Inert gas provided at a suitable level inside a hermetically sealed cathode-ray tube display, typically of the flat-panel type, enables the display's electron-emitting device () to be automatically cleaned during display operation subsequent to final display sealing. Upon being struck by electrons emitted by the electron-emitting device, atoms () of the inert gas ionize to produce positively charged ions () which travel backward to the electron-emitting device and dislodge overlying contaminant material (and). A getter () collects dislodged contaminant. A reservoir () provides inert gas to replace inert gas lost during the cleaning process.
