CIRCUIT FOR STABILIZING SCREEN VOLTAGE

摘要

PURPOSE: A screen voltage stabilizing circuit is provided to improve a brightness of a screen and a performance of a screen quality by adjusting to supply a stable screen voltage constantly. CONSTITUTION: The screen voltage stabilizing circuit comprises: a horizontal output part(100) which receives a horizontal driving signal to amplify the received signal and corrects am image distortedly displayed by a condenser serially connected to a horizontal deflection coil, wherein amplified driving current generates a saw tooth wave current, a FBT which induces a voltage of a secondary by a voltage of a primary according to a winding rate; a high pressure output part (110) which outputs a grid voltage and a voltage for a brightness limitation; and a screen voltage part (120) which maintains a voltage of a third-order side induced from the secondary of the FBT according to a PWM control signal from a microcomputer and supplies the voltage to a screen.
