  • Publication number: 20170194448
    Abstract: Embodiments of the present disclosure provide an array substrate and a manufacturing method thereof, and a display device. The array substrate includes a base substrate, a first electrode pattern, a second electrode pattern, and an active layer pattern disposed on the base substrate, a first electrode protection pattern coating the first electrode pattern, and a second electrode protection pattern coating the second electrode pattern. The active layer pattern is disposed between the first electrode pattern and the second electrode pattern. The first electrode protection pattern and the second electrode protection pattern are connected to two sides of the active layer pattern, respectively. The problem that, the active layer pattern cannot be connected to the first electrode pattern and the second electrode pattern due to the surface oxidation, when the first electrode pattern and the second electrode pattern adopt material with low resistance characteristic, is avoided, thus increasing the product yield.

  • Patent number: 9684959
    Abstract: A method is proposed for automatically locating the optic disc or the optic cup in an image of the rear of an eye. A portion of the image containing the optic disc or optic cup is divided into sub-regions using a clustering algorithm. Biologically inspired features, and optionally other features, are obtained for each of the sub-regions. An adaptive model uses the features to generate data indicative of whether each sub-region is within or outside the optic disc or optic cup. The result is then smoothed, to form an estimate of the position of the optic disc or optic cup.

  • Patent number: 9679379
    Abstract: A method is presented to obtain, from a retinal image, data characterizing the optic cup, such as data indicating the location and/or size of the optic cup in relation to the optic disc. A disc region of the retinal image of an eye, is expressed as a weighted sum of a plurality of pre-existing “reference” retinal images in a library, with the weights being chosen to minimize a cost function. The data characterizing the cup of the eye is obtained from cup data associated with the pre-existing disc images and the corresponding weights. The cost function includes (i) a construction error term indicating a difference between the disc region of the retinal image and a weighted sum of the reference retinal images, and (ii) a cost term, which may be generated using a weighted sum over the reference retinal images of a difference between the reference retinal images and the disc region of the retinal image.
