Description

Technical Field

[0001] The utility model belongs to the technical field of displays, and particularly relates to an anti-screen cracking structure applicable to liquid crystal modules. Background Art

[0002] Liquid crystal module displays are widely used display devices, which are composed of a liquid crystal panel, a backlight module, a driving IC, a control IC, etc. They have the advantages of small size, low power consumption, fast response speed, rich colors, etc., and can work at low temperatures, so they are widely used in various fields. Liquid crystal module displays achieve the display effect through the physical properties of liquid crystal molecules. The backlight module provides light sources, and the driving and control ICs are responsible for adjusting the brightness and voltage, thus presenting clear and vivid images and texts. Their characteristics such as high resolution, programmability, and low latency further enhance the user experience.

[0003] In the traditional liquid crystal module structure design, in order to prevent the screen cracking problem of the liquid crystal panel caused by external forces, the method of setting support structures around the liquid crystal panel is often adopted. However, these traditional methods often have problems such as overly simple support structures and insufficient impact resistance, which easily lead to screen cracking of the liquid crystal panel when subjected to a large impact, affecting the service life of the product and the user experience. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an anti-screen cracking structure applicable to liquid crystal modules in order to solve the problems such as overly simple support structures of common liquid crystal modules, insufficient impact resistance, and easy screen cracking.

[0005] The utility model realizes the above purpose through the following technical solutions: It includes a backplane and a liquid crystal panel, and also includes four corner support members. The four corner support members are all L-shaped and formed by hard materials. A plurality of diagonal braces are connected between the two legs of the corner support member. The diagonal braces are formed by soft materials. The corner support members are installed at the four corners inside the backplane. The four corners of the liquid crystal panel are placed on the corner support members, and the four corners of the liquid crystal panel and the backplane are separated by the diagonal braces.

[0006] Further, inclined surfaces are provided at the ends of the two legs of the corner support member. A support bar is provided between the two corner support members and is formed by hard materials. The two ends of the support bar are inclined surfaces and are closely attached to the inclined surfaces of the two legs of the corner support member. The support bar is adhesively bonded to the inner side of the backplane.

[0007] Further, the corner support member and the diagonal brace are injection molded by a dual-material integrated mold.

[0008] Further, shock-absorbing strips are pasted on the four sides of the back of the liquid crystal panel.

[0009] Furthermore, limiting grooves are provided on both feet of the corner support member, and the shock-absorbing strip is embedded inside the limiting grooves.

[0010] Beneficial effects: The utility model is reasonably designed and has the following beneficial effects:

[0011] 1. In the solution of the utility model, by arranging four L-shaped corner support members between the back plate and the liquid crystal panel, the stability and impact resistance of the overall structure are effectively enhanced. The corner support members are formed of a hard material, ensuring their firm and stable characteristics, while the diagonal tension strips are made of a soft material with good flexibility, providing sufficient elastic buffering for the liquid crystal panel and greatly reducing the risk of screen cracking at the corners of the liquid crystal panel due to external forces.

[0012] 2. In the solution of the utility model, shock-absorbing strips are pasted on the four sides of the back of the liquid crystal panel, and this design further enhances the impact resistance of the liquid crystal panel. The shock-absorbing strips can effectively absorb and disperse external forces, reduce the impact on the liquid crystal panel, and thus reduce the possibility of screen cracking.

[0017] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments.

[0018] Combined with Figures 1 to 3 A screen cracking prevention structure applicable to a liquid crystal module shown in the figure includes a back plate 1 and a liquid crystal panel 2, and further includes four corner support members 3. The four corner support members 3 are all L-shaped and are formed of a hard material. A plurality of diagonal tension strips 4 are connected between the two feet of the corner support member 3. The diagonal tension strips 4 are formed of a soft material. The corner support members 3 are installed at the four corners inside the back plate 1. The four corners of the liquid crystal panel 2 are placed on the corner support members 3, and the four corners of the liquid crystal panel 2 are separated from the back plate 1 by the diagonal tension strips 4.

[0019] Among them, inclined surfaces are provided at both ends of the two feet of the corner support member 3. A support bar 5 is provided between the two corner support members 3 and is formed of a hard material. Both ends of the support bar 5 are inclined surfaces and are closely attached to the inclined surfaces of the two feet of the corner support member 3. The support bar 5 is adhesively bonded to the inner side of the back plate 1.

[0020] The corner support member 3 and the stay bar 4 are injection molded by a dual-material integrated mold.

[0021] Shock-absorbing strips 6 are pasted on the four sides of the back surface of the liquid crystal panel 2. The shock-absorbing strips 6 can effectively absorb and disperse external forces, protecting the liquid crystal panel 2 from impact damage.

[0022] Limit grooves 7 are provided on the two feet of the corner support member 3. The shock-absorbing strips 6 are embedded inside the limit grooves 7, which not only improves the shock-absorbing effect but also ensures that the shock-absorbing strips 6 will not fall off or shift when subjected to impact.

[0023] Working principle: During the use of the present utility model, the four L-shaped corner support members 3 provide stable support for the liquid crystal panel 2. These support members are formed of a hard material and can withstand large external force impacts, thus effectively preventing the liquid crystal panel 2 from deforming or being damaged when subjected to impact; the stay bar 4, as a soft material connecting the two feet of the corner support member 3, has good flexibility. When the liquid crystal panel 2 is subjected to an external force impact, the stay bar 4 can deform and absorb part of the impact energy, thereby reducing the direct impact on the liquid crystal panel 2. This elastic buffering effect greatly reduces the risk of screen cracking at the corners of the liquid crystal panel 2 due to external forces; the shock-absorbing strips 6 pasted on the four sides of the back surface of the liquid crystal panel 2 further enhance its impact resistance. The shock-absorbing strips 6 can effectively absorb and disperse external force impacts, dispersing the impact force over a larger area, thereby reducing the local impact on the liquid crystal panel 2 and further reducing the possibility of screen cracking.
