Embodiment Construction

[0014] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, the anti-oxidation composite thin film electrode of the present invention includes a substrate 1 on which a transition layer 2 , a conductive layer 3 and a protective layer 4 are sequentially arranged.

[0016] The above-mentioned substrate is an insulating material with a smooth surface, which can be an inorganic glass substrate, an organic polymer substrate, a ceramic substrate or a composite substrate composed of these materials.

[0017] The aforementioned transition layer is made of metal or compound. The metal material forming the transition layer is one of chromium, aluminum, titanium, molybdenum, nickel, copper or an alloy or mixture containing these metal materials. The material of the compound forming the transition layer is a laminated structure composed of one or more of indium oxide, zinc oxide, nickel oxi...

Abstract

The invention relates to an anti-oxidation composite membrane electrode, which comprises a substrate. The substrate is provided with a transition layer, a conducting layer and a protective layer in turn. The transition layer is made of a metal material (such as chromium, aluminum, titanium, molybdenum, niobium, tantalum, nickel and copper) or a compound material (such as indium oxide, zinc oxide, nickel oxide, vanadium oxide, silicon oxide, aluminum oxide, silicon nitride, aluminum nitride, and silicon oxynitride). The conducting layer is made of silver with high electrical conductivity, a silver-containing alloy or a mixture containing silver metal. The protective layer is made of a metal material (such as the chromium, the aluminum, the titanium, the molybdenum, the niobium, the tantalum, the nickel and the copper) or a compound material (such as zinc sulfide, the zinc oxide, tin dioxide, tungsten oxide, the indium oxide, the nickel oxide, the vanadium oxide, molybdenum oxide, titanium oxide, chromium oxide, niobium oxide and tantalum oxide). The membrane electrode can bear high-temperature thermal treatment and is not oxidized, thereby avoiding electrode oxidation in a sealing process, reducing the resistance of a flat display electrode and improving the display quality of a flat display.

Description

technical field [0001] The invention relates to an anti-oxidation composite film electrode. Background technique [0002] In recent years, flat panel display technology has developed rapidly, among which plasma flat panel display (PDP) has a very important position in the large-screen display market, and has entered public places, business applications and homes. The field emission flat panel display (FED) has a series of advantages such as self-illumination, wide viewing angle, high brightness, fast response speed, rich and bright colors, etc. It is a new type of flat panel display technology that combines the advantages of liquid crystal (LCD) and traditional CRT displays. Its module thickness is the same as that of PDP module and LCD module. It has natural high brightness and bright colors, suitable for video dynamic display, and its energy consumption is lower than that of PDP, LCD and CRT. Therefore, FED has broad application prospects. [0003] Both PDP and FED displ...
