Title:
METHOD, DEVICE, AND SYSTEM FOR SETTING CONNECTION OF LED DISPLAY SCREEN USING TWO-DIMENSIONAL CODE
Document Type and Number:
WIPO Patent Application WO/2022/062148
Kind Code:
A1
Abstract:
A method, device, and system for setting the connection of an LED display screen (30) using a two-dimensional code. The method comprises: displaying a special test image for the connection mode, specific positions commonly corresponding to several box bodies (31) being serial numbers of output data interfaces of an LED processor (11) corresponding to the box body (31) and internal cascade numbers of the data interfaces (S110); taking a photo of the whole LED display screen (30), and obtaining data link topology positions of the box bodies by means of the serial numbers of the output data interfaces and the internal cascade numbers of the data interfaces (S120); associating the data link topology positions with the relative physical positions of the box bodies (31) in the whole LED display screen (30) to obtain connection mode data of the LED display screen (30), and generating a two-dimensional code sequence (S130); and reading and transferring the data to an LED control device (10) (S140). The method has the beneficial effects of being efficient and accurate, and saving load resources.
