Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to an anti-reflective liquid crystal display. Background Art

[0002] Liquid crystal display is an active matrix liquid crystal display driven by thin film transistors. It mainly uses electric current to stimulate liquid crystal molecules to produce points, lines, and surfaces to form a picture with the back light tube. IPS, TFT, and SLCD are all subcategories of LCD. Its working principle is that under the action of the electric field, the arrangement direction of liquid crystal molecules changes, the transmittance of the external light source changes (modulation), and the electro-optical conversion is completed. Then, the different excitations of the three primary color signals of R, G, and B are used to complete the color reproduction in the time domain and space domain through the three primary color filters of red, green, and blue.

[0003] However, under the irradiation of natural light and light, the traditional liquid crystal display has a reflective surface. If the natural light and light are not blocked, it will not only easily affect the user's use of the liquid crystal display, but also the reflected light will cause damage to the user's eyes when it shines into the user's eyes. At the same time, since the traditional liquid crystal display lacks a blocking structure, it cannot be used for anti-reflection. Therefore, the utility model provides an anti-reflection liquid crystal display to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an anti-reflective liquid crystal display, which can not only meet the requirements of shading and anti-reflection in different directions as needed, but also increase the shading height and improve the shading range as needed, so as to achieve better use effect.

[0010] The above technical solution is helpful to limit and fix the movable clamping frame, thereby reducing the displacement that occurs when the light-shielding and anti-reflection device is used, which leads to a decrease in the anti-reflection effect.

[0011] Furthermore, the clamping block is embedded in one of the three limiting blocks, and one end of the clamping block passes through the front end surface of the movable clamping frame;

[0013] Furthermore, a groove is provided on one side of the movable clamping frame, the groove is slidably engaged with the outer frame, and the guide roller is embedded in the groove near the lower end and embedded in the track groove;

[0014] Through the above technical solution, when in use, the movable clamping frame can be conveniently moved in the guiding direction provided by the track groove and the outer frame.

[0015] Furthermore, the No. 2 sleeve is located between the two No. 1 sleeves, the inner plate is movably embedded in the outer plate and passes through the upper end surface of the outer plate, a plurality of plug holes are opened on one side of the inner plate, and the latch is embedded in one of the plurality of plug holes;

[0016] Through the above technical solution, the inner plate can be pulled out as needed, so that the height of the entire shading mechanism can be changed, and after being pulled out, it can be fixed and used using a latch.

[0017] Furthermore, a connecting seat is fixedly provided on one side of the outer wall of the second sleeve, and the connecting seat is fixedly connected to the outer wall of the movable clamping frame;

[0018] Through the above technical solution, the entire shading mechanism is fixed on the movable clamping frame, so that the shading mechanism moves synchronously with the movable clamping frame.

[0019] Furthermore, the outer frame is composed of a semi-enclosed structure surrounded by two side plates and a top plate, and the track groove is consistent in shape with the semi-enclosed structure of the outer frame;

[0020] Through the above technical solution, the shading on both sides and the upper end can be completed, that is, the anti-reflective use requirements in three directions are met.

[0037] The shading mechanism 4 includes an inner plate 401 and an outer plate 402. A No. 1 sleeve 404 is fixedly provided at the upper end and the lower end of one side of the outer wall of the outer plate 402. A shaft column 403 is rotatably embedded between the two No. 1 sleeves 404. A No. 2 sleeve 406 is fixedly sleeved at the midpoint of the outer side of the shaft column 403. A pin 405 is embedded at the upper end of the other side of the outer wall of the outer plate 402.

[0038] Specifically, according to the above-mentioned embodiment, when the display is in use and one side or the upper end needs to be shielded to prevent reflection, the card block 6 at the front end is first pulled out. Since the limiting blocks 8 are embedded at the upper ends of both sides of the display body 2 and one side of the upper end, the front end face and one side of the rear end face of the movable clamping frame 5 are provided with through holes 11, and the card blocks 6 are embedded in the two through holes 11. When the card block 6 is pulled out, one end of the movable clamping frame 5 can be separated from the outer frame 1. At this time, a groove 10 is provided on one side of the movable clamping frame 5, and the groove 10 is slidably engaged with the outer frame 1. The guide roller 9 is embedded in the lower end of the groove 10 and is embedded in the track groove 7.
