Problems solved by technology

When any defect occurs in the display emission area, such as improper short circuit between components, improper disconnection between components, or particles falling on the display emission area, if the corresponding signal line is cut off by laser cutting or other suitable methods , will cause the pixel structure connected by the cut off signal line to lose its luminous performance
In this way, the active area of ​​the display emission area will be greatly reduced, which will reduce the yield rate of the field emission display.

Abstract

A pixel structure of a field emission display comprises a first lead, a second lead and a plurality of electrojectors. The first lead is provided with a first main wire and a first extension portion. The first main wire has a first extension direction. The second lead is equipped with a second main wire and a second extension portion. The second main wire has a second extension direction. An overlapping area is formed between the first extension portion and the second extension portion. The electrojectors are placed betwen the first extension portion and the second extension portion, and is positioned in the overlapping area.

Description

【Technical field】 [0001] The present invention relates to a pixel structure and its repairing method, and in particular to a field emission display pixel structure and its repairing method. 【Background technique】 [0002] The luminescence principle of field emission display is to use electric field to attract electrons from the tip of the material in a vacuum environment, and the field emission electrons leaving the cathode plate are attracted by the acceleration of the positive voltage on the anode, and hit the phosphor on the anode to emit light (Luminescence) . The cathode plate is used as a field electron emission source, and the anode plate is used as a light emitting source. The electrons emitted from the cathode plate hit the fluorescent layer on the anode plate to emit light. [0003] Generally speaking, the field electron emitter of the field emission display is located in the area where two signal lines cross and overlap, and this area is also called the display e...
