Description

Technical Field

[0001] This application relates to the field of display technology, and more specifically, to a display screen and monitor with electromagnetic shielding. Background Technology

[0002] As electronic devices evolve towards higher integration and higher frequencies, various electronic components (such as processors, memory, RF modules, and power management chips) are often densely arranged around the display screen. These components generate varying degrees of electromagnetic radiation during operation. These electromagnetic waves can couple with the display screen's internal drive circuits, signal cables, and liquid crystal molecules, causing electromagnetic interference and degrading the display quality—specifically manifesting as screen flicker, increased noise, color shift, and even signal loss. This problem is particularly prominent in applications with stringent electromagnetic compatibility requirements, such as ruggedized military computers, avionics equipment, and medical instruments.

[0003] To address the aforementioned issues, existing technologies commonly employ the method of attaching a transparent electromagnetic shielding film to the surface of the display's glass substrate. This shielding film is typically made of materials with high light transmittance and good conductivity, such as a metal mesh film, silver nanowire film, or indium tin oxide transparent conductive film. To achieve a more comprehensive shielding effect, some designs attach electromagnetic shielding films to both the front and back of the glass substrate, creating a double-sided enclosure of the display screen and maximizing the attenuation of electromagnetic interference from both sides of the screen.

[0004] However, after applying double-sided electromagnetic shielding film to the glass substrate, the method of fixing it to the display screen casing becomes a new technical challenge. Currently, the industry mainly uses two fixing methods, but both have significant drawbacks: The first method is screw penetration fixing. The glass substrate is directly locked to the display screen housing with screws, which need to pass through the mounting holes in the glass substrate. Although this method provides a reliable connection and good vibration resistance, the screw penetration inevitably punctures the electromagnetic shielding film on both the front and back of the glass substrate. Once the shielding film is punctured, its integrity is compromised, the continuity of electromagnetic shielding is interrupted, and the shielding effectiveness is significantly reduced—electromagnetic interference signals can leak through these perforated areas, greatly diminishing or even completely eliminating the shielding effect. In addition, screw penetration installation also has problems such as difficulty in controlling installation accuracy and uneven wire mesh installation.

[0005] The second method is adhesive bonding. The glass substrate is bonded to the display screen housing using conductive adhesive, waterproof double-sided tape, or structural adhesive. Adhesive bonding does not involve perforation, thus avoiding any physical damage to the electromagnetic shielding films on the front and back of the glass substrate. However, adhesive bonding has serious reliability shortcomings: First, the adhesive will age and degrade due to factors such as temperature fluctuations, humidity erosion, and ultraviolet radiation during long-term use, gradually reducing the bond strength; second, in vibration environments, the adhesive interface is prone to fretting wear and fatigue failure, leading to loosening or even detachment of the glass substrate; third, conductive adhesives containing conductive fillers such as silver particles are expensive and have long curing times, and manual application results in poor consistency; furthermore, disassembly and repair are difficult after bonding, and forced disassembly will damage the shielding film and the glass substrate. Therefore, although adhesive bonding theoretically does not damage the shielding film, its connection reliability, stability, and long-term durability are insufficient to meet the stringent requirements of ruggedized electronic devices. Summary of the Invention

[0006] In view of this, this application provides a display screen with electromagnetic shielding to solve the technical problem in the prior art that the integrity of the shielding film and the fixation reliability cannot be simultaneously guaranteed when the glass substrate of the display screen is connected to the display screen housing.

[0007] This application provides a display screen with electromagnetic shielding, wherein the display screen with electromagnetic shielding includes: The display housing includes a side frame and an inner convex frame. The side frame surrounds a glass substrate mounting hole, and the inner convex frame is connected to the inner side of a first end in the thickness direction of the side frame. The inner sidewall of the side frame forms a plurality of engaging grooves in the circumferential direction. A glass substrate, wherein electromagnetic shielding films are connected to both ends of the glass substrate in the thickness direction. A locking component is movably fitted into the locking groove. The locking component has a pressure plate portion. When the locking component is in the clamping working position in the locking groove, the pressure plate portion extends into the glass substrate mounting hole, and the glass substrate is clamped between the pressure plate portion and the inner convex frame.

