摘要： PROBLEM TO BE SOLVED: To provide a discharge tube lighting device for a display device capable of suppressing infrared radiation from a discharge tube to resolve a state that the display device cannot be controlled by a remote controller. SOLUTION: A power controller (3) of the discharge tube lighting device (10) controls an output power of an inverter (4) to a first power during a first period immediately after the start of feeding and controls it to a second power during a second period following the first period and controls it to a third power during a third period following the second period. Infrared emission from the discharge tube is suppressed during the second and third periods following the first period while suppressing the reduction of luminance in an early stage after image display, by repeating a first oscillation period, during which the power controller has a power level higher than an average power in the third period, and a second oscillation period, during which the power controller has a power level lower than an average power in the third period, or a pause period during the second period. The display device having the discharge tube lighting device (10) built therein can be satisfactorily controlled from the second and third periods by a remote controller for channel switching or the like by remote control using an infrared signal.

摘要：本発明は、低温時の光源の点灯不良を防ぐ表示装置用光源駆動装置に関し、温度に応じて出力電圧が変化する温度感知部９４０、温度感知部９４０からの出力電圧に基づいて出力信号のレベルが変化するバッファ部９５０、当該バッファ部９５０からの信号レベルに従って動作状態が変わり、出力信号の周波数が変化する発振部９３１、及び当該発振部９３１からの出力信号に応じてスイッチング動作状態が変化するインバータ９２０を備える。これにより、温度に応じてインバータ９２０に印加される信号の周波数が変化し、光源周囲の温度が設定温度以下である場合には、その信号の周波数を高くしてインバータから出力する電圧を上昇させる。温度が低い始動初期や低温動作時にも、安定した点灯動作が行われ、点灯不良現象を防ぎ、製品の信頼性が向上される効果がある。
