Abstract: A display device includes a display panel including a rear surface and a front surface, where the front surface is provided with a display surface and including a folding axis extending in a first direction, a first barrier member disposed on the rear surface of the display panel and having a modulus of about 1 GPa to about 300 GPa, a first coupling member disposed on a rear surface of the first barrier member, and a metal plate disposed on a rear surface of the first coupling member and including a first plate portion and a second plate portion which are arranged in a second direction crossing the first direction and a connection portion connecting the first plate portion and the second plate portion, where the first coupling member does not overlap the connection portion in a plan view.

Abstract: A cylindrical secondary battery and a manufacturing method of a secondary battery are provided. A manufacturing method of a cylindrical secondary battery includes: winding an electrode assembly to expose a first electrode uncoated portion and a second electrode uncoated portion to opposite ends in a longitudinal direction; bending at least some portions of the first electrode uncoated portion and the second electrode uncoated portion of the electrode assembly in a direction by pressing the first electrode uncoated portion and the second electrode uncoated portion; welding electrode collector plates to ends of the bent first and second electrode uncoated portions; and inserting and sealing the electrode assembly into a cylindrical case.

Abstract: Provided an electronic device including a main body and a kit connected to the main body, and the main body includes a battery, a first motor, an electric wire connected to the battery, and a first controller connected to the electric wire, the kit includes a second motor supplied with power through the electric wire, an inverter connected to the second motor, and a second controller connected to the electric wire and configured to control driving of the inverter, and the second controller is configured to transmit information to the first controller through switching frequency control of the inverter and control a switching frequency of the inverter so that a current associated with the second motor is greater than zero in a section in which transmission of the information is performed.

Abstract: A protective window includes a glass substrate which faces a display surface of an image-generating panel and has a thickness of about 20 micrometers to about 80 micrometers; a protective film which faces the display surface of the image-generating panel with the glass substrate therebetween; an adhesive layer which is between the protective film and the glass substrate and combines the protective film with the glass substrate; and a protective layer which covers an edge portion of the glass substrate. A thickness of the protective layer which covers the edge portion of the glass substrate is equal to or less than about ? of a thickness of the adhesive layer which combines the protective film with the glass substrate.

Abstract: A back pressure structure of a scroll compressor having a fixed scroll forming a plurality of compressive chambers together with an orbiting scroll in its casing; including: a suction pressure space having a predetermined volume formed at one side of the fixed scroll; a suction hole formed for guiding a part of an intermediate gas filled in an intermediate pressure space filled in the rear side of the orbiting scroll to the suction pressure space by passing through the fixed scroll; a vent hole formed at the other side of the suction pressure space for guiding the intermediate pressure gas flown into the suction pressure space through the suction hole to the outermost compressive chamber which has a relatively low pressure; and a back pressure control valve elastically supported by an elastic member in the suction pressure space to open and close the suction hole, and receiving almost the same pressure no matter that it is opened or closed, according to which an intermediate pressure space between a main fram
