    摘要: An active matrix display comprises a select driver (SD) to drive select electrodes (SE), and a data driver (DD) to supply data (D) to data electrodes (DE). Pixels (10) are associated with intersections of the data electrodes (DE) and the select electrodes (SE). The pixels (10) comprise a light emitting element (L) and a pixel driving circuit (PD). The pixel driving circuit (PD) receives a power supply voltage (VB) via a power supply electrode (PE), and data (D) via a data electrode (DE) to control a brightness of the light emitting element (L). A power supply (PS) supplies the power supply voltage (VB). The power supply electrodes (PE) are arranged to supply the power supply voltage (VB) to the pixel driving circuits (PD) of lines of pixels (10) extending in the same direction as the select electrodes (SE) or in the same direction as the data electrodes (DE). The load (AL; MA; IL) on the power supply electrodes (PE) caused by the pixels (10) associated with the lines of pixels (10) is determined (LL), and the level of the power supply voltage (VB) is controlled (CO) dependent on the load (AL; MA; IL).

    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: A display device (500) having a plurality of picture cells (502) is controlled by adding a phase change to the regular cyclic inversion scheme. Thereby, it is possible to overcome the drawbacks of DC build-up due to, e.g., de-interlaced images and images comprising rotating symbols and “ticker tape”. The control involves receiving an image signal comprising image data relating to the picture cells. A respective electric field across each picture cell is controlled, in dependence on at least the image data, according to a first polarity inversion scheme where the polarity of the electric field is such that polarity inversion occurs at regular intervals, and according to a second polarity inversion scheme concurrent with said first polarity inversion scheme, where the polarity of the electric field such that polarity inversion occurs at pseudo-random intervals.

    摘要: The present invention relates to a multilayer record carrier, to a recording apparatus and to a method of recording on such a multilayer record carrier, and to a manufacturing method, wherein start and stop positions of recording areas at header portions (H) are shifted, in a lower recording layer (8), by a predetermined distance (Δ) such that recording and reading in/from the lower layer (8) is not affected by a variation in the transmissivity of the upper layer (6) at the transitions between the recording areas (R) and the header portions. The shifting may be obtained by extending gap portions or adding mirror areas to the header portions (H).

    摘要: A description is given of a disc-shaped rewritable optical information medium having an IPIM stack (2) comprising a phase-change recording layer (4) sandwiched between two dielectric layers (3,5), and a metal mirror layer (6). The thickness of the recording layer (4) increases gradually with increasing radius r. As a result, the complete erasure time CET of recorded marks decreases from the inner radius ri to the outer radius ro. Therefore, at a point closer to the outer radius marks can be recorded at a higher linear speed than at a point closer to the inner radius. This effect ensures that the recording medium can be used for recording at a constant angular velocity (CAV).

    摘要: A multi-layer record carrier and method of manufacturing thereof and recording thereon, includes data written in units of blocks on tracks of at least two information layers. A first guard field is written at the start of a data block and a second guard field is written at the end of the data block. The power in the focused spot in the deepest of the at least two information layers is maintained substantially at an optimal value, by setting the length of the first and second guard fields such that the end position of the second guard field of a preceding data block is located within the area of the first guard field of the succeeding data block. Thereby, gap portions between the first and second guard fields can be prevented. Alternatively, the length of the first and second guard fields is set to be approximately equal to the sum of half the diameter of a recording beam in the upper one of the at least two information layers when focused on the lowest one of the at least two information layers and a maximum allowed misalignment between the two layers. Thereby, the area through which the beam passes in the information layer is of a uniform nature, when user data is being read or written. The at least two information layers are aligned by optically measuring and aligning alignment marks, such as header spokes, at predetermined measuring points.
