  • Patent number: 9269923
    Abstract: A method and apparatus for depositing an inorganic layer onto a substrate is described. The inorganic layer may be part of an encapsulating film utilized in various display applications. The encapsulating film includes one or more inorganic layers as barrier layers to improve water-barrier performance. An oxygen containing gas, such as nitrous oxide, is introduced during the deposition of the inorganic layer. As a result, the inorganic layer is lower in stress and may obtain a water vapor transmission rate (WVTR) of less than 100 mg/m2-day.

  • Patent number: 9261990
    Abstract: A hybrid touch screen device applied to an electric device. The hybrid touch screen device preferably includes a touch panel, a pen touch panel, a display panel, and at least one processor. The touch panel detects an input event by a direct touch. The pen touch panel detects a touch pen input and an input event from an entry into a predetermined detection distance before a touch. The display panel displays a screen according to the touch panel, the pen touch panel, and a user operation. The processor also performs control to execute a relevant function according to an input event inputted to the touch panel and the pen touch panel. The processor also performs control so that an input event of the touch pen and an input event of the touch panel are detected independently of each other.

  • Patent number: 8877301
    Abstract: An asymmetrically grounded susceptor used in a plasma processing chamber for chemical vapor deposition onto large rectangular panels supported on and grounded by the susceptor. A plurality of grounding straps are connected between the periphery of the susceptor to the grounded vacuum chamber to shorten the grounding paths for RF electrons. Flexible straps allow the susceptor to vertically move. The straps provide a conductance to ground which is asymmetric around the periphery. The straps may be evenly spaced but have different thicknesses or different shapes or be removed from available grounding point and hence provide different RF conductances. The asymmetry is selected to improve the deposition uniformity and other qualities of the PECVD deposited film.
