Abstract

The invention relates to a singlechip network LED display system adopting a singlechip and a network communication technique of the singlechip, wherein a unit display plate is provided with the singlechip and is provided with the intelligent functions and the communication ability, a separated display storage area which separately completes display scanning and separately completes the communication and the collection of displaying data with a master control board, which can integrally form a display screen and also can be respectively arranged in different positions, a central control board completes the communication with a computer, and saves pictures which need to be displayed and are set by the computer, the central control board divides each of the pictures transmitted by the computer to each of display unit plates according to the collocating condition of the unit plates, and respectively transmits divided pictures to the collocated unit plates through another communication interface for displaying by the unit plates, and the central control board completes the replacement of the pictures and the display mode. The system has the beneficial effects that various free combination of display screens, in particular to the free combination of the unit plates, and can be arranged in different positions for realizing the synchronous display.

Description

technical field [0001] The invention relates to an LED display system, in particular to an LED display system which adopts a single-chip microcomputer and the network communication technology of the single-chip microcomputer to realize the independent work and coordinated work of the LED display screen. Background technique [0002] LED display is a widely used display screen. Generally, the display screen adopts centralized control row and column scanning, and is completed by hardware circuit. Its shortcomings require professional debugging and installation. Therefore, both indoor and outdoor display screens require professionals to guide and debug on site, and cannot be freely combined. The data on the communication line is transmitted in parallel at high speed, and generally requires computer real-time communication processing. Realize communication and store data. Same problem exists. Contents of the invention [0003] In order to solve the above problems, the presen...
