LED screen, or light-emitting diode screen, is an electronic display device that presents images, videos and other information by controlling the display mode of semiconductor light-emitting diodes. These tiny light-emitting diodes, as basic pixels, can quickly respond to electrical signals, emit light of different colors and brightness, and then combine into colorful pictures.

LED screens have a wide range of applications. In the field of advertising and media, large outdoor LED billboards on both sides of the street attract the attention of passers-by with their high brightness, large size and dynamic display effects, becoming a powerful tool for brand promotion. In terms of transportation, information display screens at airports and stations update flight and train information in real time to facilitate passengers' travel. In stage performances, LED screens create a realistic scene atmosphere and bring an immersive visual experience to the audience. In sports events, LED screens around the stadium are used to play exciting replays, scores, etc., to enhance the atmosphere of on-site viewing.

Globally, many countries occupy an important position in the field of LED screen production. China is one of the best. With a complete industrial chain, a large industrial scale and continuous technological innovation, it leads the world in LED screen manufacturing. There are many screen manufacturers in China. Old companies such as Leyard, which was founded in 1995, have rich and diverse products, including small-pitch LEDs, conventional LEDs, etc. A series of solutions based on products are widely used in smart display, smart lighting and other fields. Unilumin has R&D centers in China, Japan and the United States, and has a 400,000 square meter LED display intelligent manufacturing base, providing high-quality LED display and lighting solutions for global customers. The rising screen manufacturers include Shenzhen Feiyue Technology, which has four production bases in Guangxi, Sichuan, Shenzhen and Jiangxi, and its products are sold at home and abroad.

From the market situation, the LED screen market is showing a booming trend. With the continuous advancement of technology and the gradual reduction of costs, its market demand continues to grow. Whether in developed or developing countries, the application of LED screens is constantly expanding, and the market scale is steadily expanding. Many companies have invested in this field, and the competition is becoming increasingly fierce, which is driving the continuous improvement of product quality and performance.

In the new development direction, on the one hand, LED screens are moving towards higher resolution, higher brightness and wider color gamut to provide clearer and more realistic visual effects. On the other hand, flexible LED screens have become a hotspot for research and development. Their bendable and foldable features provide more possibilities for creative design and special scene applications, such as wearable devices, special-shaped displays, etc. In addition, smart interconnection is also one of the trends. LED screens are combined with Internet of Things technology to achieve remote control, real-time content updates and other functions, further improving user experience.
