Abstract:
Method and apparatus for the transmission of images to a screen, wherein luminescence centers of the screen are excited by way of electron beams controlled to suit the image to be transmitted. The electrons are emitted by cathode tips of a thin-film field-effect cathode. The cathode tips are driven individually, the flow of electrons emitted from each cathode tip corresponding to the grey tone for each image point. The cathode tips may be driven by mutually intersecting conducting strips to which are fed successive trigger pulses. In another version, the cathode tips are driven by the use of charge transfer systems, which enable a still picture to be produced by concurrently driving the cathode tips in their entirety.

Abstract:
There is provided a field emission electron source at a low cost in which electrons can be emitted with a high stability and a high efficiency and a method of producing the same. In the field emission electron source, a strong electric field drift part 106 is formed on the n-type silicon substrate on the principal surface thereof and a surface electrode 107 made of a gold thin film is toned on the strong electric field drift part 106. And the ohmic electrode 2 is formed on the back surface of the n-type silicon substrate 101. In this field emission electron source 110, when the surface electrode 107 is disposed in the vacuum and a DC voltage is applied to the surface electrode 107 which is of a positive polarity with respect to the n-type silicon substrate 101 (ohmic electrode 2), electrons injected from the n-type silicon substrate 101 are drifted in the strong electric field drift part 106 and emitted through the surface electrode 107. The strong electric field drift part 106 comprises a drift. region 161 which has a cross section in the structure of mesh at right angles to the direction of thickness of the n-type silicon substrate 1, which is an electrically conductive substrate, and a heat radiation region 162 which is filled in the voids of the mesh and has a heat conduction higher than that of the drift region 161.
