摘要： A method for driving pixels in a display device with an image signal is disclosed wherein the image signal comprises grey level information of an image to be rendered by the display device. The method comprises: dividing the image signal into sections, each section having a duration of a section period; dividing the section period into a plurality of adjacent, weighted sub-section periods; selecting for each of the pixels to be driven during the section period a sequence of adjacent sub-section periods in dependence on the grey level information, the selectable sequences lacking a common starting and ending point; driving the pixels during the sequences adjacent sub-section periods. The method may be applied to displays driven by a pulse width modulated signal, such as sub-field as well as sub-line operated displays including plasma display panels, dynamic foil displays and passive displays.

摘要： A predetermined synchronization pattern (40), a so-called VFO field, in, for example, the headers 3 of an information carrier. The predetermined synchronization pattern contains a first part with marks having a first length of (d+1) times the channel bit length, and spaces having a second length of (d+1) times the channel bit length, and a second part with marks having a third length of (k+1) times the channel bit length and spaces having a fourth length of (k+1) times the channel bit length and a third part, which third part contains marks having a length of (k−d) times the channel bit length and spaces having a length of (k−d) times the channel bit length. This sequence of patterns is advantageous for setting the dynamic range of an Automatic Gain Controlled (AGC) amplifier located within a device reading the information carrier.

摘要： An optical record carrier is described comprising a track for carrying data encoded in optical marks. A parameter of the track has a periodic variation for generating a varying signal when scanning the track, for example a variation of the center of a pre-groove usually called wobble. The track further comprises reference elements, e.g. headers, interrupting the periodic variation. The phase of the periodic variation after the reference elements is indicative of a property of the record carrier for controlling the scanning of the record carrier in dependence of said property. In particular the phase may indicate whether or not the bottom of the pre-groove is closer to the scanning beam entry side of the disc. Further a scanning device is described comprising a detector for detecting said phase based on the varying signal. The device adapts its scanning control means to the indicated property.

摘要： The invention provides an illumination system comprising a light-emitting device which excites a first luminescent element, which forms part of the light-emitting device. The light emitted from the first luminescent element and/or the light emitted by the light-emitting device excite a second luminescent element, physically separated from the light-emitting device. By employing two luminescent elements, the first element in the light-emitting device, and the second element physically separated from the light-emitting device, such as on a cover plate, the conversion of light produced by the light-emitting device is performed at both a “local” and a “remote” location, respectively, and the amount of luminescent material required at the remote location may be reduced compared to the situation of the prior art where the light conversion was only performed at a remote location.

摘要： Disclosed is a driver that includes a main power supply that has outputs coupled across a string of light emitting diodes to supply a main current. A secondary power supply is coupled to a junction between successive light emitting diodes in the string to supply or withdraw a delta current from the junction. The delta current is at least five times smaller than the main current. A controller controls the secondary power supply to generate the delta current to obtain a desired spectral composition of the mixed light emitted by the string.

摘要： The present invention relates to a method for determining drive values for driving a lighting device at a desired brightness and color. The method comprising the steps of determining a first luminous flux weight ratio based on the desired color and a first drive current for driving each of the differently colored LEDs, determining a first luminous flux for each of the differently colored LEDs based on the desired brightness and the first luminous flux weight ratio, comparing, for each of the differently colored LEDs, the first luminous flux with a nominal luminous flux for a plurality of different drive currents, selecting, for each of the differently colored LEDs, a preferred drive current that at least can produce the first luminous flux, determining a second luminous flux weight ratio based on the desired color and the selected drive currents for each of the differently colored LEDs, determining a second luminous flux for each of the differently colored LEDs based on the desired brightness and the second luminous flux weight ratio, and determining a duty cycle for each of the differently colored LEDs at the selected drive currents, wherein the selected currents at the determined duty cycles produces the second luminous flux for each of the differently colored LEDs. The present invention provides for the possibility to limit the number of necessary computational steps for determining preferred drive currents. Furthermore, an increase in number of current level and/or differently colored LEDs would only slightly increase the computational cost.

摘要： In an active matrix electroluminescent display device, an overall brightness level of an image to be displayed in a frame period is determined. A drive transistor of each pixel is controlled in dependence on an input drive signal for the pixel and on the overall brightness level, for example using a signal processor (30) to vary the pixel drive signals.This arrangement can control the pixels to limit the maximum currents drawn by the pixels, thereby limiting the cross talk effects resulting from voltage drops along row or column conductors. If an image is bright, the pixel drive levels across the image (or at least a part of the image) can be reduced, so that the maximum brightness is reduced.

摘要： A driving circuit (10) for driving a plurality of light sources (1) arranged in a series configuration (2) is described. A controllable current source (20) is connected to said series arrangement of light sources. Each light source (1(i)) is bridged by a corresponding controllable switch (25(i)). A controller (30) controls the operation of the current source (20) to set a current level and controls the operative states of the respective switches (25(i)) in order to individually control the light output of the corresponding light sources. The controller (30) is capable of individually setting the switch control signals (SL(O) for the respective switches (25(i)). Especially, the controller (30) is capable of boosting the light output of one selected light source (1(x)) while maintaining the light output of other light sources in the series arrangement (2). To this end, the current level is increased while the other light sources are dimmed.
