APPARATUS FOR COMPENSATING TILT OF A SCREEN IMAGE CAPABLE OF PROVIDING A CLEAR SCREEN

摘要

PURPOSE: An apparatus for compensating tilt of a screen image is provided to detect a slant according to an area and a direction through a gauss meta using an integrated circuit such as a hall element and then to automatically compensate the tilt of the screen image, thereby capable of providing a clear screen. CONSTITUTION: An amplifying member(102) amplifies the hall voltage induced from a hall element and outputs a sensing voltage. A control member(104) compares the sensing voltage from the amplifying member with the voltage of reference earth magnetism and outputs a compensating voltage of the earth magnetism according to the difference. A tilt compensating member(106) outputs a screen tilt compensating signal according to the compensating voltage of the earth magnetism to a coil(108) in order to compensate the tilt of the screen.
