Abstract
Description
Technical Field
[0001] This application relates to the field of display technology, and in particular to a protection module and a display device having the protection module. Background Technology
[0002] With the development of display technology, display devices have been widely used in many fields and industries. Display devices are no longer limited to indoor use; more and more display devices are also being used outdoors.
[0003] Outdoor humidity is often high (e.g., the air outside is more humid), resulting in higher humidity inside display devices used outdoors. However, since display devices contain numerous circuits, high humidity can damage these circuits, easily causing short circuits and potentially leading to safety hazards.
[0004] Therefore, how to solve the problem of circuit damage or short circuit caused by high humidity inside the display device in the prior art is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a protection module and a display device having the protection module, which aims to solve the problem of circuit damage or short circuit caused by high humidity inside the display device in the prior art.
[0006] To address the aforementioned technical problems, this application provides a protection module disposed within a display device. The display device includes a display panel and a power management circuit electrically connected to the display panel. The protection module includes a humidity detection component, a housing, and multiple magnetic elements. The humidity detection component is connected to the housing, and the multiple magnetic elements are disposed within the housing. An opening penetrating the housing is provided on the side of the housing opposite to the humidity detection component. The protection module includes a moving element and a stationary element. The moving element is electrically connected to the power management circuit and is connected to the stationary element under magnetic force to achieve electrical connection, enabling the power management circuit to provide operating voltage to the display panel. The humidity detection component expands after absorbing moisture to press against the plurality of magnetic elements inside the housing, so that at least one of the plurality of magnetic elements leaves the housing through the opening. The at least one magnetic element leaving the housing generates a magnetic force with the moving element and moves closer to each other. The moving element disconnects from the stationary element, so that the power management circuit stops supplying operating voltage to the display panel.
[0007] In summary, the protection module provided in this application embodiment can prevent the power management circuit from supplying operating voltage to the display panel when the humidity inside the display device is high, thus avoiding circuit damage or short circuit caused by high humidity inside the display device and preventing safety accidents.
[0008] In an exemplary embodiment, the humidity detection component includes a moisture-absorbing box, a plurality of moisture-absorbing elements, and a flexible element. The flexible element is disposed on the side of the moisture-absorbing box facing the receiving box and forms a receiving space with the moisture-absorbing box. The plurality of moisture-absorbing elements are disposed within the receiving space. The moisture-absorbing box has at least one vent hole penetrating through the moisture-absorbing box. The plurality of moisture-absorbing elements are used to absorb moisture through the vent hole and expand to push the flexible element to bulge toward the plurality of magnetic elements. The flexible element is used to hold the plurality of magnetic elements, so that at least one of the plurality of magnetic elements detaches from the receiving box through the opening.
[0009] In an exemplary embodiment, the protective module further includes a first support member, the accommodating housing is disposed on the first support member, the opening of the accommodating housing faces the first support member, and the magnetic element exiting the accommodating housing is supported on the first support member. The protective module further includes a second support member disposed adjacent to the first support member, the movable element is disposed on the second support member and movable relative to the second support member, the stationary element is fixed to the second support member, and the movable element is located on the side of the stationary element facing the magnetic element.
[0010] In an exemplary embodiment, the protective module further includes a first limiting member and a second limiting member. The first limiting member protrudes at least from the edge of the first support member near the second support member and extends toward the receiving housing. The second limiting member protrudes at least from the edge of the second support member near the first support member and extends beyond the surface of the second support member on which the stationary element is supported. The first limiting member and the second limiting member serve to space the moving element from the magnetic element on the first support member.
[0011] In an exemplary embodiment, the protection module further includes a pressure sensing element and an exhaust assembly. The pressure sensing element is embedded within the first carrier, with a portion of the pressure sensing element protruding from the surface of the first carrier that supports the magnetic element. The pressure sensing element is electrically connected to a power supply terminal and the exhaust assembly, respectively. The pressure sensing element is used to sense the pressure applied by the magnetic element and then conduct to electrically connect the exhaust assembly to the power supply terminal. The exhaust assembly is used to expel air from within the display device.
[0012] In an exemplary embodiment, the exhaust assembly includes an exhaust element and a humidity sensing element, the humidity sensing element being electrically connected to the pressure sensing element and the exhaust element. The humidity sensing element is used to selectively connect the humidity sensing element to the pressure sensing element according to the humidity level within the display device, and the exhaust element is used to exhaust air from within the display device.
