Abstract:

The paper presents the lighting patterns and the relation between the illuminant and the illuminated surface,analyses the relation between LED packages,visual angle and luminescence intensity spatial distribution,obtains a function of LED luminescence intensity spatial distribution,and establishes a LED display panel lighting model.According to the model,the illumination distribution patterns and the unitary attenuation coefficient of LED display panel in different position of view can be obtained.

Key words: LED display panel;spatial distribution;attenuation coefficient
