Description

Technical Field

[0001] The utility model relates to the field of LED display technology, in particular to an LED display screen. Background Art

[0002] LED display is a device that uses light-emitting diodes (LEDs) to display text, graphics, images and other information. It has the advantages of high brightness, energy saving and long life, and is widely used in many fields.

[0003] LED display screens are composed of multiple light-emitting diodes, and these LED modules are arranged in a dot matrix to form images. Each LED module is usually composed of several LED lamp beads, which can release light and form pixels when current is applied to display images and video signals.

[0004] The power supply for LED display screens and backlight modules is generally provided by the side panels, which are circuit boards. The side panels contain many electrical components. In actual use, in order to avoid damage and detachment of the electrical components on the side panels, a layer of protective film will be covered on the side panels. The protective film is bonded to the side panels with glue. When separating the wiring of the LED light strips, users need to tear off the protective film before operating the electrical components on the side panels. After the operation is completed, the protective film cannot be well bonded to the side panels due to insufficient viscosity. At this time, if additional glue is added, the electrical components on the side may be damaged. Utility Model Content

[0005] In view of this, the present invention aims to solve the deficiencies in the prior art, and its main purpose is to provide an LED display screen to solve the problem that the protective film cannot be well connected to the side plate again after the protective film is torn off.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: a display screen, including a display screen and a side panel connected to the display screen, wherein a first coating and a second coating are respectively provided on two sides of the side panel, and the first coating and the second coating are detachably connected through a limiting component; when separated, the abutting end of the first coating is separated from the limiting end of the second coating.

[0007] Furthermore, the limiting assembly includes a first magnetic plate disposed on the first coating and a second magnetic plate disposed on the second coating. When the first coating is in contact with the second coating, the first magnetic plate is adsorbed to the second magnetic plate.

[0008] Furthermore, the limiting assembly also includes insertion rods arranged at equal intervals on the first magnetic plate, and insertion holes arranged at equal intervals and embedded in the second magnetic plate, the abutment end is located at the end of the insertion rod, and the limiting end is located in the insertion hole.

[0009] Furthermore, the first coating is located on the front side of the side plate, the adhesive surface of the second coating is attached to the back side of the side plate, and the limiting end is located on the opposite side of the side plate to which the second coating is attached.

[0010] Furthermore, the first covering film includes a first portion covering the electronic components on the front side of the edge plate and a second portion connected to the second covering film, and the abutting end is located at the connection between the second portion and the second covering film.

[0011] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical scheme that by respectively providing the first film and the second film on both sides of the side plate, and the first film and the second film can be connected through a limiting component, the first film can ensure its protective effect when covering the side plate, and when the electrical components on the side plate need to be processed, the first film can be easily separated from the side plate, thereby facilitating the user to repair the side plate and debug the electrical components on the side plate.

[0020] Please refer to Figure 1-3As shown, it shows the specific structure of the preferred first embodiment of the utility model, which is an LED display screen, including a display screen 10 and a side panel 11 connected to the display screen, the two sides of the side panel 11 are respectively provided with a first coating 21 and a second coating 22, the first coating 21 and the second coating 22 are detachably connected through a limit assembly 30; when separated, the abutting end a of the first coating 21 is separated from the limit end b of the second coating 22. Compared with the prior art, the protection of the side panel in the complete LED display screen is bonded to the side panel by a layer of rubber film. When torn, the rubber mold is not sticky and cannot be effectively connected to the side panel. The front and back sides of the side panels in the liquid crystal cell are both covered with a first coating 21 and a second coating 22 made of rubber. The first coating 21 and the second coating 22 cooperate with each other, and the user can remove the first coating 21 covering the electrical components on the side panel 11 to repair and debug the components on the side panel 11 without affecting the normal operation of the electrical components on the side panel 11. After the repair or debugging is completed, the first coating 21 is pulled to cover the electrical components on the side panel 11 and connected to the second coating 22 for protection.

