Abstract:
A field emission anode plate (1), a field emission light source and a manufacturing method for the light source are provided. The field emission anode plate comprises a transparent ceramic base (10) and an anode conductive layer (11) provided on the surface of the transparent ceramic base which can be excited to produce light by cathode rays. The field emission light source comprises the field emission anode plate, a field emission cathode plate (2) and a supporter (3). The field emission cathode plate comprises a substrate (20) and a cathode conductive layer (21) provided on the surface of the substrate. The anode conductive layer and the cathode conductive layer are arranged opposite to each other, and two ends of the supporter are hermetically connected to the field emission anode plate and the field emission cathode plate respectively, thus the field emission anode plate, the field emission cathode plate and the supporter constitute a vacuum chamber. As the transparency and electron-impact resistance are improved and the corrosion and wear resistance properties are increased, the field emission anode plate is low-cost with luminance uniformity, and the field emission light source also exhibits high luminance intensity, luminance uniformity and a long service life.
Abstract:
The present invention provides devices comprising an assembly of carbon nanotubes, and related methods. In some cases, the carbon nanotubes may have enhanced alignment. Devices of the invention may comprise features and/or components which may enhance the emission of electrons and may lower the operating voltage of the devices. Using methods described herein, carbon nanotube assemblies may be manufactured rapidly, at low cost, and over a large surface area. Such devices may be useful in display applications such as field emission devices, or other applications requiring high image quality, low power consumption, and stability over a wide to temperature range.
Abstract:
An electron emitting element (1) includes a substrate (2), an upper electrode (3), and a fine particle layer (4) sandwiched between the substrate (2) and the upper electrode (3). The fine particle layer (4) includes metal fine particles (6) with high resistance to oxidation, and insulating fine particles (5) larger in size than the metal fine particles (6). The electron emitting element (1) can steadily emit electrons not only in vacuum but also in the atmosphere. Further, the electron emitting element (1) can work without electric discharge so that harmful substances such as ozone, NOx, or the like are scarcely generated. Accordingly, degradation of the electron emitting element (1) due to oxidation does not occur. Therefore, the electron emitting element (1) has a long life and can steadily work continuously for a long period of time even in the atmosphere.
