Abstract: An apparatus and a method for providing a partial display function related to a display device are provided. In a partial display mode, at least a part of operations of a display driver is inactivated in a non-display area of an entire display area of a display panel.

Abstract: A lithium-sulfur battery uses different binders that exhibit different swelling ratios in an electrolyte as cathode binders and thus having superior cycle performance and battery capacity. A first binder is a binder having a large swelling ratio in an electrolyte, and a second binder is a binder having a small swelling ratio in the electrolyte. The first binder is in direct contact with the active material. The second binder may indirectly contact the active material as being present between a plurality of first binders which are in direct contact with the active material.

Abstract: A flexible display device includes a flexible display panel, a flexible printed circuit board extending from the display panel, an integrated circuit chip that is mounted on at least one surface of the flexible printed circuit board and is configured to drive the display panel, and a protection member attached to a rear surface of the display panel. When the flexible printed circuit board is flexed to be partially positioned on the rear surface of the display panel, the protection member is positioned between the display panel and the integrated circuit chip. The flexible display device prevents the integrated circuit chip stacked with the display panel from making direct contact with the display panel using the protection member. Thus, even if the display device is deformed into, for example, a flexed or rolled state, it is possible to prevent the display panel from being damaged.

Abstract: The present invention provides a lithium-air hybrid battery and a method for manufacturing the same, which has a structure in which a liquid electrolyte electrode and a solid electrolyte electrode are stacked on both sides of an ion conductive glass ceramic. That is, disclosed is a lithium-air hybrid battery and a method for manufacturing the same, which has a structure in which a lithium metal negative electrode includes a liquid electrolyte and a porous air positive electrode comprising a carbon, a catalyst, a binder and a solid electrolyte are separately stacked on both sides of an impermeable ion conductive glass ceramic, and the liquid electrolyte is present only in the lithium metal negative electrode.

Abstract: A lithium battery is formed with a combination of an increased capacity negative electrode material capable of replacing a lithium metal electrode and a high capacity positive electrode material capable of realizing a high energy density. Particularly, the lithium secondary battery includes a negative electrode, and a positive electrode containing lithium oxide (Li2O) or lithium peroxide (Li2O2) as an active material.
