Patent number: 8648521Abstract: A fluorescent display device is disclosed. The fluorescent display device includes an anode plate, aluminum anode wirings arranged on the anode plate, a first light shielding aluminum film arranged on the anode plate, an insulation layer arranged on both the anode wiring and the first light shielding film, a second light shielding graphite film arranged on the insulation layer, an anode electrode arranged on the insulation layer, and an outer light source display formed by removing a portion of the first light shielding film. The outer light source display is illuminated by a LED to display a predetermined pattern. The second light shielding film is formed along a wiring array arranged on the first light shielding film and the wiring so that a gap between the first light shielding film and the wirings is covered with the second light shielding film.Type: GrantFiled: November 1, 2011Date of Patent: February 11, 2014Assignee: Futaba CorporationInventors: Yoshikazu Shibuya, Yoshiaki Washio, Junichi Ogiwara

Patent number: 8319705Abstract: The plasma display device has a display panel having first and second display electrodes and address electrodes, an electrode drive circuit, and a drive control circuit for controlling the electrode drive circuit. The drive control circuit performs a reset drive control, address drive control and sustain drive control in each subfield. The drive control circuit performs an all cell reset drive control which resets all cells in a first subfield out of the plurality of subfields, and an ON cell reset drive control which resets ON cells in a second subfield. At a first temperature T1, an ultimate potential of an slope pulse of the first display electrode is controlled to be a first potential in the ON cell reset drive control, and at a second temperature T2>T1, the ultimate potential is controlled to be a second potential higher than the first potential.Type: GrantFiled: November 25, 2008Date of Patent: November 27, 2012Assignee: Hitachi, Ltd.Inventors: Junichi Kumagai, Katsumi Ito

Patent number: 4658186Abstract: A control apparatus for a fluorescent display tube controls selectively light emission of a plurality of display segments (7a to 7g) provided in a fluorescent display tube (1) so that desired data may be displayed. This apparatus is for example combined with a microwave oven, so as to display the cooking time or the remaining cooking time required for control of the microwave oven or to display the present time of day or other data. Among the display segments (7a to 7g), at least the display segments emitting light relatively less frequently are forced to emit light with predetermined timing, for example, each time cooking operation is ended, whereby irregularities in the frequency for light emission among the display segments (7a to 7g) can be avoided. As a result, no difference is caused in the display brightness in the respective display segments (7a to 7g) and accordingly, clearly visible display can be made.Type: GrantFiled: December 26, 1984Date of Patent: April 14, 1987Assignee: Sanyo Electric Co.Inventor: Atsushi Horinouchi
