Abstract: A display panel for simplifying a manufacturing process and having high energy efficiency using an OLED as a light source and also using RGB, QDs, and an LPR layer capable of improving color reproducibility. In an aspect, an LPR layer is interposed between a color filter layer and a fluorescent substance layer so that light is circulated within the fluorescent substance layer again. Accordingly, there is provided a display panel capable of reducing the amount of light absorbed through the color filler by increasing the light absorption coefficient of the fluorescent substance layer and of maximizing energy efficiency by increasing the intensity of light passing through the color filter.

Abstract: Embodiments disclosed herein provide systems, methods, and computer readable media for generating a consistent deduplicated snapshot of a distributed database using optimistic deduplication. In a particular embodiment, a method provides, for each node of a plurality of nodes in the distributed database, deduplicating data items stored on the node that are owned by the node and generating a summary that describes a file in which the data items are located. The method further provides identifying from the summaries for each of the nodes whether mistakes occurred during deduplication and, upon identifying one or more mistakes, determining one or more corrections for the one or more mistakes. Also, the method provides generating a consistent deduplicated snapshot for the distributed database comprising the deduplicated data items from each node and the one or more corrections.
