Description

Technical Field

[0001] The invention relates to LED display screen technology, and in particular to a structure for optimizing the display effect of a right-angle display screen and a display screen fixing device. Background Art

[0002] With the development of technology, the advancement of LED technology has promoted the development of LED display screens since the 1990s. Initially, LED display screens were mainly monochrome or dual-color, and were mainly used for text information release. With the development of technology, full-color LED display screens have gradually become popular, and their rich colors and high brightness make the display effect more vivid and realistic. LED splicing display screens have developed on this basis. Through the splicing of multiple modules, larger-size displays can be achieved to meet the needs of information display of different scales. LED splicing display screens are usually composed of multiple LED display modules. Each LED splicing display screen uses high-brightness LED lamp beads to ensure clear display of content under various lighting conditions. At the same time, high contrast enhances visual impact. The life of LED lamp beads is up to tens of thousands of hours, which can significantly reduce maintenance costs. Advanced control systems ensure the stability and reliability of the display. In addition, LED splicing display screens can be spliced ​​and combined according to needs to achieve displays of different sizes and shapes, adapting to the needs of large-scale venues. The block design makes installation easy, and the intuitive control interface simplifies the operation and maintenance process.

[0003] Due to the various advantages of LED splicing display screens, today's LED splicing display screens are widely used in commercial advertising, conferences and exhibitions, cultural entertainment, and public information release. In commercial advertising, it displays brand image and product information with high definition and brightness. In conferences and exhibitions, it serves as the main display platform to provide high-quality display effects. In cultural and entertainment activities such as theaters and concerts, LED splicing display screens serve as stage backgrounds, presenting colorful visual effects. In public places such as airports and railway stations, it is used to publish public information such as flight information and train schedules, making it convenient for the public to obtain real-time information.

[0004] A common challenge in the use of LED splicing display screens is the gap problem of screen splicing. Although the existing splicing technology has been able to achieve very narrow borders, there will still be visible seams and black edges between adjacent screens when splicing at a certain angle, especially at right angles. These seams not only affect the overall aesthetics, but may also interfere with the display effect, especially when displaying fine images or high-definition videos. To solve this problem, the industry has adopted a variety of methods to reduce the width and visibility of the seams. For example, by improving the frame structure and splicing technology, the LED screen modules can be made to fit more closely, thereby reducing the width of the seams. In addition, some high-end LED display screens use special sealing technology and filling materials to try to hide the seams, but these methods often only partially solve the problem and cannot completely eliminate the impact of the seams. With the development of technology, new materials and technologies may appear in the future to further reduce or even eliminate the seams between spliced ​​screens. For example, the research and development of flexible LED display screens may provide new possibilities for seamless splicing. At the same time, software algorithm optimization, such as image edge smoothing and brightness adjustment at seams, may also reduce the impact of seams on display effects to a certain extent. However, the current LED splicing display screens cannot completely hide the seams, and the use of new technologies is costly. Summary of the invention

[0005] The purpose of the present invention is to provide a structure for optimizing the display effect of a right-angle display screen, so as to solve the problem of black edges at the seams of right-angle spliced ​​display screens in the prior art.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: a structure for optimizing the display effect of a right-angle display screen, comprising a display component, wherein the right-angle joint of the display component covers a light guide component, wherein the light guide component comprises a light guide cover plate and a fixing plate arranged on the inner surface of the light guide cover plate, wherein the light guide cover plate comprises a transparent substrate, and a light guide glass coating is arranged on the outer surface of the transparent substrate.
