APPARATUS AND A METHOD FOR CORRECTING A HORIZONTAL SIZE OF A MONITOR TO ALLOW A USER TO DIRECTLY CORRECT THE HORIZONTAL SIZE ACCORDING TO A TIME

摘要

PURPOSE: An apparatus and a method for correcting a horizontal size of a monitor are provided to allow a user to directly correct the change of an irregular horizontal size per product by directly inputting a correction value of the horizontal size and controlling the horizontal size. CONSTITUTION: A microcomputer(110) controls horizontal and vertical sizes of a monitor according to the change of a time, and stores and controls a horizontal size correction value inputted through an OSD(On Screen Display) menu by a user. A storing unit(120) stores the horizontal size correction value and a time inputted by the user. A deflection IC(140) adjusts horizontal and vertical output values according to a signal of the microcomputer. A horizontal size control unit(130) controls a horizontal size correction value according to a time inputted by the user. A horizontal driving unit(150) horizontal size control signals transmitted from the deflection IC and the horizontal size control unit. A horizontal deflection unit(160) provides a horizontal deflection current to a deflection yoke according to a control signal of the horizontal driving unit.
