Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid crystal display technology, specifically to a liquid crystal display structure that facilitates the replacement of the backlight film. Background Technology
[0002] The backlight paper of an LCD screen is used to improve the uniformity and optical performance of the backlight. Traditional backlight paper is fixed to the back of the screen by adhesive. When replacing it, it needs to be torn off from the corner, which is prone to damage due to uneven pulling force, increasing the difficulty of replacement.
[0003] The lack of an efficient and damage-resistant backlight paper replacement structure in existing technologies affects maintenance efficiency. Utility Model Content
[0004] In view of the shortcomings of the prior art, this utility model provides a liquid crystal display structure that facilitates the replacement of the backlight film, solving the problem of replacing the backlight paper of the liquid crystal display. The four corners of the backlight paper can be quickly torn open by the easy-tear adhesive, thereby avoiding damage to the backlight paper.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a liquid crystal display structure that facilitates the replacement of backlight film, comprising a display screen and a backlight paper, wherein the backlight paper is fixed to the back side of the display screen by an adhesive method, and a tear-off sticker is fixed to the back side of the backlight paper, wherein the tear-off sticker is arranged in an X shape, and the four corners of the X shape are fixed to the four corners of the backlight paper.
[0006] Furthermore: the back side of the backing paper is fixed with two paddles on both sides, the length of the paddles exceeds half of the side of the backing paper, and the paddles are fixed in the middle of the backing paper.
[0007] Furthermore: extension pieces are fixed on both sides of the lever, and the extension pieces are fixed at the connection between the lever and the backlight paper.
[0008] Furthermore, the four corners of the tear-off sticker are flush with the periphery of the backlight paper.
[0009] Furthermore, the width of the paddle is greater than the edge thickness of the backlight paper.
[0010] Furthermore, the end edges of both the extension piece and the paddle are rounded.
[0011] This invention provides a liquid crystal display structure that facilitates the replacement of the backlight film. Compared with the prior art, it has the following advantages:
[0012] The X-shaped easy-tear adhesive allows the backlight paper to detach simultaneously from all four corners, avoiding single-point tearing damage; the pry bar and extension bar increase the contact area for tearing, further preventing damage, significantly improving the efficiency of backlight paper replacement and reducing maintenance difficulty.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4 This utility model provides a technical solution: a liquid crystal display structure that facilitates the replacement of backlight films; specifically, it consists of a backlight paper 2 and a display screen 1. The backlight paper 2 is fixed to the back side of the display screen 1 by adhesive. The backlight paper 2 improves the uniformity and optical performance of the backlight source, thereby enhancing the display effect. This is existing technology and will not be described in detail here. When the backlight paper 2 is damaged, it needs to be replaced. The traditional method for replacement is to tear open the corners of the backlight paper 2 and then pull it off completely. However, tearing open the corners of the backlight paper 2 often requires considerable effort. If the backlight paper 2 is torn open only at one corner over a certain period of time, it will be damaged due to uneven pulling force, which increases the difficulty of replacing the backlight paper 2. This design fixes a tear-off sticker 3 to the back of the backlight paper 2. The tear-off sticker 3 is set in an X shape, and the four corners of the X shape are fixed to the four corners of the backlight paper 2. When the backlight paper 2 is torn off, the tear-off sticker 3 is pulled upward to detach the corners of the backlight paper 2 from the display screen 1. The tear-off sticker 3 can detach the four corners of the backlight paper 2 from the display screen 1 at the same time. This can avoid the backlight paper 2 from being damaged when it is torn and pulled, thereby improving the efficiency of replacing the backlight paper 2.
[0020] A paddle 4 is fixed on both sides of the back side of the backing paper 2. The length of the paddle 4 is set to exceed half of the side of the backing paper 2. After tearing the four corners of the backing paper 2, the backing paper 2 can be torn directly through the paddle 4. The width of the paddle 4 makes it easy to pull the backing paper 2, further avoiding the backing paper 2 from being torn.
[0021] Extension pieces 5 are fixed on both sides of the lever 4. The extension pieces 5 are fixed at the connection between the lever 4 and the backlight paper 2. The extension pieces 5 further increase the contact length with the backlight paper 2, thereby increasing the pulling length and further preventing the backlight paper 2 from being damaged when pulled and torn.
