About LED Display and Application

LED is a commonly used light-emitting device that releases energy and emits light through the recombination of electrons and holes. It can efficiently convert electrical energy into light energy. It has the advantages of high energy efficiency, strong monochromaticity, small size, and long life. It is widely used in display, lighting and other scenarios.
Before the development of LED display technology, the mainstream display technologies in the market were LCD and DLP. Since the earliest popular single-color and double-color LED display screens, LED display technology has gone through 5 technical stages, including single-color and double-color LED display screens, full-color LED display screens, and small-pitch LED display screens based on smaller-sized light-emitting chips, Mini LED and Micro LED, driven by the continuous iteration of design, manufacturing, and packaging technology. The downstream application scenarios have also expanded from outdoor advertising screens and door head screens to indoor ultra-large and ultra-wide display screens, theaters, televisions, transportation and more scenarios.

With the continuous deepening of global informatization and the continuous innovation of display technology, display has become one of the main channels for information transmission, and its downstream application fields are very wide. As one of the main display means, LED display screens are widely used in performing arts stages, monitoring and scheduling, competitive events, exhibitions, commercial advertisements, virtual shooting, celebrations, conferences, TV broadcasts, information release, creative display, smart cities and other fields. The typical application scenarios of LED display screens are introduced as follows:
(1) Performing Arts Stage
In recent years, with the advancement of LED display technology, in professional theater performances, literary evenings, concerts, music festivals and other indoor and outdoor entertainment performances, LED display screens and other performing arts equipment have become more and more important as a unique means of artistic display, and have become an indispensable part of artistic expression in performance activities.
(2) Monitoring and Scheduling
In the field of monitoring and scheduling, display control is mainly used for continuous acquisition, clarity processing, multi-signal source splicing, and low-loss transmission of video images. The technical scope of the monitoring and scheduling field is wide, involving modern computer technology, integrated circuit application technology, network control technology, video processing and transmission technology, and software technology, and ultimately all information is displayed on the display screen.
(3) Competitive Events
In the era of monochrome and dual-color LED display screens, the role of LED display screens in sports events was limited to displaying simple information such as scores and athlete names. With the development of LED display technology, the application of LED display in the field of sports events is becoming more and more extensive. Specific application scenarios include sports video walls, display screens around the stadium, and central hanging display screens. These new screen applications can meet the needs of long-distance viewing of sports events, ensure that the audience obtains clear and vivid color images, and can provide a variety of functions such as classic game shot playback, real-time broadcast, background images, etc.
(4) Exhibition display
Exhibition display application scenarios include exhibitions and exhibitions. Thanks to the advancement of display technology, modern exhibition display activities have evolved from visitors passively receiving exhibition information in the past to interactive viewing experience. As an advanced information dissemination hardware device, LED display screen has the characteristics of large display area and rich visual effects. It is a combination of media and high-tech display technology. Moreover, LED display screen is not just a display device. It also has the characteristics and advantages of media devices such as television. It also has a larger creative space and a wider three-dimensional space for communicating with the audience. It can meet personalized needs, greatly improve the exhibition effect, fully attract the audience's attention, and enhance the viewing experience.
(5) Commercial advertising
Traditional flat static advertising has the disadvantages of small amount of information transmitted, limited static display effect, and high content update cost. LED display screens can achieve high-quality video playback. With their visual effects, they can effectively increase the amount of information transmitted. In addition, they have the advantages of low maintenance costs and fast content updates. In recent years, their popularity in the advertising and media industry has increased significantly.
(6) Virtual shooting
In recent years, small-pitch LED screens have penetrated into the radio and television industry market, and have moved from simple terminal displays, studio background screens, and stage performance screens to the "higher requirements" and "production-level" virtual shooting field. Compared with traditional green screen technology, virtual shooting technology integrates LED display screens with virtual camera systems, spatial positioning systems, and real-time rendering systems. It uses digital virtual images as "scenes" to directly replace "non-massively reused set construction", saving on-site resources and time; actors perform directly in the virtual environment, which makes them feel more involved, and the shooting efficiency and effect are better. In terms of meeting the high-standard customization of film and television, the combination of LED display screen technology and virtual shooting has great potential.
