A display device, according to an embodiment of the present disclosure, includes a substrate, a light emitting unit comprising a light emitting element mounted on the substrate and a lens placed on the upper side of the light-emitting element, a reflective layer arranged on the upper surface of the substrate, an optical sheet arranged on the upper side of the reflective layer and disposed at a height spaced apart from the light emitting unit; and a display panel placed on the upper surface of the optical sheet, wherein a center portion of the upper surface of the lens is recessed at a predetermined depth and formed in the shape of a continuous straight line, and the upper surface thereof has an aspheric shape that is curved at a predetermined curvature from the center portion toward the edges, so as to have an anisotropic distribution of light.

A solid state disk is provided, including: a main body, including a shell portion, a substrate which is disposed on the shell portion and a memory module which is disposed on the substrate, the substrate including a transmission port, the memory module being electrically connected to the transmission port; at least one light-emitting portion, disposed on the substrate and electrically connected to the transmission port; at least one scattering light-guiding portion, arranged on the substrate correspondingly to the light-emitting portion without covering any part of the at least one light-emitting portion, each said scattering light-guiding portion having a scattering structure, at least one part of light emitted from each said light-emitting portion projecting toward the scattering structure and the light being scattered evenly via the scattering light-guiding portion to an exterior of the solid state disk.

A display device and a mold frame are provided. The display device includes a mold frame which is disposed above a light source member and having a sidewall portion, a mounting portion protruding inward from a lower end of the sidewall portion, and an inclined portion comprising an upper inclined portion and a lower inclined portion disposed below the upper inclined portion, the upper inclined portion extending downward and inward from a protruding end of the mounting portion and located on an upper portion of the inclined portion; and a display panel disposed above the mold frame, wherein the mold frame comprises a light transmitting portion configured to transmit incident light and a light reflecting portion configured to reflect the incident light, the light transmitting portion comprises the sidewall portion, the mounting portion, and the upper inclined portion, and the light reflecting portion comprises the lower inclined portion.

In one aspect, a back-lit digital photograph frame system is provided. A display assembly includes: a tray frame comprising a back surface of the display assembly as a backside enclosure; an optical acrylic block comprising a front surface of the display assembly; a light guide plate, wherein the light guide plate is located between a photographic print and a reflective backing paper, the photographic print, wherein the photographic print is located between optical acrylic block and the light guide plate, and a reflective backing paper, wherein the reflective back paper is located between the light guide plate and the tray frame, wherein the tray frame, the optical acrylic block, the light guide plate, the photographic print and the reflective backing paper are set in a vertical stack, and a base mount comprising an opening that receives the display assembly and holds the display assembly in a vertical position orthogonal to a receiving surface of the base mount, wherein the display assembly is held in place with a compression fit, and wherein the base mount further comprises a light emitting diode (LED) strip.

A system and method for controlling amount of light emitting from an illuminating screen including: a frame defining a space, a screen mounted onto a front side of said frame, a back plate mounted onto a back side of the frame, opposite the front side, at least one light source and a concealing element. The at least one light source is positioned within the space defined by the frame and is configured to illuminate the screen. The concealing element is located inside the space defined by the frame and is configured to block light from illuminating the screen. The amount of light emitting through the screen is controlled by a ratio between the area of the concealing element positioned in a section located between the at least one light source and the screen, and the total area of the section.
