However, with the increase in on-board display modules, when a vehicle collision occurs, the display panel in the display module is shattered, and the debris splashes and injures people, which becomes a major safety hazard. To address this problem, a layer of PET (polyethylene terephthalate) film is currently attached to the surface of the display panel of the display module to prevent the debris generated by the display panel from splashing and causing harm to the human body when the display panel is shattered during a vehicle collision. However, the PET film will affect the display brightness of the display module, thereby reducing the display effect of the display module and the touch feel of the display module.

[0053] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be more comprehensive and complete and will fully convey the concept of the example embodiments to those skilled in the art.

[0054] In addition, the described features, structures or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other cases, known methods, devices, implementations or operations are not shown or described in detail to avoid blurring the various aspects of the present disclosure.

[0055] The present disclosure is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be understood as limiting the present disclosure.

[0056] like Figure 1 and Figure 2 As shown, the present disclosure provides a display module 2, including a display panel 21 and an explosion-proof component 22. The display panel 21 has a display surface, and the display surface includes a display area and a non-display area. The display area is used to display the screen of the display module 2, and the non-display area is arranged around the display area.

[0057] The explosion-proof component 22 is arranged close to the display panel 21 , and includes an explosion-proof membrane 221 and a push-out structure 222 . The explosion-proof membrane 221 is connected to the push-out structure 222 and moves with the push-out structure 222 . The push-out structure 222 has an initial position and an explosion-proof position.

[0058] In the initial position, the ejection structure 222 is located in the non-display area of ​​the display panel 21, the explosion-proof membrane 221 is at least partially located in the non-display area, and the explosion-proof membrane 221 located in the non-display area is connected to the ejection structure 222. In the explosion-proof position, the ejection structure 222 is away from the initial position and enters the non-display area from the display area. Driven by the ejection structure 222, the explosion-proof membrane 221 enters the display area and shields part of the display surface.

[0059] The length of the explosion-proof membrane 221 in the present disclosure can be greater than or equal to the length of the display surface, and at the same time, the width of the explosion-proof membrane 221 can be greater than or equal to the width of the display surface, so that when the push-out structure 222 is in the explosion-proof position, the explosion-proof membrane 221 can completely cover the display surface under the drive of the push-out structure 222, but is not limited to this. The length of the explosion-proof membrane 221 can also be less than the length of the display surface, and the width of the explosion-proof membrane 221 can also be less than the width of the display surface.

[0060] If the length of the explosion-proof membrane 221 is smaller than the length of the display surface, or the width of the explosion-proof membrane 221 is smaller than the width of the display surface, when in the explosion-proof position, the explosion-proof membrane 221 and other structures covering the display surface of the display panel 21 can also cover the display surface together to reduce the splashing of debris and the harm to the human body when the display panel 21 is broken, which is also included in the scope of the present disclosure.

[0061] It should be noted that the explosion-proof film 221 can shield the display surface partially or completely. For example, the explosion-proof film 221 can only shield the display area of ​​the explosion-proof film 221, but not the non-display area of ​​the explosion-proof film 221. However, it is not limited to this. The explosion-proof film 221 can also completely shield the display surface, thereby further reducing the possibility of debris flying and causing harm to the human body after the display panel 21 is broken.

[0062] The present disclosure sets an explosion-proof component 22 in the display module 2, and utilizes the characteristic that the push-out structure 222 can be adjusted from the initial position to the explosion-proof position. Therefore, the push-out structure 222 can be adjusted to the explosion-proof position to drive the explosion-proof film 221 to shield the display surface of the display panel 21. When the display panel 21 is broken, the explosion-proof film 221 can shield the debris of the display panel 21, thereby reducing the possibility of the debris of the display panel 21 splashing and causing harm to the human body. In addition, before the display panel 21 is broken, the explosion-proof component 22 is located in the area outside the display area of ​​the display module 2, so that before the display panel 21 is broken, the explosion-proof component 22 can be avoided from affecting the normal display brightness and touch feel of the display module 2, thereby improving the user experience.

