Problems solved by technology

At present, the supporting technology of small-sized field emission display devices is mainly realized by microelectronics technology, complex bonding technology, and adhesion technology. , large-scale field emission display devices
However, wires, sheets, columns or microbeads made of cheap glass, ceramics and other materials are not easy to solve problems such as aspect ratio, uniformity and charge accumulation because of their small size, and they are still not easy to promote.
Motorola company provides a kind of patent of invention that the publication number is CN1309813A, discloses a kind of field emission display with adhesion spacer and adhesion technology, and this invention has solved the installation problem of support object of smaller size, but technology is still comparatively small. Complicated, unresolved issue of charge accumulation

Embodiment Construction

[0014] Such as figure 1 As shown, a better support is needed between the anode substrate 8 and the cathode substrate 1 of the field emission display device. The best embodiment of the present invention is a support formed by multiple functional material layers, namely the insulating layer 6, the black matrix material layer 5, the getter material layer 4 and the insulating layer 3 overlapped in sequence, first in the anode strip 7 gaps A layer of insulating layer 6 is formed by coating, printing, coating or template method, which can be aluminum oxide, silicon dioxide, tantalum pentoxide, etc., so as to avoid short circuit or leakage between the black matrix material layer 5 and the anode strip. Then, print or coat a layer of black matrix material layer 5 on it, which can be graphite milk, etc., to eliminate the glare of the screen and improve the display contrast of the screen. The third layer of material layer is a non-evaporable getter material Layer 4, can be zirconium, va...

Abstract

An upholder composed of lapped multiple functional material layer is formed between the anode base plate and the cathode base plate. The lapped layers include the two layers of insulation layers as well as black surround material layer and the suction air layer between the said insulation layer. Using the printing, filming, coating, or molding methods laps each material layer, forming the upholder on the anode base plate. The invented upholder features simple technique, applicable to the assembly in middle and large sizes and full utilization of the gaps of the anode straps, providing the functions of support, suction air, black surround and discharging electricity.

Description

technical field [0001] The invention belongs to the technical field of manufacturing flat panel display devices, in particular to a support for field emission flat panel display devices. Background technique [0002] There are more and more types of flat panel display devices, such as field emission display device (FED), vacuum fluorescent display device (VFD), flat cathode ray tube (ThinCRT), field ion display device (FID), liquid crystal display device (LCD) , Plasma Display Device (PDP), etc. In the above-mentioned flat panel display devices, some need to use supports to separate the two substrates in the display device, so as to determine the relative position of the two substrates and ensure that the distance between the two substrates is equal; some need to use supports to support The substrate is subjected to atmospheric pressure. [0003] Field emission display devices usually have a cathode substrate and an anode substrate facing each other. A certain distance mus...