[0021] Specifically, the display screen is an LED display screen, and the side plate 11 is electrically connected to the LED display screen through a circuit. The side plate 11 is a circuit board, and electrical components are installed on its front. The second coating 22 contains adhesive and is bonded to the back of the side plate 11. The first coating 21 does not contain adhesive and is wider than the side plate 11, so that after covering the electrical components installed on the front of the side plate 11, its side edge can still fit with the front of the side plate 11 to ensure the protective effect of the first coating 21.

[0022] like Figure 3 As shown, exemplarily, the limit assembly 30 includes a first magnetic plate 31 disposed on the first coating 21 and a second magnetic plate 32 disposed on the second coating 22. When the first coating 21 and the second coating 22 are connected, the first magnetic plate 31 and the second magnetic plate 32 are adsorbed. The first magnetic plate 31 is embedded on both sides of the first coating 21, and the second magnetic plate 32 is embedded on both sides of the second coating 22. After the first coating 21 and the second coating 22 are overlapped, the first magnetic plate 31 and the second magnetic plate 32 are adsorbed. Because the second magnetic plate 32 does not pass through the second coating 22, there is still a distance between the second magnetic plate 32 and the side plate 11, which reduces the impact of the magnetic plate on the electrical components on the side plate 11, and the back of the side plate 11 is relatively flat. After the second coating 22 is bonded to the side plate 11 by glue, the second coating 22 does not need to be torn off and has strong stability, thereby improving the stability of the first coating 21 after covering the electrical components on the front of the side plate 11, and reducing the risk of separation of the first coating 21 and the side plate 11.

[0023] like Figure 3As shown, the limiting assembly 30 also includes a plug rod 311 arranged at equal intervals on the first magnetic plate 31, and a socket 321 embedded in the second magnetic plate 32 and arranged at equal intervals. The abutment end a is located at the end of the plug rod 311, and the limiting end b is located in the socket 321. With the movement of the user or the movement of the LED display during transportation, the mutually adsorbed first magnetic plate 31 and the second magnetic plate 32 may be offset with the movement until the two are separated. For this reason, the second magnetic plate 32 is provided with a socket 321, and the plug rod 311 is fixed on the first magnetic plate 31, and the plug rod 311 can be inserted into the socket 321. After plugging, when the side plate 11 vibrates during transportation or user use, the plug rod 311 on the first magnetic plate 31 is plugged into the socket 321, and the first magnetic plate 31 and the second magnetic plate 32 are adsorbed, so as to limit the movement of the first magnetic plate 31, thereby ensuring that the first coating 21 can effectively shield the electrical components on the front of the side plate 11.

[0024] Specifically, when in use, the back side of the side plate 11 generally corresponds to the outer shell of the product. When arranging the lines, the second part 212 is allowed to contact the outer shell of the product as much as possible, so as to limit the movement of the insertion rod 311 caused by up and down vibrations and improve the stability of the first coating 21 after covering the side plate 11.

[0025] like Figure 1 As shown, illustratively, the first coating 21 is located on the front side of the side plate 11 , the adhesive surface of the second coating 22 is attached to the back side of the side plate 11 , and the limiting end b is located on the opposite side of the second coating 22 attached to the side plate 11 .

[0026] The first covering film 21 includes a first portion 211 covering the electronic components on the front of the side plate 11 and a second portion 212 connected to the second covering film 22, and the contact end a is located at the connection between the second portion 212 and the second covering film 22. When the second portion 212 contacts the second covering film 22, it is necessary to bend the side edge of the covering side plate 11. During this process, the first portion 211 is in a tight state and covers the electronic components on the side plate 11. Because the first portion 211 is in a tight state, it can prevent foreign objects from easily causing one side of the first portion 211 to tilt, thereby causing dust or some impurities to contact the electrical components and affect the use of the electrical components.

[0027] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
