Description

Technical Field

[0001] This utility model relates to the technical field of display screens, specifically to an anti-static structure for a liquid crystal display screen. Background Technology

[0002] Liquid crystal displays (LCDs) are a type of flat panel display used in televisions and computers. Their advantages include low power consumption, small size, and low radiation. LCDs utilize a liquid crystal solution in two polarizing materials; when an electric current passes through the liquid, the crystals rearrange to achieve image formation.

[0003] Chinese Patent Publication No. CN218100607U discloses an anti-static liquid crystal display screen, comprising: a display screen body and a mounting base, wherein the mounting base is disposed at the bottom of the display screen body. The display screen body is characterized by having an anti-static mechanism, which includes an electrostatic guiding film and an anti-static film. The electrostatic guiding film is adhered to one side of the display screen body, and the anti-static film is adhered to the side of the electrostatic guiding film away from the display screen body. The anti-static mechanism is used to prevent the generation of static electricity. The mounting base is provided with a height adjustment mechanism, which includes a mounting plate and a fixing frame. The mounting plate is connected to the mounting base, and the fixing frame is connected to the display screen body. The mounting plate is slidably connected to the fixing frame. The height adjustment mechanism is used to adjust the display height of the display screen body.

[0004] In the above solution, the combination of ion fan, electrostatic guiding film and antistatic film is used to neutralize the charge generated on the display screen body due to operation, thereby achieving the purpose of antistatic. However, it has the following disadvantages: the positive and negative ion flow of the ion fan will disrupt the charge balance on the surface of the antistatic film, which can easily induce secondary static electricity, resulting in the accumulation of charge on the surface of the display screen, thereby reducing the performance of the display screen. Utility Model Content

[0005] The purpose of this invention is to provide an anti-static structure for a liquid crystal display screen, in order to solve the problem that the positive and negative ion flow of the ion fan will disrupt the charge balance on the surface of the anti-static film, easily induce secondary static electricity, and thus cause the charge to accumulate on the surface of the display screen.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: an anti-static structure for a liquid crystal display screen, including a mounting frame, the mounting frame being disposed on the outer wall of the display screen body, a support frame being rotatably disposed on the bottom surface of the mounting frame, an adhesive strip being adhered to the front side of the display screen body, an anti-static film being adhered to the adhesive strip, a conductive cavity being formed between the display screen body and the anti-static film through the adhesive strip, two through holes being opened on the inner bottom surface of the mounting frame, two grounding blocks being fixed on the bottom surface of the support frame, wires being connected to the grounding blocks, and the adhesive strip being electrically connected to the grounding blocks through the wires.

[0007] Preferably, the outer wall of the mounting frame is provided with a fixing groove, and an insulating ring is fixed to the inner wall of the fixing groove.

[0008] Preferably, a mounting hole is provided on the rear side of the mounting frame, and a fan module is fixed to the inner wall of the mounting hole.

[0009] Preferably, the front side of the mounting frame has several snap-fit ​​slots, the front side of the mounting frame is provided with a light-blocking plate, and several snap-fit ​​posts are fixed on the light-blocking plate, the snap-fit ​​posts are snap-fitted with the snap-fit ​​slots.

[0010] Preferably, the adhesive strip contains metal particles.

[0011] Preferably, the grounding block adopts multi-point grounding.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Through the action of adhesive strips, anti-static film, conductive cavity, and grounding block, static electricity generated on the surface of the display screen can be guided, allowing the static electricity to be stably conducted through the wires and grounding block, effectively preventing the accumulation of static electricity on the surface of the display screen, thereby improving the performance of the display screen. The anti-static film allows the charge generated on the surface of the display screen to be evenly distributed along the film surface through a conductive network, preventing localized electric field concentration. Multi-point grounding through the grounding block effectively reduces the grounding impedance of the adhesive strip, ensuring a low impedance grounding circuit.

[0014] Second, the insulating ring prevents leakage current between the mounting frame and the equipment casing, allowing static electricity to be stably conducted through the wires under the action of the adhesive strip, thus improving the conductivity of the adhesive strip. The fan module dissipates heat generated by the display screen itself, maintaining air circulation within the mounting frame and effectively preventing heat buildup, thereby avoiding localized overheating. The light-blocking plate physically blocks ambient light (such as sunlight and indoor lighting), effectively preventing reflections or glare on the display screen, thus improving the visibility and clarity of the displayed image.

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown, an anti-static structure for a liquid crystal display screen includes a mounting frame 1, which is disposed on the outer wall of the display screen body 2. A support frame 3 is rotatably mounted on the bottom surface of the mounting frame 1. An adhesive strip 4 is adhered to the front side of the display screen body 2, and an anti-static film 5 is adhered to the adhesive strip 4. A conductive cavity 6 is formed between the display screen body 2 and the anti-static film 5 through the adhesive strip 4. Two through holes 7 are opened on the inner bottom surface of the mounting frame 1. Two grounding blocks 8 are fixed on the bottom surface of the support frame 3. Wires are connected to the grounding blocks 8. The adhesive strip 4 and the grounding blocks 8 are electrically connected through the wires. The adhesive strip 4 contains metal particles, and the grounding blocks 8 adopt multi-point grounding.

[0022] During use, when static charge is generated on the surface of the display body 2 due to friction or electric field induction, the charge will fill the conductive cavity 6. The antistatic film 5 achieves lateral diffusion of charge through its conductive network, avoiding excessive local charge density that could lead to dielectric breakdown. At this time, the metal particles dispersed in the conductive strip 4 will form a permeation conductive network, guiding the charge gathered at the edge of the antistatic film 5 to the preset grounding wire through a low-impedance path. Finally, the charge is transmitted to the grounding block 8 through the wire, guiding the static electricity to the ground.

[0023] Through the action of the adhesive strip 4, antistatic film 5, conductive cavity 6, and grounding block 8, the static electricity generated on the surface of the display screen body 2 can be guided, allowing the static electricity to be stably conducted through the wires and grounding block 8, effectively preventing the accumulation of static electricity on the surface of the display screen body 2, thereby improving the performance of the display screen body 2. The antistatic film 5 can also distribute the charge generated on the surface of the display screen body 2 evenly along the film surface through the conductive network, preventing local electric field concentration.

[0024] like Figures 1-4 As shown, the outer wall of the mounting frame 1 is provided with a fixing groove 9, and an insulating ring 10 is fixed to the inner wall of the fixing groove 9. The rear side of the mounting frame 1 is provided with a mounting hole 11, and a fan module 12 is fixed to the inner wall of the mounting hole 11. The front side of the mounting frame 1 is provided with several snap-fit ​​grooves 13, and a light-blocking plate 14 is provided on the front side of the mounting frame 1. Several snap-fit ​​posts 15 are fixed on the light-blocking plate 14, and the snap-fit ​​posts 15 are snap-fitted with the snap-fit ​​grooves 13.

[0025] During use, the insulating ring 10 prevents leakage current between the mounting frame 1 and the equipment casing, allowing static electricity to be stably conducted through the wires under the action of the adhesive strip 4, thereby improving the conductivity of the adhesive strip 4. The fan module 12 dissipates the heat generated by the display screen body 2, maintaining air circulation within the mounting frame 1 and effectively preventing heat accumulation, thus avoiding localized overheating. The light-blocking plate 14 physically blocks ambient light (such as sunlight and indoor lighting), effectively preventing reflections or glare on the display screen body 2, thereby improving the visibility and clarity of the displayed image.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
