Abstract：With the popularization and development of LED display in the outdoors, how to evaluate its visual quality becomes an urgent problem. In this paper, a theoretical model is established to evaluate the visual quality of LED display in CBD. Firstly, study on the working principle, physical properties and relevant standards of LED display, select 13 LED display visual effect evaluation indicators from objective and subjective aspects;then combine Delphi method with clustering algorithm, select the evaluation index set in accordance with requirements;finally, apply GA to optimize the initial judgment matrix constructed by AHP, calculate the index weight and establish the LED display visual quality evaluation model in CBD.
