Abstract (en)
[origin: WO2019149482A1] The invention relates to an emission device comprising - an emitter (1) which comprises a structured main emission surface (11) and which can be switched to a main potential (U1), and - a connectable field effect electron emitter (2) which comprises a structured heat emission surface (21) and which can be switched to a heat potential (U2) that differs from the main potential (U1), wherein - the heat emission surface (21) comprises a specifiable number of individually controllable field effect emitter segments (22). Such an emission device has a longer service life while maintaining a constant image quality.
