Symmetric quadrupole structure non-isolating support filed emission displayer

Abstract

The invention relates to a symmetric quadrupole structure non-isolating support filed emission displayer with a bus electrode as the symmetric center. The displayer comprises an upper substrate and a lower substrate and is characterized in that the upper substrate is provided with lengthwise anodic electrodes and a pectination dielectric layer consisting of a transverse connecting strip and a plurality of lengthwise working strips; the lengthwise center of each anodic electrode is provided with the bus electrode; the upper edge of each anodic electrode is lengthwise and alternatively providedwith a fluorophor layer and an anodic separating dielectric layer; two lengthwise sides of each lengthwise working strip are respectively provided with a grid electrode so as to form an interdigitated counter electrode structure with the bus electrode as the symmetric center; the lower substrate is provided with transverse cathodic electrodes and lengthwise auxiliary electrodes; the upper edge ofeach cathodic electrode is transversely and alternatively provided with a current-limited resistance layer and a cathodic protective dielectric layer; the intersecting part of each auxiliary electrode and each cathodic electrode is isolated by the cathodic protective dielectric layer; and an isolating dielectric layer is arranged between the upper substrate and the lower substrate. The filed emission displayer not only has novel structure and simple process, but also has uniform images and low modulating voltage and is stable and reliable in electron emission.

Description

technical field [0001] The invention relates to the technical field of field emission display manufacturing, in particular to a field emission display with a symmetrical quadrupole structure without isolation pillars, in which the anode and the grid are on the same substrate, the bus electrode is the center of symmetry, and no isolation pillars are required. Background technique [0002] Field emission display (FED) is a new type of flat panel display, which is a vacuum display controlled by a matrix addressing method with a planar field emission array cathode as the electron source and phosphor as the luminescent substance. Compared with other types of displays, the field emission display combines the high-definition image quality of the cathode ray tube display (CRT), the thinness of the liquid crystal display (LCD) and the large area of ​​the plasma display (PDP). all in one. The excellent properties of FED are: small size, light weight, low energy consumption, long serv...
