Abstract: A flat-panel display contains a pair of plate structures (20, 22) separated by a spacer (24) having a rough face (54, 56). When electrons strike the spacer, the roughness in the spacer's face causes the number of secondary electrons that escape the spacer to be reduced, thereby alleviating positive charge buildup on the spacer. As a result, the image produced by the display is improved. The spacer facial roughness can be achieved in various ways such as depressions and/or protuberances. Various techniques are presented for manufacturing the display, including the rough-faced spacer.

Abstract: A structure suitable for partial or full use in a spacer (24) of a flat panel display has a porous face (54). The structure (24) may be formed with multiple aggregates (100) of coated particles (102) bonded together in an open manner to form pores (58). A coating (88) consisting primarily of carbon and having a highly uniform thickness may extend into pores (58) of a porous body (46). The coating (88) can be created by removing non-carbon material from carbon-containing species provided alone the pores (58). A solid porous film (82) whose thickness is normally no more than 20 mu m has a resistivity of 10 - 10 ohm-cm. A spacer (24) for a flat panel display (Fig.1) contains a support body (80) and an overlaying, normally porous, layer (82) whose resistivity is greater parallel to a face of the support body then perpendicular to the body's face.

Abstract: An electron-emitting device contains a vertical emitter resistor patterned into multiple laterally separated sections (34, 34V, 46, or 46V) situated between the electron-emissive elements (40), on one hand, and emitter electrodes (32), on the other hand. Sections of the resistor are spaced apart along each emitter electrode. The resistor can be formed in a manner self aligned to control electrodes (38 or 52A/58B) of the device or with a separate resistor mask.

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.
