IPC: H01J29/50
Filed: 1983-05-25
Abstract: PURPOSE:To improve resolution while reducing the diameter of a beam spot by making a position of an electrode piece for correcting an electric field to satisfy specific relation in the proper range to remove astigmatism completely. CONSTITUTION:Presuming that the widths of the electrodes for correcting an electric field of G3, G4 electrodes 11, 12 are W3, W4 and the distances from the opening parts are g3, g4, expansion of g3 and reduction of W3 weaken an effect of the electric field coorection electrodes in G3 electrode so that the equipotential line deeply intrudes in the horizontal direction so as to weaken the horizontal focusing force. On the other hand, the equipotential line deeply intrudes horizontally due to the expansion of g4 and the reduction of W4 so as to weaken the horizontal emission force. These four kinds of parameter are specified for balancing the vertical-and-horizontal focusing forces in order to remove astigmatism. Accordingly, the range of g4 is so set up as to satisfy the relation of the formula I . Thereby, a good spot property can be obtained so as to remarkably improved resolution of a picture tube.
