摘要:
A light emission device and a display device using the light emission device as a light source are provided. The light emission device includes a vacuum envelope formed by first and second substrates (12,14) and a sealing member (16), first electrodes (28) formed on the first substrate in a first direction, an insulating layer (26) formed on the first substrate and covering the first electrodes, second electrodes (30) formed on the insulating layer in a second direction crossing the first direction, electron emission regions (32) electrically connected to the first electrodes or the second electrodes, a resistive layer (34a) for covering a first surface of the insulating layer, the first surface facing the second substrate, a phosphor layer (36) formed on the second substrate, and an anode electrode (38) formed on the phosphor layer.

An electron emission device includes a substrate, first electrodes formed on the substrate, electron emission regions electrically connected to the first electrodes, and second electrodes placed over the first electrodes such that the second electrodes are insulated from the first electrodes. The second electrodes have openings to expose the electron emission regions. A third electrode is placed over the second electrodes such that the third electrode is insulated from the second electrodes. The third electrode has openings communicating with the openings of the second electrodes. Each of the electron emission regions and the second electrodes simultaneously satisfy the following conditions: D 2 / D 1 ≤ 0.579 and D 2 ≥ 1 μm where D1 indicates the width of each of the openings of the second electrode, and D2 indicates the width of each of the electron emission regions.

An image display device includes a first substrate (10) having a phosphor screen, and a second substrate opposed to the first substrate across a gap and having a plurality of electron emission sources (18) which excite the phosphor screen. A spacer assembly (22) which supports atmospheric load acting on the first and second substrates is arranged between the first and second substrates. The spacer assembly has a plate-shaped spacer support member (24) which is arranged between the first and second substrates and has a plurality of electron beam apertures (26) opposed to the electron emission sources, individually, and a plurality of spacers (30) set up only on the second substrate side of the spacer support member and individually abutting against the second substrate.

A protected faceplate structure (900) includes a faceplate (100) and a barrier layer (902) of silica. The faceplate (100) may be made of soda glass, and the barrier layer (902) may be made of silica.
摘要:
A ferromagnetic shielding funnel for reception within the conical portion of a cathode ray tube having support members at the corner portions of its wider end. The support members project over a small distance into the inner space of the funnel for forming reference faces. The funnel has indentations so that, when two funnels are stacked one upon the other, the indentations in the lower funnel receive the inwardly projecting portions of the support members of the upper funnel, so that damage during and after stacking is prevented.
摘要:
A ferromagnetic shielding funnel having a flange at its wider end for reception within the conical portion of a cathode ray tube, the funnel having support members at the corner portions of its flange. Each support member has a base plate which is attached to the flange and a distal end which has been bent into a V-shape for bearing on a respective pin in the wall of the cathode ray tube. For preventing that the funnel comes loose from the pins, the support members comprise further attachment means with which they are attached to a skirt of the flange. Preferably, the base plate is attached to the flange by means of two first connections to a flange portion which is parallel to a long side of the cone portion and two second connections to a flange portion which is parallel to a short side of the cone portion. The extreme ones of these connections are preferably arranged such that bending of the flange at the corner portions is prevented.
摘要:
Colour display tube of the 3-in-line type having a display screen with a pattern of phosphor lines. The display tube has an internal shield with two long walls and two short walls. Each long wall is provided with at least one slit extending in the longitudinal direction of the tube and being remote from the edges of the walls, while for locally increasing the magnetic resistance the shield is particularly provided with a short transverse slit between at least one slit end and the opposite edge.