[0063] It should be noted that in the embodiment of the present disclosure, the length of the display area is greater than that of the non-display area. In order to ensure that the explosion-proof film 221 can at least completely cover the display area, the length of the explosion-proof film 221 should be at least greater than the length of the display area. Therefore, the length of the explosion-proof film 221 will also be greater than the length of the non-display area. In order to avoid the explosion-proof film 221 from shielding the display area and affecting the display image of the display panel 21 in the initial position, the present disclosure can bend the explosion-proof film 221 at the edge of the display panel 21 toward the side away from the display surface of the display panel 21, so that part of the explosion-proof film 221 is placed on the display surface, and part of the explosion-proof film 221 is located on the side of the display panel 21 away from the display surface, thereby preventing the explosion-proof film 221 from entering the display area and blocking the display image of the display panel 21, so as to ensure the display effect of the display module 2. At the same time, the display module 2 can accommodate the explosion-proof film 221 whose length is greater than the non-display area to ensure that the explosion-proof film 221 can at least completely shield the display area. However, the present invention is not limited to this. The explosion-proof membrane 221 can also be folded, so that the explosion-proof membrane 221 with a length greater than the non-display area can be placed in the non-display area. For example, the folding method of the explosion-proof membrane 221 can be similar to the folding method of a folding fan, so that the explosion-proof membrane 221 with a length greater than the non-display area can be placed in the non-display area.

[0064] In the embodiment of the present disclosure, the explosion-proof film 221 can be made of a non-stretchable optical film, such as an optical film made of polycarbonate (PC) material, so that when the explosion-proof film 221 shields the display surface driven by the push-out structure 222, the possibility of being easily cut by debris of the display panel 21 due to the thinning of the thickness of the optical film after extension can be reduced, so as to improve the safety of the display module 2. However, it is not limited to this. The explosion-proof film 221 can also be made of a stretchable optical film. If the explosion-proof film 221 can still prevent the debris of the display panel 21 from splashing and causing harm to the human body when the explosion-proof film 221 shields the display area, it also belongs to the scope of the present disclosure. In addition, other non-optical films that can shield the display panel 21 to limit the possibility of debris of the display panel 21 splashing and causing harm to the human body are also included in the scope of the present disclosure.

[0065] The thickness range of the explosion-proof membrane 221 in the present disclosure is: 0.2mm-0.4mm, and the thickness of the explosion-proof membrane 221 can be: 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, etc., but not limited to this, and can be determined according to actual conditions.

[0066] like Figure 2 and Figure 3As shown, in the embodiment of the present disclosure, the ejection structure 222 may include a propeller 2221, and the explosion-proof membrane 221 may be connected to the propeller 2221. The propeller 2221 is used to provide power for the ejection structure 222 to move from an initial position to an explosion-proof position, so that the explosion-proof membrane 221, driven by the propeller 2221, shields the display area.

[0067] It should be noted that the power provided by the propeller 2221 can ensure that the explosion-proof film 221 can completely shield the display area when in the explosion-proof position.

[0068] When the propeller 2221 is adjusted from the initial position to the explosion-proof position, the moving path of the propeller 2221 may only include the non-display areas on the opposite sides of the display panel 21 in the width direction, but is not limited to this. The moving path of the propeller 2221 may also pass through the display area of ​​the display panel 21, which can be set specifically according to actual conditions.

[0069] In addition, the ejection structure 222 in the present disclosure can be provided with a pusher, but is not limited to this. Two or more pushers can also be provided in the ejection structure 222 to increase the power when the ejection structure 222 moves from the initial position to the explosion-proof position, and reduce the situation where the ejection structure 222 is insufficiently powered when it moves from the initial position to the explosion-proof position, thereby ensuring that in the explosion-proof position, the explosion-proof membrane 221 can completely cover the display area, reducing the possibility that when the display panel 21 is broken, the fragments of the display panel 21 will splash and cause harm to the human body.

[0070] In the embodiment of the present disclosure, the ejection structure 222 may further include a guide plate 2222, the thruster 2221 is connected to the side of the guide plate 2222 away from the display panel 21, the explosion-proof membrane 221 may be connected to the guide plate 2222, and when the guide plate 2222 is adjusted from the initial position to the explosion-proof position driven by the thruster 2221, the explosion-proof membrane 221 may shield the display surface.

[0071] The guide plate 2222 can be made of stainless steel material, so that the guide plate 2222 can have sufficient strength to drive the explosion-proof membrane 221 to move, and can also reduce the possibility of the guide plate 2222 being corroded after contacting water vapor, so as to improve the service life of the display module 2, but not limited to this. Other materials with a certain strength to drive the explosion-proof membrane 221 to shield the display area can be used as the material for making the guide plate 2222 in the present disclosure.

