First  the necessity of gray level correction is analyzed. Then  the gray level correction algorithm model is constructed according to the principle of latest squares approximation. Next  realization steps are described in accordance with this constructed algorithm model. Finally  this algorithm is implemented in a LED display panel  whose resolution is 128128. Experimental results show that this algorithm is able to reduce the deviation obviously during grayscale rendition and the problem of gray level deformation can be resolved perfectly because the linear relation between image data after correcting and gray level is good which satisfies the linear characteristic of LED display panel. 2010 IEEE.
