as a change in the properties of the conductive element 122, such as a change in the resistance of the conductive element 122, or a change in the conductive element 122 caused by external forces, such as a change in the force acting on the surface of the conductive element 122.

[0029] Since the current that can effectively repel mosquitoes is generally above 5 mA, the current range of this application is preset to be between 0 mA and 4 mA. When there are no mosquitoes attached to the surface of the display panel 110, the current passing through the conductive element 122 is less than the current that can directly repel mosquitoes. This ensures that the conductive element 122 is kept in a state with a small current, which will not cause any health effects on the human body. In addition, when it is not necessary to repel mosquitoes, the energy consumption generated by the membrane 120 can be effectively reduced, saving electricity.

[0030] Specifically, the substrate 121 is made of a light-transmitting insulating material, and the thickness of the substrate 121 is between 0.1 mm and 0.3 mm. The conductive element 122 is sheet-shaped, and the thickness of the conductive element 122 is less than the thickness of the substrate 121. There are multiple conductive elements 122, and the multiple conductive elements 122 are arranged at intervals on the substrate 121.

[0031] In this application, the substrate 121 of the diaphragm 120 is made of a light-transmitting insulating material, such as highly light-transmitting plastic. The conductive component 122 can also be made of a light-transmitting material to reduce the obstruction of display light, such as ITO (Indium Tin Oxide). This ensures that after the diaphragm 120 is installed on the display panel 110, it will not obstruct the light emitted by the display panel 110 too much, thus ensuring the display effect of the display panel 110 to a certain extent. At the same time, when the diaphragm 120 is powered on, there will be no electrical conduction between the diaphragm 120 and the display panel 110, which can avoid short circuits and other phenomena in the electronic components of the display panel 110, thus ensuring the normal display of the display panel 110.

[0032] Furthermore, since the diaphragm 120 is additionally disposed on the light-emitting surface of the display panel 110, in order to ensure that the diaphragm 120 does not affect the overall thickness of the display panel 110 after installation, this application has also designed the thickness of the diaphragm 120, setting the thickness range of the diaphragm 120 to between 0.1 mm and 0.3 mm. For example, when the thickness of the diaphragm 120 is 0.2 mm, the thickness of the diaphragm 120 is approximately the same as the thickness of other optical diaphragms 120 in the optical module, and will not have a significant impact on the overall thickness of the display panel 110. This is beneficial to achieving the mosquito-repellent effect while making the display panel 110 thinner and lighter.

[0033] The conductive element 122 in this application is sheet-shaped and can be made of conductive metal material, such as copper. The sheet-shaped conductive element 122 has a certain surface area, which is conducive to the contact between mosquitoes and the conductive element 122, so that the conductive element 122 can shock and repel mosquitoes. Arranging multiple conductive elements 122 at intervals on the film 120 to form an integral laying on the film 120 further increases the contact area between the conductive element 122 and mosquitoes, thereby increasing the probability of mosquitoes landing on the conductive element 122. This allows the conductive element 122 to effectively repel mosquitoes while ensuring that the display panel 110 can have sufficient light transmission without significantly obstructing the display panel 110, thus ensuring the normal display of the display panel 110.

[0034] Of course, the conductive element 122 can also be filamentous. For example, the conductive element 122 is a copper wire. The copper wire is embedded in the substrate 121 to form a film 120. After being energized, it can also repel mosquitoes. This application does not specifically limit the shape of the conductive element 122, but only uses the example of the conductive element 122 being sheet-shaped.

[0035] When installing the conductive element 122, a receiving groove can be first opened on the substrate 121 of the film 120, and then the conductive element 122 can be embedded into the receiving groove, so that the surface of the conductive element 122 away from the display panel 110 is flush with the surface of the substrate 121 away from the display panel 110, so that part of the conductive element 122 is exposed on the substrate 121, making it easier for mosquitoes to come into contact with the conductive element 122, and making it easier for mosquitoes to land on the conductive element 122. When the conductive element 122 is energized with a current greater than the preset current, it can effectively repel mosquitoes.

[0036] Furthermore, such as Figure 2As shown, a sensor 123 and a current controller 124 are also provided on the substrate 121. The conductive element 122 is electrically connected to the sensor 123, and the sensor 123 is electrically connected to the current controller 124. When the sensor 123 detects that the conductive element 122 is in a first state, the sensor 123 transmits the detection signal to the current controller 124, and the current controller 124 controls the current to be maintained at a preset current. When the sensor 123 detects that the conductive element 122 is in a second state, the sensor 123 transmits the detection signal to the current controller 124, and the current controller 124 controls the current through the conductive element 122 to be greater than the preset current and less than 10 mA.

