Abstract:
A luminescent alphanumeric indicating tube comprising an array of fluorescent segments formed on one surface of an insulating substrate, each segment including a carbon layer coated on the surface of the substrate and a first fluorescent layer interposed between the carbon layer and a second fluorescent layer, the first layer consisting fluorescent particles whose diameter is nearly equal to or smaller than that of the particles constituting the carbon layer and the second layer consisting of fluorescent particles whose diameter is larger than that of the particles consistuting the first fluorescent layer.
Abstract:
A flat panel field emission device includes a black matrix formed from an electrically insulative material such as praseodymium-manganese oxide. The insulative black matrix increases image contrast and reduces power consumption. For field emission devices which utilize a switched anode for selectively activating pixels, the insulative material reduces or eliminates problems associated with short circuiting of the pixels.

Abstract:
A spacer structure for use in a flat panel display, and a corresponding flat panel display article are disclosed, together with an appertaining method of fabricating the spacer structure utilizing a photosensitive precursor material which is selectively irradiated, developed and etchingly processed to produce shaped standoff elements for a unitary spacer structure. The spacer structure may be dimensionally fabricated to precisely align with a selected pixel region, comprising a single pixel or an array of pixels, e.g., a color (red, blue, green) triad.
Abstract:
A field emission display includes an insulating layer and an emitting layer disposed on the faceplate. A vacuum chamber is disposed between a backplane and the emitting layer and contains a getter. Apertures are defined through the insulating layer and the emitting layer for communicating contaminates from the faceplate to the vacuum chamber.
Abstract:
A multi-digit luminescence display tube comprises an anode assembly including a plurality of luminescent anode segments for each digit, a cathode, a plurality of grids disposed between the cathode and the anode segments of the respective digits, structure for supplying first voltages to the grids and to at least a selected one of the anode segments to make the same luminesce, and apparatus for superposing a second voltage on the first voltage supplied to at least a selected one of the grids to suppress luminescence at the anode segments covered thereby. The cathode comprises a common filament for the anode segments of all digits. Structure is provided for rendering the second voltage non-negative without adversely affecting the brightness of the selected anode segment which are not covered by the selected grid.
Abstract:
A three-dimensional display device including a cathode ray tube having a plurality of spaced, parallel light and electron pervious display planes. Each of the display planes is divided into a plurality of display zones disposed in a two-dimensional array such that a line perpendicular to any display zone passes through a corresponding display zone in every display plane. Each of the display zones is provided with a single luminescent element of smaller area than that of the display zone. The luminescent elements on successive corresponding display zones are nonoverlapping so that substantially all of the luminescent elements are visible from one end of the plurality of display planes, and an electron beam from a gun disposed at one end of said plurality of display planes may readily impinge against selected ones of the luminescent elements in any one of said planes. The single display plane whose luminescent elements are to be excited at any given time is selected in accordance with a depth signal, and the elements to be excited are then selected by sweeping and modulating the beam.

Abstract:
An organic light emitting diode display and a method for manufacturing the same are provided. The organic light emitting diode display includes a display substrate having an organic light emitting diode, an encapsulation substrate arranged opposite to the display substrate, and a sealant is applied between the display substrate and the encapsulation substrate to bond and form a hermetically sealed enclosed space therein. A filler may also be provided in some of the enclosed space. Spacers are formed on at least one of the display substrate and the encapsulation substrate to maintain a predetermined gap between the display substrate and the encapsulation substrate. The heights of the spacers are gradually increased from a central portion of the display substrate toward edges of the display substrate.
