Abstract

A horizontal deflection circuit having a horizontal output transistor that receives an input horizontal driving signal and drives a horizontal deflection coil includes a current controlling unit to selectively perform an operation to decrease a base current applied to a base terminal of the horizontal output transistor, and a controlling unit to sense a frequency of the horizontal driving signal and to enable the operation of the current controlling unit when the sensed frequency of the horizontal driving signal is higher than a predetermined level. Accordingly, the horizontal deflection circuit can control the base current of the horizontal output transistor according to a frequency mode, thereby decreasing damage to the horizontal output transistor.

Description

technical field [0001] The present general inventive concept relates to a horizontal deflection circuit, and more particularly, to a horizontal deflection circuit capable of controlling a base current of a horizontal output transistor in a frequency mode, thereby reducing damage to the horizontal output transistor. Background technique [0002] Generally, a cathode ray tube (CRT) used in an image display device utilizes the principle that corresponding electron beams having different numbers collide with red, green, and blue (RGB ) of monochromatic or fluorescent materials, whereby light of varying brightness or color is produced. [0003] The CRT image display device receives image signals and synchronization signals input from a video card of a computer system, and displays information on a screen. The CRT image display device includes: a video system for processing image signals; a deflection system for vertical or horizontal deflection; and a power supply system. [00...