[0008] Furthermore, a threaded hole is provided on the side frame, the threaded hole extends from the end face of the second end in the thickness direction of the side frame toward the first end in the thickness direction of the side frame, and the threaded hole communicates with the engaging groove. The display screen with electromagnetic shielding also includes a locking screw, the locking screw is installed in the threaded hole and abuts against the engaging member to limit the engaging member to the clamping working position.

[0009] Furthermore, a limiting wall is formed on the side of the engaging groove facing the glass substrate mounting hole, and a first groove wall and a second groove wall are formed on the side of the engaging groove away from the limiting wall. The second groove wall is closer to the second end of the side frame in the thickness direction than the first groove wall. A first cavity is formed between the first groove wall and the limiting wall, and a second cavity is formed between the second groove wall and the limiting wall. The engaging component includes a rotating post, and the pressure plate is connected to the rotating post. The rotating post can only move along the thickness direction of the side frame in the first cavity, and when the engaging component is in the clamping working position, the rotating post is located in the first cavity. The rotating post can rotate in the second cavity so that the pressure plate can enter the engaging groove without extending into the glass substrate mounting hole.

[0010] Furthermore, the cross-section of the rotating column is rectangular, and the distance between the first groove wall and the limiting wall is less than the distance between the second groove wall and the limiting wall.

[0011] Furthermore, the engaging groove forms protrusions on both sides of the limiting wall, and two pressure plates are connected to the rotating column. When the engaging member is in the clamping working position, the two pressure plates extend from the protrusions on both sides of the corresponding limiting wall.

[0012] Furthermore, the second groove wall is closer to the outer side of the side frame than the first groove wall. When the engaging member is in the clamping position, the pressure plate portion is closer to the end of the first end of the side frame in the thickness direction than the rotating post, and the pressure plate portion extends perpendicular to the thickness direction of the side frame. When the rotating post is located in the second cavity, the rotating post can rotate to the placement position. In the placement position, the pressure plate portion is located in the engaging groove and extends parallel to the thickness direction of the side frame.

[0013] Furthermore, the engaging groove is formed with a third groove wall connected to the first groove wall. The third groove wall is perpendicular to the first groove wall. When the engaging member is in the clamping working position, the rotating column is engaged between the first groove wall and the limiting wall, and the pressure plate is engaged between the limiting wall and the third groove wall.

[0014] Furthermore, multiple protruding particles are provided on the wall surfaces of the first groove wall facing the limiting wall, the second groove wall facing the limiting wall, the third groove wall facing the limiting wall, the limiting wall facing the first groove wall, the limiting wall facing the second groove wall, and the limiting wall facing the third groove wall.

[0015] Furthermore, the present invention also provides a display, wherein the display includes the above-described electromagnetically shielded display screen.

[0016] Furthermore, the display includes a display housing with a screw mounting hole, and the locking screw passes through the screw mounting hole and is installed into the threaded hole to connect the display housing to the display screen housing.

[0017] The beneficial effects of the electromagnetically shielded display screen provided in this application are as follows: In the electromagnetically shielded display screen provided in this application, when the locking component is in the clamping position, the pressure plate extends from the locking groove, and the front of the glass substrate presses against the inner convex frame and the reverse edge of the glass substrate, thereby firmly clamping the glass substrate between the pressure plate and the inner convex frame. The clamping force is provided jointly by the pressure plate and the inner convex frame, which respectively abut against the front and back of the glass substrate. Throughout the entire fixing process, no parts need to pass through the glass substrate, thus completely avoiding the damage to the electromagnetic shielding film caused by traditional screw fixing methods, ensuring the integrity and continuity of the shielding film, and achieving the designed shielding effectiveness. Compared to adhesive bonding, this solution uses a purely mechanical clamping method, eliminating the problems of adhesive aging, embrittlement, and adhesion degradation. The clamping force remains constant under temperature changes, humidity changes, and strong vibration environments, significantly improving connection reliability. The locking component operates from the side of the side frame, without occupying space in the thickness direction of the display screen, which helps to achieve a thinner design. Furthermore, the installation and removal of the glass substrate does not require damage to any connectors or the substrate itself, making it highly maintainable. By setting multiple clamping parts in the circumferential direction, the glass substrate edge can be uniformly pressed at multiple points. Compared with the stress concentration of screw fixing, the multi-point clamping method makes the glass substrate more uniformly stressed, avoiding the risk of liquid crystal molecule disorder or glass breakage caused by excessive local stress, and improving the display quality of the display screen.

