[0002] With the rapid development of the electronic information industry, the demand for information display terminals is increasing rapidly. Liquid crystal displays (LCDs), due to their advantages such as small size and light weight, thinness, energy efficiency, no radiation, and ease of colorization, are widely used in information display terminals in commercial, industrial, and military sectors.

This is especially true when LCDs are used in military displays, which require normal operation in electromagnetic environments, thus placing even stricter requirements on electromagnetic compatibility. While existing technologies provide LCDs and their mounting structures that can operate normally in electromagnetic environments, such as Chinese patent application (CN201765406U), which achieves electromagnetic shielding through shielding glass and a metal front and rear panel, the shielding glass mounting structure is complex and the shielding effect is poor.

[0024] 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.
[0025] The purpose of this utility model is to provide a display panel and a display to solve the problems existing in the prior art. The installation structure of the shielding glass is simple and the shielding effect is good.
[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figures 1-5 The present invention will be further described in detail below with reference to specific embodiments.
[0027] Example 1
[0028] This embodiment provides a display panel and a display, for reference. Figures 1-5 The display panel includes: a panel body 1, a shielding glass 2, and conductive components. The panel body 1 is made of conductive material and has a first groove 3. The shielding glass 2 includes a protective glass 21, a conductive shielding layer 22, and a glass substrate 23 arranged sequentially. The area of the protective glass 21 is smaller than that of the conductive shielding layer 22, and the projection of the protective glass 21 onto the conductive shielding layer 22 is located inside the conductive shielding layer 22. The shielding glass 2 is placed within the first groove 3, and the glass substrate 23 of the shielding glass 2 is closer to the bottom of the first groove 3 than the protective glass 21. The conductive components are continuously arranged along the circumference of the shielding glass 2. The inner ring of the conductive component is circumferentially connected to the portion of the conductive shielding layer 22 extending out of the protective glass 21, and the outer ring of the conductive component is connected to the panel body 1 outside the shielding glass 2. The display panel provided by this utility model has a simple installation structure for the shielding glass 2, good shielding effect, and the panel body 1 is made of conductive material, specifically, it can be a metal material or other materials, such as semiconductor materials. The shielding glass 2 includes a protective glass 21, a conductive shielding layer 22, and a glass substrate 23 arranged sequentially. By making the area of the protective glass 21 smaller than that of the conductive shielding layer 22, and ensuring that the projection of the protective glass 21 onto the conductive shielding layer 22 is located inside the conductive shielding layer 22, the conductive shielding layer 22 is exposed circumferentially on the shielding glass 2. Conductive components can be directly connected to the conductive shielding layer 22, and the conductive shielding layer 22 is connected to the panel body 1 through conductive components. Continuous electromagnetic shielding is formed in the space between the shielding glass 2 and the panel body 1 in the circumferential direction. Furthermore, the shielding glass 2 is placed within the first groove 3, resulting in a simple installation structure and good shielding effect.
[0029] In some embodiments provided by this utility model, the display panel further includes a pressure plate 5, which presses the conductive component and the shielding glass 2 into the first groove 3, and the circumferential edge of the pressure plate 5 is fixedly connected to the panel body 1. By pressing the conductive component into the first groove 3 of the panel body 1 with the pressure plate 5, the structure is simple, it is easy to press the conductive component, and the structure of the pressure plate 5 is simple and easy to process.
[0030] In some embodiments of this utility model, the conductive component includes a first conductive rubber ring 41, which is continuously arranged circumferentially along the shielding glass 2. A second groove is formed circumferentially on the inner side of the first conductive rubber ring 41. The portions of the conductive shielding layer 22 and the glass substrate 23 extending out of the protective glass 21 are connected to the inner wall of the second groove. The outer side of the first conductive rubber ring 41 is connected to the bottom and side wall of the first groove 3. By setting the conductive component as the first conductive rubber ring 41, and connecting the first conductive rubber ring 41 to the conductive shielding layer 22 and the glass substrate 23, the shielding glass 2 can be prevented from being damaged under vibration by the first conductive rubber ring 41, thus forming continuous electromagnetic shielding and giving the shielding glass 2 higher safety.
