Abstract: The present invention provides a display device, which includes a frame having an accommodating cavity and a display module disposed in the accommodating cavity. The display module includes a first light source, an optical unit, an imaging unit arranged on a side of the optical unit facing away from the first light source, and a lens array arranged on a side of the imaging unit facing away from the first light source. Corresponding to a preset pattern, light emitted by the first light source passes through the optical unit, the imaging unit and the lens array to form a default floating image in a floating display area outside the accommodating cavity. In addition, the present invention also provides a non-contact key and an input device including the above display module.

Abstract: A floating image generation device is disclosed, which includes a light source, an image generation module, and a floating image generation unit. The image generation module is disposed above the light source and includes a shading unit and an image generation unit. The shading unit is capable of changing light transmissivity state. The image generation unit is disposed above the shading unit. The floating image generation unit is disposed above the image generation unit. The light source emits a light passing through the shading unit, the image generation unit, and the floating image generation unit to generate a first floating image when the shading unit is in a first light transmissivity state. The light source emits a light passing through the shading unit, the image generation unit, and the floating image generation unit to generate a second floating image when the shading unit is in a second light transmissivity state.

Abstract: The present invention provides a display cover, which includes a light transmission layer, a window pattern disposed on the light transmitting layer, at least one light source disposed on the light transmission layer or the window pattern, and a light conduction layer disposed on the light transmission layer to cover the window pattern and the at least one light source. The window pattern is designed corresponding to a predetermined pattern, so as to define a light transmission window of the predetermined pattern in the light transmission layer. Moreover, at least one light guide structure is disposed on one side of the light conduction layer facing away from the light transmission layer. The at least one light guide structure is configured to at least partially guide light emitted from the at least one light source to the light transmission window.
