A display screen with an anti-static structure

Abstract

This invention provides a display screen with an anti-static structure, including a liquid crystal display layer and a glass substrate bonded to the liquid crystal display layer. Silver paste conductors are disposed on the sides of the liquid crystal display layer, with one end connected to the liquid crystal display layer and the other end having an extension conductor portion. It also includes a short-circuit assembly disposed on the glass substrate, comprising a carrier film detachably connected to the glass substrate and conductive units disposed on the carrier film. The conductive units are detachably in contact with several extension conductor portions. The anti-static display screen provided by this invention, with its extension conductor portions at the ends of the silver paste conductors, short-circuits the extension conductor portions by pressing them together with conductive rods on the carrier plate and pressure plate of the conductive units in the short-circuit assembly. This releases static electricity from the liquid crystal display screen, preventing damage from electrostatic short circuits during subsequent chip assembly, thus providing good protection for the liquid crystal display screen.

Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and specifically to a display screen with an anti-static structure. Background Technology

[0002] Display screens, especially liquid crystal displays (LCDs), are widely used in various electronic devices. Their internal liquid crystal display layer and driver integrated circuits (ICs) are extremely sensitive to electrostatic discharge (ESD). During the production, assembly, testing, transportation, and subsequent module processing of displays, static charges are easily generated due to friction, induction, and other means. If these static charges cannot be released effectively and in a timely manner, they can be conducted through the wiring on the side of the screen (such as silver paste wires) to the delicate liquid crystal driver IC, causing the IC to be electrostatically damaged. This results in bright lines, dark lines, screen distortion, or even permanent damage to the display screen, leading to decreased product yield and increased production costs.

[0003] Existing LCD screens are prone to damage to the driver IC due to electrostatic short circuits, resulting in poor protection. This solution addresses this technical problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a display screen with an anti-static structure. The end of the silver paste conductor is provided with an extension conductor section. The extension conductor section is short-circuited by the conductive rod one on the carrier plate and the conductive rod two on the pressure plate of the conductive unit in the short-circuit assembly, thereby releasing the static electricity on the liquid crystal display screen and avoiding damage from electrostatic short circuits during subsequent chip assembly. This provides good protection for the liquid crystal display screen.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a display screen with an anti-static structure, including a liquid crystal display layer and a glass substrate attached to the liquid crystal display layer, wherein a silver paste conductor is provided on the side of the liquid crystal display layer, one end of the silver paste conductor is connected to the liquid crystal display layer, and the other end of the silver paste conductor is provided with an extension conductor portion;

[0006] It also includes a short-circuit assembly disposed on the glass substrate, the short-circuit assembly comprising a carrier film detachably connected to the glass substrate and a conductive unit disposed on the carrier film, the conductive unit being detachably in contact with a plurality of the extended wire portions.

[0007] The conductive unit includes a carrier plate and a pressure plate respectively disposed on the carrier film. The carrier plate and the pressure plate are made of separable and attractive magnetic material, especially soft magnetic material. A first conductive rod is disposed on the carrier plate, and a second conductive rod corresponding to the first conductive rod is disposed on the pressure plate. The extended wire portion is pressed and disposed between the first conductive rod and the second conductive rod.

[0008] The edge of the carrier film is provided with a flipping part, and the pressure plate is disposed on the flipping part.

[0009] Two conductive rods are provided, and one conductive rod is provided. The conductive rod detachably presses the extended wire portion between the two conductive rods.

[0010] A protective film is disposed on the glass substrate, and a carrier film is adhered to the protective film.

[0011] The carrier film is provided with a positioning groove plate, which can be detachably abutted against the edge of the glass substrate.

[0012] A bend line is provided between the flipping part and the carrier film.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The end of the silver paste wire is provided with an extension wire section. The extension wire section is pressed and short-circuited by the conductive rod one on the carrier plate and the conductive rod two on the pressure plate of the conductive unit in the short-circuit assembly, thereby releasing the static electricity on the liquid crystal display screen and avoiding damage from static short circuit during subsequent chip assembly. The protection effect on the liquid crystal display screen is good.

[0015] (2) The glass substrate is positioned and protected by the positioning groove plate. The silver paste wire part in the liquid crystal display layer is supported and protected by the setting of the bearing film and the flip part. The short circuit component has a good protection effect on the liquid crystal display layer and the glass substrate.

[0016] (3) Both the carrier plate and the pressure plate are made of magnets. The combination and separation of the carrier plate and the pressure plate are more convenient and quick. When in use, the combination of conductive rod one and conductive rod two is more firm and reliable, which improves the reliability of short circuit of silver paste wires, thus making the transportation of LCD screen safer and more reliable.

[0023] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0024] See Figures 1-5 A display screen with an anti-static structure includes a liquid crystal display layer 1 and a glass substrate 2 attached to the liquid crystal display layer 1. A silver paste conductor 3 is provided on the side of the liquid crystal display layer 1. One end of the silver paste conductor 3 is connected to the liquid crystal display layer 1, and the other end of the silver paste conductor 3 is provided with an extension conductor portion 4.

[0025] It also includes a short-circuit assembly 5 disposed on the glass substrate 2. The short-circuit assembly 5 includes a carrier film 51 that is detachably connected to the glass substrate 2 and a conductive unit 52 disposed on the carrier film 51. The conductive unit 52 is in detachable contact with a plurality of extended wire portions 4.

