Abstract: Apparatus and method are provided for a package structure that enables mounting of a field-emitting cathode into an electron gun. A non-conducting substrate has the cathode attached and the cathode is electrically connected to a pin through the substrate. Other pins are electrically connected to electrodes integral with the cathode. Three cathodes may be mounted on a die flag region to form an electron gun suitable for color CRTs. Accurate alignment of an emitter array to the apertures in the electron gun and other electrodes such as a focusing lens is achieved. The single package design may be used for many gun sizes. Assembly and attachment of the emitter array to the electron gun during construction of the gun can lower cost of construction.

Abstract: A vacuum envelope that can improve the vacuum degree in a field emission device is provided. The vacuum envelope includes the cathode side substrate 2 on which field emission elements are formed and the anode substrate 1 spaced by a predetermined distance in the electron emission direction. At least two openings are formed before sealing the vacuum envelope. The remaining gas is ousted from the vacuum envelope by introducing a high temperature gas inside the vacuum envelope for a predetermined period of time. Thereafter, one of the openings is sealed while the envelope is being evacuated to a vacuum state through the remaining openings.

Abstract: A field emission display having an n-channel high voltage thin film transistor is disclosed. According to the present invention, a signal for driving pixels controls by the nHVTFT attached with each pixel, therefore, the signal voltage of row and column drivers is exceedingly decreased. As a result, it is possible to implement a field emission display capable of providing a high quality picture in a low consumption power, a low driving voltage and inexpensive to manufacture, and preventing a line cross talk using the nHVTFT. By using a cylindrical resistive body underlying a cone-shaped emitter tip, the present invention is to provide a field emission display having an excellent contollability and stability of the emission current, and a dynamic driving capability.

Abstract: A cold cathode structure, useful for field emission displays, is disclosed. A thin resistive silicon film is disposed on a glass substrate; conductive emitter tips are disposed on top thereof. An alloy of amorphous silicon and amorphous carbon is used for the emitter tips. The proportion of the carbon in the alloy increases, gradually or abruptly, from the base to the top of the emitter tips. The carbon gradient is implemented during the process step, in which an n-type silicon layer is formed from which the emitter tips are made in subsequent masking and etching steps. The amount of carbon makes the emitter tips harder and gives lower work function at greater stability. Moreover, the carbon gradient allows for additional sharpening of the emitter tips.
