Abstract: A micro-structure film and a light emitting module are disclosed. A plurality of micro-structures with at least one predefined shape are uniformly distributed on at least one of surfaces of two opposite sides of the micro-structure film. The light emitting module includes a substrate, a plurality of light sources, and a package layer. The substrate has a first surface. The plurality of light sources are arranged on the first surface. The package layer is arranged on the first surface to contact with and cover the light sources. A plurality of micro-structures with at least one predefined shape are uniformly distributed on an other side of the package layer opposite to the first surface.

Abstract: A display apparatus includes a light-transmitting structural plate, some optical microscopic structures, an optical film, a base plate and some light emitting elements. The light-transmitting structural plate has a first side and a second side opposite to each other. The optical microscopic structures are regularly arrayed and formed on the first side or the second side. The optical microscopic structure has an inclined surface connecting at a connecting line and forming an angle ranging between 30 degrees and 150 degrees with a corresponding inclined surface of an adjacent one of the optical microscopic structures. The optical film is located on the first side. The base plate is separated from the second side by a space. The light emitting elements are located inside the space and disposed on the base plate. The light emitting elements respectively emit a light ray to the light-transmitting structural plate.

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.
