DISPLAY DEVICE HAVING A HOLDING DEVICE THAT CAN BE PLACED ON THE HEAD OF A USER |
摘要 |
A display device includes a holding device that can be placed on the head of a user. An image-generating module and an imaging lens system can be secured on the holding device. The latter includes a spectacle lens with a curved front and a curved back. It projects the image generated when the holding device is placed on the head such that the user can perceive it superimposed on the surroundings. Light from the image-generating module is coupled into an optical channel in the spectacle lens. It is conducted in the optical channel to an exit section and coupled via the exit section out of the spectacle lens. The optical channel includes in the region of the front and back a Fresnel structure with a plurality of facets on which the light conducted in the optical channel is reflected, and which are aligned parallel to one another. |
