Title:
バックライト源装置
Document Type and Number:
Japanese Patent JP5413401
Kind Code:
B2
Abstract:

To provide a light source device which can be easily manufactured as a surface light source without requiring a high vacuum degree, which has an excellent brightness and luminous efficiency, and which is operable even under a low operation voltage.

The light source device applicable to a backlight module includes a cathode structure 302a, an anode structure 304a, a fluorescent layer 306, a secondary electron generation layer 308, and a low-pressure gas layer 310. The fluorescent layer is arranged between the cathode structure and the anode structure. The low-pressure gas layer is supplied to a gap between the cathode structure and the anode structure. The secondary electron generation layer is arranged on the cathode structure, and generates more secondary electrons to collide with the fluorescent layer, thereby improving the luminous efficiency.
