摘要:
A method for manufacturing a cathode assembly of a field emission display, includes the steps of: providing a substrate (110) with a cathode (113) formed thereon; forming an electrically insulating layer (120), a gate electrode layer (130) and a photoresist layer (140) on a cathode in series; defining at least one opening (141) in the photoresist layer using a photolithographic process; etching the gate electrode layer through the at least one opening so as to form at least one gate electrode opening (131) in the gate electrode layer; etching the electrically insulating layer to define at least one cavity (121) in the electrically insulating layer; pressing the photoresist layer in a manner such that a size of the at least one opening is reduced; depositing a catalyst layer (170) in the at least one cavity through the at least one opening; and growing carbon nanotubes (180) on the catalyst layer.

An exemplary carbon nanotube field emission device includes a cathode, at least one carbon nanotube emitter formed on the cathode, an anode facing the cathode, at least one gate electrode arranged between the cathode and the anode, at least one spacer arranged between the gate electrode and the cathode, and an electrically insulating layer formed on an underside surface of the gate electrode. The at least one spacer defines at least one cavity therein with the at least one carbon nanotube emitter being received in the at least one cavity. The electrically insulating layer is configured for preventing the underside surface of the gate electrode from being exposed to the cavity. A method for manufacturing a carbon nanotube field emission device is included.

A field-emission-based flat light source includes a light-permeable substrate, a transparent electrically conductive cathode, an electron emitter, an anode layer, a light-reflecting layer, a fluorescent layer. The light-permeable substrate has a surface. The transparent electrically conductive cathode layer is disposed on the surface of the light-permeable substrate. The electron emitter is disposed on the transparent electrically conductive cathode layer. The anode layer faces and is spaced from the transparent electrically conductive cathode layer. A vacuum chamber is formed between the anode layer and the transparent electrically conductive cathode layer. The light-reflecting layer is formed on the anode layer, and faces the transparent electrically conductive cathode layer. The fluorescent layer is formed on the light-reflecting layer.

A field-emission-based flat light source includes the following: a light-permeable substrate; a plurality of line-shaped cathodes; an anode; a light-reflecting layer; and a fluorescent layer. The light-permeable substrate has a surface, and the line-shaped cathodes, with a plurality of carbon nanotubes formed and/or deposited thereon, are located on the surface of the light-permeable substrate. The anode faces the cathodes and is spaced from the cathodes to form a vacuum chamber. The light-reflecting layer is formed on the anode and faces the cathode. The fluorescent layer is formed on the light-reflecting layer.
