Patent ID: 7091677

Claim:
An electron beam trajectory controlling device, comprising: a main deflection section having a first main coil and defining a first path and being configured to control a trajectory of an electron traveling along the first path, the main deflection section including a first auxiliary coil provided proximate the first main coil, the first auxiliary coil not being electrically coupled to the first main coil; and a minor deflection section provided adjacent to the main deflection section and having a first minor coil that is coupled to the first auxiliary coil, the minor deflection section defining a second electron path that is aligned to the first path, the minor deflection section cooperating with the main deflection section to control the trajectory of the electron, wherein the electron beam trajectory controlling device is a deflection yoke assembly or a cathode ray tube, and the first minor coil is not coupled to the first main coil, the first auxiliary coil cooperating with the first minor coil to suppress a crosstalk voltage in the minor deflection section, wherein the first auxiliary coil is wound around the main deflection section using a saddle-winding method.
