Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] As shown in FIG. 2 : the material of the cathode substrate 7 can be glass, ceramic, metal or silicon wafer. First, for glass or ceramic substrates, conductive metal electrodes or transparent conductive electrodes (such as indium tin oxide, ITO for short) can be prepared on them as cathode electrode strips 8 , and cathodes 9 are prepared on cathode electrode strips 8 . The cathode 9 can be a microtip array cold cathode, a thin film cold cathode, a carbon nanotube cold cathode, a metal or semiconductor nanomaterial cold cathode such as nanowires, nanoribbons, nanorods, and the like. Secondly, for metal or silicon wafer substrates, since they are conductive, cathodes 9 can be fabricated directly on them. The cathode 9 can be a microtip array cold cathode, a thin film cold cathode, a carbon nanotube cold cathode, a metal or semiconductor nanomaterial cold...

Abstract

The invention provides a field emission display with simple process, excellent property and multilayer structure, comprising cathode substrate, grid substrate and anode substrate, mutually insulated by solid insulating materials and provided with working voltages, respectively, and the three substrates are fixed at preset intervals and vacuum-packaged, where the said cathode substrate is provided with cathodes as electron emission sources, the said grid substrate is made with grid holes limiting electron channels and a grid electrode is arranged in the position corresponding to a grid hole, and the said anode substrate is coated with conductive layer and phosphor powder. The invention simplifies the process complexity and reduces the processing cost; besides, on the basis of multilayer structure, can conveniently make focusing pole, effectively focusing electron beams emitted by cathode electron emission sources and thus eliminating the interference between pixels.

Description

technical field [0001] The present invention relates to displays, and more particularly, to a field emission display with a multi-layer structure. Background technique [0002] Flat panel displays are widely used due to their thinness and lightness. Common flat panel displays include liquid crystal displays (LCDs), plasma displays (PDPs), electroluminescence (EL) displays, flat matrix (CRT) displays, and field emission displays (FEDs). Among them, the liquid crystal display has a clear display effect and low power consumption, so it occupies the market of notebook computers and some desktop computer monitors. However, due to its high cost and response time problem, it is difficult to achieve large-screen high-speed display. However, the commonly used products such as plasma display and flat matrix display have high power consumption and large heat loss, and they still have shortcomings that cannot be overcome. [0003] Field emission displays (FEDs) use cold cathode arrays...
