Title: Horizontal deflection circuit
Inventor: TAKAHASHI KIYOSHI
IPC: G09G1/16
Filed: 1994-12-14
Abstract: PURPOSE: To prevent a horizontal output element from breaking by suppressing variation of the output signal of an AFC in a transition period wherein an input horizontal synchronizing signal is switched and normally varying its horizontal oscillation frequency. CONSTITUTION: In transition periods of output voltages V1 and V2 from comparators COMP1 and COMP2, the output voltage V2 varies earlier with the time constant of a filter circuit and the voltage V1 varies later. Output voltages V3 and V4 from the comparators COMP1 and COMP2 are both at H level in stationary operation and in transition periods, the voltage at the inverted input terminal of the comparator COMP1 becomes higher than the voltage at the uninverted input terminal, so that the output voltage V3 goes down to L level in the period. Further, the voltage at the uninverted input terminal of the comparator COMP2 is higher than the voltage at the inverted input terminal and the output voltage V4 is still at the H level.  When one of the output voltages V3 and V4 falls to the L level, the anode-side output voltage V5 of diodes D1 and D2 is determined by it and in this transition period, a switch SW is opened to stop supplying a signal to an AFC circuit 3.
