Problems solved by technology

Generally speaking, thermal emission is a very stable process, but the field emission process is not very stable. The electron flow in the transport layer is affected by many factors. There are large differences between each emission unit, and the fluctuation of emission is relatively large. Large, will affect the uniformity and stability of emission

Abstract

This invention discloses a resistance field emission electron negative electrode part, which is characterized by that the electron negative electrode part is located with row electrode or line electrode and it sets resistance between the row and down electrode or line or down electrode. The feedback action of the resistance can stabilize the emission and when row electrode is loaded with negative voltage and the line electrode is loaded with positive voltage, the electron injects form down electrode to the transmission layer and is accelerated and achieves the upper electrode and the part of electrons passes the upper electrode and are emitted to the vacuum.

Description

Technical field: [0001] The invention belongs to the technical field of vacuum electron emission type flat panel display devices, and in particular relates to a cathode component of field emission electrons with resistance for normal temperature electron emission. Background technique: [0002] At present, the cathode of field-assisted thermal electron emission flat panel display devices includes two basic structures of metal-insulator-metal (MIM) and metal-insulator-semiconductor-metal (MISM), wherein the former works in DC and the latter works in AC. The advantage of AC work is that the emission is uniform and stable, but the emission current is small, which often cannot meet the requirements of high-brightness display; the characteristic of DC work is that the emission current is large, but the uniformity and stability of emission are relatively poor, and often cannot reach high brightness. performance display requirements. Metal-insulator-metal (MIM) cathode work involv...
