Description

Display screen parameter debugging method, system and medium Technical Field The present invention relates to the field of display screen detection technologies, and in particular, to a method, a system, and a medium for debugging parameters of a display screen. Background The LED display screen (LED DISPLAY) is a flat panel display, and consists of a plurality of LED modules, and is used for displaying various information such as characters, images, videos and the like. The display screen is a planar display screen formed by LED lattice modules or pixel units. The display screen integrates microelectronic technology, computer technology and information processing, and has the advantages of bright color, wide dynamic range, high brightness, long service life, stable and reliable operation and the like. The display screen is widely applied to commercial media, cultural performance markets, stadiums, information dissemination, news release, securities trade and the like, and can meet the requirements of different environments. The installation height of the display screen and the complexity of the service site situation may require at least 2 or more personnel to complete the debugging and maintenance work. On the one hand, in the initial installation and debugging stage of the display screen, the traditional debugging and maintenance method needs one person to operate, the other person observes the effect and feeds the result back to the debugging personnel, and the method is repeated for a plurality of times until the maintenance is completed. The traditional debugging method has the limitation of ‌ of manual operation, relies on experienced technicians to adjust parameters, has long debugging period, has human error risk, causes inconsistent parameters due to subjective judgment difference of different technicians on 'optimal display effect', and is difficult to meet the synchronous debugging requirement of large-scale display projects (such as spliced walls). And the problem ‌ of equipment compatibility exists in the automatic debugging process, namely, the protocol difference exists in display screen driving chips of different manufacturers, the traditional debugging tool cannot automatically identify various driving schemes, and a plurality of sets of debugging parameter templates are required to be prepared for different equipment.
