Abstract: The present disclosure relates to a cathode active material for an all-solid-state battery with a controlled particle size and a method for preparing the same. In particular, the cathode active material includes lithium and a transition metal, wherein the cathode active material has a single peak in the range of 1 ?m to 10 ?m as a result of particle size distribution (PSD) analysis.

Abstract: A method of manufacturing a stacked structure includes forming a first metal buffer layer including crystal grains on a base substrate, forming a second metal buffer material layer on the first metal buffer layer, and crystallizing the second metal buffer material layer to form a second metal buffer layer, wherein the second metal buffer material layer includes crystal grains, and a density of the crystal grains of the second metal buffer material layer is lower than a density of the crystal grains of the first metal buffer layer.

Abstract: Provided is a terminal including a body unit including a first area and a second area partitioned from each other, a speaker unit disposed in at least one of the first area and the second area, and a cover unit fixed to a surface of the body unit by a fixing member so as to cover the first area and the second area. The fixing member may include a fluid communication unit that connects the first area and the second area in fluid communication, so that the first area and the second area are provided as a resonance chamber of the speaker unit.

Abstract: A flexible display apparatus includes a flexible display unit including a front flexible surface to display an image and a rear flexible surface; a touch sensor unit to receive a touch input, the touch sensor unit disposed on the flexible display unit; and a guide unit to support the rear surface of the flexible display unit. A mobile terminal includes a flexible display apparatus including a flexible display unit and a guide unit, the guide unit supporting a rear surface of the flexible display unit; a support unit to support the flexible display apparatus to be unrolled in a first direction; and a body part to accommodate the support unit.

Abstract: A user interface apparatus may include a display unit to display a screen according to an application, a touch sensor to generate a touch signal if a touch is sensed on the display unit, a pressure sensor to generate a push signal if a push is sensed on the display unit, and an interface unit to determine an input according to the touch signal and the push signal, and to perform an operation of the application corresponding to the determined input.
