摘要： A luminous display includes pixels arranged in rows and columns. Control signals that are used for controlling first switches for measuring parameters of pixel cells in a first row are also used to control second switches for programming pixel cells in a second row. In this way it is possible to use a single control signal for selecting one pixel cell for programming and simultaneously selecting another pixel cell for measuring. Programming and measuring are thus performed in a time staggered manner, while the addressing is moved to the respective next row. The programming is preferably voltage programming. In one embodiment the current through the pixel cell that is currently programmed is interrupted. In another embodiment the measuring is performed only after the transient current into signal holding means coupled to current control means has set.

摘要： An apparatus for generating a second signal having a clock based on a second clock from a first signal with a first clock comprises first and second means for sampling the first signal to determine whether the first signal has a predetermined logic state, wherein first means samples the first signal with the second clock, and second means samples the first signal with a clock phase shifted to the second clock. Means for generating the second signal generates the second signal based on the second clock if it has been determined by at least one means for sampling that the first signal has the predetermined state. Especially for time critical applications, such as a DDR-RAM, a valuable latency saving is provided by the present invention.

摘要： A circuit configuration includes two signal path sections that are used to program the delay of a signal path, in particular in DRAMs. The two signal path sections have different delays and can be driven in parallel at the input end. The two signal path sections can be connected to an output terminal via a multiplexer. A selection circuit includes two signal path sections which are connected between supply voltage potentials. The selection circuit has two complimentary transistors which are connected in series and has source-end programmable elements. These transistors can be driven by complimentary control signals. This permits the delay to be programmed flexibly with little expenditure on circuitry.

摘要： A circuit for an element of a light-emitting display is proposed. The element comprises a current control means, first and second switching means and a light-emitting means. In one embodiment, a signal holding means is provided. The arrangement of the first and second switching means of the element makes it possible to measure the electrical parameters of the current control means and of the light-emitting means during operation. A light-emitting display having a plurality of elements is furthermore proposed. The light-emitting display has a control circuit and a memory. The measured values of the electrical parameters of the current control means (4) and of the light-emitting means of the elements are used to correct the control signal S that is used to drive the elements. This enables a uniform brightness distribution in the case of voltage actuation and makes it possible to compensate for temporal changes in the light-emitting means. In addition, a method for actuating the elements and the light-emitting display is proposed.

摘要： In illuminated displays with lighting elements which are driven by means of a control voltage, the voltage drop on a supply line, which supplies two or more lighting elements, is compensated for. The currents for all of the light elements which are connected to a supply line, and the known resistances are used to calculate the potential profile of the supply line for this purpose. The control voltages for the light elements are changed such that the actual potential on the supply line for each element is taken into account. Fluctuations in the brightness of the illuminated display resulting from potential differences are avoided. One element of an illuminated display has a current control means, a signal retaining means, a light emitting means and means for interrupting the current flow through the light emitting means. The control voltage is adjusted with the current flow interrupted, so that no potential differences exist on the supply line. The signal retaining means hold the control voltage relative to the potential on the line at the respective position of the lighting element. An illuminated display has adjustable voltages for the supply lines. The voltages are chosen to be sufficiently high that the minimum required voltage for setting the desired currents through the lighting elements is achieved.
