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.

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 display device includes an outer frame, a transparent cover, a back cover, a display module, and a separating structure. The outer frame has a display opening, the transparent cover covers the display opening, and the back cover is opposite to the display opening. The display module is disposed inside the outer frame and has a front surface facing the transparent cover and a rear surface facing the back cover. The separating structure is connected between the back cover and the rear surface of the display module. A first space formed between at least the transparent cover, the front surface of the display module, the outer frame, the back cover, and the separating structure is an enclosed space. A second space formed between at least the rear surface of the display module, the separating structure, and the back cover is connected to an outside and surrounded by the first space.

Abstract: An optical diffusion plate and a light source module are provided. The optical diffusion plate includes a light incident surface, a light emitting surface, at least one pattern region, and a reflection layer. The pattern region is located on at least one of the light incident surface and the light emitting surface. The reflection layer covers a portion of the pattern region. The pattern region includes a central region located at a central position, a plurality of first circular regions, and at least one second circular region. The central region is surrounded by the first circular regions and the second circular region alternatively, and perimeter of the central region is adjacent to one of the first circular regions. Coverage rates of the reflection layer at the second circular region and the central region are higher than coverage rates of the reflection layer at the first circular regions.

Abstract: A light source module including at least one optical film and a light source unit is provided. The light source unit is disposed under the at least one optical film, and a space is formed between the light source unit and the at least one optical film. The light source unit includes a plurality of light emitting elements and a plurality of secondary lenses. The light emitting elements are arranged along a direction parallel to the at least one optical film. The secondary lenses are correspondingly disposed on the light emitting elements and each of the secondary lenses has a patterned reflective layer. Each of the secondary lenses has a light hole radius R, a distance between a distribution range of the patterned reflective layer and a bottom of the corresponding secondary lenses is H, and the distribution range of the patterned reflective layer satisfies 1/R
