Abstract

The invention discloses an LED display method. The LED display method comprises the steps that S1, a display controlling single-chip microcomputer receives data transmitted by a master control microcomputer of an LED display screen; S2, a master control program converts the data into patterns displayed by the screen and stores the patterns into a display memory; S3, the content of the display memory is converted into the scanning content according to a corresponding relation between the scanning sequence and the screen, and the data is outputted to a data latch used for controlling a single LED module; and S4, the data in the latch is scanned finally, and the screen is refreshed. The LED display screen comprises a control system, a driving system and a display device. The LED display screen is easy to install, a display unit board or a display unit box is adopted, and a required display screen size can be assembled at will according to user requirements and requirements of an application place, people only need to add new units or disassemble a certain unit in the system according to requirements if the system scale is required to be expanded or reduced, the system integrity is not affected, and installation and maintenance are facilitated.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to an LED display method. Background technique [0002] With the discovery of science and technology, in recent years, LED electronic display screen has attracted people's attention as a high-tech product. It can display or loop text, graphics and image information in real time. It has many advantages such as rich display methods, strong ornamental value, convenient display content modification, high brightness, stable display and long life. It is widely used in commercial advertisements and sports competitions. , traffic information reports and many other fields. [0003] The core technology of the LED display is mainly concentrated in the controller. At present, most asynchronous display screens use 8-bit or 16-bit microcontrollers. Due to the limitations of the processing speed, architecture, addressing range, and peripheral interface resources of the microproc...
