Abstract:
A backlight unit is provided to supply high voltage to an anode electrode and to secure the desired luminance. The backlight unit comprises the base substrate(110), the first electrode(120), the electronic emitting layer(150), the second electrode support portion(140), the second electrode(130), the fluorescent material layer(70) and the third electrode(80). The first electrode is arranged as line-shape on the base substrate. The electron emitting layer is located on the first electrode. The second electrode supporting unit is located on the base substrate. The fluorescent substance layer is arranged in order to be faced with the electronic emitting layer. The electrons of the electronic emitting layer are accelerated by the third electrode.
Abstract:
An electron emission device and an electron emission display device using the same are provided to suppress the generation of a sub-electron beam for inducing secondary emission by optimizing a ratio of a width of an electron emission part to a width of an aperture of a gate electrode. A plurality of first electrodes(14) are formed on a substrate(10). A plurality of electron emission parts(20) are electrically connected with the first electrodes. A plurality of second electrodes(18) are isolated from the first electrodes. A plurality of apertures are formed at intersections between the first and second electrodes in order to open the electron emission parts. A plurality of third electrodes(22) are isolated from the second electrodes in order to form apertures connected to the apertures of the second electrodes. The electron emission unit and the second electrodes satisfy simultaneously the following conditions D2/D1 0.579 and D2 1mum where D1 is a width of the aperture of the second electrode and D2 is a width of the electron emission part.
Abstract in simplified Chinese:本发明提供一种能以简单之步骤对某种程度之面积以一次进行加工之冷阴极电子源的制造方法。本发明之冷阴极电子源之制造方法系在基板1上重叠阴极电极2、绝缘层4及闸极电极5,以溶剂溶解不会相溶之聚合物A、B并使其被覆在闸极电极之表面。使溶剂蒸发而将聚合物A以微粒子状析出在聚合物B中并予以固定化,再以显影液去除聚合物A而形成蚀刻孔洞9,并进行蚀刻而在闸极电极形成孔洞6。并且,从孔洞6进行蚀刻而在绝缘层亦形成孔洞,在孔洞内形成射极而作成冷阴极电子源10。
