Algorithm of Reducing the Non-uniformity of Images in LED Display Panel1

For the purposes of reducing the non-uniformity of images in LED display panel further, propose an algorithm. First, analyze the causes of the problem which images in LED display panel have shortcomings of the non-uniformity of images. Second, introduce the development course of the correction techniques which are used to reduce the nonuniformity of images. Simultaneously, point out the ground that location correction must be carried out. Third, for the example of a LED display panel which is spliced by modules, construct the algorithm model. Forth, describe the realization steps of the algorithm in accordance with this constructed model. Finally, this algorithm is implemented in a LED display panel, whose resolution is 640×480. Experimental results show that this algorithm is able to reduce the non-uniformity of images obviously.