[0013] In an exemplary embodiment, the protection module further includes a reset assembly disposed on one side of the first carrier. The reset assembly includes a driving element and an actuating element, the driving element being drively connected to the actuating element. The driving element is used to drive the actuating element to move toward the magnetic element located on the first carrier, and the actuating element is used to push the magnetic element away from the first carrier.
[0014] In an exemplary embodiment, each of the magnetic elements includes a magnetic body and an elastic layer, the elastic layer being disposed around the periphery of the magnetic body, and the size of the magnetic body being smaller than the size of the opening, while the size of the elastic layer being larger than the size of the opening.
[0015] In an exemplary embodiment, the magnetic attraction between the magnetic element and the moving element is greater than the magnetic attraction between the moving element and the stationary element.
[0016] Based on the same inventive concept, this application also provides a display device, which includes a housing and the aforementioned protective module, wherein the protective module is disposed within the housing.
[0017] In summary, the display device provided in this application includes a housing and a protective module. When the humidity inside the display device is high, the protective module can cause the power management circuit to stop supplying operating voltage to the display panel, thereby preventing circuit damage or short circuit caused by high humidity inside the display device and thus avoiding safety accidents.

[0034] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the internal structure of the display device disclosed in the first embodiment of this application. Figure 2 This is a rear view structural diagram of the display device disclosed in the first embodiment of this application. In this embodiment, the display device 1 may include a housing 10 and a display panel 30 disposed within the housing 10, with the light-emitting side of the display panel 30 exposed above the housing 10, and the display panel 30 is used to display images.
[0035] In an exemplary embodiment, the display panel 30 may be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display panel, or a micro light-emitting diode (Micro LED) display panel, and this application does not impose any specific limitations on it.
[0036] Understandably, the display device 1 can be used in electronic devices including but not limited to televisions, tablets, laptops, desktop computers, mobile phones, in-vehicle displays, smartwatches, smart bracelets, smart glasses, road signs, and other electronic devices. According to the embodiments of this application, the specific type of the display device 1 is not particularly limited, and those skilled in the art can design it accordingly based on the specific usage requirements of the display device 1; further details will not be elaborated here.
[0037] In an exemplary embodiment, the display device 1 may further include a power management integrated circuit (PMIC), which is electrically connected to the display panel 30. The power management circuit provides the display panel 30 with the operating voltage required for display, such as DVDD voltage, VGH voltage, VGL voltage, VSS voltage, etc. The display device 1 may also include other necessary components and parts such as a driver board, power board, high-voltage board, and button control board. Those skilled in the art can supplement these components according to the specific type and actual function of the display device 1, and further details are omitted here.
[0038] In the embodiments of this application, please refer to Figure 1 and Figure 2 The display device 1 further includes at least one protection module 40, which is disposed within the housing 10, i.e., the protection module 40 is disposed within the display device 1. The protection module 40 is used to control the power management circuit to provide operating voltage to the display panel 30 or to control the power management circuit to stop providing operating voltage to the display panel 30 according to the humidity within the housing 10.
[0039] Please refer to the following: Figure 3 , Figure 3This is a schematic diagram of the protective module in its first operating mode according to the second embodiment of this application. In this mode, the protective module 40 controls the power management circuit to provide operating voltage to the display panel 30. In this embodiment, the protective module 40 includes a humidity detection component 41, a housing 42, and multiple magnetic elements 43. The housing 42 is a hollow box structure with an opening on one side, facing the humidity detection component 41, which is connected to the housing 42. Multiple magnetic elements 43 are disposed within the housing 42. The housing 42 has a through-hole 421 on the side opposite to the humidity detection component 41, with the through-hole 421 opposite to the opening, and the centerline of the through-hole 421 parallel to the centerline of the opening. The protective module 40 also includes a moving element 44 and a stationary element 45. The moving element 44 and the stationary element 45 are connected by magnetic force to achieve electrical connection, and the power management circuit provides operating voltage to the display panel 30.
