A new mixed-mode sustain method to improve the luminous efficiency of alternating current plasma display panels

In this paper, a new mixed-mode sustain method to improve the luminous efficiency of alternating current plasma display panels is proposed. An opposite discharge is initiated between successive surface sustain discharges during the sustain period. The opposite discharge not only has a higher ultraviolet photon collection factor, but also improves the surface sustain discharge efficiency for the production of ultraviolet photons. The experimental results show that a 21/spl sim/59% improvement in luminous efficiency within a sustain voltage range of 170 V to 190 V is achieved by the new mixed-mode sustain driving approach, as compared with the conventional surface-type sustain method.
