A method for driving a display panel and a display apparatus applying the same are provided. A related goal is to help detect spyware programs. The link mechanism is constructed such that the first slide block and the second slide block are connected to the panel grasp portion and the panel grasp portion is moved in the panel transportation direction by individually and linearly driving the first slide block and the second slide block. The preparation method is simple, short-circle, and high effective, so it can be applied in industry, furthermore, because of no organic solvents, the method’s advantages are low cost and without pollution. The model is operable to map the input layer through a stored representation to the output layer. Also provided are novel iron complexes, pre-catalysts, intermediates, and ligands useful in the inventive polymerization system.