[0037] In this application, a sensor 123 is used to detect the state changes of the conductive element 122, and a current controller 124 is used to control the current through the conductive element 122. When there are no mosquitoes attached to the surface of the display panel 110, the sensor 123 detects that the conductive element 122 is in the first state. The sensor 123 transmits the detection signal to the current controller 124. After processing the signal, the current controller 124 controls the current through the conductive element 122 to a preset current. At this time, the conductive element 122 is maintained in a state with a small current, which will not cause any health effects on the human body. In addition, when it is not necessary to repel mosquitoes, the energy consumption generated by the diaphragm 120 can be effectively reduced, saving electricity.

[0038] When a mosquito lands on the diaphragm 120, the sensor 123 detects that the conductive element 122 has changed from the first state to the second state. At this time, the sensor 123 transmits the detection signal to the current controller 124. After processing the signal, the current controller 124 controls the current through the conductive element 122 to be greater than the preset current, that is, from a smaller current state to a larger current state, to generate an electric shock to the mosquito, thereby achieving the purpose of repelling the mosquito. In this way, mosquitoes attached to the display panel 110 can be repelled by electric shock without human intervention, which is simple and convenient and further ensures the user's viewing experience. The current controller 124 controls the current through the conductive element 122 to below 10 mA to ensure that a safe current is provided when the user accidentally touches the screen, so as not to cause harm to the human body, not to affect the user's health, and to improve the safety of use.

[0039] In this embodiment, the first state is when the resistance of the conductive element 122 is in the initial resistance state, and the second state is when the resistance of the conductive element 122 is greater than the initial resistance state. The sensor 123 is a resistance sensor 123.

[0040] Since when a mosquito lands on the conductive element 122, the resistance of the conductive element 122 increases, changing the state of the conductive element 122 and reducing the current passing through the conductive element 122, in this embodiment, a resistance sensor 123 is used to detect the change in resistance of the conductive element 122 to determine whether there is a mosquito landed on the display panel 110.

[0041] The actual working process is as follows: When the resistance sensor 123 detects that the resistance of the conductive element 122 is equal to the resistance of the conductive element 122 itself, it indicates that no mosquitoes are on the conductive element 122. The resistance sensor 123 transmits the detection signal to the current controller 124. After processing the signal, the current controller 124 controls the current through the conductive element 122 to a preset current. At this time, the conductive element 122 is maintained in a state with a small current, for example, the current through the conductive element 122 is maintained at 1 mA. This will not cause any health effects on the human body. In addition, when it is not necessary to repel mosquitoes, the energy consumption generated by the diaphragm 120 can be effectively reduced, saving electricity.

[0042] When a mosquito lands on the diaphragm 120, the resistance of the conductive element 122 increases. The sensor 123 detects that the resistance of the conductive element 122 is greater than its initial resistance. At this time, the resistance sensor 123 transmits the detection signal to the current controller 124. After processing the signal, the current controller 124 controls the current through the conductive element 122 to be greater than the preset current, that is, changes from a small current state to a large current state, such as a current of 5 mA to generate an electric shock to the mosquito, so as to achieve the purpose of repelling the mosquito. In this way, the mosquito attached to the display panel 110 can be repelled by electric shock without human intervention, which is simple and convenient and further ensures the user's viewing experience.

[0043] Figure 3 This is a schematic diagram of the diaphragm in the second embodiment of the display module of this application, as shown below. Figure 3 As shown, Figure 3 The illustrated embodiment is based on Figure 2 The improvement is that when the surface pressure of the conductive element 122 is 0, it is in the first state; when the surface pressure of the conductive element 122 is greater than 0, it is in the second state; and the sensor 123 is a pressure sensor 123.

[0044] Since the surface pressure of the conductive element 122 is 0 when no mosquitoes are present, but when mosquitoes are present on the conductive element 122, they will generate a certain pressure on the conductive element 122 due to contact, and the surface pressure of the conductive element 122 will be greater than 0; therefore, in this embodiment, the sensor 123 is a pressure sensor 123. The pressure sensor 123 is used to detect the pressure change on the surface of the conductive element 122 to determine whether there are mosquitoes on the display panel 110. The pressure change on the surface of the conductive element 122 is used as the switching judgment between the first state and the second state of the conductive element 122.

[0045] The actual working process is as follows: When the pressure sensor 123 detects that the surface pressure of the conductive element 122 is 0, it means that no mosquitoes are staying on the conductive element 122. The pressure sensor 123 transmits the detection signal to the current controller 124. After processing the signal, the current controller 124 controls the current through the conductive element 122 to a preset current. At this time, the conductive element 122 is maintained in a state with a small current, for example, the current through the conductive element 122 is maintained at 1 mA. This will not cause any health effects on the human body. In addition, when it is not necessary to drive away mosquitoes, the energy consumption generated by the diaphragm 120 can be effectively reduced, saving electricity.