[0072] The connection between the explosion-proof membrane 221 and the guide plate 2222 can be that one end of the explosion-proof membrane 221 is folded and hidden under the light guide plate 4, and bonded and fixed to the light guide plate 4, but is not limited to this. One end of the explosion-proof membrane 221 can also be bonded and fixed to the side of the light guide plate 4 away from the center of the display area. The specific connection can be determined according to actual conditions.

[0073] It should be noted that, in the initial position, the guide plate 2222 in the present disclosure can be completely placed in the non-display area, but is not limited to this. The guide plate 2222 can also be partially placed in the non-display area and partially extend outside the display surface of the display panel 21, but the guide plate 2222 will not form an obstruction to the display area in the initial position, so as to reduce the obstruction of the display panel 21 display screen by the guide plate 2222 and improve the display effect of the display module 2.

[0074] In addition, the width of the guide plate 2222 can be greater than the width of the explosion-proof membrane 221. The connection portion between the explosion-proof membrane 221 and the guide plate 2222 is in a flat state. When the explosion-proof membrane 221 is connected to the guide plate 2222, the explosion-proof membrane 221 can be fully unfolded to reduce the possibility that the explosion-proof membrane 221 located in the display area is folded, which causes the explosion-proof membrane 221 to be unable to completely cover the display area. However, the present invention is not limited to this. Other widths of the guide plate 2222 that can ensure that the explosion-proof membrane 221 can completely cover the display area when in the explosion-proof position are all included in the scope of the present disclosure.

[0075] It should be noted that when two propellers 2221 are provided in the ejection structure 222, the two propellers 2221 can be separately provided at the opposite ends of the guide plate 2222, that is: the two propellers 2221 are respectively located at the opposite ends of the guide plate 2222 in the width direction, but not limited to this, the two propellers 2221 can also be provided at any position on the side of the guide plate 2222 away from the display panel 21, which can be determined according to actual conditions.

[0076] like Figure 4 As shown, in the embodiment of the present disclosure, the display module 2 may further include a starting structure 23, which is disposed close to the propeller 2221, and is used to start the propeller 2221 to move the propeller 2221 from the initial position to the explosion-proof position.

[0077] In the exemplary embodiment of the present disclosure, the starting structure 23 and the explosion-proof membrane 221 are located on the same side of the thruster 2221 and are spaced apart from the thruster 2221 ; when the starting structure 23 senses an explosion, the starting structure 23 responds to the explosion and moves toward the thruster 2221 to start the thruster 2221 .

[0078] Specifically, the thruster 2221 may include: a main body 2221a, a guide cavity 2221b, and a lead 2221c. The main body 2221a is surrounded by a receiving groove, and the groove opening of the receiving groove faces the starting structure 23, and the receiving groove is used to place the propellant; the guide cavity 2221b is located on the side of the main body 2221a close to the starting structure 23, the guide cavity 2221b is connected to the main body 2221a, and the guide cavity 2221b is arranged corresponding to the groove; a part of the lead 2221c is located in the receiving groove and in contact with the propellant, and another part of the lead 2221c is placed in the guide cavity 2221b.

[0079] The starting structure 23 includes a charged arcing needle 231. When the starting structure 23 responds to the explosion vibration, the charged arcing needle 231 generates an arc to ignite the lead 2221c, thereby prompting the propellant to generate power.

[0080] It should be noted that "starting structure 23 responding to explosion vibration" may refer to a situation where, when the display module 2 experiences severe vibrations such as collision or explosion, the starting structure 23 senses severe vibrations and moves toward the thruster 2221, but is not limited to this. "Starting structure 23 responding to explosion vibration" may also refer to a situation where the starting structure 23 detects that the display panel 21 is broken, and the starting structure 23 starts the thruster 2221 to move to the explosion-proof position.

[0081] In the disclosed embodiment, the lead cavity 2221b may be made of metal material, so that when the starting structure 23 moves toward the thruster 2221, the charged arcing needle 231 may be induced by the lead cavity 2221b and generate an arc, thereby igniting the lead 2221c and prompting the propellant to generate power.

