Abstract

A deflection beam lens system for CRT includes cone shell of CRT, glass screen of CRT, glass tube neck, deflection joke and electron beam gun etc. in which the electron beam gun consists of cathode, control, screen, focus and anode electrode. It features that the anode is constituted by coating conductive paint on the proper position of inside wall between the glass tube neck and glass screen of CRT, and the middle point between the focus electrode and anode located in the deflection magnetic field region generated by deflection joke installed on the outside wall of glass tube neck, then the static field focus region of main lens formed by electron beam and the deflection magnetic field region of deflection joke occupy the same space and overlap to force the focus and deflection effect of beam happen in the same space and simultaneous event when focused by static field focus and deflected by deflection joke.
