What is an LED display?
2024-11-28
LED display is a flat panel display that displays information by controlling semiconductor light-emitting diodes (LEDs). It consists of many small LED module panels, each module contains multiple LED light-emitting diodes, which display different colors and patterns by controlling the on and off of current.

Historical background
The earliest LED display can be traced back to the 1970s, when low-luminous efficiency GaP, GaAsP homojunction red, yellow, and green LEDs were used, mainly for indicator lights, numbers, and text displays.
Main features
High brightness: The brightness of the LED display can reach more than 1000cd/m², and it can be clearly displayed even in strong light environments.
High reliability: It uses imported large-scale integrated circuits with high reliability and stability.
Long life: The life of the LED display is usually more than 20,000 hours.
High resolution: It has 1024-4096 grayscale control, and the display color can reach more than 16.7M, with clear and realistic colors and strong three-dimensional sense.
Wide viewing angle: The viewing angle is large, usually 120°～170° (horizontally) and 160°～220° (vertically). Good waterproof performance: Adapt to outdoor environment and have waterproof function. Strong impact resistance: Able to withstand large physical impact without damage.
Application scenarios
LED display screens are widely used in finance, taxation, industry and commerce, post and telecommunications, sports, advertising, factories and mines, transportation, education system, stations, docks, airports, shopping malls, hospitals, hotels, banks, securities markets and other fields. It can be used not only in indoor environments, but also in outdoor environments, and has advantages that projectors, TV walls, and LCD screens cannot match. In summary, LED display screens play an important role in many fields with their high brightness, long life, and high reliability.
