Trapezium distortion does not follow the use of asymmetric drive to the deflector plates nearer the cathode, but other faults may, such as a variation in the goodness of the focus in different parts of the screen.

Trapezium distortion does not follow the use of asymmetric drive to the deflector plates nearer the cathode, but other faults may, such as a variation in the goodness of the focus in different parts of the screen. Briefly, the mechanism of trapezium distortion is that the unbalanced drive to the deflector plates causes the mean potential to differ from that of the final anode, setting up an additional weak electrostatic lens. The beam undergoes deflection as it passes the first pair of plates, and is then subjected to refraction in the same plane according to the power of the lens formed by the second pair.
