METHOD FOR ACTIVATING THE CELLS OF AN IMAGE DISPLAYING SCREEN, AND IMAGE DISPLAYING DEVICE USING SAME

摘要

A method for activating the cells of an image display screen. Electric potential signals called activation signals are produced to activate the cells and to supply the current consumed by this activation. An electric potential is applied to a solenoid so as to develop the activation signals at the solenoid terminals and to cause a change in the main current in the solenoid which serves as the current consumed by the cell activation. Thus, cell activation control of the "current supply" type is effected, and is particularly suited for the delivery of large amounts of current in a short time. This may be used in image display screens such as plasma panels.
