ABSTRACT:
Display unit by cathodoluminescence excited by field emission.
It comprises a plurality of elimentary patterns, each having a cathodoluminescent anode and a cathode able to emit electrons. Each cathode comprises a plurality of electrically interconnected micropoints subject to electron emission by field effect when the cathode is negatively polarized compared with the corresponding anode, the electrons striking the latter, which is then subject to a light emission. Each anode is integrated to the corresponding cathode.
Application to the display of stationary or moving pictures.
