Patent number: 7847481Abstract: Ribs for defining pixel cells are formed in the shape of a lattice, and sustain electrodes and scan electrodes are disposed near the ribs. The electrodes are spaced apart in each pixel cell, and the sustain electrode and the scan electrode are each cut away between pixel cells arranged in the row direction to provide each pixel cell with individually separated electrodes. In addition, between pixel cells adjacent to each other in the row direction, the sustain electrodes and the scan electrodes are connected to each other by means of a sustain-side bus electrode and a scan-side bus electrode, respectively. This makes it possible to provide a high luminous efficiency. Furthermore, each pixel cell is provided with a wide distance between the electrodes and thereby with a large effective opening portion. Thus, this provides only a small amount of reduction in intensity when the electrodes are spaced apart between the pixel cells arranged in the row direction in order to increase the luminous efficiency.Type: GrantFiled: October 31, 2007Date of Patent: December 7, 2010Assignee: Panasonic CorporationInventors: Yoshio Sano, Nobumitsu Aibara, Yoshiaki Yanai, Toshiyuki Akiyama, Tetsumasa Okamoto, Kazuaki Yanagida, Hirokazu Tateno, Naoto Hirano, Yoshito Tanaka, Tadashi Nakamura, Keiji Nunomura

Patent number: 7023406Abstract: To provide a plasma display device which implements a peak luminance higher than prior art, reduces the power dissipation, improves the smoothness of gradation display, and conducts clear display suitable especially for TV display. By setting a plurality of APL levels according to the average value of the scene brightness, and by shortening a sustaining pulse period and increasing the number of sustaining pulses of each sub-field in APL levels having small APL, the peak luminance is raised. Further, by making the sustaining pulse period long in APL levels having large APL requiring large discharge light emission power, the light emission efficiency is improved and the maximum power dissipation is reduced. The luminance distribution in the scene when the APL level is small is detected. On the basis of that information, setting of the number of sustaining pulses and the sustaining pulse period is changed in the same APL level.Type: GrantFiled: May 9, 2000Date of Patent: April 4, 2006Assignee: NEC CorporationInventors: Keiji Nunomura, Yoshio Sano, Toshiyuki Akiyama, Hachiro Yamada