[0040] Please refer to the following: Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the protection module disclosed in the second embodiment of this application, showing its transformation from a first working mode to a second working mode. Figure 5 This is a schematic diagram of the protective module in its second operating mode according to the second embodiment of this application. In this mode, the protective module 40 controls the power management circuit to stop supplying operating voltage to the display panel 30. The humidity detection component 41 expands after absorbing moisture to press against the plurality of magnetic elements 43 within the housing 42. Under the pressing action of the humidity detection component 41, at least one of the magnetic elements 43 leaves the housing 42 through the opening 421. The magnetic element 43 leaving the housing 42 generates a magnetic force with the moving element 44 and moves closer to it. The moving element 44 disconnects from the stationary element 45 and is separated by a preset distance. The power management circuit then stops supplying operating voltage to the display panel 30.
[0041] It is understood that the protection module 40 includes a first conductive terminal 40a and a second conductive terminal 40b. The first conductive terminal 40a is electrically connected to the stationary element 45 via a wire, and is also electrically connected to the power supply terminal. The second conductive terminal 40b is electrically connected to the moving element 44 via a wire, and is also electrically connected to the power management circuit. When the moving element 44 and the stationary element 45 are in contact and electrically connected, the power supply terminal is connected to the power management circuit through the first conductive terminal 40a, the stationary element 45, the moving element 44, and the second conductive terminal 40b. The power management circuit receives the control signal output from the power supply terminal, thereby providing the display panel 30 with the voltage required for display. When the moving element 44 and the stationary element 45 are separated and disconnected, the power supply terminal is disconnected from the power management circuit, and the power management circuit does not receive the control signal output from the power supply terminal, causing the power supply circuit to stop providing the display panel 30 with the voltage required for display. The protection module 40 provided in this application can also be applied to other electronic devices, and this application does not impose any specific limitations on it.
[0042] In one embodiment of this application, the control electrical signal may be a high-level electrical signal.
[0043] It is also understandable that when the humidity inside the display device 1 is high, the humidity detection component 41 absorbs moisture (hygroscopic) from the display device 1 and expands. This expansion, through the opening, presses against and squeezes the plurality of magnetic elements 43 inside the housing 42, causing at least one of the magnetic elements 43 to leave the housing 42 through the opening 421. The magnetic element 43 leaving the housing 42 generates a magnetic force with the moving element 44, causing the moving element 44 to separate from the stationary element 45. Simultaneously, the moving element 44 and the magnetic element 43 leaving the housing 42 move closer to each other. The separation between the moving element 44 and the stationary element 45 causes the power management circuit to stop supplying operating voltage to the display panel 30, preventing circuit damage or short circuits caused by high humidity inside the display device 1, thereby avoiding safety accidents. Furthermore, the humidity detection component 41 absorbs some moisture from the display device 1, reducing the humidity inside the display device 1. In this application, the area within the display device 1 refers to the region between the display panel 30 and the housing 10.
[0044] In an exemplary implementation, please refer to Figure 3The housing 42 can be a frustum-shaped shell or a pyramidal shell. The larger end face of the housing 42 has the opening, and the smaller end face has the aperture 421. The aperture 421 and the opening are opposite each other, and the centerline of the aperture 421 is parallel to the centerline of the opening. A magnetic shielding layer can be provided inside the housing 42 to separate the multiple magnetic elements 43, preventing them from attracting each other.
[0045] Please see Figure 6 , Figure 6 This is a schematic diagram of the internal structure of the magnetic element of the protection module disclosed in the second embodiment of this application. In this embodiment, the magnetic element 43 can be spherical in shape. Each magnetic element 43 includes a magnetic body 431 and an elastic layer 432. The elastic layer 432 is disposed on the periphery of the magnetic body 431, and the size of the magnetic body 431 is smaller than the size of the opening 421, while the size of the elastic layer 432 is larger than the size of the opening 421.
[0046] It is understood that when the humidity detection component 41 is not abutting against the plurality of magnetic elements 43 within the housing 42, the magnetic element 43 will not leave the housing 42 through the opening 421 because the size of the elastic layer 432 of the magnetic element 43 is larger than the size of the opening 421. When the humidity detection component 41 abuts against the plurality of magnetic elements 43 within the housing 42, the magnetic element 43 abuts against the inner wall of the opening 421. The inner wall of the opening 421 causes the elastic layer 432 to deform. And because the size of the magnetic body 431 is smaller than the size of the opening 421, the magnetic element 43 can leave the housing 42 through the opening 421 after elastic deformation.
