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 |
