Dynamic studies on the charging of spacers for high‐voltage field‐emission displays

Abstract

Abstract— In this article, a systematic study on the relationship between the rate of spacer surface‐charge accumulation and the anode voltages in a dynamic setting is presented. The spacers are placed in a test package simulating a field‐emission panel where electron trajectories are recorded along a preset timeline. True secondary emission of spacers under the influence of an anode field is then deduced and the factors affecting the rate of charge accumulation on the spacer surface are discussed. The results of invisible spacers under different operating conditions of anode voltage, emission current, and pulse width will also be given.