[0082] Furthermore, the propellant may be gunpowder. When the fuse 2221c is ignited, the fuse 2221c ignites the gunpowder, thereby generating a large amount of gas to push the guide plate 2222 to move to the explosion-proof position. However, the propellant in the present disclosure is not limited to being made of gunpowder. Other materials that can generate a large amount of gas when the fuse 2221c is ignited and can provide power for adjusting the ejection structure 222 from an initial position to an explosion-proof position can all be used as materials for making the propellant in the present disclosure.

[0083] In the embodiment of the present disclosure, the starting structure 23 may include: a magnetic wall 232, a connecting plate 233, an elastic member 234 and a magnetic member 235, wherein the magnetic wall 232 is located on the side of the charged arc-starting needle 231 away from the propeller 2221; the connecting plate 233 is located between the magnetic wall 232 and the propeller 2221, and the side of the connecting plate 233 close to the propeller 2221 is connected to the charged arc-starting needle 231; one end of the elastic member 234 is connected to the side of the magnetic wall 232 close to the propeller 2221, and the other end is connected to the side of the connecting plate 233 away from the propeller 2221; the magnetic member 235 is connected to the connecting plate 233; the charged arc-starting needle 231 is arranged corresponding to the lead cavity 2221b.

[0084] For example, the magnetic wall 232 in the embodiment of the present disclosure may be made of a metal material to generate an attractive force on the magnetic member 235 , but is not limited thereto. The magnetic wall 232 may also be made of other magnetic materials that can generate an attractive force on the magnetic member 235 .

[0085] The magnetic member 235 may be made of a magnet, but is not limited thereto. Other materials that can be attracted by the magnetic wall 232 may be used as the material for making the magnetic member 235 in the present disclosure.

[0086] The elastic member 234 may be made of a spring, but is not limited thereto. Other materials that can generate elastic force under the action of the connecting plate 233 and the magnetic wall 232 are all within the scope of the present disclosure.

[0087] The connecting plate 233 is used for connecting with the elastic member 234, the charged arc-starting needle 231 and the magnetic member 235. A certain distance is maintained between the connecting plate 233 and the magnetic wall 232 and the thruster 2221. Thus, when no explosion occurs, the position of the connecting plate 233 can maintain the constant attraction of the magnetic wall 232 on the magnetic member 235 and the elastic force of the elastic member 234, and no electric induction occurs between the charged arc-starting needle 231 and the lead cavity 2221b. When an explosion occurs, the magnetic member 235 breaks away from the attraction of the magnetic wall 232, so that the elastic member 234 pushes the connecting plate 233 to move toward the thruster 2221. When the distance between the charged arcing needle 231 and the lead cavity 2221b decreases and electric induction occurs between the charged arcing needle 231 and the lead cavity 2221b, the lead 2221c in the lead cavity 2221b is ignited, thereby prompting the propellant to produce a large amount of gas, providing power for the ejection structure 222 to move to the explosion-proof position, and driving the explosion-proof membrane 221 to shield the display area.

[0088] It should be noted that the connecting plate 233 in the embodiment of the present disclosure can be made of non-magnetic material. When the display module 2 does not experience explosive vibration, the magnetic wall 232 has an attractive force on the magnetic part 235, and under the action of the connecting plate 233 and the magnetic wall 232, the elastic part 234 generates a certain elastic force. The attractive force of the magnetic wall 232 on the magnetic part 235 is the same in magnitude and opposite in direction to the elastic force of the elastic part 234, thereby maintaining a constant distance between the magnetic wall 232 and the connecting plate 233, preventing the starting structure 23 from moving toward the side close to the thruster 2221, causing the charged arcing needle 231 to be electrically inductively coupled to the lead cavity 2221b, and igniting the lead 2221c, causing the propellant to produce a large amount of gas, thereby ensuring that when the display module 2 does not experience explosive vibration, the explosion-proof membrane 221 will not shield the display panel 21, so as to ensure the picture display effect of the display module 2.

[0089] In addition, the connecting plate 233 can also be made of magnetic material. At this time, the sum of the attractive forces of the magnetic wall 232 on the connecting plate 233 and the magnetic member 235 is the same in magnitude and opposite in direction to the elastic force of the elastic member 234, thereby maintaining a constant distance between the magnetic wall 232 and the connecting plate 233, preventing the starting structure 23 from moving toward the side close to the thruster 2221, and ensuring that when the display module 2 does not experience explosive vibration, the explosion-proof membrane 221 will not shield the display panel 21, thereby ensuring the picture display effect of the display module 2.

