Abstract :
In order to ensure high quality display results of LED display panel in all kinds of ambient brightness, a dynamic nonlinear transformation algorithm is proposed. First, the implementation processes of the method of lock-up table nonlinear transformation are described, which is the traditional method of nonlinear transformation. Second, an algorithm model of dynamic nonlinear transformation is constructed. Third, the algorithm realization steps are discussed on the basis of the constructed algorithm model. Finally, the relationship between the coefficient of nonlinear transformation and ambient brightness is analyzed. Experimental results indicate, regardless of ambient brightness this algorithm is able to ensure that the contrast of LED display panel does not decrease, so the display results of LED display panel is good.
