Abstract

The invention provides a field emission display structure by utilizing a thick film medium as a separant, and a manufacturing method of the field emission display structure. The field emission display structure consists of a cathode substrate and an anode substrate, thick film medium separants are arranged between the cathode substrate and the anode substrate, and are arranged on a glass base of the cathode substrate and are firmly adhered with the glass base into a whole body. The separants are arranged on the horizontal direction and the vertical direction at intervals uniformly, and the distance between every two adjacent separants on the horizontal direction and the vertical direction is 10-50mm. The field emission display structure has a bipolar structure, a tripolar structure and a multi-pole structure. According to the field emission display structure, the separants used by the field emission display structure can be graphical, the complicated mounting process when the separants are manufactured is avoided, the problem of inaccurate alignment caused by the arrangement of the separants can be solved, also the problem of the assembly of the original separated separants is solved, the process difficulty is lowered, and the stability of the performance of devices is improved.

Description

Technical field [0001] The present invention involves the launching technology of the field, and especially involves a field transmission display structure and its production method with thick membrane medium as a isolation. Background technique [0002] Field Emission Display (FED) is a product of combining vacuum technology and microelectronics technology. It is composed of anode substrates and cathode substrates.For vacuum, its working principle is to rely on a strong external electric field to suppress the surface barrier on the surface of the object, reduce the height of the potential, and narrow the width. When the width of the potential barrier is narrowed to the wavelength that can be compared with the wavelength of the electrons, the electrons pass through the tunnel through the tunnel.Effects through the piercing barriers into vacuum and bombard the analmed fluorescent powder.Because its working principle is similar to the commonly used CRT display, it is called a flat ...
