Abstract
The inventive plasma display is capable of enhancing the luminous efficiency and the brightness by minimizing ineffective ultraviolet rays. The plasma display according to the present invention comprises: a first transparent electrode having two or more protrusion parts; and a second transparent electrode having two or more protrusion parts corresponding respectively to the protrusion parts of the first transparent electrode. When discharges between the first and second transparent electrodes take place, there are two or more peaks in the discharge intensity of each transparent electrode.
Claims15
A plasma display, comprising:
- a first transparent electrode having at least two protrusion parts;
- and
- a second transparent electrode having at least two protrusion parts corresponding respectively to the protrusion parts of the first transparent electrode,
- wherein each transparent electrode comprises:
- a base part elongated in one direction;
- a neck part attached vertically to the base part and extending in a first direction, the neck part having the respective protrusion parts extending therefrom;
- a black layer formed on the base part;
- and
- a bus electrode formed on the black layer, wherein each of the protrusion parts of the first and second transparent electrodes comprises:
- a first protrusion part horizontally extended from both sides of the neck part along a first axis in a second direction that traverses the first direction, the first protrusion part being spaced with a designated gap from the base part;
- and
- a second protrusion part extended from both sides of the neck part along a second axis in the second direction and the second protrusion part being spaced with a designated gap from the first protrusion part, wherein a width of the second protrusion part of the first transparent electrode in the first direction is wider than a width of the first protrusion part of the first transparent electrode in the first direction.
A plasma display having a pair of transparent electrodes in a discharge cell, wherein each transparent electrode comprises:
- a base part elongated in one direction;
- a neck part attached vertically to the base part and extending in a first direction;
- a first protrusion part attached to the neck part so as to be located near a border area of the discharge cell, the first protrusion part extending along a second direction;
- and
- a second protrusion part attached to the neck part so as to be located near a central area of the discharge cell, the second protrusion part extending along the second direction,
- wherein a width of the second protrusion part of the one of the transparent electrodes in the first direction is wider than a width of the first protrusion part of the one of the transparent electrodes in the first direction.
A plasma display having a pair of transparent electrodes in a discharge cell, wherein each transparent electrode comprises:
- a base part elongated in one direction;
- a neck part attached to the base part at a right angle and extending along a first direction;
- a first protrusion part attached to the neck part so as to be located near a border area of the discharge cell, the first protrusion part extending along a second direction that transverses the first direction;
- and
- a second protrusion part attached to the neck part so as to be located near a central area of the discharge cell, the second protrusion part extending along the second direction,
- wherein a width of the second protrusion part of the one of the transparent electrodes in the first direction is wider than a width of the first protrusion part of the one of the transparent electrodes in the first direction.
