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:
A field emission backlight unit comprises a substrate, first electrodes and second electrodes, a fluorescent lighting panel and an anode plate. The first electrodes are disposed on the substrate. The second electrodes are interlaced with the first electrodes and disposed on the substrate. The second electrodes receive a clock signal sequentially according to a first period. The fluorescent lighting panel is disposed at the opposite side of the substrate. The anode plate is disposed at the opposite side of the substrate. When there is a specific voltage between the first electrodes and the second electrodes to generate electrons, the anode plate pulls electrons to hit the fluorescent lighting panel to emit light.
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:
A quadrode field emission display is provided, where a low driving voltage is reached by an edge structure, and display in the dark is achieved by adding a sub-gate electrode. With respect to the electrical characteristics that an edge structure may raise the electric field intensity, an edge of a cathode plate through an opening of a gate layer is exposed, thereby forming the edge structure at an emitter to raise the electric field. It also reduces the driving voltage substantially. Therefore, the display in the dark is achieved by adjusting the voltage without changing the structure.
Abstract:
A method for prolonging the life span of a planar light source generating apparatus is provided. The planar light source generating apparatus forms an emitting layer not only on a plurality of cathodes but on a plurality of gates as well. Moreover, an anode of the planar light source generating apparatus is electrically connected to a current sensor for reading out a maximum current density when the planar light source generating apparatus operates. To operate the planar light source generating apparatus, a DC square voltage is applied to the cathodes (or gates) while the gates (or the cathodes) are electrically connected to a ground. Once the current density detected by the current sensor drops to a definite ratio of the maximum value, the external voltage supplying the aforementioned cathodes and the gates are switched. Thus, the life span of the planar light source generating apparatus is prolonged.

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:
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.
