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 gated electron-emitter is fabricated by a process in which particles (26) are deposited over an insulating layer (24). Gate material is provided over the insulating layer in the space between the particles after which the particles and any overlying material are removed. The remaining gate material forms a gate layer (28A or 48A) through which gate openings (30 or 50) extend at the locations of the removed particles. When the gate material deposition is performed so that part of the gate material extends into the spaces below the particles, the gate openings are beveled. The insulating layer is etched through the gate openings to form dielectric openings (32 or 52). Electron-emissive elements (36A or 56A) are formed in the dielectric openings. This typically involves introducing emitter material through the gate openings into the dielectric openings and using a lift-off layer (34), or an electrochemical technique, to remove excess emitter material.

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 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: 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 field emission display device has a faceplate and a backplate. The faceplate includes a faceplate interior side with an active region made of a plurality of phosphor pixel elements; and the backplate has a backplate interior side with a plurality of field emitters. Sidewalls are positioned between the faceplate and the backplate, to form an enclosed sealed envelope between the sidewalls, backplate interior side and the faceplate interior side. At least one spacer wall in the envelope supports the backplate and the faceplate against forces acting in a direction toward the envelope. At least one internal structure fixes and constrains the faceplate and the backplate, and aligns a plurality of phosphor pixels with corresponding field emitters. Additonally, the faceplate can include at least one faceplate fiducial, and the backplate include a corresponding backplate fiducial. The faceplate fiductial is optically aligned with the backplate fiducial. First, the spacer wall is positioned in the wall gripper. The faceplate and backplate fiducials are then optically aligned, and the spacer wall then introduced into the locator. Phosphor pixels are aligned with their corresponding field emitters. There is no need for external fixturing devices in the high temperature bonding and sealing processes of the display.

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: Openings are created in a structure by a process in which a plate (20) is furnished with a sacrificial patterned masking layer divided into multiple laterally separated mask portions (22A). A primary layer of actinic material (28) is provided over the masking layer and in the space between the mask portions. Material of the primary layer that is not shadowed by a mask formed with the mask portions is backside exposed to actinic radiation (30). Material of the primary layer not exposed to the radiation is removed. Segments of the masking layer not covered by exposed material of the primary layer are then removed. Consequently, openings extend through the primary layer where the segments of the masking layer have been removed. The process is typically employed in forming an optical device such as a flat-panel cathode-ray tube display in which the openings in the primary layer receive light-emissive material.
