Abstract: A display device includes a light emitting area and a sub-area disposed at a side of the light emitting area, a measurement area disposed in the sub-area, measurement patterns and a first electrode extension portion being disposed in the measurement area, a first electrode and a second electrode that are disposed in the light emitting area and spaced apart from each other, and face each other, a first insulating layer disposed on the first electrode and the second electrode, at least a part of the first insulating layer being disposed on the first electrode extension portion, and at least one light emitting element having ends disposed on the first electrode and the second electrode in the light emitting area. The measurement area includes a first measurement area in which a first measurement hole exposing a part of an upper surface of the first electrode extension portion is disposed.

Abstract: Disclosed is a technique for switching from a master node to a secondary node in a communication system. A method of a first communication node may comprise: adding the first communication node as a primary secondary cell (PSCell) to a second communication node through dual connectivity (DC); generating a first user plane path for smart dynamic switching (SDS) and a first instance for supporting the first user plane path according to a request from the second communication node; transmitting information on the first user plane path and the first instance to a terminal; receiving user data based on the first user plane path from the terminal as the first instance; and transmitting the user data to a core network using the first user plane path.

Abstract: An infrared heat source module is configured to minimize problems such as wrinkles or cracks in electrodes even if the patterns of a coated part and an uncoated part of the electrodes present in a current collector vary. The module improves a drying efficiency of the coated part of the current collector. An electrode using the infrared heat source module is manufactured by a process.

Abstract: A microwave oven has a main body including a cooking compartment, and a component compartment in which a heating component is installed. An outer casing encloses the main body. A fan is provided at the component compartment corresponding to the heating component, and blows outside air to cool the heating component. An air inflow part is formed on the outer casing adjacent to the fan and through which the air from the cooling fan flows. A partitioning wall of a round shape separates the cooking compartment and the component compartment, wherein the fan is inclined with respect to the cooking compartment so that the air flowing through the air inflow part is guided toward the heating component along the partitioning wall.
