Abstract: 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.

Abstract: A driving circuit for a display with display elements in rows and/or columns has a shift register, through which tokens are shifted. The shift register's parallel outputs are latched and enable switch cells depending on the tokens. Control signals are supplied to the switch cells which control the output signal in terms of pulse width and/or signal shape. Buffers output the signals to a connected display. Individual or groups of buffers are connected to different supply voltages. The shift register may have more than one input in order to allow for shifting tokens in parallel, e.g. to every second output, using only one clock cycle. Further, inputs are provided for inverting the travelling direction of the tokens, inverting the shape of the signal that is output or switching all outputs to a predetermined state.

Abstract: 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.

Abstract: 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.
