Description

Technical Field

[0001] This utility model belongs to the field of auxiliary masks, and specifically relates to an anti-glare and color correction auxiliary mask. Background Technology

[0002] In the field of display device applications, screen glare can interfere with visual perception, and color deviation can affect the accuracy of image display. Therefore, the demand for auxiliary devices with anti-glare and color correction functions is increasing. Currently, optical components such as anti-glare glass and polarizers are widely used in various display scenarios, using optical principles to reduce ambient light interference and regulate the polarization direction of light. Building on this, integrating multiple optical components into a shield structure forms an integrated auxiliary shield that can be directly adapted to different display devices, meeting users' needs for clear and accurate visual effects. It has significant application value in scenarios such as office work, audio-visual, and medical image viewing.

[0003] Currently, optical components such as anti-glare glass and polarizers have been successfully applied, effectively filtering ambient stray light, regulating the direction of light propagation, and improving screen visual comfort. The modular assembly design of these components allows them to adapt to display devices of different specifications, exhibiting strong versatility and compatibility. Furthermore, these optical auxiliary devices do not require complex circuit control, relying solely on pure optical principles to achieve their functions, offering advantages such as simple structure, convenient maintenance, and low operating costs.

[0004] While anti-glare glass and polarizers are now widely used and effectively filter ambient light, regulate light propagation, and improve screen viewing comfort, their modular assembly design allows them to adapt to different display devices, offering strong versatility and compatibility. However, most existing anti-glare and color correction auxiliary devices are integrated structures with fixed optical components to the frame, requiring specialized tools for assembly and disassembly, making installation cumbersome and inefficient. Some separate products have poorly designed component fixing structures with poor positioning accuracy, leading to misalignment and loosening after assembly, affecting calibration results and requiring repeated adjustments. Furthermore, the lack of a universal adaptable structure limits compatibility with display devices of different sizes, restricting their applicability. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an anti-glare and color correction auxiliary mask to solve the problems of auxiliary masks.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: An anti-glare and color correction auxiliary shield includes a shield frame. First and second mounting rods are fastened to the upper perimeter of the shield frame. AG glass is fitted inside the first mounting rods on both sides, and vertical polarizers are fitted inside the second mounting rods on both sides. The second mounting rods are embedded inside the first mounting rods on both sides. A first and second mounting groove are formed inside the upper perimeter of the shield frame. The first mounting rods are installed inside the first mounting groove, and the second mounting rods are installed inside the second mounting groove. The first and second mounting rods are fixed to the upper end of the shield frame by a fastening assembly. A protective plate is fitted to the upper surface of the vertical polarizer.

[0007] As a preferred technical solution, the fastening assembly includes a circular rod, a square block, a rotating block, a circular groove, a square groove, and a fastening slot. The first and second placement grooves have fastening slots inside. The first and second placement rods have circular grooves inside on both sides. The circular grooves have square grooves on both sides. The circular rod is slidably installed inside the circular groove. The bottom outer ring of the circular rod has square blocks integrally formed on both sides. The square blocks are fastened inside the fastening slots through the square grooves. The rotating block is fixedly installed at the upper end of the circular rod.

[0008] As a preferred technical solution, a second mounting groove is provided inside the second mounting rod on both sides, and the vertical polarizer is fixedly installed inside the second mounting rod through the second mounting groove.

[0009] As a preferred technical solution, a first mounting groove is provided inside the first mounting rods on both sides, and the AG glass is fixedly installed inside the two first mounting rods through the first mounting groove.

[0010] As a preferred technical solution, internal threaded grooves are provided on all four sides of the inner side of the protective plate and on both sides of the two second mounting rods, and bolts are threadedly connected inside the internal threaded grooves.

The diffuse reflection treatment of AG glass can effectively cope with strong light environments. Even under direct sunlight outdoors or strong indoor lighting conditions, it can significantly reduce glare interference and ensure clear visibility of the screen image. The polarization filtering function of the vertical polarizer accurately solves the problem of screen color distortion. Whether it is professional image design, video editing, or daily audio-visual entertainment and office viewing, it can present a realistic and full color effect to meet the visual needs of different scenarios. Secondly, addressing the pain point of cumbersome installation in traditional devices, this device adopts a dual fixing structure of snap-fit ​​+ threaded connection, enabling quick assembly and disassembly.

