  • Patent number: 10911662
    Abstract: A portable communication device is provided that is configured to obtain a first image corresponding to an object external to the portable communication device based at least in part on a first focus and a first exposure. The first image, a first graphical user interface (GUI) corresponding to the first focus, and a second GUI are displayed corresponding to the first exposure. The second GUI is moved according to a drag input detected via the touchscreen. The moving includes displaying the second GUI in a moved position. Based at least in part on the drag input, the displayed first image is replaced with a second image using a second exposure determined with respect to the moved position.

  • Publication number: 20090004445
    Abstract: Disclosed is a metallic ink, a method of forming electrodes using the metallic ink, and a substrate using the metallic ink. The metallic ink comprises at least one oxide selected from metal oxide nanoparticles and partially polycondensated metal oxides having a size of 100 nm or less, and metal nanoparticles having a size of 100 nm or less. The oxides and the metal nanoparticles are dispersed as isolated ultrafine particles in solvent. The method comprises patterning the ink using an inkjet printer to form a conductive wire. The substrate is produced through the method. It is thereby possible to conduct patterning using an inkjet printer, and adhesive power to substrates is improved. The metallic ink is useful to produce electrodes of various panels, such as PDPs.