[0026] The conductive unit 52 includes a carrier plate 521 and a pressure plate 522 respectively disposed on the carrier film 51. The carrier plate 521 and the pressure plate 522 are made of separable and attractive magnetic material. A first conductive rod 5211 is disposed on the carrier plate 521, and a second conductive rod 5221 corresponding to the first conductive rod 5211 is disposed on the pressure plate 522. The extension wire part 4 is pressed between the first conductive rod 5211 and the second conductive rod 5221.

[0027] The edge of the carrier film 51 is provided with a flipping part 511, and the pressure plate 522 is provided on the flipping part 511.

[0028] There are two conductive rods 5211 and one conductive rod 5221. The conductive rod 5221 can be detachably pressed and positioned between the two conductive rods 5211.

[0029] The edge of the carrier film 51 is also provided with a hard pressure plate 53 for separating the extension wire portion 4 and the silver paste wire 3.

[0030] A protective film 6 is provided on the glass substrate 2, and a carrier film 51 is adhered to the protective film 6. Specifically, an adhesive layer is provided on the side of the carrier film 51 close to the protective film 6, and the rest of the carrier film 51 does not have an adhesive layer, so as to prevent the rest of the carrier film 51 from adhering to the liquid crystal display layer 1.

[0031] The carrier film 51 is provided with a positioning groove plate 54, which can be separated from the edge of the glass substrate 2.

[0032] A bend line 55 is provided between the flipping part 511 and the carrier film 51.

[0033] The specific working process of this utility model:

[0034] During assembly, the positioning slot plate 54 is aligned with the edge of the glass substrate 2 and clamped in place. Then, the carrier film 51 is pasted onto the protective film 6. At this time, the carrier plate 521 of the conductive unit 52 is located below the extension wire section 4. Then, the flipping part 511 is held and rotated, so that the pressure plate 522 of the flipping part 511 is attracted to the carrier plate 521. At this time, a second conductive rod 5221 on the flipping part 511 presses the extension wire section 4 between the two first conductive rods 5211. The extension wire section 4 is connected by the pressing of the first conductive rod 5211 and the second conductive rod 5221, thereby conducting the static electricity generated on the liquid crystal display screen from the silver paste wire 3 to the extension wire section 4, and finally short-circuiting through the first conductive rod 5211 and the second conductive rod 5221 to complete the static electricity release. When it is necessary to install the liquid crystal driver IC, the carrier film 51 is removed from the protective film 6, and then the carrier plate 521 and the pressure plate 522 are separated to complete the separation of the short-circuit component 5 from the liquid crystal display layer 1, realizing the effect of short-circuit static electricity release.

[0035] Furthermore, if it is necessary to separate the extension lead portion 4 from the silver paste lead portion 3, simply hold and press the hard pressure plate 53 on the flipping part 511. The hard pressure plate 53 has a cutting edge on its edge. The hard pressure plate 53 is pressed between the silver paste lead portion 3 and the extension lead portion 4. The silver paste lead portion 3 and the extension lead portion 4 are cut and separated by the pressure of the hard pressure plate 53. Thus, the extension lead portion 4 is cut and separated by the hard pressure plate 53 of the short-circuit assembly 5, and the extension lead portion 4 can be removed.

[0036] The silver paste conductor 3 has an extension conductor section 4 at its end. The extension conductor section 4 is short-circuited by the conductive rod 5211 on the carrier plate 521 and the conductive rod 5221 on the pressure plate 522 of the conductive unit 52 in the short-circuit assembly 5, thereby releasing the static electricity on the liquid crystal display screen and avoiding damage from static short circuits during subsequent chip assembly. This provides good protection for the liquid crystal display screen.

[0037] The glass substrate 2 is positioned and protected by the positioning groove plate 54. The silver paste wire 3 in the liquid crystal display layer 1 is supported and protected by the bearing film 51 and the flip part 511. The short circuit component 5 has a good protective effect on the liquid crystal display layer 1 and the glass substrate 2.

[0038] Both the carrier plate 521 and the pressure plate 522 are made of magnets. The combination and separation of the carrier plate 521 and the pressure plate 522 are more convenient and quick. During use, the combination of the first conductive rod 5211 and the second conductive rod 5221 is more firm and reliable, which improves the reliability of short circuit of the silver paste wire 3, thus making the transportation of the LCD screen safer and more reliable.

[0039] From the completion of screen production to the end customer's assembly, the short-circuit component 5 always short-circuit all signal lines, which can effectively discharge static charge generated at any stage and protect the driver IC.

[0040] With its magnetically detachable design, the removal of the short-circuit component 5 does not require direct contact with the electrical connection point. Furthermore, the physical connection is preferentially disconnected through structures such as the hard pressure plate 53, completely avoiding the risk of generating and introducing secondary static electricity during the removal process. The short-circuit component 5 is integrated with the protective film 6, featuring a compact structure that makes installation and removal simple and quick, thus improving production efficiency. The use of conductive rod clamping and magnetic attraction ensures the stability and low resistance of the short-circuit connection, resulting in significant protection.

[0041] Technical features not described in detail in this solution are based on conventional operations and general understanding of those skilled in the art, and are therefore not elaborated upon here. Technical features not described in this utility model can be implemented using existing technology, and will not be repeated here. Of course, the above description is not intended to limit this utility model, nor is it limited to the examples given above. Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of this utility model should also fall within the protection scope of this utility model.
