发明名称 ELECTRON GUN FOR C-CRT
摘要 An electron gun for color image-receiving tube is disclosed in which a large opening for reducing the effect of spherical aberration is formed, an anode electrode and focus electrode are formed which are for reducing the effect of astigmatism, an opening consisting of a circular arc and straight line is formed on the middle of an inner electrode plate located in the anode electrode and an opening consisting of one straight line and circular arc is formed on both sides of the electrode, a rectangular opening whose vertical length is longer than its horizontal length is formed on the middle of an inner electrode plate of the focus electrode and semi-rectangular opening is formed on its both sides, thereby improving the resolution of the color image-receiving tube.
