Title: Tilt compensator of picture tube
Inventor: KIN GINSHIYOU
IPC: H01J29/76
Filed: 1995-12-04
Abstract: PROBLEM TO BE SOLVED: To correct tilt with an element operation through the use of a degaussing coil by comparing voltage which is fed back from the degaussing coil with a tilt correction control signal and executing a switching operation. SOLUTION: AC current for driving image receiving tube is applied to a power circuit 22 thorough a filer circuit 20 and is applied to the degaussing coil D-Coil. A tilt adjusting circuit 26 compares the voltage of a prescribed level, which is fed back from D-Coil, with a tilt correction control signal and outputs differential current. A switching circuit 24 executes the selective switching operation in accordance with the potential state of a degaussing control signal and executes the tilt correction operation by containing the element operation by a loop containing the circuit 20 and D-Coil or the tilt correction operation containing the circuit 26 and D-Coil. Thus, tilt correction can easily be executed with D-Coil without separately providing the coil for the tilt correction of the image receiving tube.
