Abstract

A field emission display (100) includes a cathode plate (104) having a plurality of electron emitters (112), ballast resistors (118), an anode plate (120) having an anode (124), and a scan mode control circuit (130). The scan mode control circuit (130) is coupled to a video control circuit (160) via a scan mode switching circuit (150). The scan mode control circuit (130) cooperates with the scan mode switching circuit (150) and the video control circuit (160) to automatically switch between a single scan mode of operation and a multi-scan mode of operation.
