Abstract: Embodiments disclose a display device including a substrate including a display area, a light-transmitting area, a non-display area adjacent to the light-transmitting area, and a first opening that is disposed at a position corresponding to the light-transmitting area. The display device includes a circuit portion and a light-emitting element portion that are disposed in the display area. The display device includes a conductive pattern disposed in the non-display area. The display device includes an etch stop pattern disposed in the non-display area. The display device includes a first coating layer disposed in the first opening and having conductivity. The conductive pattern is electrically connected to the first coating layer. The substrate includes a glass substrate.

Abstract: A method of a terminal may comprise: receiving, from a CU of a base station, configuration information of one or more candidate cells and configuration information for measurement; performing L1 measurement on the candidate cells based on the configuration information for measurement; acquiring uplink synchronization for the candidate cells by performing an uplink synchronization management procedure for the candidate cells based on the configuration information of the candidate cells; reporting a result of the L1 measurement to a DU of the base station; receiving, from the DU of the base station, information on a target cell, being the target cell to switch among the candidate cells, based on the result of the L1 measurement; and applying the uplink synchronization acquired through the uplink synchronization management procedure to the target cell.

Abstract: A method of a terminal may comprise: receiving a first message including state information of a base station from the base station; identifying preliminary inactive state information included in the first message when the state information of the base station indicates a preliminary inactive state; and performing a cell selection based on the preliminary inactive state information.

Abstract: A disclosed display device capable of detecting bonding defects includes: a display panel having an active area used to display images and a pad area in which pads are formed; driver IC (Integrated Circuit) chip mounted on a pad region of the display panel; a flexible printed circuit board bonded to the pad region of the display panel; and a bonding resistance detection circuit disposed in the driver IC chip. The display panel includes: first and second bonding portions formed in a mounting region of the driver IC chip within the pad area of the display panel; and third and fourth bonding portions formed in a bonding region of the flexible printed circuit board within the pad area of the display panel. The first through fourth bonding portions are electrically connected to one another, and the first and second bonding portions are connected to the bonding resistance detection circuit.

Abstract: A bonding-defect-detectable display device is disclosed which includes: a display panel defined into an active area used to display images and a pad area in which pads is formed; driver IC (Integrated Circuit) chip loaded on a pad region of the display panel; a flexible printed circuit board mounted to the pad region of the display panel; and a bonding resistance detection unit disposed into the driver IC chip. The display panel includes: first and second bonding portions formed in an occupation region of the driver IC chip within the pad area of the display panel; and third and fourth bonding portions formed in an occupation region of the flexible printed circuit board with the pad area of the display panel.
