It is well known that, in a color CRT, color change occurs as a result of the magnetization of the shadow mask and frame in the enviromental magnetic field. In order to clarify the influence of the mask and frame quantitatively, We analyzed the magnetization by integral equation method when a shadow mask and frame were subjected to an ambient field.
We calculated the electron beam trajectories by using the derived magnetic field distributions, and computed the miss-landing to evaluate the color change quantitatively. The results of the numerical analysis agree well with experiment, and aid in relating the shielding to the miss-landing.
