TRANSPOSED BI-DIRECTIONAL SCANNING IN A CATHODE RAY TUBE

摘要

A video display includes a transposed scanning system. The transposed scanning system utilizes sinusoidal scanning to provide bi-directional scanning along a short axis of a display screen (31) of a cathode ray tube (30). Therefore, the more difficult to achieve, higher frequency scan task is assigned to the short axis requiring the least deflection energy.
