Description

technical field [0001] The invention relates to LED display technology, in particular to an LED display screen control technology for converting LCD display parameters into LED display parameters. Background technique [0002] In recent years, flat panel display technology has been continuously improved. Among them, the standardization of LCD communication interfaces, multiple signal sources, and a more mature market mechanism. With the continuous improvement of the design and manufacturing level of LED display technology, LED display screens are gradually used in production and life. With their unique display media, LED displays can be used in some application fields, such as large-area, all-weather, high-brightness and The field of ultra-high-brightness display shows its advantages, but the large-scale application also brings out some defects of LED display technology. The technology is not yet mature, the standard has not been fully established, and there is no signal sou...
