Abstract:
A cathode plate including a substrate, a cathode structure, a gate structure and emission sources is provided. The cathode structure and the gate structure are disposed on the substrate. The emission sources are arranged regularly on the cathode structure. A field emission flat lamp including said cathode plate, an anode plate and a sealant is provided. The sealant is disposed between and seals the cathode plate and the anode plate. Since the volume of each emission source is small, the bubbles resided inside the emission sources can be reduced, such that the qualities of the field emission flat lamp and the cathode plate thereof can be improved.
Abstract:
An improved shield of belted wheel of a compound machine comprises mainly a slide hole disposed at an appropriate location of upper portion thereof and a slide cover positioned correspondingly to the slide hole. The slide cover is characterized in that it comprises two rails located at lateral sides of bottom surface thereof to permit the slide cover to move along the confines of the slide hole in such a way that there is a sufficient open space in the slide hole to allow the shield to be lifted through the main shaft. The shield can be therefore opened up and closed with ease and speed.
Abstract:
A triode field emission display is provided. It utilizes the electrical characteristics that an edge structure may raise the electric field intensity to expose an edge of a cathode plate through an opening of a gate layer, thereby forming the edge structure at an emitter to raise the electric field intensity. Therefore, reduction of driving voltage is achieved.
Abstract:
A cathode plate including a substrate, a plurality of cathode structures, a plurality of gate structures, and an emission layer is provided. The cathode structures and the gate structures are strip-shaped and disposed on the substrate. The cathode structures and the gate structures are parallel interlaced with one another. Each of the cathode structures has at least one groove, and the emission layer is disposed in the grooves. A field emission flat lamp including the above cathode plate, an anode plate, and a sealant is provided. The sealant is disposed between and seals the cathode plate and the anode plate. With the grooves on the cathode structures, the emission layer is positioned precisely to improve the light uniformity of the field emission flat lamp.
Abstract:
This invention provides a method for enhancing the luminance and uniformity of a flag panel light source and the light source thereof. It provides a patterned reflective structure to reflect or deflect the light back onto the display area and lighten the area which used to be blocked by spacers. The patterned reflective structure may be designed in several places, such as between an end surface of a spacer and the inner surface of an anode substrate, or on the inner surface of the edges of the side-frame between the anode plate and the cathode plate by further coating a reflective material, or on the side-frames surrounding the panel by further coating a reflective material, etc. With such a patterned reflective structure, this invention enhances the luminance and uniformity of a flat panel light source. The present invention can be applied to field emission displays.

A double-sided luminous compound substrate is disclosed. The double-sided luminous compound substrate comprises: a first transparent substrate, having a plurality of first conductors parallel disposed on a surface thereof, and a plurality of parallel-disposed second conductors overlapping the first conductors, each first conductor having a plurality of emitters equidistantly disposed thereon and electrically connected thereto; a second transparent substrate, disposed parallel to and opposite to the first transparent substrate, further comprising a fluorescence layer formed on the side facing the first transparent substrate; and a plurality of spacers, disposed between the first and second transparent substrates.
Abstract:
An apparatus for generating a planar light source and method for driving the same is provided. The apparatus for generating a planar light source comprises an emitting layer disposed not only on a cathode electrode, but also on a gate electrode as well. Accordingly, by applying an AC voltage to the apparatus, a duty cycle of the AC voltage can reach 100% so as to enhance the brightness to the extent that the apparatus is applied a DC voltage.
