Abstract
The invention provides display equipment, an optical component used for the display equipment, and a display method. A first surface located on the first side of the optical component has reflectivity and first transmittivity. A second surface located on the second side of the optical component has second reflectivity and second transmittivity. First light rays incoming from the outer side of the first surface to the first surface are reflected by the first surface or the second surface so as to form first reflection light rays entering the outer side of the first surface. Meanwhile, second light rays incoming form the outer side of the second surface to the second surface sequentially penetrate through the second surface and the first surface so as to form first transmitted rays entering the outer side of the first surface. The first reflectivity, the first transmittivity, the second reflectivity and the second transmittivity meet a first preset condition so as to enable an observer located on the outer side of the first surface to see the first reflection light rays and the first transmitted rays at the same time.
