An LED display screen is a flat panel display composed of small LED module panels used to display various information such as text, images, and videos.
LED electronic displays integrate microelectronics technology, computer technology, and information processing, possessing advantages such as vibrant colors, wide dynamic range, high brightness, long lifespan, and stable and reliable operation.
LED displays are widely used in commercial media, cultural performances, sports venues, information dissemination, news releases, securities trading, etc., meeting the needs of diverse environments.
