Abstract: A circuit arrangement for a picture display device for generating a sawtooth-shaped line deflection current, at least two controllable deflection switches which are switched at line frequency and are arranged in series. As a result thereof the line deflection coil is connected to a trace capacitor during the trace period. During the retrace period the two switches are rendered non-conductive substantially simultaneously and the coil, the trace capacitor and a retrace capacitance form a resonant network the elements of which determine the duration of the retrace period. Supply energy is supplied from a supply voltage source by means of a supply winding which is divided in at least two winding portions which are each connected by means of one end through a supply diode to the resonant network and by means of the other end to a deflection switch and are coupled to the source via a controllable supply switch, which switches at the line frequency. During at least a portion of the trace period the supply switch is in the conducting state while the supply diodes are non-conducting and are non-conducting during the remaining portion of the line period while the supply diodes conduct. The conduction period of the supply switch may be adjustable to adjust the amplitude of the deflection current and also to stabilize this current versus fluctuations of the supply voltage. The said amplitude does not depend on the line frequency.

Abstract: In the market, there is a tendency towards picture tubes with a super flat screen. Due to the flat screen, it is becoming increasingly difficult to meet the even tighter specification on North/South raster distortion (N/S distortion), the tighter specification being caused by a growing importance of text display and high resolution displays. A deflection correction circuit is provided which compensates for a N/S distortion by inducing a correction current (Icv) through a vertical deflection coil (Lv). The correction current (Icv) can be injected in the vertical deflection coil (Lv) via an injection transformer (Ti) coupled in series with the vertical deflection coil (Lv). The injection transformer (Ti) is driven via an output stage (3) by a waveform generator (1,2). The waveform generator (1,2) generates a voltage waveform (M) built up out of substantially straight line sections. The deflection coil (Lv) integrates the voltage waveform (M) into a current waveform (Icv) having substantially parabolic sections. Such an inexpensive and flexible deflection correction circuit can be used to compensate for top/bottom and/or seagull N/S distortion, or for correction of convergence distortions. The deflection correction circuit can be a discrete or an integrated circuit.

Abstract: One of the problems in display devices is that the black level is different for each type of display tube and is also dependent on temperature and ageing. The display devices hitherto known with black level setting circuits apply one control voltage to the relevant cathode during the field blanking interval, whereafter the cathode current is measured and subsequently compared with a reference current. Subsequently, the black level is adapted until the measured current approximately corresponds to the reference current.The display device now includes a black level setting circuit with a control circuit adapted to successively apply at least two control voltages in a predetermined ratio to the cathode. Moreover, the black level setting circuit includes a correction circuit for supplying a correction value dependent on the ratio between the currents generated in the relevant cathode in response to the at least two control voltages.
