First  introduce the three development stages of the LED display panel. Then  the realization progress of the transitional compensation algorithm is described in detail after elaborating the principle of transitional compensation. Finally  the algorithm is emplaned in a LED video control system to control the LED display panel whose display area is 1280960  and which is spliced by 3020 LED modules whose size are 6432. Experimental results show that this algorithm is able to reduce non-uniformity of LED display images from 29.3% before correcting to 0.95%. (2012) Trans Tech Publications  Switzerland.
