摘要： Screen burn on televisions having Internet browser capability is avoided by removing the conventional static icons such as toolbars and buttons from the default browser and replacing their functions with keyboard keys. The invention is especially useful in projection televisions and with keyboards which have keys assigned to browser functions. Favorite URLs can be mapped to a favorite key by holding down the favorite key while a favorite web page is displayed.

摘要： Unintentional emissions are controlled responsive to the spectral content of the display signal. A video display apparatus comprises a cathode ray tube responsive to a video signal. A processor (50) controls a bandwidth of the video signal (v,g,b) coupled to the cathode ray tube in response to an emission control signal (CONT. 1). A generating means (20) is coupled to the processor (50) for generating the emission control signal (Ve) responsive to a component of the video signal (Y).

摘要： A cathode ray tube video display comprises a cathode ray tube (CRT) for displaying a video signal (Vin) coupled thereto. A cathode ray tube electron beam blanker (201) is coupled to the cathode ray tube (CRT) and is responsive to a blanking trigger signal (GK) for blanking an electron beam (e) within the cathode ray tube (CRT). A blanking controller (200) is coupled to the cathode ray tube electron beam blanker (201) and generates the blanking trigger signal (Gk) for controlling electron beam blanking, wherein the electron beam (e) is blanked for different durations in accordance with one of a hot and cold start condition.

摘要： A high voltage circuit for a display device incorporating a cathode ray tube is provided. The circuit comprises a high voltage generator, having a transformer and a periodically actuated switch. The circuit further comprises means for obtaining a sensed signal, representing the high voltage applied to the cathode ray tube, and a comparator for comparing a reference signal and the sensed signal representing the high voltage and for outputting a fault signal indicative of excessive high voltage. A memory stores representations of a set of reference values, each reference value being associated with a selectable operating mode of the display device. Another means supplies the reference signal corresponding to the reference value associated with a selected operating mode. Upon occurrence of the fault signal the high voltage generator is disabled.

摘要： A method and device are described for detecting whether a flash (F) has occurred in the high voltage part of a combined high voltage and horizontal deflection circuit (100) in an apparatus comprising a cathode ray tube (CRT), such as for instance a television set, a monitor, etc. The possible flash is detected by checking the fly-back pulse (70) of the horizontal deflection circuit (16) for deviations that reflect the occurrence of a flash. One possible distortion indicative for the occurrence of a flash is bouncing of the fly-back pulse. Another possible distortion indicative for the occurrence of a flash is collapse of the fly-back pulse. Another possible deviation indicative for the occurrence of a flash is a substantial decrease of the storage time (τS)) of the line deflection transistor (30).

摘要： An ultor voltage switching power supply for a cathode ray tube is energized by a low voltage switching power supply. A switching transistor of the ultor voltage switching power supply is disabled when a screen of the cathode ray tube is blanked. An anode capacitance of the cathode ray tube that develops the ultor voltage discharges via a bleeder resistor, when the switching transistor is disabled. As a result, a transient decrease occurs in the ultor voltage. The decreased ultor voltage tends to maintain the screen blanked.

摘要： A line deflection circuit includes circuitry for protecting the line output transistor (Q1) from failure due to an over-current condition. The circuitry includes a current detector (R3) for detecting the current in the collector-emitter path of the line output transistor (Q1), and an interrupter (SCR) for interrupting the drive signal (Vd) to the line output transistor (Q1) when the detected current exceeds a predetermined level.

摘要： A spot killer circuit for a cathode ray tube (1) having blanking function is configured to be provided with a positive voltage source, a negative voltage source, two diodes (D1, D2), condensers (C1, C2) and a resistor (R3) in order to perform blanking in horizontal scanning or vertical scanning by using a first grid (G1) of the cathode ray tube (1). In the configuration, the two diodes (D1, D2) are inserted in series between the negative voltage source and the first grid (G1), and a first condenser (C1) is inserted between a junction of the two diodes (D1, D2) and the positive voltage source. A resistor (R3) is connected in parallel with the diode (D2) connected to the first grid (G1), and a blanking signal is applied to the first grid (G1) through a second condenser (C2).
