| In this dissertation, the research and design of outdoor full-color LED display system have been discussed in detail from the human vision characteristics and chromatics, the anti-gamma correction the adjustments of luminance, contrast and color based on the relation between the characteristics of LED luminescence and the feature of human vision have been analyzed in detail. In this dissertation the data distribution mechanism, the transform of data format and the driver technology of bit-plane breakaway have also been researched. The circuit noise and digital pulse interference have been restrained effectively through the system analysis. Through many experiments, the processing of the LED display screen whose refresh rate is 60Hz and gray-grade is 256 has been realized. |
