Abstract: The method for preparing a super absorbent polymer according to the present disclosure has a feature that it is possible to reduce the generation of a fine powder during production of the super absorbent polymer while maintaining excellent physical properties of the super absorbent polymer, including centrifuge retention capacity (CRC) and vortex removal time.

Abstract: A display apparatus includes a base substrate, a light emitting structure disposed on the base substrate, and a thin film encapsulation layer disposed on the light emitting structure and including at least one inorganic layer and at least one organic layer. The at least one inorganic layer includes a high density layer having a density of greater than or equal to about 2.0 g/cm3 and a low density layer having a density of less than about 2.0 g/cm3. The high density layer and the low density layer are in contact with each other.

Abstract: Disclosed herein are a cooperative driving method based on driving negotiation and an apparatus for the same. The cooperative driving method is performed by a cooperative driving apparatus for cooperative driving based on driving negotiation, and includes determining whether cooperative driving is possible in consideration of a driving mission of a requesting vehicle that requests cooperative driving with neighboring vehicles, when it is determined that cooperative driving is possible, setting a responding vehicle from which cooperative driving is to be requested among the neighboring vehicles, performing driving negotiation between the requesting vehicle and the responding vehicle based on a driving negotiation protocol, and when the driving negotiation is completed, performing cooperative driving by providing driving guidance information for vehicle control to at least one of the requesting vehicle and the responding vehicle.

Abstract: An organic light-emitting diode (OLED) display is disclosed. In one aspect, the OLED display comprises a display substrate, an encapsulation substrate, and at least one spacer. The display substrate includes a non-pixel area, wherein a plurality of via holes is formed in the non-pixel area. The encapsulation substrate is formed over the display substrate. The spacer is formed between the display substrate and the encapsulation substrate so as to maintain a gap therebetween, wherein the spacer at least partially covers at least one of a plurality of via holes.
