摘要： To suppress dissipation in monochrome LED displays, each frame is supplied at half the frame rate. In color LED displays, one color frame (e.g. green) is supplied at the normal frame rate and the other colors (red, blue) are supplied at slower frame rates. In a further embodiment, frame rates of all colors are based on the image to be displayed.

摘要： A display device has an array of display elements (2) each driven by an input provided on a data conductor (6). These inputs are generated by data conductor addressing circuitry (9) which has a plurality of controllable driver circuits (32,34,40), each for providing an input to an associated data conductor. The number of controllable driver circuits is at least one greater than the number required for providing data to all data conductors. A reference driver circuit (30) is used for calibrating at least one of the controllable driver circuits whilst the other controllable driver circuits provide inputs to the data conductors. This provides a reduction in the spread of driver circuit outputs by calibration of the driver circuits using a reference driver circuit.

摘要： A tracking index cathode ray tube circuit includes a tracking circuit connected to a shadowmaskless tracking cathode ray tube for deriving a tracking signal therefrom. The tracking circuit comprises a modulator demodulator circuit. The tracking signal from the CRT tube is thus modulated, AC coupled to a low voltage and demodulated to obtain a baseband tracking signal for use as a control signal for the electron beam spots on the screen of the CRT tube.

摘要： A receiver having, arranged in this order, an input section, an FM demodulator, to which a frequency-modulated input signal is applied, and an LF section, which FM demodulator includes a pulse shaper and a low-pass filter, the pulse shaper comprising a series arrangement of at least a load and a capacitance, the base-emitter junction of a transistor being arranged across the capacitance, and further including a switching device for charging and discharging the capacitance. The pulse shaper generates a low-noise pulse in that charging of a capacitance is started upon an edge of the input signal. The capacitance voltage is measured by a single transistor and when the transistor is turned on, the charging current of the capacitance is diverted via the transistor, so that the capacitance voltage is limited. The capacitance is discharged upon a second edge, after which the cycle is repeated. The output signal of the pulse shaper is a signal which varies with the current through the capacitance.

摘要： An autostereoscopic display device comprises a display arrangement such as an emissive display arrangement or an reflective display arrangement, with an array of spaced pixels. A light guiding arrangement has an array of light guide columns, with one column over each display pixel or over a group (such as a column) of pixels. The light guide columns comprise aside wall which tapers outwardly to define a funnel shape with the pixel at the smaller base of the funnel. The funnel provides collimation to reduce cross talk in the display, which is particularly problematic for 3D autostereoscopic displays.

摘要： A resonant matching circuit (310) for matching a resonant frequency of a wireless power transfer system to a frequency of a power signal comprises a switch (311) connected in parallel with a resonant element (302) of the wireless power transfer system; and a controller (312) connected to the switch (311) and configured to detect a zero-voltage level crossing of a signal flowing through the resonant element (302) and to close the switch (311) for a predefined amount of time upon detection of the zero-voltage level crossing, wherein closing the switch (311) for the predefined amount of time adds any one of an inductive value and a capacitive value to the resonant frequency of a wireless power transfer system.
