Abstract: A flat panel display is disclosed which includes a faceplate with a faceplate interior side, and a backplate including a backplate interior side in an opposing relationship to the faceplate interior side. Side walls are positioned between the faceplate and the backplate. The side walls, faceplate and backplate form an enclosed sealed envelope. A plurality of phosphor subpixels are positioned at the faceplate interior side. A plurality of field emitters are positioned at the backplate interior side. The field emitters emit electrons which strike corresponding phosphor subpixels. A plurality of scattering shields surround each phosphor subpixel and define a subpixel volume. The scattering shields reduce the number of scattered electrons exiting from their corresponding subpixel volume. This reduces the number of scattered electrons from charging internal insulating surfaces in the envelope, as well as striking the non-corresponding phosphor subpixels.

Abstract: Methods and structures are provided which reduce charge build up on spacer walls in a flat panel display. In one embodiment, the order of activating the electron emitting elements is modified such that the electron emitting elements adjacent to the spacers are activated before the electron emitting elements which charge thespacers (501, 502, 503) to an undesirable level. In another embodiment, face electrodes (501a, 502a, 503a) which are located on the surface of the spacer are connected to a common bus (504), thereby distributing the charge built up on any particular spacer. The common bus (504) can further be connected to a capacitor (1010) which is located either inside or outside the active region of the flat panel display, thereby increasing the charging time constant of the spacers. The capacitor can be connected to ground or to a high voltage supply (1011). In another embodiment, the charging time constant of the spacers is increased by fabricating the spacers from a material having a high dielectric constant, such as dispersion of aluminum oxide, chromium oxide and titanium oxide, wherein the titanium oxide makes up approximately four percent of the spacer material.

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.

Abstract: A method for creating a faceplate of a display provides a faceplate substrate with a faceplate interior side and a faceplate exterior side. A plurality of barriers are formed on the faceplate interior side, with the barriers defining a plurality of subpixel volumes. Phosphor containing photopolymerizable material mixtures of red, green and blue, are deposited into subpixel volumes, and create a faceplate interior side/phosphor interface. At least a portion of the phosphor containing photopolymerizable material mixture is exposed with sufficient actinic light through the faceplate interior side/phosphor interface to polymerize a selected depth of the phosphor containing photopolymerizable material mixture in the subpixel volumes, and form a polymerized phosphor containing material in a plurality of subpixel volumes. Non-polymerized phosphor containing photopolymerizable material is removed from the polymerized phosphor containing material.

Abstract: A voltage-adjustment section (20) of an electronic device converts an input control voltage (VI) into an output control voltage (VO) in such a way that a collector current (ICP) form with electrons emitted from an emitter (EP) of an emission/collection cell (26), or triode, varies in a desired, typically linear, manner with the input control voltage. The triode further includes a collector (CP) that carries the collector current and a gate electrode (GP) that regulates the collector current as a function of the output control voltage. Control of the collector current so as to achieve the desired current/voltage relationship is achieved with an analog control loop containing the triode and an amplifier (28) coupled between the triode's collector and gate electrode. The triode thus typically has a linear gamma characteristic relative to the input control voltage. The voltage-adjustment section is suitable for use in a display device such as a flat-panel display.

Abstract: An electron-emitter having a lower non-insulating emitter region (42), an overlying insulating layer (44), and a gate layer (48A, 60A, 60B, 120A, or 180A/184) is fabricated by a process in which particles (46) are distributed over one of the following layers: the insulating layer, the gate layer, a primary layer (50A, 62A, or 72) provided over the gate layer, a further layer (74) provided over the primary layer, or a pattern-transfer layer (182). The particles are utilized in defining gate openings (54, 66, 80, 122, or 186/188) through the gate layer. The gate openings are then variously employed in forming dielectric openings (56, 58, 80, 114, 128, 144, or 154) through the insulating layer. Electron-emissive elements that can, for example, be shaped like cones (58A or 70A) or like filaments (106B, 116B, 130A, 146A, or 156B) are formed in the dielectric openings.

Abstract: A method for creating a solid layer (36A or 52A) through which openings (38 or 54) extend entails subjecting particles (30) suspended in a fluid (26) to an electric field (EA) to cause a number of the particles to move towards, and accumulate over, a structure placed in the fluid. The structure, including the so-accumulated particles, is removed from the fluid. Solid material is deposited over the structure at least in the space between the so-accumulated particles. The particles, including any overlying material (36B or 52B), are removed. The remaining solid material forms the solid layer through which openings extend at the locations of the so-removed particles. The structure is typically a partially finished electron-emitting device. The solid layer is then typically either a gate layer for the electron-emitting device or a layer used in forming the gate layer.

Abstract: An electrochemical technique is employed for removing certain material from a partially finished structure without significantly chemically attacking certain other material of the same chemical type as the removed material. The partially finished structure contains a first electrically non-insulating layer (52C) consisting at least partially of first material, typically excess emitter material that accumulates during the deposition of the emitter material to form electron-emissive elements (52A) in an electron emitter, that overlies an electrically insulating layer (44). An electrically non-insulating member, such as an electron-emissive element, consisting at least partially of the first material is situated at least partly in an opening (50) extending through the insulating layer. With the partially finished structure so arranged, at least part of the first material of the first non-insulating layer is electrochemically removed such that the non-insulating member is exposed without significantly attacking the first material of the non-insulating member.

Abstract: A flat-panel device is fabricated by a process in which a pair of plate structures (40 and 42) are sealed along their interior surfaces (40A and 42B) to opposite edges (44A and 44B) of an outer wall (44) to form a compartment. Subsequently, exterior support structure (64) is attached to the exterior surface of one of the plate structures (40) to significantly increase resistance of the compartment to bending. Exterior support structure (66) is normally likewise attached to the exterior surface of the other plate structure (42) after the sealing operation. The compartment is then typically pumped down to a high vacuum through a suitable pump-out port (46) and closed. By providing the exterior support structure at such a relatively late stage in the fabrication process, the need for using spacers to support the device against external forces is eliminated or substantially reduced while simultaneously avoiding severe fabrication difficulties that arise in attaching the exterior support structure before the sealing operation.

Abstract: A getter (50 or 74) situated in a cavity of a hollow structure, such as a flat-panel device, is activated by directing light energy locally through part of the hollow structure and onto the getter. The light energy is typically provided by a laser beam (60). The getter, typically of the non-evaporable type, is usually inserted as a single piece of gettering material into the cavity. The getter normally can be activated/re-activated multiple times in this manner, typically during the sealing of different parts of the structure together. The getter-containing cavity can be formed by a pair of plate structures (40 and 42) sandwiched around and outer wall (44), or by an auxiliary compartment (72) connected to a larger main compartment (70) typically constituted by the plate structures and outer wall.
