摘要:
A cold cathode lighting device is a fluorescent tube replacement and has a transparent tube, a cold cathode formed as a wire or rod with an electron emissive surface and passing through a center of the transparent tube. An extraction grid is formed around and spaced apart from the cold cathode and has an external diameter smaller than an inner diameter of the transparent tube. A phosphor material and a conductive material form an anode on an inner surface of the transparent tube. A vacuum is maintained within the transparent tube and a power conversion circuit in an end unit converts electrical power into a first potential applied to the cold cathode, a second potential applied to the extraction grid and a third potential applied to the anode. Electrons emitted from the cold cathode accelerate towards the anode and light is emitted from the fluorescent tube replacement light emitting device.

摘要:
A light emission device, which can enhance degree of vacuum in a vacuum vessel by increasing an adsorption efficiency of a getter, and a display device using the light emission device for a light source are provided. The light emission device (101, 102, 103, 104, 105) includes a vacuum vessel (18) having first and second substrates (12, 14) facing each other with a predetermined distance therebetween, and a scaling member (16) disposed between the first and second substrates (12, 14) and enclosing an inner space formed between the first and the second substrates (12, 14). An electron emission unit (20, 201, 202) having a plurality of electron emission regions (24, 90) is located on one side of the first substrate (12) facing the inner space. A light emission unit (22, 221) having an anode electrode (32) and a phosphor layer (34, 341) is located on one side of the second substrate (14) facing the inner space. A getter layer (38, 381, 382) is disposed on an inner surface of the sealing member (16) that faces an inner space of the vacuum vessel (18).
