Patent number: 7050020Abstract: A 3D image/2D image switching display apparatus is provided with a liquid crystal display unit and first and second lenticular lenses. To display a 3D image, the first lenticular lens is arranged in such a way that the optical axis of the first lenticular lens coincides with the optical axis of the second lenticular lens so that pixels for a left eye display an image for a left eye and pixels for a right eye display an image for a right eye. To display a 2D image, the first lenticular lens is arranged in such a way that the optical axis of the first lenticular lens is shifted from the optical axis of the second lenticular lens by half a lens pitch so that the pixels for the left eye and the pixels for the right eye display the same image independently.Type: GrantFiled: August 25, 2003Date of Patent: May 23, 2006Assignee: NEC CorporationInventors: Shin-ichi Uehara, Nobuaki Takanashi, Hiroshi Hayama

Publication number: 20050206600Abstract: Provided is a structure which is capable of narrowing a semiconductor chip in width and a display device which is narrowed in frame by using the same. In the structure of a semiconductor chip provided such that the semiconductor chip is mounted on a glass substrate and a plurality of power lines (a first wiring and a second wiring) of the semiconductor chip are extended in a continuous direction so as to form, the structure of the semiconductor chip comprises the power lines with different electric potentials, which is formed by overlapping. Rather than making a capacity at the overlapped area of wirings and forming the wiring alone, a wiring which is narrowed in width may be achieved.Type: ApplicationFiled: March 7, 2005Publication date: September 22, 2005Inventors: Daigo Miyasaka, Hiroshi Hayama
