Field emission display structure by utilizing thick film medium as separant

Abstract

The invention provides a field emission display structure using a thick film medium as a spacer and a manufacturing method thereof. The field emission display structure is composed of a cathode substrate and an anode substrate, and a thick film is arranged between the cathode substrate and the anode substrate. The membrane dielectric spacer is arranged on the glass substrate of the cathode substrate, and the spacer and the glass substrate are firmly bonded together to form a whole. The spacers are evenly spaced in the horizontal and vertical directions, and the distance between adjacent spacers in the horizontal and vertical directions is 10-50mm. The field emission display structure includes two-pole structure, three-pole structure and multi-pole structure. The invention can realize the patterning of the spacers used in the field emission display structure, avoid the complex installation process when making the spacers, solve the problem of inaccurate alignment in the placement of the spacers, and solve the original discrete spacer assembly problem. In order to solve the problem, the process difficulty is reduced, and the stability of device performance is increased.

Description

technical field [0001] The invention relates to field emission display technology, in particular to a field emission display structure using a thick film medium as a spacer and a manufacturing method thereof. Background technique [0002] Field emission display (Field emission display, FED) is the product of the combination of vacuum technology and microelectronics technology. It is composed of an anode substrate and a cathode substrate. The anode and cathode substrates are supported by spacers. The space between the two substrates It is a vacuum, and its working principle is to suppress the potential barrier on the surface of the object by a strong external electric field, so that the height of the potential barrier is reduced and the width is narrowed. When the width of the potential barrier is narrow enough to be comparable to the wavelength of electrons, electrons pass through the tunnel The effect penetrates the potential barrier and escapes into the vacuum to bombard t...
