  • Publication number: 20170351404
    Abstract: The present disclosure provides a method and apparatus for moving an icon, an apparatus and a non-volatile computer storage medium. In embodiments of the present disclosure, an icon to be moved is determined, then the user's first operation gesture for the terminal is obtained, and an operation interface is determined according to the first operation gesture so that the icon can be moved into the operation interface. Since the icon can be directly moved into the operation interface according to the user's first operation gesture for the terminal, icon movement can be achieved without completely depending on the user's operation for the icon and without requiring the user to use the terminal to perform cross-screen operation with a larger operation amplitude.

  • Publication number: 20170192559
    Abstract: The present invention provides an OGS touch screen, a manufacturing method thereof and a display device. The OGS touch screen comprises a base substrate and a metal bridge provided on the base substrate, wherein at least a region, which corresponds to the metal bridge, of a surface of the base substrate facing the metal bridge is uneven. In the OGS touch screen provided by the present invention, by making at least the region of the surface of the base substrate corresponding to the metal bridge uneven, incident light from a side of the base substrate without the metal bridge can be reflected diffusely at least at the region of the base substrate corresponding to the metal bridge, so that the vanishing effect of the metal bridge is enhanced and the visibility of the metal bridge is reduced.
