The principle is to display text, pictures, animations, videos and other information content by dimming LED dot matrix lamp beads. LED display screens have the characteristics of high brightness, uniform light emission, low power consumption, long life, strong weather resistance, and good reliability. In recent years, they have rapidly become the leader in the field of indoor and outdoor flat panel displays and are widely used in information display fields such as outdoor transportation, billboards, and public display screens. The existing display screen data transmission method is to receive video source data, compress and transmit it, and then decompress it to convert it into a data format that can be displayed on the display screen. However, as people become more familiar with the use of LED display systems and pursue display effects, more and more large-scale display data such as pictures are added to the display data, resulting in: the amount of communication data is getting larger and larger, and the communication time is getting longer and longer. The limited method of compression and decompression not only limits the data transmission efficiency but also cannot guarantee the data quality, reducing the practicality and user experience. In order to solve the above problems, this embodiment discloses a data transmission method for an LED display screen.