[0016] refer to Figures 1-4This embodiment of an anti-glare and color correction auxiliary mask includes a mask frame 6. A first mounting rod 2 and a second mounting rod 5 are fastened and installed around the upper circumference of the mask frame 6. AG glass 8 is installed inside the first mounting rod 2 on both sides, and a vertical polarizer 7 is installed inside the second mounting rod 5 on both sides. The second mounting rod 5 on both sides is embedded inside the first mounting rod 2 on both sides. A first mounting groove 16 and a second mounting groove 13 are opened inside the upper circumference of the mask frame 6. The first mounting rod 2 is installed inside the first mounting groove 16, and the second mounting rod 5 is installed inside the second mounting groove 13. The first mounting rod 2 and the second mounting rod 5 are fixed to the upper end of the mask frame 6 by a fastening assembly 4. A protective plate 3 is attached to the upper surface of the vertical polarizer 7.

[0017] refer to Figures 2 to 3 The fastening assembly 4 includes a circular rod 18, a square block 19, a rotating block 11, a circular groove 14, a square groove 15, and a fastening groove 17. The first mounting groove 16 and the second mounting groove 13 have fastening grooves 17 inside. The first mounting rod 2 and the second mounting rod 5 have circular grooves 14 inside on both sides. The circular grooves 14 have square grooves 15 on both sides. A circular rod 18 is slidably installed inside the circular grooves 14. Square blocks 19 are integrally formed on both sides of the bottom outer ring of the circular rod 18. The square blocks 19 are fastened to the fastening groove 17 through the square grooves 15. A rotating block 11 is fixedly installed on the upper end of the circular rod 18. During installation, the first mounting rod 2 and the second mounting rod 5 are placed into the mounting grooves respectively. The rotating block 11 at the upper end of the circular rod 18 is pressed down. The circular rod 18 drives the square block 19 at the bottom to slide down along the square groove 15. After the square block 19 is fully embedded in the buckle groove 17, the rotating block 11 is rotated to make the square block 19 and the square groove 15 offset at an angle, thereby locking in the buckle groove 17. This achieves quick fixing of the first mounting rod 2 and the second mounting rod 5, and the assembly can be completed without the aid of professional tools.

[0018] refer to Figures 1 to 3 The second mounting rods 5 on both sides have second mounting slots 10 inside. The vertical polarizer 7 is fixedly installed inside the second mounting rods 5 through the second mounting slots 10. The color correction function is completed by the vertical polarizer 7 installed in the second mounting rods 5 on both sides. The core function of the vertical polarizer 7 is to regulate and filter the polarization direction of light. The light emitted by the display device screen is mostly polarized light. When it is not filtered, the polarization direction of the light is chaotic, which will lead to a decrease in color saturation and a deviation in color reproduction. The color distortion problem is more obvious when viewed from multiple angles.

[0019] refer to Figures 1 to 2The first mounting rods 2 on both sides have first mounting grooves 9 inside. The AG glass 8 is fixedly installed inside the two first mounting rods 2 through the first mounting grooves 9. The anti-glare function is achieved by the AG glass 8 installed in the first mounting rods 2 on both sides. The full name of AG glass 8 is anti-glare glass. Its surface is treated with special frosting or chemical etching to form a uniform and dense micro-concave-convex structure. When the ambient light shines on the shield surface, traditional smooth glass will produce specular reflection. The reflected light directly enters the human eye and forms glare, interfering with the observation of the screen image. However, the concave-convex structure on the surface of AG glass 8 will convert the incident ambient light into diffuse reflection, disperse the concentrated reflected light in various directions, greatly reduce the intensity of the reflected light, and avoid strong light directly stimulating the human eye.

