  • Method for forming thin film and method for fabricating organic light-emitting diode (OLED) display using the same
    Patent number: 9614192
    Abstract: A method for forming a thin film for fabricating an organic light-emitting diode (OLED) display is disclosed. In one aspect, the method includes forming a plurality of shadow masks on a substrate. The substrate is then bent to form a predetermined curvature in the substrate. A deposition source is placed at a position having an equal angle with respect to central and peripheral portions of the substrate. The method also includes depositing a deposition material from the deposition source on the substrate and the shadow masks to form a thin film.
    Type: Grant

  • Method of binning pixels in an image sensor and an image sensor for performing the same
    Patent number: 9584742
    Abstract: A method of binning pixels in an image sensor including: dividing a pixel array into a plurality of binning areas, wherein each binning area includes (2n)*(2n) pixels, wherein n is an integer equal to or greater than two; and generating binning pixel data in each of the binning areas, wherein the locations of the binning pixel data of each binning area are evenly distributed within the binning area.

  • IMAGE SENSORS AND IMAGING DEVICES INCLUDING THE SAME
    Publication number: 20150029355
    Abstract: A pixel array includes pixels arranged in a grid, with separate readout paths configured to readout image data from different subsets of the pixels in the array. An image sensor may employ image data from one subset of pixels, which may include fewer pixels than another subset of pixels in the array, to quickly form an image.
