CRT display device to suppress electromagnetic radiation therefrom |
摘要 |
To construct a CRT display device capable of effectively suppressing unwanted radiation of electromagnetic waves occurring as a result of horizontal deflection or vertical deflection. A correction lead (6) series-connected to horizontal deflection coils (1) is disposed at outer peripheral positions of the horizontal deflection coils (1) and between the horizontal deflection coils (1) and a faceplate of a CRT (4). With this arrangement, electromagnetic fields produced by the horizontal deflection coils are canceled out by electromagnetic fields produced by the correction lead (6), thereby suppressing unwanted radiation of electromagnetic waves at the deflection frequency and its harmonic components.
