Abstract

In this paper, a luminance measurement model of LED display using the image sensors was constructed, and the precision problems of this model were analyzed. We analyzed the parameters of the luminance measurement model of LED display from several aspects, including the spatial distribution of luminous intensity of LEDs with different viewing angles, the LED positioning error, the aberration of the optical measurement system, and the imaging as well as noise characteristics of the image sensors. Through the simulation, the influencing factors and the rules of the precision of the luminance measurement model of LED display were discussed. The results show that the LED positioning error and the noise level of the image sensors are the main influencing factors in the measurement model.
