Abstract: Provided is a backlight unit and a display device including the backlight unit. A backlight unit may include a frame, at least one substrate, a plurality of light sources installed over the at least one substrate, a reflecting sheet, and an optical sheet. The reflecting sheet may include a first sheet region, a second sheet region that extends outward from the first sheet region and inclined relative to the first sheet region, and a third sheet region provided in the first sheet region and having a protrusion that protrudes from the first sheet region toward a front side of the backlight unit. The reflecting sheet may include a plurality of patterns provided on the second sheet region and the third sheet region configured to reduce reflectivity of light emitted from the plurality of light sources. The plurality of patterns may be formed by dots arranged to form the pattern.

Abstract: A display apparatus may be provided that includes a display module, a housing, at least one speaker module within the housing, and at least one reflector disposed adjacent to the at least one speaker module. The at least one reflector may have an inclined acoustic reflection surface exposed to a front side of the display module when the sounds are emitted from the at least one speaker module. The at least one speaker module may be disposed in parallel to a horizontal or vertical direction of the housing.

Abstract: A display device includes a frame, a substrate positioned on the frame, and a plurality of light sources mounted on the substrate, and a display panel positioned on the substrate, wherein the frame is divided into a plurality of parts, and wherein the substrate is provided in at least one part, and the at least one part of the substrate is positioned on the at least one part of the frame. Since the frame is divided into a plurality of frames, the display device has excellent heat dissipation effect and a less amount of foreign objects such as dust, or the like, may collect due to ventilation.

Abstract: A display apparatus and a control method thereof are provided. The display apparatus includes a user manipulation unit on which a keypad is mounted, a display unit controlled by manipulating the keypad, and a lighting unit movably mounted on the display unit, the lighting unit emitting light to the outside of the display unit.

Abstract: A photovoltaic power generation system, includes: a photovoltaic power generator configured to output an electrical power generated using light; an inverter configured to convert the generated electrical power into an alternating current (AC) power and supply the AC power to a commercial power source or to a load; a capacitor configured to store the generated electrical power; and a monitor configured to direct the generated electrical power to the inverter or the capacitor based on an operation mode selected by a user.
