What is Led Sign Board
LED sign is a new media advertising form, a perfect combination of new media technology and outdoor advertising release form. LED advertisements are advertising words or pictures made of light-emitting diodes. For example, the electronic large-screen advertisements that we usually see on the street or some roadsides have bright and colorful advertising words and signs. LED (Light-Emitting-Diode, meaning light-emitting diode in Chinese) is a semiconductor that can convert electrical energy into visible light. It changes the principle of tungsten filament light emission of incandescent lamps and three-primary color powder light emission of energy-saving lamps, and electroluminescence is adopted. LED panel is a display screen that displays text and images by controlling the display mode of semiconductor light-emitting diodes. LED display mainly includes graphic display and full-color display.
The development trend of LED signs
Outdoor advertising ushered in the LED era
LED full-color display is a new type of information display media that has developed rapidly in the world in the 1990s. It has a series of advantages such as strong environmental adaptability, high energy saving, long life, changeable, and environmental protection. It emits active light and has high resolution at long distances. Even at a distance of 100 meters, the visual effect is the same as watching TV at home. The technical level of my country’s LED display industry is relatively advanced. The main products and key technologies are consistent with the advanced level of the international industry, but the level of technology is relatively backward. In product standardization, overall system design, reliability, manufacturing technology, testing and testing methods There is a clear gap with the international advanced level in other aspects. With the progress of semiconductor materials and process technology and the increase in production, the performance of LED will be further improved, and the price will continue to drop. It will gradually and comprehensively enter the field of outdoor advertising.
