摘要:
An arrangement including a light-emitting diode array made up of light-emitting diodes, each light-emitting diode being switchable on and off with the aid of a controllable switch, and including a current source for supplying the light-emitting diode array with current. The arrangement including an interface, to which an input signal having image information for an image, which is displayable with the aid of the light-emitting diode array, may be applied, and the interface converting the input signal into digital signals in which information is contained for switching the controllable switches on and off. The arrangement including a counter, with the aid of which it is possible to detect how many switches are closed or are to be closed within a clock pulse. The current supplied by the current source is controllable as a function of the counter reading.
