  • Patent number: 10976614
    Abstract: A method of manufacturing a stretched display panel includes: cutting the TFT substrate to a desired size; cutting the color filter substrate; forming an open-circuit line for open-circuiting a portion defined between a horizontal pixel line that is located at an end of the TFT substrate and another horizontal pixel line adjacent thereto in order to prevent electrical noise due to the horizontal pixel lines being introduced into the end of the TFT substrate exposed from the pixel exposure portion; and forming a reinforcement seal for covering the pixel exposure portion using a reinforcement material in order to prevent occurrence of short circuit due to introduction of foreign matter into a gap defined between the horizontal pixel line and the other horizontal pixel line and at the same time to increase rigidity of the pixel exposure portion.

  • Publication number: 20090011308
    Abstract: A common method of preparing a gas diffusion layer for a fuel cell has problems in that a microporous layer is impregnated into a substrate, thereby lowering the porosity of the substrate, and cracks are created on a surface of a gas diffusion layer prepared using the method. Provided is a method of reproducibly preparing a gas diffusion layer with a uniform thickness and no cracks based on the principle of a primer coating method, wherein a first microporous layer is hardly impregnated into a substrate and uniformly covers a surface of the substrate, and at least one microporous layer is further coated on the first microporous layer. Provided is also a fuel cell showing improved performance by enhancing utilization of a catalyst layer and guaranteeing a uniform diffusion of fuel and an efficient discharge of a product.
