Abstract: An anti-peep light source module and an anti-peep display device having an anti-peep function and good image quality are provided. The anti-peep light source module includes a light guide plate, a first light emitting element, a second light emitting element, a plurality of optical microstructures and a first surface. The light guide plate has a first light incident surface and a second light incident surface. Each of the optical microstructures has a first optical surface facing the first light incident surface and a second optical surface facing the second light incident surface. A magnitude of a first included angle between the first optical surface and the first surface and a magnitude of a second included angle between the second optical surface and the first surface gradually change as getting farther away from the first surface.

Abstract: A transparent display device includes a transmissive light valve panel, a transparent plate and at least one light emitting assembly. The transmissive light valve panel has a display surface. The transparent plate is disposed with respect to the transmissive light valve panel to form an optical space between the transparent plate and the transmissive light valve panel. The at least one light emitting assembly is disposed beside the optical space and adapted to generate light into the optical space. A light pattern of the light emitted from the light emitting assembly and directed to the optical space has at least one maximum peak in an angular range of ±15° with respect to a direction parallel to the display surface of the transmissive light valve panel.

Abstract: A reflective display apparatus includes an LGP, at least one light-emitting element, a reflective display panel, a first light-absorbing portion, and a first gel layer. The light-emitting element is beside a light-incident surface of the LGP. The LGP has a first region and a second region. The first region is between the light-emitting element and the second region. The reflective display panel is under a bottom surface of the LGP. The first light-absorbing portion is at a side of one of a bottom surface and a top surface of the LGP. The first gel layer is between the first light-absorbing portion and the LGP. The light-absorbing portion is in the first region. A display region of the reflective display panel is in the second region. In the first region, the bottom surface or the top surface where the first light-absorbing portion is disposed is a plane surface.

Abstract: A display box is capable of supporting an electronic device. The electronic device is capable of emitting an image beam. A display box includes a box, a light-transmitting plate and a pivoting carrier. The box has a top-side opening and a viewing opening. The light-transmitting plate is obliquely arranged in the box and is capable of reflecting the image beam passing through the viewing opening to a target. The pivoting carrier has an accommodating recess and a first pivot axis. The pivoting carrier is disposed on the box. The pivoting carrier is pivoted beside the top-side opening by the first pivot axis. The electronic device is disposed in the accommodating recess, wherein the pivoting carrier rotates by the first pivot axis to make the electronic device face different positions.
