An objective characterization method for large area flicker of plasma display panel is proposed. A measuremental setup based on a photo diode and a luminance meter, was built to record the light behavior quickly and accurately. Based on model of critical flicker frequency calculation for cathode ray tube, an analytical model was built to predict the perceived large area flicker seriousness level based on the measured light behavior. The output of the analytical model had a coefficient of correlation as high as 0.98 with perception experimental results. The measuremental setup and the simulative model enable objective evaluation for large area flicker of plasma displays, it is consistent with experimental results. It helps with plasma display panel design optimization and industrial standardization.
