The emitter layer and the gate electrode layer are disposed on a common plane of the cathode substrate and separated with each other to form an interval. The dielectric layer is formed in the interval between the emitter layer and the gate electrode layer, but not connected to the interval between the emitter layer and the gate electrode layer, so as to change the electric field distribution of the emitter layer and the gate electrode layer.
Abstract:
A liquid crystal display using dynamic emission device as backlight source includes a field emission device and a liquid crystal panel. The field emission device is divided into plural field emission sections formed as a chessboard. The surface of the field emission device is attached to the liquid crystal panel. Wherein, each field emission section is corresponded to each image-displaying section on the liquid crystal panel. According to the lightness variation of each image-displaying section, each field emission section dynamically compensates the lightness of each image-displaying section. Thereby, the objective of enhancing the dynamic range of the liquid crystal display is achieved.
Abstract:
A vacuuming sintering method for forming a carbon nanotube of a field display is disclosed. A cathode is attached to an anode, and the assembly of the cathode and anode is disposed on a heating element of a vacuum sintering furnace with cathode adjacent to the heating element. Each of the cathode and anode has at least one electrode lead connected to an external voltage source. The internal pressure of the vacuum sintering furnace is reduced, the heating element is activated, and a voltage is provided across the cathode and the anode, such that an electric field is generated between the cathode and the anode. The voltage is switched off after the electric field is formed and continuing heating for a predetermined period of time. The heating is terminated and the assembly of the cathode and anode is removed from the vacuum sintering furnace, such that the carbon nanotube is formed parallel to the electric field and perpendicular to the cathode, or one end of the carbon nanotube is inclined towards the anode to advantage electron generation therefrom.
Abstract:
A method of fabricating a tetraode field-emission display. A mesh is disposed between an anode plate and a cathode plate. The mesh has a gate layer and a converging electrode layer separated by an insulation layer to form a sandwich structure. The mesh has a plurality of apertures in correspondence with each set of anode and cathode. The converging electrode layer is facing the anode plate, such that the divergent range of an electron beam emitted by an electron emission source can be restricted. Thereby, the electron beam can impinge the corresponding anode more precisely.

Abstract:
A vacuum glass structure comprising two glass substrates maintained at an substantially constant interval by a glass frit paste sealingly adhering to the peripheries thereof, forming a hermetically sealed vacuum room. A receiving gap is formed at the periphery of the glass substrate. The internal surface of the glass structure further includes an air chamber and a glass tube groove for receiving a pumping tube. The pumping tube can be placed inside the receiving gap with the internal end of the pumping tube extending from the receiving gap through the glass tube groove into the air chamber. The external end of the pumping tube constitutes a hermetic seal retained within the geometric boundary of the receiving gap. The air chamber structure may improve air transferring efficiency and prevents problems such as blockage in the pumping tube, thus enabling an increase in production yield.
Abstract:
A field emission display includes a cathode plate and an anode plate. The anode plate is provided with an anode unit thereon. The cathode plate is provided on a cathode substrate with two electrodes that are located in a common plane and separated from each other to correspond to a common anode unit. Cathode electron-emitters are provided on the two electrodes respectively. A reverse voltage is applied to the two electrodes alternately, causing the alternation of the positive and negative voltages between the two electrodes. As a result, the two electrodes form a gate and an emitter alternately based on the applied positive or negative voltage. Therefore, the cathode electron-emitter provided on the coplanar electrodes will generate electron beams alternately.
