Problems solved by technology

[0011] In the above-mentioned front panel manufacturing method, since the electrodes and the black matrix are manufactured by separate methods, the number of processing steps is increased, and the possibility of failure is also increased, thereby reducing production efficiency
Especially in the case where the front plate electrode is only made of metal, there is a problem that the external light can be reflected due to the low absorption rate of the external light, and the black matrix cannot be made into a fine pattern

Embodiment 1

[0050] 160g of a mixture of 25% by weight of SiO and 75% by weight of Fe was put into the deposition boat, the particle size of SiO was 1.5 mm, and the distance between the deposition boat and the plate was adjusted to be 18.5 cm.

[0051] Put the plate into the vacuum chamber and keep the vacuum at 2×10 -3 Pa. While varying the temperature of the deposition boat, a 400 nm thick black coating was deposited on the plate.

[0052] After forming a black coating on the panel, an organic positive photoresist is deposited on the coating by centrifugation and exposed through a shadow mask using ultraviolet (UV) light. The resulting member is developed to remove the unexposed areas of the photoresist layer to form a photoresist pattern. Using these photoresist patterns, the black overlay was patterned. After cleaning with ion-free water, the photoresist pattern was stripped to obtain the second and third electrodes and the black matrix pattern, or to obtain the second and third ele...

Embodiment 2

[0054] The same method as in Example 1 was used to manufacture the black matrix pattern, except that the particle size of SiO was 1 mm, and 200 mg of a mixture of SiO and iron (Fe) was put into the deposition boat.

Embodiment 3

[0056] Using the same method as in Example 1, the black matrix pattern was manufactured, except that a mixture of 40% by weight of SiO and 60% by weight of 220mg of SiO and 60% by weight of titanium (Ti) was put into the deposition boat, and the particle size of SiO was 1mm.

Abstract

The present invention provides a panel for a plasma display panel (PDP), a method of manufacturing the panel, and a PDP using the panel. Such a board includes: a board made of a transparent material; a plurality of electrode pairs formed in a predetermined pattern on the board; and a dielectric layer covering the electrodes made on the board, wherein the electrodes are made of a first A dielectric component and at least one selected from iron (Fe), cobalt (Co), vanadium (V), titanium (Ti), aluminum (Al), silver (Ag), silicon (Si), germanium (Ge), made of the second component of yttrium (Y), zinc (Zn), zirconium (Zr), tungsten (W), tantalum (Ta), copper (Cu), and platinum (Pt), where the first The amounts of the electrical component and the second component vary gradually in the direction of the thickness of the electrode.

Description

technical field [0001] The present invention relates to a plasma display panel (PDP), and more particularly, to a panel of a PDP on which a discharge electrode is fabricated, a method of manufacturing the panel, and a PDP using the panel. Background technique [0002] A plasma display uses ultraviolet (UV) light generated by a plasma discharge between two substrates sealed with a plasma gas to excite a predetermined phosphor pattern to produce a desired visible image. [0003] Such plasma displays are generally classified into DC type and AC type according to the corresponding excitation voltage, that is, the discharge mechanism. The AC-type PDP is divided into two types: one is the double-substrate double-electrode type, and the other is the surface discharge type. [0004] In the DC type PDP, the electrodes are exposed to the discharge space, and charges are directly transferred between the opposite electrodes. AC-type PDP uses a dielectric layer to cover the electrodes....
