Illuminating lamp for a display device, an illuminating device for a display device, and a display device
摘要:
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.
