Abstract: The present invention relates to a field emission display using a gated field emitter and a flat electrode that is applied to a Cathode Ray Tube (CRT). The present invention does not need a spacer unlike the related invention and so the problem resulting from a mounting of the spacer is solved, and the structure of its whole panel and its fabrication process are simplified, thus improving its productivity and decreasing its fabrication cost.

Abstract: The present invention relates to an apparatus for manufacturing a diamond film having a large area which is used for a field emission display (FED) and a manufacturing method thereof.The apparatus for manufacturing a diamond film having a large area according to the present invention comprises a pulse laser generating system for generating a pulse laser beam, a laser beam scanner for scanning said pulse laser beam, and a vacuum chamber which includes a target and a substrate holder, wherein said laser beam having passed said laser beam scanner is irradiated on said target, and wherein a substrate on which a diamond film is to be formed by a plume produced from said target is set up to said substrate holder. The diamond film according to the present invention has a uniform electrical and mechanical properties and can be obtained in a short time period and with a uniform width and a large area.

Abstract: Evacuation of the volume of a field emission display can be carried out more easily by attaching the auxiliary chamber of various shape to the main space of a field emission display, which enlarge the volume of the field emission display. Several types of auxiliary chambers are attached to the main space of a field emission display and the resultant structures are described. The main purpose of the present invention is to introduce the method of providing the space for placing getters and increasing the conductance of the system to evacuate by enlarging the total volume of the field emission display.

Abstract: The invention is to provide the method for fabricating the spacers which are mechanically strong and have lower outgassing rate. Spacers in this invention are made of photosensitive glass. A net shaped photosensitive glass is etched by a first photolithography process and then the side wall of it is etched again by a second photolithography process for improving the efficiency of evacuation of the internal cavity of an FED.

Abstract: This invention describes the new structure of a field emission cathode based flat panel display that comprises a main space and an attached auxiliary space, whose volume is larger than that of the main space. In this structure evacuation of the volume of the FED can be carried out more easily. Also getters to eliminate a build up of pressure after sealing off process can be included in the auxiliary tank and high vacuum can be maintained for the lifetime of the FED.
