Abstract: A mirror device (1) which can be simultaneously used for display purposes based on e.g. an LCD display (5) with a polarizing mirror (2) placed in front of it. The orientation direction of a retardation layer (31, 32) is aligned with respect to the polarization direction of the polarizing mirror to give optimal optical performance.

Abstract: A display including: a display surface (108, 300) for displaying content to a user; a computer system (110) for supplying the content to the display surface (108, 300) for display in a content window (112, 306) on the display surface (108, 300); and a recognition system (128) for recognizing a gesture of a user and defining at least one of a size, location, and content of the content window (112, 306) on the display surface (108, 300) based on the recognized gesture. The display can be a display mirror (108) for reflecting an image of the user at least when the content is not being displayed. Furthermore, the gesture can be a hand gesture of the user.

Abstract: A mirror device (1) which can be simultaneously used for display purposes, based on e.g. an LCD display (5) with a polarizing mirror (6) placed in front of it. The polarizing mirror (2) has the characteristics that it does not disturb the transmission of the light from the display (5), but does reflect the light from outside the area of the screen. The polarizing mirror (2) is embedded in a conventional mirror (4,8).
