The Magic Mirror is an LCD display, which is functioning as a normal display while it is activated and as a full mirror while it is deactivated. The surface glass/mirror is constructed to be combined with the LCD display and it complies with the necessary surface, hardness and tension requirements.
The position of the display area within the glass/mirror surface is freely selectable. It is only limited by the display, which has to be installed on the rear side of the glass. So, the factors that have to be considered are both the size of the image area according to the available LCD display sizes and the dimensions of the display external casing.
