The correction method use a 33 correction coefficients matrix to reshape the pulse width of each LED. To calculate the correction coefficients  a linear system is established  which includes a color CCD and a LED display. And a correction algorithm is introduced based on the color CCD. This algorithm describes the relationships of the main color components of a LED  when the gray level of a LED is increasing or decreasing  the three main color components would change according to the correction coefficients. The results shows that the correction based on this algorithm improved the performance of LED displays. (2012) Trans Tech Publications  Switzerland.
