Description

Technical Field

[0001] The utility model relates to the field of liquid crystal displays, and more specifically, to a side-light prevention structure for a liquid crystal display. Background Art

[0002] A liquid crystal display is an active matrix liquid crystal display driven by thin film transistors. It mainly uses an electric current to stimulate liquid crystal molecules to generate dots, lines, and planes, combined with a backlight tube to form an image. IPS, TFT, and SLCD all belong to subclasses of LCD. Its working principle is that under the action of an electric field, the arrangement direction of liquid crystal molecules changes, causing the light transmittance of an external light source to change (modulation), completing the electro-optical conversion, and then using different excitations of R, G, and B primary color signals to complete color reproduction in the time domain and spatial domain through red, green, and blue primary color filter films. Ambient light is an important factor affecting the visual experience of a liquid crystal display. Under different ambient lights, the color rendering, clarity, contrast, brightness, and color saturation of the liquid crystal display will all change, thus affecting the viewing effect, and even causing visual fatigue and discomfort. Viewing in strong sunlight will cause screen reflection, resulting in a blurred and distorted image, affecting the viewing experience. Application No.: CN201520321661.4 discloses a display light shield, which includes an upper baffle and left and right baffles respectively located on both sides of the upper baffle, and further includes a positioning frame that is snap-fitted with the display. The positioning frame is connected and cooperated with the upper baffle, left baffle, and right baffle through sliding mechanisms. The utility model adjusts the upper baffle, left baffle, and right baffle through the sliding mechanisms, so that they slide to appropriate positions to block the influence of external light on the display. Moreover, the structure of the utility model is simple, and the installation and disassembly are very convenient. Its application range is also relatively wide and can be used for various displays, such as televisions, computers, medical displays, etc.

[0003] However, the above solution still has certain defects. The inventor has found through research that the angles of the three baffles in the above solution cannot be adjusted.

[0021] Please refer to Figures 1 to 4 , the present invention provides a technical solution: an anti-side-light structure for a liquid crystal display, including three C-shaped mounting bases 5, which are respectively installed at both ends and the top of one side surface of the display body 11. Each C-shaped mounting base 5 is rotatably connected to a connecting block 6, and each connecting block 6 is detachably connected to a C-shaped mounting bracket 2. A light-shielding plate 1 is rotatably connected between the inner walls on both sides of the C-shaped mounting bracket 2.

[0022] Please refer to Figure 3 and Figure 4, a plurality of uniformly distributed through holes 8 are provided on one side surface of each C-shaped mounting seat 5, a bolt 9 is inserted into each through hole 8, one end of each bolt 9 is threadedly connected to a corresponding screw hole 10, and each screw hole 10 is provided on one side surface of the display body 11.

[0023] The whole C-shaped mounting seat 5 is detachably connected to the display body 11 through the bolt 9, and the user can choose whether to install the C-shaped mounting seat 5 according to the placement environment and usage needs of the display body 11, thereby reducing the usage limitations.

[0024] Furthermore, both the top and bottom surfaces of the light shielding plate 1 are rotatably connected to the inner walls on both sides of the C-shaped mounting frame 2 through the first rotating shafts 3.

[0025] The light shielding plate 1 can rotate independently relative to the C-shaped mounting frame 2, so that the light shielding angle can be adjusted. When in use, the angle of the light shielding plate 1 is adjusted according to the actual light conditions to obtain a better light shielding effect.

[0026] Furthermore, one end of the connecting block 6 is provided with a second rotating shaft and is rotatably connected to the inner walls on both sides of the C-shaped mounting seat 5 through the second rotating shaft.

[0027] The whole connecting block 6 can drive the C-shaped mounting frame 2 and the light shielding plate 1 to rotate independently relative to the display body 11, so that it is convenient to store the light shielding plate 1 when it is not in use, avoid affecting the viewing angle of the display body 11 when there is no light shielding requirement, and reduce the limitations during use.

[0028] Furthermore, both the first rotating shaft 3 and the second rotating shaft are damping rotating shafts.

[0029] The first rotating shaft 3 and the second rotating shaft with damping structures can limit the positions of the light shielding plate 1 and the connecting block 6 without external force after adjusting their angles, ensuring the stability during use.

[0030] Furthermore, a plug-in sliding groove 7 is provided on the other end surface of the connecting block 6, a plug-in sliding block 4 is provided on one side surface of the C-shaped mounting frame 2, and the plug-in sliding block 4 is slidably installed in the plug-in sliding groove 7.

[0032] Furthermore, a matte coating is applied to each side surface of the light shielding plate 1.

[0033] The roughness of the surface of the light shielding plate 1 is improved through the matte coating, so that the light is diffusely reflected after irradiating on the surface of the light shielding plate 1, avoiding the light being reflected to the user's eyes through the light shielding plate 1 and causing discomfort in viewing.

[0034] Working principle: The three C-shaped mounting seats 5 are mounted at both ends and the top of one side surface of the display body 11 through bolts 9. Each C-shaped mounting bracket 2 is inserted into the insertion chute 7 provided on one end surface of the corresponding connecting block 6 through the insertion slider 4 to complete the installation of the light shield 1. The angle of the light shield 1 is adjusted according to the actual light conditions and usage requirements to block the side light, so as to prevent the side light from shining on the display body 11 and affecting the overall brightness of the display body 11 and generating reflection to affect the user's viewing. When the light shield 1 is not needed, the three connecting blocks 6 can be rotated to the rear side of the display body 11 through the second rotating shaft for storage, so as to prevent the light shield 1 from affecting the viewing angle of the display body 11 and reduce the usage limitations.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
