A light emitting module is disclosed. The light emitting module includes a board, a plurality of light sources, and a package layer. The board includes a first surface. The plurality of light sources are disposed on the first surface. The package layer is disposed on the first surface, which contacts and surrounds the light sources. A plurality of micro-structure areas are defined on the face of the package layer opposite to the first surface, wherein the micro-structure areas are disconnected with each other. The orthographic projection of each micro-structure area on the first surface covers the respective orthographic projection of one of the plurality of light sources on the first surface. The package layer concaves to form a plurality of micro-structures toward the first surface in the micro-structure areas.

Light emitting module

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.

Optical plate and display apparatus

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.

Display device, non-contact key, and input device

A backlight module includes a base plate, a plurality of light-emitting elements and a plurality of lenses. The light-emitting elements are disposed on the base plate. The lenses are disposed on the base plate and respectively correspond to the light-emitting elements. Each of the lenses has a side surface and a plurality of diffusing portions. The diffusing portions are located on the side surface. At least one of the diffusing portions of each of the lenses is located between adjacent two of the corresponding lenses.

Backlight module

A light-emitting device including a light-emitting unit and a second lens is provided. The second lens includes light-emitting surface, bottom surface, side surfaces and accommodation hole. The bottom surface is disposed opposite to the light-emitting surface, and the side surfaces are respectively connected to the light-emitting surface and the bottom surface. The accommodation hole passes through the second lens and accommodates light-emitting unit. A light-emitting module and a backlight module are also provided.
