Electron gun assembly for cathode ray tube with a voltage stabilizing suppressor ring

摘要

The electron gun assembly for cathode ray tube, has the structure in which the first, second and third grids are arranged in the traveling direction of an electron beam emitted from cathodes, and so is the fourth grid to which a anode voltage is applied, a suppressing ring is provided to be adjacent to the second and third grids, a dynamic focus voltage which is varied in synchronism with the deflection of the electron beam is applied to the first and third grids, and the first and second grids are connected to each other by means of the resistor provided adjacent thereto.
