Publication number: 20130063684Abstract: When a user operates a touch sensor panel having an LCD device outdoors or in a bright environment, light reflecting off the device can create glare. In order to reduce glare, a user can view the device through polarized filters such as polarized sunglasses. Doing so can reduce the visibility of the image displayed on the LCD. A quarter-wave retardation film can be added to the touch sensor panel's LCD device to mitigate these effects by producing circularly polarized light. However, adding a separate quarter-wave retardation film can increase the thickness and cost of manufacturing the touch sensor panel. Embodiments of the present disclosure are directed to a touch sensor panel constructed from a base film having quarter-wave retardation properties that can produce circularly polarized light. Because the base film has the desired optical properties, a separate quarter-wave retardation film may not be needed.Type: ApplicationFiled: September 12, 2011Publication date: March 14, 2013Inventors: Cheng Chen, Siddharth Mohapatra, Lili Huang, John Z.

Patent number: 8372668Abstract: In a manufacturing method of a light-emitting device, a separation layer is formed over a substrate; a semiconductor circuit element layer and first electrodes are formed over the separation layer; a partition wall overlapping with end portions of the first electrodes is formed; and organic material layers are formed over the first electrodes. Organic material layers emitting light of the same color are arranged adjacent to each other in a line and extend in a first direction. A second electrode is formed using a material having high adhesiveness to the partition wall over the organic material layers to be in contact with the partition wall. A stack structure including the semiconductor circuit element layer, the first electrodes, the partition wall, the organic material layers, and the second electrode is separated from the substrate using the separation layer in a second direction perpendicular to the first direction.Type: GrantFiled: March 23, 2010Date of Patent: February 12, 2013Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Kaoru Hatano, Takaaki Nagata, Takuya Tsurume
