Abstract

The invention belongs to the technical field of display, and discloses a field emission display pixel unit, which comprises a gate electrode, an electron collection electrode, an emission tip, a driving circuit and a constant current source circuit, the gate electrode is an annular electrode, the gate electrode is connected with the driving circuit, and the electronic collecting electrode is connected with the constant current source circuit, wherein the emission tip is arranged below the inner ring of the gate electrode, and the electron collection electrode is located above the gate electrode. The field emission display pixel unit provided by the invention can realize uniformity of pixel brightness.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a field emission display pixel unit. Background technique [0002] Due to the uniformity defect of field emission, the field emission display unit will have the problem of uneven brightness when it is used on a large scale, so there are problems in large-screen application and lifespan. Among them, the inconsistency of the field emission efficiency is mainly due to the inconsistency of the distance between the gate electrode and the electron emission tip caused by the process, which is finally manifested as the inconsistency of the pixel brightness. Contents of the invention [0003] The invention provides a field emission display pixel unit, which solves the technical problem of uneven brightness of the pixel unit in the prior art. [0004] In order to solve the above technical problems, the present invention provides a field emission display pixel unit, comprising: a gate e...
