• A novel electron gun with a superposition of the electrostatic focus region and the deflection region^<(1)> has been designed for projection TV tube. Compared to the conventional projection gun, the Deflection lens (DFL) gun has a better magnification factor, better spherical aberration coefficient and better control of the space charge effect. The DFL gun needs a unique dynamic off-axis correction lens region to compensate for the deflection defocusing. A series of computer modeling results shows that the DFL gun gives a 5^<mA> (5% gaussian) beam spot size of 0.25 mm in a 9" 90° deflection angle tube with 30kv anode voltage.
