  • Publication number: 20220059803
    Abstract: The present disclosure is generally related to 3D imaging capable OLED displays. A light field display comprises an array of 3D light field pixels, each of which comprises an array of corrugated OLED pixels, a metasurface layer disposed adjacent to the array of 3D light field pixels, and a plurality of median layers disposed between the metasurface layer and the corrugated OLED pixels. Each of the corrugated OLED pixels comprises primary or non-primary color subpixels, and produces a different view of an image through the median layers to the metasurface to form a 3D image. The corrugated OLED pixels combined with a cavity effect reduce a divergence of emitted light to enable effective beam direction manipulation by the metasurface. The metasurface having a higher refractive index and a smaller filling factor enables the deflection and direction of the emitted light from the corrugated OLED pixels to be well controlled.

  • Patent number: 11176112
    Abstract: An apparatus of adaptive index structures is provided. Four common data attributes, including time, space, keyword, and value, are used. The present invention is a structure adaptively selecting the most efficient combined index by estimating index performance and selectivity rate. The main concept is to set indexes with high selectivity rates at positions having higher priorities for processing query. The intermediate result of query is minimized and the performance is further improved. The present invention uses multiple indexes, where all possible combined-index orders are considered and the best combined index is selected according to different query adaptabilities. As a result, the structure has a high chance of saving query time at a rate of more than 25 times as compared to a structure with indexes of a single attribute sequence. Furthermore, as compared to the traditional relational database PostGIS, the reaction time is also twice faster.