[0018] In a further embodiment, by setting a locking screw, after the locking component is adjusted to the clamping working position, the locking component can be firmly locked in that position, effectively preventing the locking component from accidentally coming off or shifting in a vibration environment, and further improving the connection stability and reliability of the glass substrate.

[0026] See Figures 1 to 8 This application provides a display screen with electromagnetic shielding, wherein the display screen with electromagnetic shielding includes: The display housing includes a side frame 100 and an inner protruding frame 1. The side frame 100 encloses a glass substrate mounting hole 101. The inner protruding frame 1 is connected to the inner side of the first end of the side frame 100 in the thickness direction. A plurality of engaging grooves 102 are formed in the circumferential direction of the inner sidewall of the side frame 100. The inner protruding frame 1 forms a boss structure that surrounds the glass substrate mounting hole 101. The glass substrate 2 has an electromagnetic shielding film 3 connected (bonded) to both ends in the thickness direction. The electromagnetic shielding film 3 is a transparent film. The electromagnetic shielding film 3 can play an electromagnetic shielding role against electromagnetic waves in the environment, which helps to improve the display effect of the display screen. The engaging component is movably engaged in the engaging groove 102. The engaging component has a pressure plate 4. When the engaging component is in the clamping working position in the engaging groove 102, the pressure plate 4 extends into the glass substrate mounting hole 101, and the glass substrate 2 is clamped between the pressure plate 4 and the inner protrusion frame 1.

[0027] In the electromagnetically shielded display screen provided in this application, when the locking component is in the clamping working position, the pressure plate 4 extends from the locking groove 102, and the front side of the glass substrate 2 presses against the inner convex frame 1 and against the reverse edge of the glass substrate 2, thereby firmly clamping the glass substrate 2 between the pressure plate 4 and the inner convex frame 1. The clamping force is provided jointly by the pressure plate 4 and the inner convex frame 1, which respectively abut against the front and back sides of the glass substrate 2. During the entire fixing process, no component needs to pass through the glass substrate 2, thus completely avoiding the damage to the electromagnetic shielding film 3 caused by traditional screw fixing methods, ensuring the integrity and continuity of the shielding film, and achieving the expected shielding performance. Compared with adhesive fixing, this solution adopts a purely mechanical clamping method, which eliminates the problems of adhesive aging, embrittlement, and adhesion degradation. The clamping force remains constant under temperature changes, humidity changes, and strong vibration environments, significantly improving connection reliability. The locking component operates from the side of the side frame 100, without occupying space in the thickness direction of the display screen, which helps to achieve a thin design. Meanwhile, the installation and removal of the glass substrate 2 do not require damage to any connectors or the substrate itself, making it highly maintainable. By setting multiple locking components in the circumferential direction, multiple points of uniform clamping can be achieved on the edge of the glass substrate 2. Compared with the point stress concentration of screw fixing, the multi-point clamping method makes the glass substrate 2 more uniformly stressed, avoiding the risk of liquid crystal molecule disorder or glass breakage caused by excessive local stress, thus improving the display quality of the screen.

[0028] According to a specific embodiment of this application, the side frame 100 and the inner convex frame 1 can be integrally formed structures and are both rectangular frame structures to adapt to the rectangular glass substrate 2. The inner sides of the four sides of the side frame 100 are provided with a plurality of engaging grooves 102, and each engaging groove 102 is obviously also provided with engaging components.

[0029] According to a preferred embodiment of this application, a threaded hole 103 is provided on the side frame 100. The threaded hole 103 extends from the end face of the second end in the thickness direction of the side frame 100 toward the first end in the thickness direction of the side frame 100, and the threaded hole 103 communicates with the engaging groove 102. The display screen with electromagnetic shielding also includes a locking screw 5. The locking screw 5 is installed in the threaded hole 103 and abuts against the engaging member to limit the engaging member to the clamping working position. In this embodiment, by setting the locking screw 5, after the engaging member is adjusted to the clamping working position, the engaging member can be firmly locked in this position, effectively preventing the engaging member from accidentally coming out or shifting in a vibration environment, and further improving the connection stability and reliability of the glass substrate 2. During installation, first put the engaging member into the engaging groove 102, then place the glass substrate 2 into the mounting hole and abut against the inner protruding frame 1, then operate the engaging member to make the pressure plate part 4 extend and press against the glass substrate 2, and finally tighten the locking screw 5 from the outside to press the engaging member. The entire process can be completed outside the display screen casing, making it easy to operate.

