Improved Algorithm of LED Display Image Based on Composed Correction

In order to enhance the display result of the LED display image, an improved algorithm of LED display image based on composed correction is proposed. Firstly, the correction principle and the development status of the current correction technologies of the LED display image is introduced, and the two main correction technologies are analyzed. Secondly, the theory of composed correction is proposed by constructing a mathematical model. Thirdly, this algorithm is achieved in VHDL which is one of hardware description language, and verified in an experimental platform. Experimental results show that this algorithm is able to enhance the display result of the LED display image significantly.
