Title:
HORIZONTAL DEFLECTION CIRCUIT
Document Type and Number:
Japanese Patent JP3969326
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize a correction circuit for correcting the raster amplitude changes or raster distortions resulting from the change of a high voltage current, in a relatively simple circuit configuration with less power at a low cost.
SOLUTION: A raster correction circuit 3 for correcting a raster amplitude is provided in the inside (the primary side of a flyback transformer) of a horizontal deflection circuit 1. The correction circuit 3 is provided with a pulse time detection circuit for detecting the fall time of a resonance pulse or a high-voltage driving current detection circuit for detecting a high-voltage driving current flowing into the horizontal deflection circuit.
