Lighting Control System of Display Wall Based on Visual Comfort Abstract: In order to solve the problem that the poor lighting effect of display wall leads to the decline of viewers' visual experience, an intelligent lighting control system for display wall based on visual comfort is designed. The display wall intelligent lighting control system, POS optimization fuzzy adaptive PID algorithm, PSO algorithm optimization parameters PID initial value are discussed and verified. The results show that the system is simple in design and comprehensive in function, which can better display the contents of the display wall and greatly enhance the visual experience of viewers.