[0046] When a mosquito lands on the diaphragm 120, the surface pressure of the conductive element 122 increases. The pressure sensor 123 detects that the surface pressure of the conductive element 122 is greater than 0. At this time, the pressure sensor 123 transmits the detection signal to the current controller 124. After processing the signal, the current controller 124 controls the current through the conductive element 122 to be greater than the preset current, that is, changes from a small current state to a large current state, such as a current of 5 mA to generate an electric shock to the mosquito, so as to achieve the purpose of repelling the mosquito. In this way, the mosquito attached to the display panel 110 can be repelled by electric shock without human intervention, which is simple and convenient and further ensures the user's viewing experience.

[0047] Furthermore, to prevent users from accidentally touching the display panel 110 and to improve the safety of using the diaphragm 120, this application also makes improvements to the sensor 123 and the current controller 124, as follows:

[0048] When sensor 123 detects that conductive element 122 is in the second state, after a first preset time, sensor 123 transmits the detection signal to current controller 124. Current controller 124 controls the current through conductive element 122 to be greater than a preset current. After a second preset time, current controller 124 controls the current through conductive element 122 to be reduced to a preset current. The first preset time is greater than 30 seconds, and the second preset time is greater than 5 seconds and less than 10 seconds.

[0049] Since users generally do not touch the display panel 110 for a long time and the time of accidental touch is relatively short, while mosquitoes stay on the display panel 110 for a relatively long time, based on this phenomenon, this application has adjusted the detection time of the sensor 123 and the control time of the current controller 124 to distinguish whether it is mosquitoes staying or user accidental touch, so as to ensure user safety.

[0050] The specific working process is as follows: When the sensor 123 detects that the conductive element 122 is in the second state, such as when the resistance of the conductive element 122 increases or the surface pressure of the conductive element 122 is greater than 0, and the duration reaches or exceeds 30 seconds, the sensor 123 will transmit a signal to the current controller 124. The current controller 124 will instantly increase the current passing through the conductive element 122. The large current will pass through the mosquito's body and cause an electric shock to the mosquito, thereby repelling it. After the large current is maintained for 5 seconds, ensuring that all mosquitoes on the display panel 110 can be effectively repelled, the current sensor 123 will send a current reduction signal. The current controller 124 will control the current to be an ultra-small current, reducing the current passing through the conductive element 122 to a preset current level, such as reducing the current of the conductive element 122 to 1 mA. This completes one working cycle. This can effectively prevent the user from accidentally touching the display panel 110 and causing the sensor 123 to misjudge, improve the accuracy of mosquito identification, and further improve the safety of using the diaphragm 120.

[0051] Since some mosquitoes or dust may remain on the display panel 110 after the diaphragm 120 uses electric shock to repel them, in order to keep the display panel 110 clean and ensure its display quality, this application also makes improvements to the display module 100, as follows:

[0052] Figure 4 This is a schematic diagram of the sweeping and blowing device in the fourth embodiment of the display module of this application. Figure 5 This is a schematic diagram of the assembly of the sweeping device and the display panel in the fourth embodiment of the display module of this application, as shown below. Figure 4 and Figure 5As shown, the display module 100 also includes a sweeping and blowing device 130. The sweeping and blowing device 130 includes a housing 131, a guide rod 132, a lead screw 133, a motor 134, a connector 135, a fan 138, and a transmission box 139. The housing 131 is installed on one side of the display panel 110. The guide rod 132 and the lead screw 133 are connected to the side of the housing 131 near the display panel 110, and the guide rod 132 and the lead screw 133 extend in the same direction as the side of the display panel 110. The motor 134 and the transmission box 139 are both located on the side of the housing 131 away from the display panel 110. The motor 134 is connected to the transmission box 139, and the lead screw 138 is connected to the transmission box 139. The transmission box 139 is connected to the motor 134, which drives the transmission box 139 to drive the lead screw 133 to rotate axially. The connecting part 135 includes a first connecting part 136 and a second connecting part 137. The first connecting part 136 is connected to the second connecting part 137. The first connecting part 136 is sleeved on the guide rod 132, and the second connecting part 137 is sleeved on the lead screw 133. The side of the second connecting part 137 away from the first connecting part 136 is connected to the fan 138. The fan 138 is used to sweep and blow the display panel 110. The first connecting part 136 and the second connecting part 137 move simultaneously along the extension direction of the lead screw 133 as the lead screw 133 rotates.

[0053] Unlike the previous embodiment, in this embodiment, a sweeping and blowing device 130 is also installed on the side of the display panel 110. The sweeping and blowing device 130 is used to sweep and blow the display panel 110 to keep the surface of the display panel 110 clean.

[0054] The sweeping and blowing device 130 can be connected to an external power source independently, without utilizing the power supply of the display panel 110 itself, so as to avoid affecting the normal power supply of the display panel 110 after the sweeping and blowing device 130 is started, thus reducing the display effect of the display panel 110.

