FIELD EMISSION DISPLAY HAVING AN INVISIBLE SPACER THEREOF

摘要

A field emission display (100) includes a cathode assembly (102), an anode plate (104), and a spacer (108), which extends between the cathode assembly (102) and the anode plate (104). The spacer (108) is comprised of a spacer material having a dielectric constant less than 100. A discharging period neutralizes positive electrical charge (244) and renders the spacer (108) invisible to a viewer of the field emission display (100). Operating a field emission display (100) to render a spacer (108) invisible by providing a cathode assembly (102), an anode plate (104), and a spacer (108) comprised of a spacer material with a dielectric constant less than 100 and neutralizing positive electrical charge (244) on spacer (108).
