Disclosed is an electron gun assembling method used for assembling a first electrode having a plurality of beam apertures as opposed to one cathode used as an electron beam emitting source with a cathode structure having the cathode. The method includes: a first step of rotating the cathode structure on its axis in a state in which the cathode structure is opposed to the first electrode, and measuring, during rotation of the cathode structure, a distance between each of the beam apertures of the first electrode and a beam emission plane of the cathode; and a second step of setting a rotational position of the cathode structure on the basis of the result measured in the first step. In the second step, particularly, the rotational position of the cathode structure may be set under a condition that the maximum one of the differences between the distances from the beam apertures of the first electrode to the beam emission plane of the cathode is minimized. With this assembling method, it is possible to reduce a variation in operational characteristics of the electron gun, such as a cutoff characteristic.

Method for welding a mask in a flat cathode ray tube, including applying an initial tensile force to a shadow mask to prevent deformation, and fastening the shadow mask to a rail by welding, wherein fastening the shadow mask includes performing a primary spot welding having relatively long primary welding spot intervals between primary welding spots, and a secondary spot welding having secondary welding spot intervals between secondary welding spots shorter than the primary welding spot intervals.
摘要:
A shadow mask for a color cathode ray tube provided which includes an effective surface part having a plurality of slots formed therein for passing electron beams, and an edge part extended from the effective surface part and welded to a frame fitted to a panel in a cathode ray tube. The shadow mask is tensed in any one of an x- and y-axis directions. An interval of welding spots on the edge part is fixed according to a thickness of the shadow mask and a pitch of slots of the shadow mask. The interval of welding spots is in a range of approximately 11 to 15 times the thickness of the shadow mask. The welding spots on the edge part has an aspect ratio in a range of approximately 1.0 to 2.6.
摘要:
A tile (10) having a plurality of grooves (22). An array of tiles (10) is assembled by placing at least two tiles (10) in generally opposing relationship to one another, with the grooves (22) substantially juxtaposed to define wells (38). When intended for incorporation into a device (40), such as a display device, a conductive interconnect (36) is formed in the wells (38). Devices include a base substrate (40), a first plate (46) and a second plate (48). A first member (50) may be employed to separate the base substrate (40) from the first plate (46). A second member (52) may be employed to separate the first plate (46) from the second plate (48).
摘要:
A process is provided for forming spacers useful in large area displays. The process comprises steps of: forming bundles or boules comprising fiber strands which are held together with a binder; slicing the bundles or boules into slices; adhering the slices on an electrode plate of the display; and removing the binder. In the step of forming bundles or boules comprising fiber strands, the function of the binder is initially or fully performed by glass tubings surrounding the glass fibers. The clad glass of the envelopes etches more readily than the core glass.
