Abstract: A display may include flexible substrate, a blocking layer on the flexible substrate, a pixel on the flexible substrate and the blocking layer, and a scan line, a data line, a driving voltage line, and an initialization voltage line connected to the pixel. The pixel may include an organic light emitting diode, a switching transistor connected to the scan line, and a driving transistor to apply a current to the organic light emitting diode. The blocking layer is in an area that overlaps the switching transistor on a plane, and between the switching transistor and the flexible substrate, and receives a voltage through a contact hole that exposes the blocking layer.

Abstract: An atomic layer etching method using a ligand exchange reaction may include a substrate providing step of putting a substrate with a thin film formed thereon into a reaction chamber, a halogenated thin film forming step of forming a halogenated thin film on a surface of the thin film by infusing a halogenated gas into the reaction chamber, and an etching step of etching the halogenated thin film by infusing a ligand without a metal or metal precursor into the reaction chamber with the substrate with the halogenated thin film.

Abstract: An electronic apparatus and a method for controlling the same are provided. The method includes executing an application; acquiring a resource configuration corresponding to the application; first identifying an external electronic apparatus from among a plurality of external electronic apparatuses based on preference information, the first identifying being in response to the resource configuration containing pre-stored information relating to the plurality of external electronic apparatuses; second identifying whether the external electronic apparatus is available; connecting to the external electronic apparatus; and sending a message regarding the application to the external electronic apparatus.

Abstract: A control method of a server is provided, the method including receiving data which a wearable device obtains via near-field communication, from the wearable device, obtaining context information of the wearable device using the received data and generating a UI element corresponding to the context information of the wearable device, and transmitting the context information of the wearable device and the UI element to a user terminal.
