Abstract

The field emission addressing structure with low modulation voltage dynamic range relates to field emission display devices, especially the structure for realizing low modulation voltage dynamic range by changing the structure of field emission devices. The structure consists of an upper medium plate (13) and a lower medium plate (12) stacked together, the upper medium plate is provided with an upper medium tapered hole (17), and the lower medium plate is provided with a lower medium tapered hole (16), on the upper surface of the upper dielectric plate, that is, the aperture end of the upper medium tapered hole is provided with a modulation electrode (15), and on the upper surface of the lower dielectric plate, that is, the aperture end of the lower medium tapered hole is provided with an addressing electrode (14), wherein the centerlines of the upper medium tapered hole on the upper medium plate and the lower medium tapered hole on the lower medium plate are not on the same center line, the invention provides a low field emission display screen modulation voltage seeker The field emission addressing structure with low modulation voltage dynamic range achieves the purpose of low modulation voltage addressing by controlling the migration of secondary electrons on the surface of the medium.

Description

technical field [0001] The invention relates to a field emission display device, especially a structure for realizing a low modulation voltage dynamic range by changing the structure of the field emission device. Background technique [0002] At present, it is a hot spot in the development of flat panel displays. At present, there are more researches on flat panel displays, such as liquid crystal display, plasma display, field emission display, etc., because liquid crystal display is passive light emitting, so the brightness is low, and at the same time, it has small viewing angle and slow response speed. Plasma display has large size display, but it has certain difficulties in luminous efficiency and high resolution display; field emission display is a cold cathode emission, active light-emitting flat panel display device, with high luminous brightness and low power consumption , large viewing angle, suitable for high-resolution display, etc., so the research on field emiss...
