Abstract: A structure to reduce the likelihood of flashover in a parallel plate electron beam array is disclosed. The structure may comprise a means for generating a low intensity electric field in the vicinity of a spacer separating the parallel plates of the array, and the anode. The presence of the electric field in the vicinity of the spacer is not conducive to the occurrence of a surface supported flashover on the gates and emitters. The electric field means may be provided by a conductive coating on one or more surfaces of the spacer. Alternatively, the electric field means may be provided by a conductive coating on a guard ring located within the array in the vicinity of the spacer. Methods of making the structure are also disclosed.

Abstract: The present invention provides an electron gun assembly including at least one field emission type cold cathode acting as an electron beam source, a support for supporting the cold cathode thereon, a control electrode spaced away from the cold cathode, the control electrode cooperating with the support to enclose the cold cathode therein, a thermal shield member provided both around the control electrode and below the support to prevent heat conduction to the cold cathode. The thermal shield member does not allow heat conduction to the cold cathode when the electron gun assembly is to be enclosed in a glass valve by softening a neck portion of the glass valve with an oxygen burner and then attaching the softened neck portion to the electron gun assembly, resulting in that an emitter of the cold cathode is not increased in temperature and that a summit of an emitter is not oxidized. Thus, the work function of the cold cathode is not increased, and thereby there can be obtained a cathode ray tube including a field emission type cold cathode in which the emission performance is not degraded.
