Abstract
This invention relates to a driving method for reducing the dynamic image false contour for display panels, and more particularly, to a driving method that is useful in the display technique of plasma display panels in this method, the erase period of the driving signal is separated and a display electrode and a data electrode are utilized to compose a pair of erasing signals and thus realize the separated erasing signal periods. The present invention further provides a signal process circuit device of the driving method which comprises a plurality of scanning IC's including a plurality of connected transistor switches in order to achieve the division of erasing signal period in the mentioned driving method, It can prevent the abrupt changes of image brightness and the distortion of dynamic image false contour and effectively improve the moving picture quality when the dynamic image is moving. In addition, due to the reduced requirement for the address data memory, the cost on the circuit device can be effectively reduced by using this method, due to the reduced requirement for the address data memory