[0020] refer to Figures 3 to 4 The protective plate 3 has internal threaded grooves 12 on all four sides and on both sides of the two second mounting rods 5. Bolts 1 are threaded into the internal threaded grooves 12. The upper end of the first mounting rod 2 has second assembly grooves 21 on both sides. The bottom of the second mounting rod 5 has first assembly grooves 20 on both sides. The second mounting rod 5 is built on the upper end of the two first mounting rods 2 by splicing the first assembly grooves 20 and the second assembly grooves 21. The inner walls of the first assembly grooves 20 and the second assembly grooves 21 have internal threaded grooves 12 of the same specifications as the protective plate 3. The bolts 1 are threaded into the protective plate 3, the first mounting rod 2 and the second mounting rod 5 to form a threaded connection. The bolts 1 pass through the threaded grooves of the protective plate 3 and the mounting rods to form a threaded connection structure. This not only protects the vertical polarizer 7 and the AG glass 8, but also further strengthens the connection stability of the first mounting rod 2 and the second mounting rod 5, preventing the components from shifting or loosening during use.

[0021] Operating principle and advantages: The anti-glare function of the device is achieved by the AG glass 8 installed in the first mounting rods 2 on both sides. The AG glass 8 is called anti-glare glass. Its surface is treated with special frosting or chemical etching to form a uniform and dense micro-concave-convex structure. When ambient light shines on the shielding surface, the traditional smooth glass will produce mirror reflection. The reflected light directly enters the human eye and forms glare, interfering with the observation of the screen image.The uneven surface of the AG glass 8 converts incident ambient light into diffuse reflection, dispersing concentrated reflected light in various directions and significantly reducing the intensity of reflected light, thus preventing strong light from directly stimulating the eyes. In the device structure, the AG glass 8 is fixed by the first mounting slot 9 of the first mounting rod 2 and embedded in the outer layer of the shield frame 6, prioritizing the filtering of ambient light and reducing glare at the source. This lays a clear visual foundation for subsequent color correction. The color correction function is performed by the vertical polarizer 7 installed in the second mounting rods 5 on both sides. The core function of the vertical polarizer 7 is to regulate and filter the polarization direction of light. The light emitted by the display device screen is mostly polarized light, which, when unfiltered, will cause glare. The chaotic polarization direction of light can lead to reduced color saturation and inaccurate color reproduction, especially when viewed from multiple angles, where color distortion becomes more pronounced. The second mounting rod 5 is embedded inside the first mounting rod 2, and the vertical polarizer 7 is positioned behind the AG glass 8, perpendicular to the polarization angle of the light emitted from the screen. When light filtered by the AG glass 8 passes through the vertical polarizer 7, only light with the same polarization direction as the polarizer can pass through, while other chaotically polarized light is effectively filtered. This unifies the polarization direction of the light on the screen, achieving accurate color reproduction and significantly improving the color saturation, contrast, and realism of the image. The upper part of the mask frame 6 has openings around the four sides of the first... The first and second mounting slots 16 and 13 each have a pre-set snap-fit ​​groove 17. Circular grooves 14 are formed on both sides of the first and second mounting rods 5, and square grooves 15 connect to both sides of each groove. A circular rod 18 with a square block 19 is slidably installed within the circular groove 14. During installation, the first and second mounting rods 18 are placed into their respective mounting slots. The rotating block 11 at the upper end of the circular rod 18 is pressed down, causing the circular rod 18 to slide the square block 19 down the square groove 15. Once the square block 19 is fully embedded in the snap-fit ​​groove 17, the rotating block 11 is rotated, causing the square block 19 to shift at an angle relative to the square groove 15, thus locking it into the snap-fit ​​groove 17 and achieving rapid fixation of the first and second mounting rods 5. Assembly can be completed without the need for specialized tools. The protective plate 3, which is attached to the upper surface of the vertical polarizer 7, has internal threaded grooves 12 of the same specification on all four sides, the two sides of the second mounting rod 5, and the inner wall of the second mounting groove 21 of the first mounting rod 2. After the second mounting rod 5 is fitted and spliced ​​with the second mounting groove 21 at the upper end of the first mounting rod 2 through the first mounting groove 20 at the bottom, the protective plate 3 covers the surface of the vertical polarizer 7. The threaded connection structure is formed by bolts 1 passing through the threaded grooves of the protective plate 3 and the mounting rod. This not only protects the vertical polarizer 7 and the AG glass 8, but also further strengthens the connection stability between the first mounting rod 2 and the second mounting rod 5, preventing the components from shifting or loosening during use.
