| 20080225028 | Method for Driving a Light Emitting Tube Array - A light emitting tube array drivable in an ADS subfield mode wherein a fluorescent material layer is arranged on an inner wall of each light emitting tube sandwiched between a front substrate and a rear substrate, a discharge gas is airtightly put therein, and a plurality of electrodes formed for generating discharge in the light emitting tube are formed on the front substrate and the rear substrate has a problem that a discharge error is caused so that its cells wherein light emission should be caused do not emit light since the volume of its discharge spaces is extremely larger than that in plasma display panels or since the discharge spaces are partitioned by the light emitting tubes. The inventors have invented a method for driving a light emitting tube array, which has a structure as above described, drivable in an ADS subfield mode, wherein the electric potential of a first pulse in a sustain term and the width thereof, which corresponds to the applying time of the pulse, are appropriately set, thereby preventing the discharge error. | 09-18-2008 |

| 20090179546 | THIN-SHAPED DISPLAY DEVICE - A light emitting portion and an electrode board including electrodes for driving the light emitting portion for light emission are provided as separate members. This allows the light emitting portion to have a smaller thickness, and widens the choices of substrate materials for the electrode board. Therefore, a flexible material can be used for the electrode board, thereby imparting the display device with flexibility. Further, the light emitting portion and the electrode board can be separately produced, so that the degree of freedom is increased in the production of the display device. Therefore, the light emitting portion and the electrode board can be produced in different steps or in different production lines. Further, the light emitting portion, the electrode board and other components can be individually evaluated for quality, thereby reducing the production costs of the display device. | 07-16-2009 |

| 20100231486 | PLASMA ARC TUBE DISPLAY DEVICE - A plasma arc tube display is fabricated by arranging a plurality of arc tubes having fluorescent substance layers on the inside and filled with a discharge gas, joining a front substrate and a rear substrate having electrodes to both surfaces of these arranged arc tubes, and interconnecting a plurality of plasma arc tube modules having frames facing the rear substrate with the flexible front substrate interposed therebetween to connect the electrodes installed on the front substrate to each other. Since the plasma arc tube modules can be folded, the plasma arc tube display can be easily transported even if it has a large-sized screen. | 09-16-2010 |

| 20090273273 | Gas discharge tube, and display device having gas discharge tube arrays - A gas discharge tube includes: a elongated tube within which an electron-emissive film is formed, and which is filled with a discharge gas and sealed; a plurality of pairs of display electrodes disposed on a display side of the elongated tube; a signal electrode disposed on a rear side of the elongated tube; and an elongated support member inserted into the elongated tube and extending in the length direction of the elongated tube. The support member has a curved shape so that a curved inner surface thereof forms a discharge space, has longitudinally extending opposite edges, and has a phosphor layer formed on the inner surface of the support member. The support member further has an end wall at each of longitudinally opposite ends thereof. The end walls and the curved inner surface form an elongated depression in the support member. | 11-05-2009 |
| 20090289934 | Method of driving display device, and display device - A method of driving a display device of a plasma tube array type includes: applying, in a first address period, a scan pulse sequentially to display electrodes, each being one display electrode of each display electrode pair in a first group of display electrode pairs; applying, thereafter, a first supplemental pulse of a same polarity as that of the scan pulse to other display electrodes, each being the other display electrode of each display electrode pair in the first group of display electrode pairs, while applying a second supplemental pulse of a polarity opposite to that of the first supplemental pulse, to address electrodes; and applying, thereafter in the first address period before a second address period, a third supplemental pulse of a polarity opposite to that of the first supplemental pulse to the other display electrode of each display electrode pair in the first group of display electrode pairs. | 11-26-2009 |