[0030] According to one embodiment of this application, a limiting wall 104 is formed on the side of the engaging groove 102 facing the glass substrate mounting hole 101, and a first groove wall 105 and a second groove wall 106 connected to each other are formed on the side of the engaging groove 102 away from the limiting wall 104. The second groove wall 106 is closer to the second end of the side frame 100 in the thickness direction than the first groove wall 105. A first cavity is formed between the first groove wall 105 and the limiting wall 104, and a second cavity is formed between the second groove wall 106 and the limiting wall 104. The engaging member includes a rotating post 6, and a pressure plate 4 is connected to the rotating post 6. The rotating post 6 can only move along the thickness direction of the side frame 100 in the first cavity, and when the engaging member is in the clamping working position, the rotating post 6 is located in the first cavity. The rotating post 6 can rotate in the second cavity so that the pressure plate 4 can enter the engaging groove 102 without extending into the glass substrate mounting hole 101. When the rotating column 6 is in the first cavity, it cannot rotate, and the orientation of the pressure plate 4 is fixed. At this time, the pressure plate 4 extends horizontally into the glass substrate mounting hole 101, pressing down on the glass substrate 2 and entering the clamping position. When disassembly is required, first loosen the locking screw 5, and push the engaging member along the thickness direction (towards the second end of the thickness direction of the side frame 100) to allow the rotating column 6 to enter the second cavity from the first cavity. Since the space in the second cavity is more spacious than that in the first cavity, the rotating column 6 can rotate freely. After rotating a certain angle (e.g., 90 degrees), the pressure plate 4 will rotate accordingly and retract into the engaging groove 102, no longer extending into the glass substrate mounting hole 101, thereby releasing the clamping of the glass substrate 2. In this embodiment, two cavities with different functions (the first cavity as a translational limiting guide cavity and the second cavity as a rotation operation cavity) are set at different thickness positions in the same groove, resulting in a highly integrated structure that eliminates the need for additional components to achieve state switching.

[0031] According to one embodiment of this application, the cross-section of the rotating column 6 is rectangular (preferably square). The distance between the first groove wall 105 and the limiting wall 104 is less than the distance between the second groove wall 106 and the limiting wall 104. In this embodiment, the width of the first cavity (the distance between the first groove wall 105 and the limiting wall 104) should be designed to match the cross-sectional dimensions of the rotating column 6, so that the rotating column 6 can only translate within it. The width of the second cavity is greater than the width of the first cavity, sufficient to accommodate the rotation of the rotating column 6 within it. When the rotating column 6 is in the first cavity, because the cavity width corresponds to the dimensions of the rectangular cross-section, the rotating column 6 is stuck between the two walls and cannot rotate, but can only slide along the thickness direction. When the rotating column 6 is pushed into the second cavity, due to the increased cavity width, the rotating column 6 obtains sufficient rotation space. It can be rotated approximately 90 degrees, causing the originally laterally protruding pressure plate portion 4 to become longitudinal or oblique, thereby retracting into the groove. When the rotating column 6 translates within the first cavity, its flat wall fits against the cavity wall, ensuring smooth guidance and preventing deviation, thus guaranteeing the accuracy of the extension position of the pressure plate 4. Furthermore, the rectangular structure allows the rotating column 6 to be pulled back into the first cavity only at a specific angle within the second cavity, ensuring that the locking component can only return to its clamping position when the pressure plate 4 is in the correct posture. This provides a certain degree of error-proofing in the assembly structure design of the display screen.

