    Abstract: A field emission device (100) is provided for reducing power and audible noise during discharging of dielectric surfaces (137, 138). The field emission device (100) comprises an anode (122) and a first substrate (111) including a cathode plate (110) comprising a plurality of active display devices (114) and dielectric surfaces (137, 138). The plurality of active display devices (114) emit electrons (132) to strike the anode during a scanning mode, and emit electrons (135) to strike the dielectric surfaces (137, 138) during a discharge mode. At least one of a plurality of spacers (136) positioned between the anode (122) and the cathode plate (110) comprise a first sense electrode (142) positioned proximate to the anode (122), and a second sense electrode (144) positioned proximate to the cathode plate (110) and spaced apart from the first sense electrode (142). A circuit (222, 224, 226) for sensing a difference in charge between the first and second sense electrodes (142, 144) is coupled to the anode (122) and cathode plate (110) for alternately initiating the scanning mode and the discharge mode in response to the difference in charge reaching a threshold.
