Patent number: 7495374Abstract: The present invention provides an electron amplification plate placed between a first substrate and a second substrate of a field emission display device. The electron amplification plate comprises at least two insulating layers for electrical insulation; and at least one conductive electrode layer having plural apertures, wherein the conductive electrode layer is sandwiched between the insulating layers. The surface of the inner wall of the apertures is coated with an electron-amplifying material for multiplying the quantity of electrons as the surface is impacted. The inner wall of each aperture comprises an upper concave wall and a lower concave wall, and the lower concave wall is used for collecting electrons, and the upper concave wall is used for focusing electrons. Thereby, the electron beam emitted from the emitters can be effectively amplified, and color purity of the field emission display device is high.Type: GrantFiled: June 20, 2006Date of Patent: February 24, 2009Assignees: Tatung Company, Industrial Technology Research InstituteInventors: Chi-Tsung Lo, Tzung-Han Yang, Jeng-Maw Chiou, Shy-Wen Lai, Cheng-Feng Lin, Chao-Hsun Lin

Publication number: 20070120459Abstract: A field emission display (FED) device, which includes a top substrate, a bottom substrate, and an intermediate plate set located between the top substrate and the bottom substrate. The top substrate has a phosphor layer and an anode. The bottom substrate has a cathode, and an electron emitter. The intermediate plate set has a metal plate with multiple holes, an insulating layer with multiple holes, and a gate layer. In the FED device, the insulating layer is located between the gate layer and the metal plate for electrical insulation, and the gate layer has a gap from the bottom substrate. Thus, the processing steps prepared for the bottom substrate can be reduced to thereby prevent the electron emitters from damage. The number of electrons bombarding on the phosphor layer is effectively increased to thereby increase the brightness and color contrast on pixels.Type: ApplicationFiled: July 10, 2006Publication date: May 31, 2007Applicants: Tatung Company, Industrial Technology Research InstituteInventors: Tzung-Han Yang, Jeng-Maw Chiou, Shy-Wen Lai, Cheng-Feng Lin, Chao-Hsun Lin

Patent number: 7208866Abstract: A field emission display device includes three parts: a cathode emitter unit, an electron amplification unit, and a faceplate unit. The primary emission of electrons emitted from the cathode emitter unit bombards an electrode layer that includes an electron amplification material in order to generate secondary emissions of electrons. The secondary emissions of electrons bombard a light-emitting layer of the faceplate unit to generate fluorescence. Then, the fluorescence is transmitted through a transparent faceplate for viewing.Type: GrantFiled: June 16, 2004Date of Patent: April 24, 2007Assignee: Industrial Technology Research IndustryInventors: Jeng-Maw Chiou, Jon-Lian Kwo, Kwan-Jon Chang, Shy-Wen Lai, Ai-Kang Li, Hong-Jen Lai, Meiso Yokoyama

Patent number: 6943494Abstract: A field emitting luminous device is disclosed. The device includes a cathode electron emitting unit, an electron amplifying unit, a panel unit, and an electric power supply unit. The primary electrons emitted from the cathode electron emitting unit hit the electron amplifying material on the electrode surface of the electron amplifying unit, generating amplified secondary electrons. The secondary electrons bombard the light-emitting layer of the panel unit, producing fluorescence. The fluorescence penetrates the upper transparent panel and is thus observed by eyes.Type: GrantFiled: March 5, 2003Date of Patent: September 13, 2005Assignee: Industrial Technology Research Institute/Material ResearchInventors: Jeng-Maw Chiou, Jon-Lian Kwo, Kwan-Jon Chang, Shy-Wen Lai, Ai-Kang Li, Hong-Jen Lai
