Title:
CRT DISPLAY
Document Type and Number:
Japanese Patent JP2000115566
Kind Code:
A
Abstract:
To effectively suppress the undesired radiation of electromagnetic waves generated accompanying horizontal deflection and vertical deflection.
A correcting lead 6 to be connected serially to a horizontal deflection coil 1 is arranged at the outer peripheral position of the coil 1 and between the coil 1 and the displaying surface of CRT 4. Thus, an electromagnetic field generated from the coil 1 is cancelled by an electromagnetic field by the lead 6 to suppress the undesired radiation of the electromagnetic waves of a deflection frequency and its higher harmonic components.
