Abstract: A dynamic focus circuit used in a display device having a cathode ray tube and adapted for controlling convergence of an electron beam of the cathode ray tube. In the dynamic focus circuit, a horizontal deflection circuit generates a saw-tooth-wave current and a flyback transformer generates a high voltage for accelerating an electron beam. An orthogonal transformer receives a signal corresponding to the saw-tooth-wave current through a primary winding via the flyback transformer while receiving a control signal of a control circuit through a control winding and generates a dynamic focus voltage through a secondary winding. A capacitor supplies the dynamic focus voltage to a cathode ray tube. Thus, it is possible to produce a device of compact structure and to generate a satisfactory dynamic focus voltage.

Abstract: A CRT protector circuit for detecting an overcurrent or an overvoltage to a CRT to protect the CRT. A detector circuit is provided for detecting the overcurrent and the overvoltage, and when such is detected an abnormality detection output from the detector circuit is supplied to a control circuit which in turn controls a horizontal output circuit. The operation of the horizontal output circuit, provided on a primary side of a flyback transformer is, instantaneously broken by the control circuit according to the abnormality detection output from the detector circuit. When the frequency of generation of the abnormality detection output becomes a predetermined value or more, the operation of the horizontal output circuit is continuously inhibited. Accordingly, when the abnormal condition is temporary, a normal high-voltage generating operation can be automatically restored.
