The present invention provides a PDP structure including a first substrate, a second substrate and a Waffle barrier rib structure located between the first and second substrate. The Waffle barrier rib structure includes three first barrier ribs having different width and a plurality of second barrier ribs perpendicular to the first barrier ribs. The second barrier ribs are located between the two first barrier ribs, and connect the wider structure of the two first barrier ribs. Therefore, discharge spaces are formed. Because of different width, the height difference of the barrier rib structure is formed after thermal process. Hence, gas can pass through the barrier ribs structure between the front and the back substrate sealed together.

Method of manufacturing barrier ribs for a plasma display panel

The present invention is to provide a method for making a shadow mask for an opposed discharge plasma display panel by etching one lateral surface of a metal slab to produce a plurality of parallel and equidistant barrier ribs along the vertical and horizontal directions on the lateral surface and a discharging cell by enclosing every four adjacent barrier ribs. A shadow hole is formed at the middle of each discharging cell and etched through the metal slab, and at least one groove interconnected to the shadow holes is produced on another lateral surface of the metal slab by utilizing a rolling process or a stamping process. The adjacent grooves are interconnected with each other, and a plurality of air guide channels is formed on another lateral side, such that a shadow mask can be made in a simple and fast manner, chemical pollutions caused by a traditional double-sided etching can be minimized, and the product yield rate and the manufacturing cost can be effectively improved and lowered.

Plasma display panel and the manufacturing method thereof

An front plate structure for a plasma display panel is described. In accordance with the present invention, a protruding space pad structure is formed on the dielectric layer or protective layer of the front plate. The space pad is used to form the height difference on the surface of the front plate, about 3 &#x3bc;m to 15 &#x3bc;m. The height difference forms gas channels between the front plate and the discharge region to improve the performance of the vacuuming and refilling gas steps.

Front plate structure for plasma display panel

A front panel for AC plasma display panel made by: using exposure and sand blast techniques to form horizontally spaced lines of induction layer above an inner side of a glass substrate, and then making X-electrodes and Y-electrodes on the glass substrate, enabling X-electrodes and Y-electrodes to be alternatively disposed and horizontally spaced between each two adjacent lines of induction layer, and then printing a protective layer over the electrodes, enabling a straight line of discharge path to be formed between each X-electrode and Y-electrode, so that the service life of the plasma display panel can be prolonged, the intensity of electric field and UV light can be greatly improved, and the value of driving voltage can be effectively reduced.
