Patent number: 8871298Abstract: A method for preparing a flexible film substrate with a low glass transition temperature can be used in the production of an article that retains dimensions and improves the surface smoothness after high temperature processing. The invention, for example, would enable low temperature films such as PET and PEN to be dimensionally stable and ultra flat at conditions commonly used in electronic processing which can typically exceed 200° C. More specifically, the methods enable the use of e.g. barrier films based on PET or PEN in OLED/PLED manufacturing.Type: GrantFiled: February 7, 2007Date of Patent: October 28, 2014Assignee: 3M Innovative Properties CompanyInventors: Mark A. Roehrig, Yufeng Liu, Robert W. Peterson

Patent number: 8824066Abstract: This invention provides an injection-molded plastic optical lens comprising: an optical effective region and a peripheral region that are concentrically formed. An outer edge of the peripheral region comprises an indentation section, and an accommodation space surrounded by the indentation section of the outer edge of the peripheral region and an extending line extending from the non-indented section of the outer edge of the peripheral region. The accommodation space confines a flash generated during the injection-molding process of the plastic optical lens so that the assembling of the present plastic optical lens will not be affected. The present invention employs a mold having an air duct connected to an indentation configuration of the mold. The indentation section of the plastic optical lens is formed through a mold replication of the indentation configuration.Type: GrantFiled: October 26, 2012Date of Patent: September 2, 2014Assignee: Largan Precision Co., Ltd.Inventor: Wei-Hung Weng
