Abstract: An electrode assembly having a first electrode, a second electrode, and a separator therebetween, the first electrode, the second electrode, and the separator being wound in a jelly-roll shape is provided. The first electrode includes a first winding start portion, a first winding end portion, and a first coating portion having a first active material provided between the first winding start portion and the first winding end portion. The second electrode includes a second winding start portion, a second winding end portion, and a second coating portion having a second active material provided between the second winding start portion and the second winding end portion. A first electrode tab is provided at the first winding end portion of the first electrode. A first protective member is attached to a surface of the second winding end portion of the second electrode facing the first electrode tab.

Abstract: A jelly-roll type electrode assembly including a negative electrode, a first separator, a positive electrode, and a second separator that are wound together is provided. The negative electrode includes a negative electrode active material on a surface of a negative electrode collector and which has, on a first end thereof, a first negative electrode collector-exposed portion that is not coated with the negative electrode active material to expose the surface of the negative electrode collector. The negative electrode is wound together with the first separator such that the first negative electrode collector-exposed portion is disposed in a central region where the winding starts, and a negative electrode tab is coupled to the first negative electrode collector-exposed portion.

Abstract: A user equipment to display an augmented reality (AR) window includes a display unit to display an image and AR windows corresponding to objects included in the image, and a control unit to determine an arrangement pattern of the AR windows by adjusting at least one of a size, a display location, a display pattern, and a color of the AR windows and to control the display unit to display the AR windows in the determined arrangement pattern, together with the objects. A method includes detecting the object in the image, generating the AR window corresponding to the object, determining an arrangement pattern of the AR window based on an adjustment of an attribute, and displaying the AR window in the determined arrangement pattern along with the object.

Abstract: A multi-display device includes: a transparent first touch panel; a second touch panel of which at least a part overlaps the first touch panel; and an operation controller which operates the first and second touch panels. The operation controller senses a touch input of the first and second touch panels to determine and execute a function according to a state of the sensed touch input and an overlapped state of the first and second touch panels. The operation controller may selectively activate first and second functions of first and second touch panels, respectively, according to a touch recognition result and select and execute a third function linked with the first and second functions.
