Publication number: 20130171399Abstract: A dielectric adhesive film for an electronic paper display device. A lower electrode to which voltage is applied and an image upper electrode coated with charged particles whose colors are changed depending on the applied voltage are attached to the adhesive film. Thickness of the adhesive film is controlled to be uniform and constant, and a resistance value in the thickness direction of the adhesive film, i.e., a resistance value in the direction where an electric field is formed, is controlled without changing adhesive properties and reliability as the thickness of the adhesive film is controlled. Since loss of the applied voltage is minimized and the charged particles are freely driven, driving performance of the display device is excellent although a high voltage is not applied in driving a flexible display device, such as a flexible LED, an organic electro luminescence (EL) element including an electronic paper, and the like.Type: ApplicationFiled: October 19, 2011Publication date: July 4, 2013Applicant: Toray Advanced Materials Korea Inc.Inventors: Dong Han Kho, Sang Hoon Lee, Chang Ik Hwang, Yeon Soo Kim

Patent number: 8147965Abstract: A film that contains a thermoplastic polyurethane and water-soluble polymer is provided. The film is both elastic and water-sensitive (e.g., water-soluble, water -dispersible, etc.) in that it loses its integrity over time in the presence of water. The dual attributes of elasticity and water-sensitivity may be achieved by reducing the tendency of the thermoplastic polyurethane and water-soluble polymer to form separate phases. Namely, phase separation may cause the elastomer to act as a barrier and limit the ability of the water-soluble polymer to contact water and thereby disperse. To minimize such phase separation, a variety of aspects of the film construction may be selectively controlled, such as the nature of the thermoplastic polyurethane and water-soluble polymer, the relative amount of each component, and so forth. For example, thermoplastic polyurethanes are polar in nature and thus may be generally compatible with water-soluble polymers (e.g., polyvinyl alcohol), which are also polar in nature.Type: GrantFiled: May 14, 2008Date of Patent: April 3, 2012Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Bo Shi, James H.

The holding pad includes a top surface having an uppermost contact surface configured to contact and frictionally cling to the item and a bottom surface having a lowermost contact surface configured to contact and frictionally cling to the vehicle surface. The top and the bottom surfaces are configured to provide a greater frictional engagement between the lowermost contact surface and the vehicle surface than the uppermost contact surface and the item. Protrusions or indentation can be formed in the top and bottom surfaces of the pad.Type: GrantFiled: September 5, 2008Date of Patent: April 12, 2011Assignee: American Covers, Inc.Inventor: Alan J.

Patent number: 7910188Abstract: A frictional holding pad removably attaches handheld items, such as a cell phone, to a surface, such as a dash, to allow storage of handheld items on the surface with the pad to prevent the items from shifting or sliding due to the movement of the support surface. A smoother application side of the pad clings to the handheld item by specific or mechanical adhesion, and a contoured exposed side of the pad clings to the surface by specific or mechanical adhesion. The smoother application side of the pad can have a greater surface area than the contoured exposed side so the pad remains with the handheld item when removed from the surface. Indicia can be formed on the pad. The pad can be translucent or transparent. The pad can include an expanded vinyl material or a polyurethane material.Type: GrantFiled: October 31, 2005Date of Patent: March 22, 2011Assignee: American Covers, Inc.Inventor: Alan J. Wheatley
