  • Publication number: 20170257953
    Abstract: Provided is a method for manufacturing an electronic device. The method includes providing a panel to a stage, providing a circuit board, aligning the circuit board so that first pads of the circuit board face a first pad area of the panel and second pads of the circuit board face a second pad area of the panel, and compressing a first portion of the circuit board on which the first pads are arranged to the first pad area of the panel. The aligning of the circuit board occurs via by external contact on one surface of the first portion of the circuit board and one surface of the second portion of the circuit board.

  • Publication number: 20170173932
    Abstract: A lamination device includes a jig configured to accommodate a window having a curved surface; a transfer member configured to allow a film member attached to the window to be spaced from the window; a roller unit configured to press a surface of the transfer member to which the film member is not attached and attaching the film member to the window; a driving unit connected to the roller unit and configured to move the roller unit along the curved surface of the window by rotating with respect to a single rotational center; and a pressing unit connected to the driving unit and the roller unit and configured to press the roller unit.

  • Publication number: 20120135532
    Abstract: The present invention relates to a sensor comprising a resorufin compound having sulfite ion selectivity and a method for detecting sulfite ions using the same. More specifically, the resorufin compound may have outstandingly increased fluorescence intensity by a deprotection reaction that a levulinyl group is cleaved with a sulfite ion to be used as a selective fluorescence sensor of turn-on type, and also represent a chromogenic change to detect sulfite ions by naked eye.

  • Patent number: 7964721
    Abstract: A mercury selective fluorescent chemosensor for detecting mercury ions by a compound represented by formula 1 and a novel fluorescent sensitive compound prepared by introducing two aminopyrene functions as a fluorescent sensitive moiety into a binding site of the compound of formula 1 is used for selectively detecting mercury ions are provided. The mercury selective fluorescent sensitive chemosensor is a switch type chemosensor having ON-OFF-type Hg2+-selective fluorescence quenching behavior and is not affected by other coexistent metal ions. Changes in fluorescence of the compounds of formula 1 were analyzed by ratiometric approach using monomer and excimer emissions of the pyrene fluorophore to selectively signal the concentration of mercury ions. The chemosensor can detect mercury ions in a micromolar unit even in a solution including an excess of water. Accordingly, the mercury selective fluorescent chemosensor for detecting mercury ions can be used effectively in environmental and medical applications.