[0047] In this embodiment of the application, the magnetic attraction between the magnetic element 43 and the moving element 44 is greater than the magnetic attraction between the moving element 44 and the stationary element 45. As a result, after the magnetic element 43 and the moving element 44 generate a magnetic force, the moving element 44 separates from the stationary element 45, while the moving element 44 moves toward the magnetic element 43.
[0048] In an exemplary embodiment, the magnetic body 431 may be a permanent magnet, and one of the moving element 44 and the stationary element 45 may be a permanent magnet, while the other may be a permanent magnet or a magnetic object. The magnetic object itself is not magnetic, but can be magnetized by the magnetic field of the permanent magnet, thereby generating magnetism. The material of the permanent magnet may include any one or more of neodymium iron boron, samarium cobalt, alnico, iron nickel cobalt, barium ferrite, and strontium ferrite, etc. The material of the magnetic object may include any one or more of iron, cobalt, nickel, gold, copper, and iron alloys, etc., and this application does not impose specific limitations on these materials. The material of the elastic layer 432 may include rubber.
[0049] In the embodiments of this application, please refer to Figure 3 The humidity detection component 41 includes a moisture-absorbing box 411, multiple moisture-absorbing elements 412, and a flexible element 413. The moisture-absorbing box 411 has a frame structure and at least one vent 411a penetrating through it. The flexible element 413 is disposed on the side of the moisture-absorbing box 411 facing the receiving box 42, and together with the moisture-absorbing box 411, forms a receiving space 41a. The multiple moisture-absorbing elements 412 are disposed within the receiving space 41a and are separated from the multiple magnetic elements 43 within the receiving box 42 by the flexible element 413. Please refer to [link / reference]. Figure 4 and Figure 5 The plurality of moisture-absorbing elements 412 are used to absorb moisture through the vent holes 411a and expand within the accommodating space 41a to push the flexible element 413 to bulge toward the plurality of magnetic elements 43. The flexible element 413 is used to hold the plurality of magnetic elements 43, so that at least one of the plurality of magnetic elements 43 leaves the accommodating box 42 through the opening 421.
[0050] In an exemplary embodiment, the moisture-absorbing box 411 may be a cylindrical shell with an open end facing the accommodating box 42. The flexible element 413 is detachably disposed at the open end of the moisture-absorbing box 411 to form the accommodating space 41a. The moisture-absorbing box 411 is connected to the accommodating box 42, specifically, the open end of the moisture-absorbing box 411 is connected to the open end of the accommodating box 42, and the open end of the moisture-absorbing box 411 is directly opposite the opening of the accommodating box 42. The flexible element 413 separates the plurality of moisture-absorbing elements 412 in the moisture-absorbing box 411 from the plurality of magnetic elements 43 in the accommodating box 42.
[0051] In the embodiments of this application, please refer to Figure 4 and Figure 5The protective module 40 further includes a first support member 47 and a second support member 48 arranged adjacent to each other. The first support member 47 and the second support member 48 can be arranged on the same horizontal plane and spaced apart. The accommodating box 42 is disposed on the first support member 47, and the opening 421 of the accommodating box 42 faces the first support member 47. The humidity detection component 41 is disposed on the side of the accommodating box 42 opposite to the first support member 47. The magnetic element 43, which leaves the accommodating box 42, falls onto the first support member 47 under the action of gravity. The moving element 44 and the stationary element 45 are disposed on the second support member 48, and the stationary element 45 is fixed to the second support member 48. The moving element 44 is located on the side of the stationary element 45 facing the magnetic element 43, and the moving element 44 can move relative to the second support member 48.
[0052] It should be noted that the magnetic element 43 and the moving element 44, which are separated from the housing 42, generate a magnetic force and move closer to each other. The magnetic element 43 slides on the first support member 47, and the moving element 44 slides on the second support member 48.
[0053] In this embodiment, the surface of the magnetic element 43 can be a smooth arc surface to reduce the contact area between the magnetic element 43 and the first support member 47, which facilitates the sliding of the magnetic element 43 on the first support member 47. Similarly, the surface of the moving element 44 can be a smooth arc surface to reduce the contact area between the moving element 44 and the second support member 48, which also facilitates the sliding of the moving element 44 on the second support member 48.
[0054] In an exemplary embodiment, both the magnetic element 43 and the moving element 44 can be spherical or ellipsoidal, and the stationary element 45 can be cylindrical.
