Abstract
PURPOSE: To improve raster strain by using an electron gun in which at least a set of deflection electrodes are formed into almost board shape and arranged in a mutually facing manner by turning its bottom and upper sides toward the axial direction of electron beam.
CONSTITUTION: Electron beam emitted from cathode reaches the Y-axle deflection electrode 7 and deflected there by polarity applied to the electrode 7 and its level, and then enters the through hole 9a of the X-Y shield electrode 9 at a', b', and C'. Then, it undergoes deflection toward X-axle direction by the X-axle deflection electrode 8. In the electrode plate 8c, there is a different electron beam-passing distance between the bottom 8a side and the upper 8b side because of its almost board shape, so that the degree of deflection is different. Bam put in the electrode 8 at the point a' undergoes a greater deflection, and beam from the point b' undergoes a smaller deflection, and the beam from the point c' undergoes a medium deflection. By using such an electron gun 3' in a flat type cathode ray tube, strain- free laster can be drawn.
