CIRCUIT FOR STABILIZING HIGH TENSION OF CRT, METHOD THEREOF AND VIDEO DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a circuit for stabilizing a high tension of a CRT capable of overcoming inaccuracy of image size correction and partial correction due to a delay and of reducing the production cost. SOLUTION: The circuit for stabilizing a high tension of a CRT includes; a feedback unit that receives a cutoff voltage from the CRT; a storing unit that stores high tension compensation data according to the variation quantity of the cutoff voltage; and a compensating unit that compares the variation quantity of the cutoff voltage with the high tension compensation data to correct the high tension.
