What is the difference between Landing and Uniformity?
These are two different anomalies often confused. Landing is the physical position of the electron beam with reference to the correct phosphor. If the beam doesn’t land exactly center to the phosphor strip, then the screen will exhibit colored patches or shaded areas. It can also change the geometry so that lines are not straight. The reason that this may happen is due to terrestrial magnetism. This is the same phenomenon that moves a compass needle.
