20100066916 | DISCHARGE TUBE SUPPORTING STRUCTURE, SUPPORTING MEMBER, DISCHARGE TUBE, FERRULE, LIGHTING DEVICE, DISPLAY DEVICE AND TELEVISION RECEIVER - Discharge tubes, each of which includes a glass tube and a ferrule that has a substantially cylindrical shape and is fitted to each end portion of the glass tube, are supported by a plurality of pairs of relay connectors (or supporting members) provided on the front side of a chassis having substantially a plate-shaped configuration. When a discharge tube is supported by relay connectors, stoppers provided on the relay connectors lock the ferrules so that axial movement of the discharge tube relative to the relay connectors is restricted. | 03-18-2010 |
20100084977 | COLD CATHODE TUBE LAMP - Disclosed is a cold cathode lamp composed of discharge tube having a glass tube and an internal electrode, and a ballast capacitor integrally mounted to the discharge tube. The ballast capacitor is composed of a first electrode formed on the outer surface of the discharge tube, a dielectric layer covering the first electrode, and a second electrode formed on the dielectric layer. The internal electrode and the first electrode are electrically connected with each other. At least one of the internal electrode and the first electrode has a portion exposed to the outside. The capacitance of the ballast capacitor can be measured by connecting the exposed portion and the second electrode to a measuring device. Consequently, variations in capacitance of the ballast capacitor, which cause variations in luminance of the cold cathode lamp, can be easily examined. | 04-08-2010 |

When a discharge tube is supported by relay connectors, stoppers provided on the relay connectors lock the ferrules so that axial movement of the discharge tube relative to the relay connectors is restricted. | 04-22-2010 |
20100134045 | COLD CATHODE TUBE LIGHTING DEVICE - A cold cathode tube lighting device prevents emission-position-dependent unevenness from occurring in the brightness of light emitted from the cold cathode tube lighting device and includes a plurality of discharge tubes connected in parallel; ballast capacitors each integrally attached to a respective one the plurality of discharge tubes; power supplies arranged to that supply power to the plurality of discharge tubes; and a voltage detection unit connected to the plurality of discharge tubes to detect voltages between pairs of internal electrodes of the plurality of discharge tubes. The power supply to the plurality of discharge tubes is controlled according to the voltages detected by the voltage detection unit. | 06-03-2010 |
20100141846 | DISCHARGE TUBE SUPPORTING STRUCTURE, SUPPORTING MEMBER, DISCHARGE TUBE, FERRULE, LIGHTING DEVICE, DISPLAY DEVICE AND TELEVISION RECEIVER - Discharge tubes, each of which includes a glass tube and a ferrule that has a substantially cylindrical shape and is fitted to each end portion of the glass tube, are supported by a plurality of pairs of relay connectors (or supporting members) provided on the front side of a chassis having substantially a plate-shaped configuration.

20090033234 | ILLUMINATING LAMP FOR A DISPLAY DEVICE, AN ILLUMINATING DEVICE FOR A DISPLAY DEVICE, AND A DISPLAY DEVICE - An illuminating lamp for a display device is capable of minimizing a luminance difference between a high-voltage driving side and a low-voltage driving side. The illuminating lamp is arranged behind a display panel via optical sheets and driven in a high-voltage driving method. The illuminating lamp includes discharge lamps connected in series, wherein gas pressures of the discharge lamps at a high-voltage driving side are set to be higher than those of the discharge lamps at a low-voltage driving side. | 02-05-2009 |
20090201666 | BACKLIGHT MODULE, BACKLIGHT MODULE MANUFACTURING METHOD, LIGHTING DEVICE, DISPLAY DEVICE AND TELEVISION RECEIVER - In a backlight module, when relay connectors exposed to a back side of a chassis are engaged with the connector portions of a lighting jig, the power from the power supply source of the lighting jig is supplied to discharge tubes via the connector portions and the relay connectors. Thereby, the discharge tubes can be lighted, even if a power board is not connected to the relay connectors. At the time, the lighting jig is arranged to face the back surface of the chassis, and therefore optical sheets can be mounted to the chassis from the front side. | 08-13-2009 |
20090209126 | RELAY CONNECTOR, MOUNTING STRUCTURE OF RELAY CONNECTOR AND CHASSIS, AND MOUNTING STRUCTURE OF RELAY CONNECTOR AND DISCHARGE TUBE - Relay connectors are arranged to supply power from power boards arranged on the back side of a chassis having a substantially plate-shaped configuration to discharge tubes arranged on the front side of the chassis. Each relay connector includes a holder having an insulation property and to be mounted to the chassis, and further includes a relay terminal mounted to the holder and capable of electrical connection to the discharge tube and the power board. The relay terminal is immune to direct contact with the chassis. This enables the use of a metallic chassis. | 08-20-2009 |
