Description

Technical Field

[0001] The utility model relates to the field of display technology, and more specifically, to a borderless LED display screen. Background Art

[0002] With the rapid development of display technology, LED display screens have been widely used in advertising, information release, stage background and other fields due to their advantages such as high brightness, low power consumption and long life. However, traditional LED display screens have some limitations, especially in application scenarios that pursue higher visual experience and design aesthetics;

[0003] Traditional LED display screens are usually composed of multiple display modules with obvious physical borders between these modules, which causes the screen to be segmented when displaying images, affecting the integrity and immersion of the viewing experience. In addition, the edges of the screen are often rough, which easily introduces interference from ambient light and reduces the contrast and clarity of the screen.

[0004] To address these issues, the industry has explored various technical solutions, such as reducing the visible border by narrowing the physical gap between modules, or employing specialized optical designs to enhance the edge effects of the screen. While these methods have improved display quality to a certain extent, they still have limitations, such as high cost, complex installation, and difficult maintenance. Utility Model Content

[0005] In order to solve the above technical problems, the technical solution of the present invention is as follows: a borderless LED display screen, including a display unit, the display unit is rectangular, and one side of the display unit is provided with multiple locking parts, and the other side of the display unit relative to the locking part is recessed with multiple locking grooves. The multiple display units are spliced and locked together by the cooperation of the multiple locking parts and the multiple locking grooves, thereby ensuring the alignment accuracy during splicing, thereby ensuring the uniformity and integrity of the display picture, and reducing the visual faults between the display units. Electromagnets are symmetrically built into the side walls on both sides of the display unit. When the electromagnets are attracted, additional fixing force is provided, thereby enhancing the connection stability between the display units.

[0006] Furthermore, the display unit includes an optically transparent layer, a physical display layer and an adjustment circuit board, and the optically transparent layer, the physical display layer and the adjustment circuit board are stacked in order from top to bottom, the first layer is the optically transparent layer, which is used to optimize the transmittance of light and reduce the sense of boundary between the display unit and the display screen, the second layer is the physical display layer for displaying images and video content, and the third layer is the adjustment circuit board, which is used to process input signals and control the physical display layer to generate display images and video content. A micro-lens array is integrated on the edge of the optically transparent layer to optimize the propagation direction and transmittance of light and reduce the sense of boundary between the display unit and the display screen.

[0007] Furthermore, the locking piece and the locking groove are integrated into the adjustment circuit board. The locking piece and the locking groove are electrically connected to realize signal transmission between the two adjustment circuit boards, thereby ensuring the consistency of display effects between the spliced display units, enhancing the visual effect, and improving the user's viewing quality. Signal interaction is directly completed through the locking piece and the locking groove, reducing the need for additional wiring and reducing wiring complexity.

[0008] Furthermore, an outer surface of the physical display layer is provided with LED lamp beads and a semicircular medium arranged in a matrix, and the LED lamp beads are encapsulated in the thin and transparent semicircular medium to protect the LED lamp beads and provide uniform light output.

[0009] Furthermore, a plurality of LED controllers are arranged in a matrix on the surface of the adjustment circuit board opposite to the other outer surface of the physical display layer facing away from the LED lamp beads. The LED controllers are used to control the lighting of the LED lamp beads. The LED controllers control the driving circuit on the adjustment circuit board according to a pre-set program, so that the LED array emits light regularly, thereby allowing the display unit to display text, graphics and videos. The LED controllers also have the advantages of easy wiring and simple use, and can achieve light change effects such as jump and gradient according to actual needs.

[0010] Compared with the prior art, the beneficial effects of the technical solution of the present invention are as follows: the present invention designs a borderless LED display screen, which splices and locks multiple display units together through the cooperation of multiple locking pieces and multiple locking grooves, ensuring the alignment accuracy during splicing, thereby ensuring the uniformity and integrity of the display picture, and reducing the visual discontinuity between the display units. Electromagnets are symmetrically built into the side walls on both sides of the display unit. When the electromagnets are attracted, additional fixing force is provided, thereby enhancing the connection stability between the display units; secondly, the micro-lens array integrated at the edge of the optically transparent layer can further optimize the propagation direction and transmittance of light, enhance the overall visual effect, and make the edge of the screen look smoother and borderless; through the electrical connection between the locking piece and the locking groove, signal transmission between the two adjustment circuit boards is realized, ensuring the display effect between the spliced display units is consistent, enhancing the visual effect, and improving the user's viewing quality. Signal interaction is directly completed through the locking piece and the locking groove, reducing additional wiring requirements and reducing wiring complexity.
