Research in measuring and evaluating method of LED visual display panel is presented. Both subjective and objective facts should be considered to evaluate efficiently the main parameters of LED panel so as to make a conclusion to LED panel display quality.Through the analyzation of the indispensable parameter in the LED panel display quality,the research method is determined.On account of subjective perception on the scheme of the watching and detection experiment,the research emphatically focus on as follows:the establishment of simple appraising way,the model of chroma space,perceptive stimulative algorithm,analysis of the parameters ect.Aimed at nonstandard complication of LED quality evaluation ,this paper presents a simplified measuring and evaluating theory for LED visual image quality evaluation based on physiology.For verification the correctness of the theory,the measurement tests of various LED display panel have been done,and it is proven that it resolves many problems arised in LED measurement and evaluation.
