Abstract
A dynamic focusing circuit capable of eliminating the phase deviations between the horizontal deflection current and the horizontal frequency components by use of a pseudo horizontal output circuit which generates a horizontal component signal having low voltage and small current, and greatly enhancing the correctness of the focus, despite disturbances due to the characteristics of the CRT and deflection yoke, by use of a plurality of variable resistors which can control the amplitude of the vertical and horizontal components, the DC level of the focus signal, and the phase deviation between the horizontal deflection current and the horizontal component of the focus signal. This invention is adaptable to all monitors which has have a focus control function.