[0032] According to one embodiment of this application, the engaging groove 102 forms protrusions on both sides of the limiting wall 104. Two pressure plate portions 4 are connected to the rotating column 6. When the engaging member is in the clamping working position, the two pressure plate portions 4 extend from the protrusions on both sides of the corresponding limiting wall 104, pressing against the edge of the glass substrate 2 from two points. This dual-point clamping provides more balanced force: a single engaging member provides two clamping points to the glass substrate 2 through the two pressure plate portions 4. Compared to single-point clamping, this increases the contact area with the glass substrate 2, resulting in a more uniform distribution of clamping force, reducing the pressure per unit area, and lowering the risk of localized pressure fracture of the glass substrate 2. The simultaneous extension of the two pressure plate portions 4, like a fork structure, more stably restricts the movement and rotation of the glass substrate 2 in the plane, improving the overall rigidity of the fixation. Furthermore, even if one pressure plate portion 4 undergoes slight deformation due to extreme conditions, the other pressure plate portion 4 can still provide clamping force, thus providing a certain degree of redundant protection for the fixation of the glass substrate 2.

[0033] According to one embodiment of this application, the second groove wall 106 is closer to the outer side of the side frame 100 (i.e., away from the center of the display screen) than the first groove wall 105. When the engaging member is in the clamping position, the pressure plate part 4 is closer to the end of the first end of the side frame 100 in the thickness direction than the rotating post 6, and the pressure plate part 4 extends perpendicular to the thickness direction of the side frame 100. When the rotating post 6 is located in the second cavity, the rotating post 6 can be rotated to the placement position (at this time, the glass substrate 2 to be installed can be placed in the glass substrate mounting hole 101 and pressed against the inner protrusion frame 1). In the placement position, the pressure plate part 4 is located in the engaging groove 102 and extends parallel to the thickness direction of the side frame 100, so that the glass substrate 2 to be installed will not be interfered with by the pressure plate part 4 during the placement process.

[0034] According to one embodiment of this application, the engaging groove 102 is formed with a third groove wall 107 connected to the first groove wall 105. The third groove wall 107 is perpendicular to the first groove wall 105. When the engaging member is in the clamping working position, the rotating column 6 is engaged between the first groove wall 105 and the limiting wall 104, and the pressure plate part 4 is engaged between the limiting wall 104 and the third groove wall 107. This means that in the clamping working position, not only is the rotating column 6 itself limited by the wall surface, but the pressure plate part 4 is also clamped by the slot formed by the third groove wall 107 and the limiting wall 104, forming a double limiting of the engaging member.

[0035] According to one embodiment of this application, multiple protruding particles are provided on the wall surfaces of the first groove wall 105 facing the limiting wall 104, the second groove wall 106 facing the limiting wall 104, the third groove wall 107 facing the limiting wall 104, the limiting wall 104 facing the first groove wall 105, the limiting wall 104 facing the second groove wall 106, and the limiting wall 104 facing the third groove wall 107. These protruding particles can be hemispherical, conical, or pyramidal protrusions, and can be formed on the corresponding wall surfaces by casting, machining, or chemical etching. The protruding particles increase the contact friction between the corresponding wall surfaces and the engaging parts, helping to prevent the engaging parts from fretting and slipping in a vibrating environment, thus enhancing the reliability of locking.

[0036] In addition, see Figures 10 to 12 This application also provides a display, wherein the display includes the above-mentioned electromagnetically shielded display screen, which may be a stand-alone computer monitor, an all-in-one monitor, an industrial control screen, a vehicle-mounted display screen, or an avionics display screen, etc.

[0037] According to a preferred embodiment of this application, the display includes a display housing 200, which has a screw mounting hole 201. A locking screw 5 passes through the screw mounting hole 201 and is installed into a threaded hole 103 to connect the display housing 200 to the display screen housing. In this embodiment, the same set of locking screws 5 simultaneously achieves two functions: locking the locking components and connecting the display housing 200 to the display screen housing. This greatly simplifies the overall structure, reduces the types and quantities of parts, and lowers material costs and assembly time. Installers only need to perform one tightening operation to simultaneously lock the internal locking components and connect the external housing, significantly improving production line assembly efficiency. Furthermore, using the same set of screws for internal and external connection results in a shorter and more direct force transmission path, stronger overall structural rigidity, and more stable relative positions between components.

[0038] In other embodiments, the display housing 200 and the display screen housing may be connected by additional screws instead of sharing the locking screw 5.

[0039] It should be noted that the above embodiments only illustrate preferred embodiments of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting this application. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of this application, such as combining different features in various embodiments, and these should all fall within the protection scope of this application.
