Description

Technical Field

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

[0002] With the development of technology, LED technology has driven the development of LED displays since the 1990s. Initially, LED displays were primarily monochrome or two-color, used primarily for text information dissemination. As technology evolved, full-color LED displays gradually became popular, their rich colors and high brightness making displays more vivid and lifelike. LED videowall displays have evolved from this foundation, combining multiple modules to achieve larger displays, meeting the needs of information displays of varying scales. LED videowall displays are typically composed of multiple LED display modules. Each LED videowall uses high-brightness LED lamps, ensuring clear display in all lighting conditions. High contrast enhances visual impact, and the LED lamp lifespan reaches tens of thousands of hours, significantly reducing maintenance costs. Advanced control systems ensure display stability and reliability, and LED videowall displays can be customized to create displays of various sizes and shapes, adapting to the needs of large-scale displays. Their modular design makes installation easy, and their intuitive control interface simplifies operation and maintenance.

[0003] Due to their various advantages, LED video walls are now widely used in commercial advertising, conferences and exhibitions, cultural entertainment, and public information dissemination. In commercial advertising, they showcase brand images and product information with high clarity and brightness. At conferences and exhibitions, they serve as the primary display platform, providing high-quality presentations. In cultural and entertainment events such as theaters and concerts, LED video walls serve as stage backdrops, presenting a rich and colorful visual experience. In public places like airports and train stations, they are used to disseminate public information such as flight information and train schedules, providing convenient access to real-time information.

[0004] In the use of LED splicing display screen, a common challenge is the gap problem of screen splicing. Although the existing splicing technology has been able to achieve very narrow frame, but in the splicing of a certain angle, especially the right angle splicing, there will still be visible joints and black edges between adjacent screens. These joints not only affect the overall aesthetic, but also may interfere with the display effect, especially when displaying fine images or high-definition videos. In order to solve this problem, the industry has taken a variety of methods to reduce the width and visibility of the joint. For example, by improving the frame structure and splicing technology, the LED screen module can be made to fit more closely, thereby reducing the width of the joint. In addition, some high-end LED display screens use special sealing technology and filling materials to try to hide the joint, but these methods can only partially solve the problem and cannot completely eliminate the influence of the joint. With the development of technology, new materials and technologies may appear in the future to further reduce or even eliminate the joint 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, optimization of software algorithms, such as image edge smoothing and brightness adjustment at the joint, may also reduce the impact of the joint on the display effect to some extent, but the current LED splicing display screen cannot completely hide the joint, and the use of new technology is costly. Practical new type content

[0005] The purpose of the present application is to provide a structure for optimizing the display effect of a right-angle display screen, in order to solve the problem of black edges at the joint of a right-angle splicing display screen in the prior art.
