Abstract
A plasma display panel comprises a face plate, a rear plate, a plurality of anodes, cathodes, auxiliary anodes, first barrier ribs, second barrier ribs and discharge spaces. Each auxiliary anode is interposed between each first barrier rib and each second barrier rib. The PDP is easy to manufacture due to the absence of an applied dielectric layer. The circuit for driving the plasma display panel is simplified by using a DC auxiliary discharge. The width of the cathode is not limited by the auxiliary anode, but maximized because of the auxiliary anodes placement within the discharge space, so that the higher brightness is realized by the enhanced discharge.
Claims4
A DC triggered plasma display panel comprising:
- a face plate and a rear plate spaced apart from said face plate by a first predetermined distance;
- a plurality of parallel anodes spaced at a predetermined interval on an inner surface of said face plate;
- a plurality of cathodes arranged perpendicular to said anodes and parallel to one another on an inner surface of said rear plate;
- a plurality of first barrier ribs arranged parallel to and between said anodes on said face plate;
- a plurality of second barrier ribs formed on said rear plate aligned with said first barrier ribs and arranged perpendicular to said cathodes, thereby forming a plurality of discharge spaces between said face place and rear plate;
- a plurality of auxiliary anodes sandwiched between said first and second barrier ribs, with at least one edge of said auxiliary nodes being exposed to the inner space between said face plate and rear plate, thereby causing an auxiliary discharge to develop between at least one of the auxiliary anodes and at lest one of the cathodes in response to a trigger voltage;
- and
- voltage triggering means coupled to said plurality of auxiliary anodes and said plurality of cathodes for selectively generating the trigger voltage across said at least one auxiliary anode and said at least one cathode,
- wherein each of said first barriers rib and a corresponding one of said second barrier ribs are in partial contact with each other, the only one edge of each of said auxiliary anodes is exposed to said discharge space.
