Abstract:
Provided is a driving method for a plasma display panel capable of prolonging a life span of the plasma display panel and improving luminous efficiency thereof by preventing an accumulation of positive charges on an address electrode of the plasma display panel. For the purpose in the present invention, voltage pulses having different polarities and sizes are applied to a pair of sustain electrodes of a plasma display panel while sustaining a discharge for the plasma display panel.
Abstract:
An aging driving method of a field emission display device can secure long lifetimes of panel by reducing possibilities of generation of arcing, by largely increasing energy distribution under a low voltage, and by applying a pulse voltage which is varied to reduce energy distribution under a high voltage as time goes, in aging processing. In addition, aging is performed in a very short time by using small energy in a pulse supply, thereby preventing a damage of a panel and much shortening an aging time. In addition, aging is performed in each pre-aging process and a main-aging process, to reduce contaminants, thereby lengthening lifetimes of a panel and securing reliability of a product.
