Patent number: 8044888Abstract: A surface-discharge type PDP includes plural electrode pairs formed of first and second sustain electrodes arranged on a first substrate. Each pair extends along a line direction, and the first and second sustain electrodes are in parallel and adjacent to each other. Plural address electrodes arranged on a second substrate opposing the first substrate via a discharge space, each extending along a row direction, a matrix corresponding to a screen to be displayed is formed with the main electrodes and address electrodes, the address electrodes are orthogonal to the main electrodes, each of the address electrode is divided into, for example two partial address electrodes separated from each other by a border line located between adjacent main electrode pairs, whereby the screen is divided into two partial screens, wherein a first clearance between the partial address electrodes is substantially larger than a second clearance between main electrode pair adjacent across the border line.Type: GrantFiled: February 13, 2009Date of Patent: October 25, 2011Assignee: Hitachi Plasma Patent Licensing Co., Ltd.Inventors: Seiki Kuroki, Nguyen Thanh Nhan

Patent number: 6936966Abstract: A plasma display device having first and second substrates and a discharge gas filled therebetween includes first and second electrodes extending parallel to each other on a first substrate, and first and second discharge electrode parts extending from the first and second electrodes, respectively, so as to oppose each other. A discharge gap of a substantially constant width is formed between one of the first discharge electrode parts and one of the second discharge electrode parts, the ones opposing each other, the discharge gap being defined by first and second edge parts of the ones of the first and second discharge electrode parts, respectively. The first and second edge parts have lengths longer than widths of the ones of the first and second discharge electrode parts, the widths being measured in directions in which the first and second electrodes extend, respectively.Type: GrantFiled: August 15, 2001Date of Patent: August 30, 2005Assignee: Fujitsu Hitachi Plasma Display LimitedInventors: Yoshikazu Kanazawa, Seiki Kuroki
