Description

technical field [0001] The invention relates to a unit structure of a field emission display device, and relates to the structural design and preparation method of field emission materials, data electrodes, scanning electrodes and anodes of the field emission display device. Background technique [0002] At present, field emission display device (FED), as a new type of flat panel display device, still has a certain distance from marketization, and there are some key technical bottlenecks. Among them, the design and preparation of the triode structure is an important factor affecting the practical application of field emission display devices. [0003] The simplest field emission display can be formed by adopting a diode structure, and the display of video images can be realized through matrix scanning. In a field emission display with a two-pole structure, on the one hand, the anode needs high voltage to give electrons enough energy to bombard the phosphor to achieve high b...

AI Technical Summary

Problems solved by technology

Although the protective layer has a certain protective effect on the cathode, it will still cause damage to some emitters and affect the performance of the display device.

If the CVD method is used in the triode structure to directly grow the emitting material in the dielectric film hole, although the difficulty of material filling can be avoided, the glass substrate is easily damaged due to the high working temperature of CVD.
