Abstract

The invention provides an LED display screen data read-back control system. The LED display screen data read-back control system comprises a first device, a control card and an LED display screen. Thefirst device receives the screen display setting parameters and the display content and sends the parameters and the content to the control card, the control card drives the LED display screen to display according to the display information, and a file receiving module is arranged in the control card. The control card recognizes the display content and the screen parameters of the LED display screen to form the read-back data and sends the read-back data to the file receiving module, the first device sets an independent storage area in a memory of the first device in response to entering a read-back mode and is used for storing the read-back data obtained from the file receiving module of the control card, and the read-back data at least comprises the display content and the screen parameters of the corresponding LED display screen, so that through the bidirectional communication between the control card and the display control device, and by compiling and reversely analyzing the dotmatrix data of the LED display screen, the multiplexing of the display content data and the screen parameters is achieved, and the simple and efficient use of the display screen control card is achieved.

Description

technical field [0001] The invention relates to the technical field of display driving of LED display screens, in particular to a data readback control system of LED display screens. Background technique [0002] During the use of LED displays, especially those used in outdoor advertisements, exhibition halls, etc., the screen parameters and program settings (displayed content, text, and their editing and arrangement methods) are determined by the installation / commissioning personnel on site. After installation and debugging, for example, by setting various parameters on the mobile phone or computer, the edited screen parameters and programs are loaded to the display screen through the package module through the display control card, and various debugging is completed, and finally delivered to End user to use and operate display. [0003] However, end users generally only change the text during use, and do not perform other complex operations, such as the arrangement of tex...
