  • Patent number: 9887246
    Abstract: An organic light-emitting display panel can improve the color purity and color gamut by reducing optical interference between adjacent pixel areas. A black bank layer is disposed on a planarization layer, such that it is possible to suppress light emitted from an organic emission layer from being reflected via various paths to be scattered to adjacent pixel areas. In addition, the black bank layer comes in contact with a color filter layer via holes formed in the planarization layer to thereby reduce optical interference between adjacent pixel areas. In this manner, the color purity and color gamut of displayed images can be improved, and a display device with excellent image quality can be implemented.

  • Patent number: 9848500
    Abstract: The present invention relates to the field of integrating electronic systems that operate at mm-wave and THz frequencies. A monolithic multichip package, a carrier structure for such a package as well as manufacturing methods for manufacturing such a package and such a carrier structure are proposed to obtain a package that fully shields different functions of the mm-wave/THz system. The package is poured into place by polymerizing photo sensitive monomers. It gradually grows around and above the MMICs (Monolithically Microwave Integrated Circuit) making connection to the MMICs but recessing the high frequency areas of the chip. The proposed approach leads to functional blocks that are electromagnetically completely shielded. These units can be combined and cascaded according to system needs.
