Abstract
A display device and a display method are provided. The display device comprises a housing, a translucent module, a projecting unit and an object detection sensor. The housing comprises a containing space. The translucent module is disposed on the surface of the housing. The projecting unit is disposed in the containing space, and coupled to a controller. The projecting unit is configured to project projection light to the translucent module. The object detection sensor is disposed on the display device and coupled to the controller. When the object detection sensor senses that a moving object exists in a first preset distance range away from the housing, the object detection sensor outputs an object sensing signal to the controller. The controller controls the projecting unit and the translucent module based on the object sensing signal, so as to project a projection picture.
