Title:
PLASMA DISPLAY DISCHARGE TUBE AND METHOD FOR DRIVING THE SAME
Document Type and Number:
WIPO Patent Application WO/1998/012728
Kind Code:
A1
Abstract:
In a plasma display discharge tube in which an XY matrix electrode is constituted by arranging pluralities of stripe-like anodes (11) and stripe-like cathodes (9) at prescribed intervals so that they can cross each other and by using the space formed by each of intersection as a picture element, and which is made to display a picture by selectively exciting the picture elements in accordance with the picture, an AC type memory electrode (1) which is opposed to the XY matrix electrodes (9 and 11) and commonly used by all picture elements, and an AC type auxiliary electrode (5) which is brought into contact with the electrode (1) through an insulating layer and supplies electric power by utilizing the coupling capacitance formed between the electrodes (1 and 5) are provided so that memory discharge display can be made between the matrix electrodes (9 and 11) and the memory electrode (1). When the discharge tube is constituted in such a way as described above, the discharge tube can have a simplified electrode structure, can be manufactured through a reduced manufacturing process, can be driven by using the pulse memory type driving method which has been considered to be realized only in DC plasma display discharge tubes having high luminous efficacy and responsiveness, and can be provided with AC type electrodes having long service lives.
