Abstract: Disclosed are a display substrate. The display substrate includes a drive backplane; a first electrode layer disposed on a side of the drive backplane; a pixel definition layer disposed on a side, distal to the drive backplane, of the first electrode layer; an organic light-emitting layer disposed on a side, distal to the drive backplane, of the pixel definition layer, wherein the organic light-emitting layer comprises: a plurality of organic material layers stacked in a direction perpendicular to and away from the drive backplane, and a portion of the organic material layer disposed inside the partition groove is separated from a portion of the organic material layer disposed outside the partition groove; and a second electrode layer disposed on a side, distal to the drive backplane, of the organic light-emitting layer.

Abstract: Disclosed is an apparatus for charging a battery comprising a first charging device configured to communicate with at least one second charging device, the first charging device and the at least one second charging device configured to charge the battery, and comprising a first controller configured to control the first charging device, wherein the first controller determines the number of the at least one second charging devices by communicating with a second controller.

Abstract: Example apparatus and methods concern creating synthetic backups from existing backups. One example method includes accessing first information that is associated with an existing backup(s). The first information may be computer data that describes data stored on a backup media or appliance. The first information may be referred to as metadata. The existing backup may reside on a backup medium (e.g., tape), on a backup appliance (e.g., disk), or elsewhere. The example method includes instantiating second information (e.g., metadata) associated with a synthetic backup to be created. The second information may be stored on a non-transitory computer-readable medium. The example method also includes selectively manipulating the second information to create the synthetic backup. The manipulating may include copying portions of the first information into the second information. In one embodiment, the synthetic backup is only logically created and thus no data is copied from the existing backup.
