Abstract: A flat panel display having a backplate structure (330), a faceplate structure (320), and a spacer (340) situated between the two plate structures is configured so that the electric potential field along the spacer approximates the potential field that would be present at the same location in free space, i.e., in the absence of the spacer, between the two plate structures. Consequently, the presence of the spacer does not significantly affect the trajectories of electrons moving from the backplate structure to the faceplate structures. Alternatively, the spacer is arranged to produce electron deflection that largely compensates for undesired electron deflection which occurs during earlier electron travel from the backplate structure to the faceplate structure. The net electron deflection is small.

Abstract: An electron-emitting device utilizes an emitter electrode (12) shaped like a ladder in which a line of emitter openings (18) extend through the electrode. In fabricating the device, the emitter openings can be utilized to self-align certain edges, such as edges (38C) of a focusing system (37), to other edges, such as edges (28C) of control electrodes (28), to obtain desired lateral spacings. The self-alignment is typically achieved with the assistance of a backside photolithographic exposure operation. The ladder shape of the emitter electrode also facilitates the removal of short-circuit defects involving the electrode.

Abstract: A liquid chemical formulation suitable for making a thin solid polycarbonate film contains polycarbonate material and a liquid typically capable of dissolving the polycarbonate to a concentration of at least 1 %. The liquid also typically has a boiling point of at least 80 °C. Examples of the liquid include pyridine, a ring-substituted pyridine derivative, pyrrole, a ring-substituted pyrrole derivative, pyrrolidine, a pyrrolidine derivative, chlorobenzene, and cyclohexanone. A liquid film (36A) of the liquid chemical formulation is formed over a substructure (30) and processed to remove the liquid. In subsequent steps, the resultant solid polycarbonate film can serve as a track layer through which charged particles (70) are passed to form charged-particle tracks (72). Apertures (74) are created through the track layer by a process that entails etching along the tracks. The aperture-containing polycarbonate track layer is typically employed in fabricating a gated electron-emitting device.

Abstract: Image degradation that can occur in a flat-panel CRT display as a result of electron deflection caused by energy flowing through a spacer system (16) in the display is alleviated by appropriately controlling thermal, electrical, and dimensional parameters of the spacer system. In particular, spacer parameter C is selected to be low. Parameter C equals alpha AVh /f kappa AV, where alpha AV is the average thermal coefficient of electrical resistivity of the spacer system, h is the height of the spacer system, kappa AV is the average thermal conductivity of the spacer system, and f is the fraction of the spacer cross-sectional area to the display's active area. Parameter C is normally 6X10 m /watt or less. Height h is normally 0.3 mm or more.

Abstract: An apparatus for removing contaminants from a display device (400) is disclosed. In one embodiment, an auxiliary chamber (408) is adapted to be coupled to a surface of a display device (400) such that contaminants within the display device can travel from the display device into the auxiliary chamber. A getter (410) is disposed in the auxiliary chamber (408). The getter is adapted to capture the contaminants once the contaminants travel from the display device (400) into the auxiliary chamber (408). In other embodiments, the getter is disposed in the border region surrounding the active area of the display.

Abstract: Methods and structures are provided which support spacer walls (100) in a position which facilitates installation of the spacer walls (100) between a faceplate and backplate of a flat display. In one embodiment, spacer feet (111, 112) are formed at the opposing ends of the spacer wall. Tacking electrodes can be provided on the faceplate to assert an electrostatic force on the spacer feet (111, 112), thereby holding the spacer feet in place during installation of the spacer wall. The spacer wall can be mechanically and/or thermally expanded prior to attaching both ends of the spacer wall to the faceplate. The spacer wall is then allowed to contract, thereby introducing tension into the spacer wall which tends to straighten any inherent wavines in the spacer wall. Alternatively, spacer clips can be clamped onto opposing ends of a spacer wall to support the spacer wall during installation. The spacer clips can provide electrical connections to face electrodes located on the spacer wall.