[0055] In the embodiments of this application, please refer to Figure 4 and Figure 5The protective module 40 further includes a first limiting member 51 and a second limiting member 52. The first limiting member 51 is at least disposed on the side of the first support member 47 facing the second support member 48, and the height of the first limiting member 51 is higher than the height of the first support member 47. That is, the first limiting member 51 protrudes at least from the edge of the first support member 47 near the second support member 48 and extends upward from the first support member 47. The second limiting member 52 is at least disposed on the side of the second support member 48 facing the first support member 47, and the height of the second limiting member 52 is higher than the height of the second support member 48. That is, the second limiting member 52 protrudes at least from the edge of the second support member 48 near the first support member 47 and extends upward from the second support member 48, meaning the second limiting member extends beyond the surface of the second support member 48 on which the stationary element 44 is supported. The height is referenced to the surface of the first support member 47 facing the accommodating housing 42.
[0056] Please see Figure 5 The first limiting member 51, located near the second support member 48, abuts against the magnetic element 43 on the first support member 47, while the second limiting member 52, located near the first support member 47, abuts against the moving element 44. The first limiting member 51 and the second limiting member 52 serve to separate the moving element 44 from the magnetic element 43 on the first support member 47, facilitating the movement of the magnetic element 43 away from the moving element 44 and preventing direct contact between them. Due to magnetic force, it is not easy to separate the magnetic element 43 from the moving element 44. It is understood that once the magnetic element 43 is moved away from the moving element 44, the magnetic force between them can be weakened or eliminated, allowing the moving element 44 to move back to the stationary element 45. The first limiting member 51 also serves to confine the magnetic element 43 to the first support member 47, preventing it from moving outside the first support member 47. The second limiting member 52 is also used to restrict the moving element 44 on the second support member 48 to prevent the moving element 44 from moving to an area outside the second support member 48.
[0057] It should be noted that the first limiting member 51 can also be disposed on multiple sides of the first supporting member 47, and the second limiting member 52 can also be disposed on multiple sides of the second supporting member 48. The height of the first limiting member 51 only needs to be sufficient to prevent the magnetic element 43 from leaving the area where the first supporting member 47 is located, and the height of the second limiting member 52 only needs to be sufficient to prevent the moving element 44 from leaving the area where the second supporting member 48 is located. This application does not impose specific limitations on this.
[0058] In the embodiments of this application, please refer to Figure 4 and Figure 5 The protection module 40 further includes a pressure sensing element 53 and an exhaust assembly 55. The pressure sensing element 53 can be embedded in the first support member 47, and a portion of the pressure sensing element 53 protrudes from the surface of the first support member 47 that supports the magnetic element 43. The exhaust assembly 55 communicates with both the interior and exterior of the display device 1. The pressure sensing element 53 is electrically connected to both a power supply terminal and the exhaust assembly 55, selectively connecting the power supply terminal to the exhaust assembly 55. Specifically, when the pressure sensing element 53 contacts the magnetic element 43, the pressure sensing element 53 conducts, and the exhaust assembly 55 is electrically connected to the power supply terminal and begins to operate. The exhaust assembly 55 is used to expel air from the display device 1 to reduce the humidity inside the display device 1.
[0059] It should be noted that the magnetic element 43 will move above the pressure sensing element 53, thereby pressing down on the pressure sensing element 53. After the pressure sensing element 53 senses the pressure applied by the magnetic element 43, the pressure sensing element 53 will be turned on.
[0060] In an exemplary embodiment, the pressure sensing element 53 may be a piezoresistor. When the magnetic element 43 is not pressed on the pressure sensing element 53, the resistance of the pressure sensing element 53 is relatively high, and the exhaust assembly 55 is disconnected from the power supply terminal. When the magnetic element 43 is pressed on the pressure sensing element 53, the resistance of the pressure sensing element 53 is relatively low, and the exhaust assembly 55 is electrically connected to the power supply terminal, thereby enabling the exhaust assembly 55 to operate and expel air from the display device 1.
