ABSTRACT:
A flat thermionic emission screen (1) has a first substrate (2) on which are arranged an emission cathode (4) and an electron extraction grid (8), a second substrate (12) facing the first substrate (2) on which is arranged an anode (14) designed to collect the electrons emitted by the cathode (4), and an electronic control circuit of the anode (14) voltage having at least one commutation component (18, 20). The commutation component (18,20) is built into the first substrate (2) and in the second substrate (12) of the screen (1).
