Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal displays, and particularly relates to a liquid crystal display with an angle wrapping and protecting effect. Background Art

[0002] A liquid crystal display is a common flat panel display technology, which is widely used in various electronic devices, such as televisions, computer monitors, smart phones, and tablet computers. Working principle of the liquid crystal display: Liquid crystal molecules: The liquid crystal display uses special liquid crystal molecules as the display medium, and these molecules can change their orientation under the action of an electric field. Liquid crystal layer: The liquid crystal molecules are placed between two parallel transparent electrodes to form a liquid crystal layer. When a voltage is applied to the electrodes, the change in the electric field will cause the orientation of the liquid crystal molecules to change. Polarizer: There are usually polarizers above and below the liquid crystal layer. One polarizer allows light in a specific direction to pass through, and the direction of the other polarizer is perpendicular to it, so that the polarization direction of the light passing through the liquid crystal layer can be adjusted according to the orientation of the liquid crystal molecules. Backlight: Most liquid crystal displays require a backlight, usually an LED backlight, to provide brightness and contrast behind the display. Main features: Low power consumption, thinness, high definition, and color performance: Modern liquid crystal displays can provide good color performance and a wide color gamut, suitable for various image and video display requirements.

[0003] In the prior art, when the four corners of some liquid crystal displays and the display body are impacted, only the display body can bear this impact force. For a liquid crystal display, if the impact force is small, the display can bear it, but for a slightly larger impact force, it may cause certain damage to the liquid crystal display body, the tiny parts inside the display, and the electronic components inside the display. Some liquid crystal displays with an angle wrapping and protecting effect, although having a certain impact resistance function, for a large impact force in a single direction, it will directly cause the outer frame of the display to collide with the outer frame of the buffer structure. Even due to the spring fixed on the buffer structure, according to the spring's rebound effect, the outer frame of the display will rebound in the opposite direction and collide again, causing a secondary impact on the display. Content of the Utility Model

[0004] The purpose of the utility model is to provide a liquid crystal display with an angle wrapping and protecting effect, which can buffer the front impact force and side impact force received by the liquid crystal display to a certain extent, thereby protecting the liquid crystal display body, the tiny parts inside the liquid crystal display, and the electronic components inside the liquid crystal display, and can effectively prevent rigid collision and rebound collision between the two frames under the action of a large impact force in a single direction, which may damage the liquid crystal display.

Sliders are slidably connected to both sides of the bidirectional sliding grooves. A return spring is fixedly connected to the left side of the slider. The other end of the return spring is fixedly connected to a fixed block. Buffer springs are fixedly connected to the upper left and right sides of the fixed block. The upper ends of the buffer springs are fixedly connected to a clamping groove. A second frame body is clamped below the clamping groove on the lower right side. First buffer layers are fixedly connected to the middle parts of the four circumferences inside the second frame body. A second buffer layer is fixedly connected to the right side of the first buffer layer on the left side. Brackets are fixedly connected to the lower left and right sides of the second frame body. Third buffer layers are fixedly connected to the upper left and right sides of the second frame body.

[0006] According to the liquid crystal display screen with a corner wrapping and protecting effect, above the slider is located inside the fixed block, and the slider is slidably connected to the fixed block.

[0007] According to the liquid crystal display screen with a corner wrapping and protecting effect, the clamping groove on the lower right side abuts against the inner wall of the second frame body, and the clamping groove is slidably connected to the second frame body.

[0008] According to the liquid crystal display screen with a corner wrapping and protecting effect, the second buffer layer is located between the first frame body and the second frame body, and the second buffer layer does not contact the first frame body.

[0009] According to the liquid crystal display screen with a corner wrapping and protecting effect, the material of the first buffer layer is silica gel.

[0025] Referring to Figures 1-5 , in an embodiment of the present utility model, a liquid crystal display screen with a corner protection effect includes a liquid crystal screen body 1.

A return spring 5 is fixedly connected to the left side of the sliders 4, and the other end of the return spring 5 is fixedly connected to the fixed block 6. Buffer springs 7 are fixedly connected to the upper left and right sides of the fixed block 6. The upper ends of the buffer springs 7 are fixedly connected to a clamping groove 8. A second frame 9 is clamped below the clamping groove 8 on the lower right side. The clamping groove 8 on the lower right side abuts against the inner wall of the second frame 9, and the clamping groove 8 is slidably connected to the second frame 9. First buffer layers 10 are fixedly connected to the middle parts of the four circumferences inside the second frame 9. The material of the first buffer layer 10 is silica gel. A second buffer layer 11 is fixedly connected to the right side of the first buffer layer 10 on the left side. The material of the second buffer layer 11 is polyethylene sponge.
