[0002] Existing visual large - screen design tools are centered around a component editing platform. Designers entering the platform can directly drag and edit components. After the design is completed, various data sources can be directly connected on the platform. Human eye visual characteristics are the decision - making starting point for display system design. It not only has a direct impact on the selection of main display parameters of the display medium such as screen size, ambient brightness, and data rate, but also has a decisive impact on the ergonomic design of the display system such as character size and content layout. In existing visual large - screen designs, there is usually an emphasis on the richness and aesthetics of visual presentation effects, lacking attention to human - factor engineering design. In design practice, due to the lack of consideration of factors such as device parameters and human eye visual characteristics in the early stage, the design prototypes of visual large - screens often need to be repeatedly adjusted according to the on - site display effects in the later stage, resulting in a low design acceptance efficiency.
