Optical vehicle display having a set of LEDs arranged in a matrix and having a control circuit which acts as a controllable current source and as controllable voltage source, so that a constant current can be applied for each LED and the respective voltage is established accordingly. An optical vehicle display designed in this way permits a design as a taillight, brake light, flashing indicator and the like in a motor vehicle with favorable production at the same time due to reduced faulty assembly and simple adjustment of the light values.