[0090] In the embodiment of the present disclosure, the way in which the starting structure 23 starts the thruster 2221 is not limited to the way in which the starting structure 23 ignites the propellant to generate gas in the above-mentioned embodiment. The starting structure 23 can also start the thruster 2221 by the starting structure 23 spraying a large amount of gas to the thruster 2221 to provide power for the pop-up device to move from the initial position to the explosion-proof position. At this time, the starting structure 23 may include an inflatable component. After sensing severe vibration, the starting structure 23 controls the inflatable structure to spray a large amount of gas to the thruster 2221, so that the thruster 2221 moves from the initial position to the explosion-proof position under the action of the inflatable component.

[0091] In addition, except for the position on the same side of the propeller 2221 as the explosion-proof membrane 221, other positions that can enable the starting device to start the propeller 2221 to move from the initial position to the explosion-proof position and completely cover the display area without blocking the display area are all included in the scope of the present disclosure.

[0092] In the embodiment of the present disclosure, the ejection structure 222 may include a sliding portion, and the sliding portion is located on a side of the ejection structure 222 close to the explosion-proof membrane 221 .

[0093] The explosion-proof component 22 includes a guide groove, which is located in the non-display area and extends in the length direction of the display panel 21. The guide groove is used to place the sliding part. When the ejection structure 222 is adjusted from the initial position to the explosion-proof position, the sliding part slides along the guide groove.

[0094] It should be noted that after the display module 2 is subjected to a severe impact, the moving direction of the ejection structure 222 may deviate from the preset sliding path, resulting in the explosion-proof membrane 221 being unable to completely shield the display area. By providing a sliding portion and a guide groove, the ejection structure 222 can be moved from the initial position to the explosion-proof position while the sliding portion can stably slide along the extension direction of the guide groove, thereby reducing the possibility that the moving direction of the ejection structure 222 deviates from the preset sliding path due to external impact force. This ensures that in the explosion-proof position, the explosion-proof membrane 221 can completely shield the display area, reducing the possibility that debris from the display panel 21 is splashed after the display panel 21 is broken and causes harm to the human body, thereby improving the safety of the display module 2.

[0095] For example, the sliding portion may be a slider, and the guide groove may be a slide groove matched with the slider. The slide groove is located in the non-display area to reduce the obstruction of the display area and ensure the display effect of the display panel 21.

[0096] In addition, the sliding part can also be a pulley, which rolls along the guide groove to reduce the resistance of the ejection structure 222 when it moves from the initial position to the explosion-proof position, thereby increasing the moving speed of the ejection structure 222 and shortening the time it takes for the explosion-proof film 221 to completely cover the display area, further reducing the possibility of debris splashing after the display panel 21 is broken and causing harm to the human body, thereby improving the safety of the display module 2.

[0097] Two guide grooves can be set in the explosion-proof component 22, and the two guide grooves are located on opposite sides of the display panel 21 in the width direction. The two opposite ends of the sliding part move from the initial position to the explosion-proof position along the guide grooves, which can reduce the uneven sliding speed of the two opposite ends of the sliding part, thereby reducing the movement speed of the ejection structure 222. The situation occurs, thereby speeding up the completion of the explosion-proof film 221 to completely cover the display area, reducing the possibility of debris splashing after the display panel 21 is broken and causing harm to the human body, thereby improving the safety of the display module 2.

[0098] In the embodiment of the present disclosure, the display panel 21 includes a display component and a diffusion film 213, and the diffusion film 213 is located on a side of the display component away from the ejection structure 222. Further, the display component may include a display screen 212 and a touch screen 211, and the display screen 212 is located on a side of the touch screen 211 away from the ejection structure 222. When the ejection structure 222 is adjusted from the initial position to the explosion-proof position, driven by the ejection structure 222, the explosion-proof film 221 covers the side of the touch screen 211 away from the liquid crystal layer, thereby reducing the possibility of the display screen 212, the touch screen 211 and other structures in the display panel 21 being broken, and the possibility of debris splashing and causing harm to the human body.

[0099] It should be noted that when the explosion-proof membrane 221 is bent toward the side of the touch screen 211 close to the display screen 212, part of the explosion-proof membrane 221 can be placed between the display screen 212 and the diffusion membrane 213. When the pushing structure 222 is adjusted from the initial position to the explosion-proof position, the pushing structure 222 drives the explosion-proof membrane 221 to shield the display area, so that the explosion-proof membrane 221 located between the display screen 212 and the diffusion membrane 213 is pulled out and moved to the display surface to shield the display area.