[0061] In the embodiments of this application, please refer to Figure 4 and Figure 5The exhaust assembly 55 includes an exhaust element 541 and a humidity sensing element 542. The humidity sensing element 542 is electrically connected between the pressure sensing element 53 and the exhaust element 541, and is selectively connected to the pressure sensing element 53 according to the humidity level inside the display device 1. Specifically, when the humidity sensing element 542 senses that the humidity inside the display device 1 is greater than or equal to a preset humidity value, the humidity sensing element 542 is turned on to electrically connect the pressure sensing element 53 and the exhaust element 541; when the humidity sensing element 542 senses that the humidity inside the display device 1 is less than the preset humidity value, the humidity sensing element 542 is turned off to disconnect the pressure sensing element 53 from the exhaust element 541. The exhaust element 541 is used to exhaust air from inside the display device 1.
[0062] Understandably, when the humidity inside the display device 1 exceeds the preset humidity value, the humidity sensing element 541 is activated, the magnetic element 43 disengages from the housing 42 to the first support member 47, and the magnetic element 43 presses against the pressure sensing element 53, thus activating the pressure sensing element 53 and causing the exhaust assembly 55 to operate. After the exhaust assembly 55 has been operating for a period of time, when the humidity inside the display device 1 falls below the preset humidity value, the humidity sensing element 542 is deactivated, causing the exhaust assembly 55 to stop operating. The above technical solution achieves the automatic start and stop of the exhaust assembly 55.
[0063] In an exemplary embodiment, the humidity sensing element 542 may be a lithium chloride device, and the resistance of the humidity sensing element 542 decreases as the humidity increases. The exhaust element 541 may be a fan, and the housing 10 has an exhaust port that penetrates the housing 10, with the exhaust element 541 embedded in the exhaust port.
[0064] Please see Figure 7 , Figure 7 This is a top view of the reset assembly of the protection module disclosed in the second embodiment of this application. In this embodiment, the protection module 40 further includes a reset assembly 56 disposed on one side of the first support member 47. The reset assembly 56 includes a driving element 561 and an actuating element 562. The driving element 561 and the actuating element 562 are drively connected. The driving element 561 drives the actuating element 562 to move towards the magnetic element 43 located on the first support member 47. The actuating element 562 pushes the magnetic element 43, causing the magnetic element 43 to leave the first support member 47. Please refer to [link to relevant documentation]. Figure 8 , Figure 8This is a schematic diagram of the protection module disclosed in the second embodiment of this application switching from a second working mode to a first working mode. The moving element 44 moves to the stationary element 45 under the action of magnetic force. The moving element 44 and the stationary element 45 are connected electrically, so that the power management circuit provides operating voltage to the display panel 30.
[0065] It should be noted that the driving element 561 can operate under user control or automatically according to the humidity within the display device 1; this application does not impose specific limitations on this. The driving element 561 is also used to drive the actuator 562 away from the area where the first support member 47 is located, that is, the driving element 561 drives the actuator 562 to reset. The area where the actuator 562 moves and the area where the actuator 562 pushes the magnetic element 43 away from the first support member 47 are not provided with the first limiting member 51.
[0066] In an exemplary embodiment, the driving element 561 may be a motor, and the transmission connection may be a belt transmission connection, a gear transmission connection, a worm gear transmission connection, a shaft transmission connection, a chain transmission connection, or a helical transmission connection, etc.
[0067] In summary, the protection module 40 provided in the second embodiment of this application includes a humidity detection component 41, a housing 42, and a plurality of magnetic elements 43. The humidity detection component 41 is connected to the housing 42, and the plurality of magnetic elements 43 are disposed within the housing 42. The housing 42 has an opening 421 that penetrates through the housing 42. The protection module 40 also includes a moving element 44 and a stationary element 45. The moving element 44 and the stationary element 45 are connected under magnetic force to achieve electrical connection, so that the power management circuit provides operating voltage to the display panel 30. The humidity detection component 41 expands after absorbing moisture to support the plurality of magnetic elements 43 within the housing 42, and the magnetic elements 43 exit the housing 42 through the opening 421. The magnetic element 43, separated from the housing 42, generates a magnetic force with the moving element 44. The magnetic element 43 and the moving element 44 are disconnected from the stationary element 45 and spaced a preset distance apart. This causes the power management circuit to stop supplying operating voltage to the display panel 30, preventing circuit damage or short circuits caused by high humidity within the display device 1, thus avoiding safety accidents. Furthermore, the humidity detection component 41 absorbs some moisture from within the display device 1 to reduce humidity.