[0031] In some other embodiments, the conductive element includes a second conductive rubber ring 42 and a conductive metal ring 43. The conductive metal ring 43 is continuously arranged along the circumference of the shielding glass 2. One side of the inner ring of the conductive metal ring 43 is circumferentially connected to the portion of the conductive shielding layer 22 extending out of the protective glass 21, and the outer ring of the conductive metal ring 43 is circumferentially connected to the panel body 1 outside the shielding glass 2. The second conductive rubber ring 42 is continuously arranged along the circumference of the shielding glass 2, and one side of the second conductive rubber ring 42 is connected to the other side of the inner ring of the conductive metal ring 43. The other side of the second conductive rubber ring 42 is connected to the pressure plate 5. By providing the conductive metal ring 43 and the second conductive rubber ring 42, the inner ring of the conductive metal ring 43 is connected to the conductive shielding layer 22, and the outer ring of the conductive metal ring 43 is connected to the panel body 1, forming a continuous electromagnetic shield from the conductive shielding layer 22 to the panel body 1. The second conductive rubber ring 42 also conducts electricity under the pressure of the pressure plate 5, so that the conductive shielding layer 22, through the conductive metal ring 43 layer, the second conductive rubber ring 42, the pressure plate 5, and the panel body 1, also forms a continuous electromagnetic shield. Under the action of the two layers of electromagnetic shielding, the electromagnetic shielding effect is better and the electromagnetic shielding is more difficult to fail. Moreover, the overall electromagnetic shielding structure is simple and easy to implement.
[0032] In some embodiments provided by this utility model, the display panel further includes a sealing member 44. One side of the sealing member 44 is circumferentially connected to the glass substrate 23, and the other side of the sealing member 44 is circumferentially connected to the bottom of the first groove 3. The sealing effect between the first groove 3 and the shielding glass 2 can also be achieved by the sealing member 44. With one side of the sealing member 44 connected to the glass substrate 23 and the other side of the sealing member 44 connected to the bottom of the first groove 3, the structure is simple, easy to process, and can play a good sealing role. Compared with using conductive rubber, the cost is lower, which can save costs.
[0033] In some embodiments of this utility model, the pressure plate 5 is made of conductive material and is fixed to the panel body 1 by screws. Specifically, the pressure plate 5 can be made of metal or other materials, such as semiconductor materials. In this embodiment, the pressure plate 5 is made of metal. The metal pressure plate 5 is easy to conduct electricity. Even if the first conductive rubber ring 41 fails to form a good contact surface with the panel body 1 or the conductive metal ring 43 breaks, the metal pressure plate 5 can still connect with the panel to form electromagnetic shielding, making the electromagnetic shielding less prone to failure. Furthermore, the use of a high-strength metal material for the pressure plate 5 can also provide better protection for the structure inside the shielding glass 2. Moreover, the screw fixing method is simple and easy to process. Other fixing methods, such as welding or snap-fit, can also be used.
[0034] In some embodiments of this invention, the protective glass 21, the conductive shielding layer 22, and the glass substrate 23 are fixedly connected. This fixed connection can be achieved using adhesive bonding. In other embodiments, the protective glass 21, the conductive shielding layer 22, and the glass substrate 23 can be formed into an integral structure through high-temperature pressing, preventing scratches that could cause gaps in the electromagnetic shielding layer due to separate installation of the protective glass 21, the conductive shielding layer 22, and the glass substrate 23.
[0035] In some embodiments provided by this utility model, the conductive shielding layer 22 is a metal mesh layer or a metal coating layer. The metal mesh is preferably copper wire; the metal coating layer can be made of materials such as silver, copper, or ITO (indium tin oxide). The metals of the metal mesh and the metal coating layer can also be other metals that enable the shielding glass 2 to have excellent light transmittance and electrical conductivity as a whole in the form of a mesh or a coating layer.
[0036] In some embodiments provided by this utility model, the shielding glass 2 is transparent, that is, the shielding glass 2 allows light to pass through. Specifically, in use, the light transmittance of the shielding glass 2 needs to reach more than 70% so that the user can better observe the objects inside the electromagnetic shielding area inside the panel body 1 through the shielding glass 2.
[0037] Example 2
[0038] This embodiment provides a display, including: a display panel, a back cover, and a liquid crystal display screen as described in Embodiment 1; the back cover is sealed to the panel body 1 and forms a closed space, and is made of a conductive material; the liquid crystal display screen is disposed within the closed space. The back cover is made of a conductive material, specifically, it can be a metal material or other materials, such as semiconductor materials. Due to its structure, the liquid crystal display screen is susceptible to various electromagnetic interferences, which severely affect the quality of the displayed image and may even prevent it from functioning properly. Installing the liquid crystal display screen within the electromagnetic shielding space formed by the display panel and the back cover allows the liquid crystal display screen to function normally and ensures image quality. Furthermore, it has good waterproof and shockproof performance, is easy to transport, and can even be used in some extreme environments.
[0039] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