[0100] The present disclosure provides a display device 1, comprising any display module 2 as described above. In addition, the display device 1 may also include: a back plate 3, a light guide plate 4, a plastic frame 5 and a front frame 6, wherein the back plate 3 is located on the side of the display panel 21 away from the display surface, and can be used to provide support for structures such as the display panel 21; the light guide plate 4 is located on the side of the back plate 3 close to the display panel 21, and is used to guide light to improve the display effect of the display device 1; the plastic frame 5 is located between the back plate 3 and the display panel 21, and is used to achieve a fixed connection between the display panel 21 and the back plate 3. At the same time, the plastic frame 5 can also be located between the light guide plate 4 and the display panel 21 to fix the light guide plate 4 and the display panel 21, and can form a support for the display panel 21.

[0101] The front frame 6 may include a first frame body and a second frame body, the first frame body is connected to the second frame body, the first frame body is wrapped around the side of the back plate 3 and the display panel 21, the second frame body is located in the non-display area, and the end of the second frame body close to the center of the display area is bent toward the side close to the display panel 21.

[0102] It should be noted that the display module 2 may further include a buffer 24, which is disposed in the non-display area and along the boundary between the non-display area and the display area, and the guide plate 2222 and the pusher 2221 are located on the side of the buffer 24 away from the display area. The buffer 24 may be made of a relatively soft material such as foam, and when the explosion-proof component 22 is adjusted from the initial position to the explosion-proof position, the explosion-proof component 22 may easily press the buffer 24 and enter the explosion-proof position from the initial position to shield the display area because the buffer 24 is relatively soft.

[0103] The end of the second frame body close to the center of the display area is bent toward the side close to the display panel 21, so that the end of the second frame body is pressed against the buffer 24 on the non-display area. Under the action of the front frame 6 and the buffer 24, the non-display area can be shielded, thereby reducing the mismatch between the front frame 6 and the display panel 21, which causes the outgoing light to directly enter the wide field of view and cause the display device 1 to leak light, thereby improving the display effect of the display device 1. In addition, the second frame body is pressed against the buffer 24, so that under the action of the front frame 6 and the buffer 24, dust can be blocked from entering the interior of the display device 1. While ensuring the display effect of the display device 1, the pollution of the internal structure of the display device 1 by dust can be reduced, the maintenance cost of the display device 1 can be reduced, and the service life of the display device 1 can be extended.

[0104] In addition, a buffer structure may be provided between the display panel 21 and the plastic frame 5. Specifically, the buffer structure may be provided between the diffusion film 213 and the plastic frame 5. When the display device 1 is subjected to a small collision strength that is insufficient to cause the display panel 21 to break, the buffer structure between the display panel 21 and the plastic frame 5 may play a role in buffering and shock absorption, thereby reducing the possibility of the display panel 21 breaking when the display device 1 is subjected to a slight collision. The buffer structure may be made of the same material as the buffer member 24 described above, but is not limited thereto. The buffer structure may also be made of other materials that are different from the buffer member 24 described above and have a buffering and shock absorption effect on the display panel 21.

[0105] It should be noted that when setting up the display device 1, the end of the second frame can be pressed against the buffer 24 and the guide plate 2222 at the same time, but is not limited to this. The second frame can also be pressed only against the buffer 24. The specific details can be determined according to actual conditions. When the end of the second frame is pressed against the buffer 24, the height of the gap between the end of the second frame and the display surface can at least ensure that when the ejection structure 222 is adjusted from the initial position to the explosion-proof position, the guide plate 2222 and the explosion-proof membrane 221 can pass through the gap to enter the display area, thereby achieving complete shielding of the display area by the explosion-proof membrane 221.

[0106] The present disclosure provides a vehicle, which includes any display module 2 as described above. When the vehicle is violently impacted and the display panel 21 is shattered, the starting structure 23 can respond to the explosion vibration and move toward the thruster 2221 to start the thruster 2221 to move to an explosion-proof position, and drive the explosion-proof film 221 to shield the display area, so as to avoid the situation where debris splashes and injures people after the display panel 21 in the display module 2 is shattered, thereby improving the safety performance of the vehicle.
