Abstract: A flexible display device including a substrate, a light emitting layer, a first insulating layer, and a conductive layer. The substrate includes a bent region and a non-bent region. The light emitting layer overlaps the non-bent region. The first insulating layer is disposed on the substrate. The conductive layer is disposed on the first insulating layer. A sidewall of the first insulating layer includes a first tapered surface. The first tapered surface includes at least three curved surface portions continuously arranged with one another.

Abstract: The present invention relates to a catalyst for hydrogenation of an aromatic compound, which is capable of greatly reducing the inactivation of a catalyst by using a support including a magnesium-based spinel structure, and a preparation method therefor.

Abstract: The present disclosure relates to a wireless battery management system which ensures stability when obtaining battery data through wireless communication. The battery management system includes a manager node operating a primary channel and a secondary channel based on wireless communication and obtaining battery data from a monitor node by using the primary channel or the secondary channel and a monitor node connected to a battery module to collect battery data including one or more of a current, a voltage, a temperature, and self-diagnosis data of the battery module, transmit the collected battery data to the manager node through the primary channel, and when the transmission of the battery data through the primary channel fails, transmit the battery data to the manager node through the secondary channel.

Abstract: The present disclosure relates to a wireless battery management system, and more particularly, to a wireless battery management system, a node for wireless communication, and a method of transmitting data, which ensure stability and efficiency when obtaining battery data through wireless communication. A wireless battery management system includes a manager node obtaining battery data from a plurality of monitor nodes by using a first channel and a second channel which are communication channels based on wireless communication, a first monitor node collecting first battery data and transmitting the first battery data to the manager node through the first channel during a first dedicated slot, and a second monitor node collecting second battery data and transmitting the second battery data to the manager node through the second channel during the first dedicated slot.

Abstract: Disclosed are a communication method between a master controller and slave controllers, a slave controller for the communication method, and a battery management system using the communication method and the slave controller, in which the master controller receives safety information about battery cells through a plurality of channels even when each of a plurality of slave controllers includes only one micro controller unit, thereby minimizing the increase in the cost and enhancing the safety of the battery management system. The communication method includes performing bidirectional communication between a master controller and first to Nth (where N is an integer equal to or more than two) slave controllers through a first communication channel, and receiving, by the master controller, an indication signal through a second communication signal via the first to Nth slave controllers.
