Abstract

A display device has a holding device wearable on a user's head and holding a multifunctional glass that comprises a first and second coupling-out section and a coupling-in section, an image generation module that generates and couples an image into the multifunctional glass through the coupling-in section to the first coupling-out section redirecting the image in the direction of the user such that the user can perceive the image in superimposition with the real environment, a control unit for the image generation module, and a detector which is connected to the control unit and which measures the intensity of ambient light coupled through the first coupling-out section to the second coupling-out section and coupled out of the multifunctional glass through the second coupling-out section. The control unit controls the brightness of the image of the image generation module, the brightness controlled according to the intensity measured by the detector.
