Abstract: A flat-panel field emission display comprises a luminescent faceplate, a rigid backplate, and an interposed or sandwiched emitter or cathode plate. A positioning spacer or connector ridge is formed on the rear surface of the faceplate to space the cathode plate a fixed distance behind the faceplate. A peripheral seal is formed between the faceplate and the backplate. The faceplate, backplate, and peripheral seal define an evacuated internal space which contains the cathode plate. The backplate is spaced behind the cathode plate to create a rearward vacuum space in which a getter is located.

Abstract: A sealed, metal oxide, electrodeless discharge lamp having a high emission ntensity in the visible 400-700 nm range. Within the sealed container assembly of the lamp there is a source of metal atoms capable of forming a volatile oxide and a source of an oxygen containing gas. The lamp produces a plasma and volatilizes the metal into the plasma. Preferably the lamp is at a low pressure of about 20-40 torr and the metals are molybdenum or tungsten. Power is applied by inductively coupled electromagnetic radiation. A regenerative agent such as a halogen is added for recycling any deposited metal into the gas phase and to form a volatile compound with the source of metal atoms. The agent lowers the temperatures needed to volatilize the metal into the plasma. The lamp is operated by first providing energy at a low level to initiate the plasma and then supplying the metal atoms into the plasma.

Abstract: A second film that contains a substance that secures the conductivity of conductive particles is formed on a first film that contains the conductive particles. The first film and the second film are sintered at the same time. Thus, a conductive anti-reflection film having a sufficiently low surface resistance with a sufficient transmissivity for a high transparency can be obtained with high cost performance. When the conductive anti-reflection film is used for a cathode ray tube, it can almost prevent the AEF (Alternating Electric Field), display a picture in high quality, and be excellent in cost performance.

Abstract: An apparatus for removing contaminants from a display device using an auxiliary chamber, and a method for attaching the auxiliary chamber to the display device. In one embodiment, an auxiliary chamber is adapted to be coupled to a surface of a display device. The auxiliary chamber is adapted to be coupled to the surface of the display device such that contaminants within the display device can travel from the display device into the auxiliary chamber. The auxiliary chamber further includes a getter which is disposed therein. The getter is adapted to capture the contaminants once the contaminants travel from the display device into the auxiliary chamber. In so doing, the present invention eliminates the need for getter material to be placed within the active area of the display device. As a result, the present invention increases the usable amount of space available within the display device. This extra space can then be utilized by features such as, for example, additional field emitters.

Abstract: A plasma display having a transparent front panel spaced from a back panel which is a metal core having layers of a dielectric material extending over and bonded to the core. Conductive electrodes are on the surface of or imbedded in the dielectric layer of the back panel. The materials of which the back panel is made are chosen to form a back panel having a thermal coefficient of expansion compatible with that of the front panel. The dielectric material is made from a green ceramic tape which is bonded to the core and cofired with the core to form the back panel. Barrier ribs are formed on the back panel by embossing or scribing the green tape before cofiring the bonded assembly. Slight differences in the TCEs of the front and back panels may be compensated for by heating the panel having the lower TCE to a temperature hotter than the panel having the lower TCE during the frit seal process.

Abstract: An electronic display device includes a two-dimensional array of point charge sources, which are aligned with a plurality of apertures defined in a substrate. Associated with each aperture is a set of electrodes, including a focusing electrode, which in effect funnels the ions from the charge source into a narrow stream, and a plurality of displacing electrodes, through which the ion stream can be caused to scan over a small two-dimensional area on a phosphor. Modulating the bias on the focusing electrode can be used to control the ion stream passing through an individual aperture according to image data. The combined action of a two-dimensional array of charge sources and associated control devices can create a single composite image on the phosphor.

Abstract: A full-color, tunable organic light emitting diode (RCOLED) includes a high-reflection tunable membrane and a high-reflection dielectric mirror that form a resonant cavity. A white light OLED is located in the resonant cavity. The high-reflection tunable membrane is moved to alter the resonant cavity length, and/or tilted/bowed to change the finesse of the resonant cavity. In this way, color, brightness and color saturation of the emitted light from the RCOLED can be tuned. The RCOLED may also include a microlens structure to improve off-axis viewing.

Abstract: Direct and indirect electron bombardment provide a sufficiently high degree of temperature uniformity across the emitting surface of a large-area electron source for an electron beam projection system such that a broad beam having illumination uniformity within 1% can be achieved. A diode gun is used to obtain extraction field uniformity and maintain uniformity of illumination. Power requirements and power dissipation in beam periphery truncating apertures is reduced by roughening the surface of a monocrystalline cathode or depositing materials having a higher work function thereon.