[0055] When the sweeping device 130 is started, the motor 134 rotates forward, driving the gears in the transmission box 139 to rotate. The gears in the transmission box 139 drive the lead screw 133 to rotate. During the axial rotation of the lead screw 133, the thread on the lead screw 133 drives the second connecting part 137, causing the second connecting part 137 to move along the extension direction of the lead screw 133. Since the first connecting part 136 and the second connecting part 137 are connected together, the first connecting part 136 will also move together with the second connecting part 137 during the movement of the second connecting part 137. The first connecting part 136 moves on the guide rod 132, ensuring that the first connecting part 136 and the second connecting part 137 remain connected during their movement. Maintaining a horizontal position and ensuring the stability of the movement of the first connecting part 136 and the second connecting part 137, the fan 138 moves along the extension direction of the lead screw 133. Since the extension direction of the lead screw 133 is horizontal to the side of the display panel 110, when one end of the fan 138 moves to the other end of the lead screw 133, the sweeping and blowing of the display panel 110 is completed. After the sweeping and blowing of the display panel 110 is completed, the electric shock reverses and drives the fan 138 back to the initial position, thus completing one working cycle. The sweeping and blowing device 130 can effectively clean the residual insects or dust on the display panel 110, ensuring the cleanliness of the display panel 110 and ensuring the display quality of the screen.

[0056] When sensor 123 detects that conductive component 122 is in the first state, the sweeping device 130 performs a sweeping once within a preset time interval; when sensor 123 detects that conductive component 122 is in the second state, and after a third preset time, the sweeping device 130 performs a sweeping once, and the third preset time is greater than the second preset time.

[0057] When no mosquitoes are attached to the display panel 110, the sweeping and blowing device 130 will blow and clean the display panel 110 once at a preset interval to avoid the phenomenon of excessive dust adhering to the display panel 110 after long-term use. The preset interval can be set according to the user's usage. For example, if the preset interval is half an hour, the sweeping and blowing device 130 will sweep and blow the display panel 110 every half hour to ensure the cleanliness of the display panel 110.

[0058] When the mosquito stays on the display panel 110 for more than the second preset time, that is, after the first preset time, the sensor 123 starts to transmit a detection signal to the current controller 124. The current controller 124 amplifies the current to shock and drive away the mosquito. Then, after the second preset time, for example, after 5 seconds, the mosquito on the display panel 110 has been shocked and driven away, and the current of the conductive element 122 has returned to a weak current. After the third preset time, for example, after 6 seconds, the sweeping and blowing device 130 is activated to blow and clean the display panel 110, blowing away the mosquito carcasses.

[0059] Figure 6 This is a schematic diagram of an embodiment of the display device of this application, as shown below. Figure 6 As shown, this application also discloses a display device 10, including a rear shell 200. The display device 10 also includes the aforementioned display module 100, which is installed inside the rear shell 200. The rear shell 200 protects the display module 100 from direct collisions with the outside world, preventing damage to the display module 100. It also prevents external moisture from entering the display module 100 and corroding the electronic components or optical films 120 inside the display module 100, effectively improving the service life of the display device 10.

[0060] The display device 10 in this application is mainly aimed at large-size display devices, such as televisions with a size of 75 inches or more. However, since mosquitoes are attracted to the light source and fly to and stay on the display panel 110, the user's viewing experience is reduced.

[0061] Based on the above problems, this application improves the display module 100 in the display device 10. Specifically, this application provides a film 120 on the light-emitting surface of the display panel 110, and the film 120 has a built-in conductive element 122. The film 120 supplies power to the conductive element 122 by connecting to an external power source. When there are no insects attached to the surface of the display panel 110, the conductive element 122 is in a first state, and the current passing through the conductive element 122 is a preset current. At this time, the conductive element 122 is maintained in a state with a small current, which will not have any impact on the human body. When an insect flies and lands on the film 120, it will change the conductive element 122 from the first state to the second state. At this time, the current passing through the conductive element 122 is greater than the preset current, that is, it changes from a small current state to a large current state, which will generate an electric shock to the insect, thereby achieving the purpose of repelling the insect. In this way, the insects attached to the display panel 110 can be repelled by electric shock without human intervention. This is simple and convenient, further ensuring the user's viewing experience and improving the user experience of the display device 10.

Therefore, without conflict, the embodiments described above or the technical features can be arbitrarily combined to form new embodiments. After the embodiments or technical features are combined, the original technical effect will be enhanced.

[0063] The above description, in conjunction with specific optional embodiments, provides a further detailed explanation of this application and should not be construed as limiting the specific implementation of this application to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of this application, and all such modifications or substitutions should be considered within the scope of protection of this application.
