Method of operating at least two laser devices and display device

A display device, comprising:

• a memory in which target color coordinates and/or a plurality of target brightness are stored for a plurality of illuminable pixels of the display device;
• a first and at least one second laser device, which are designed while being supplied by a supply current to generate laser light for illuminating the pixels in a pulsed mode;
• a detector circuit coupled to at least one of the first and at least one second laser device;
• a supply circuit for providing an adjustable supply current to the first and at least one second laser device;
• a control circuit which is coupled to the detector circuit and the supply circuit and is designed to supply a defined voltage in the reverse direction to the laser device coupled to the detector device during a first time period and to detect a voltage drop across the coupled laser device by means of the detector circuit and to set the supply current for at least one of the first and at least one second laser device during a second time period based on the color location and/or the target brightness for an image point to be illuminated and the detected voltage drop
• wherein the first and at least one second laser device comprise laser diodes.
