Display device and display method

摘要

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.

1. Display device comprising
a holding device that can be fitted onto the head of a user, a multifunctional glass that is attached to the holding device and through which the user can perceive the actual surroundings when the holding device is fitted on and which has a first and second coupling-out section as well as a coupling-in section, an image generation module which generates an image and couples it into the multifunctional glass via the coupling-in section such that it is guided in the multifunctional glass to the first coupling-out section which effects a deflection of the image in the direction of the user when the holding device is fitted on his head such that the user can perceive the image in superimposition with the actual surroundings, a control unit for the image generation module, and a detector that is connected to the control unit and that measures an intensity of a portion of ambient light that is coupled via the first coupling-out section into the multifunctional glass, the portion of ambient light being guided along a light path in the multifunctional glass to the second coupling-out section and then coupled out of the multifunctional glass via the second coupling-out section to the detector, wherein the control unit controls the brightness during the generation of the image by means of the image generation module depending on the intensity measured by the detector.
