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.

Embodiment Construction

[0018] In a triode structure, the emitting material must be accurately filled into the pores of the dielectric membrane. If the emitter material is misplaced or if the emitter layer is too thick, a short circuit between the cathode and the grid will result. If the area of ​​the emitting material is much smaller than the pore size of the dielectric film, although the short circuit between the cathode and the grid is avoided, the driving voltage will increase rapidly.

[0019] The patterned field emitter layer can usually be printed by screen printing. In order to avoid the influence of subsequent processes such as dielectric layer preparation and gate preparation on the emitter, a protective layer must be covered on the emitter. This increases process complexity and still some emitter performance will be compromised. If the dielectric film holes and grid electrodes are prepared first, it is difficult to accurately fill the emission material into the film holes by screen print...

Description

technical field [0001] The invention relates to a method for manufacturing a field emission display device, and relates to the technical field of field emission display devices, growth of nanometer materials and surface treatment. 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 brightness; Therefore, there is a contradicti...
