Abstract: A field emission display for reducing luminance unevenness by construction means. A plurality of stripe shaped cathode wirings 102 are formed in the cathode area 109 on a cathode substrate 101. Cut-through sections 108 are formed in each of the cathode wirings 102 and an island-like electrode 107 is formed within each cut-through section 108. A resistance layer 103 is formed on the cathode wiring 102, the cut-through section 108 and the island-like electrode 107. A plurality of emitter cones 106 are formed on the resistance layer 103 so as to provide a field emission array. The distance between the island-like electrode 107 and the cathode wiring 102 is changed depending on the position thereof in the cathode area 109 so as to correct deviation of the emission characteristic depending on the position. In the case of a full-color field emission display, white balance can be corrected by changing the distance depending on the luminous color of each dot.

Abstract: A super high resolution cold cathode fluorescent display (CFD) utilizes an anode with cathodoluminescent means, a cathode with field emission cathode group array, a glass like spacer plate structure providing an array of funnel-shaped channels. Each channel has a narrow aperture which serves as a pin hole for passage of electrons between the cathodes and anode. The display uses a circuit for generating a strong electric field between the anode and cathode in the array of channels to take advantage of the pin hole imaging effect to produce high resolution, full color images for the display.

Abstract: An apparatus and method for exposing a treatment site in a patient to x-ray radiation is described that uses a pulse voltage source (105), where the x-ray emitter (101) employs a cold cathode. The invention may further include a current sensor (111) for measuring a current through the x-ray emitter (101), and, optionally, a current integrator (113) connected to the current sensor (111). Each voltage pulse may be discontinued when a predetermined amount of charge has passed through the emitter (101). The step of moving an x-ray emitter (101) past a treatment area at a rate determined by the amount of charge that has passed through the emitter (101) is also described. The present invention also includes an x-ray emitter device (101) with rectangular voltage pulses added to a base direct current voltage. Another step of the invention may be applying a voltage pulse cycle to the x-ray emitter (101) where a duration of the pulse is 2-5 times lower than a thermal relaxation time of an emitter (101).

Abstract: A structure to reduce the likelihood of flashover in a parallel plate electron beam array is disclosed. The structure may comprise a means for generating a low intensity electric field in the vicinity of a spacer (200) separating the parallel plate of the array (100), and the anode (300).

The electric field means may be provided by a conductive coating (240) on one or more surfaces of the spacer. Alternatively, the electric field means may be provided by a conductive coating on a guard ring located within the array in the vicinity of the spacer. Methods of making the structure are also disclosed.
