摘要:
A cathode ray tube includes a panel and a reinforcing band for implosion-protection that is located around a side wall of the panel. The reinforcing band is formed by folding over one side in a width direction of a belt-like metal plate (6) so as to have a partially twofold structure and by joining both end portions of the belt-like metal plate (6) so as to be in the shape of a closed loop extending along the side wall of the panel. One end portion and the other end portion of the both end portions are joined together so as to achieve a threefold structure in at least one part. This can achieve a strong reinforcing band at a low cost without using a special member.

A display device (1) is provided with a window frame (7). This window frame is arranged on the front wall (2). A vacuum-tight connection (10) is formed between the window frame and the front wall, and between the window frame and a rear wall (3) or a projecting portion of an intermediate element (4). Said window frame reduces the risk of leakage, reinforces the construction and enables an improved method of manufacturing the display device to be achieved.

摘要:
Openings are created in a structure by a process in which a plate is furnished with a sacrificial patterned masking layer divided into multiple laterally separated mask portions. A primary layer of actinic material is provided over the masking layer and in space between the mask portions. Material of the primary layer not shadowed by a mask formed with the mask portions is backside exposed to actinic radiation. 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.

A flat panel display (300) having a faceplate structure (320), a backplate structure (330), a focusing structure (333a), and a plurality of spacers (340). The backplate structure includes an electron emitting structure (332) which faces the faceplate structure. The focusing structure has a first surface which is located on the electron emitting structure, and a second surface which extends away from the electron emitting structure. The electrical end of the combination of the focusing structure and the electron emitting structure is located at an imaginary plane located intermediate the first and second surfaces of the focusing structure. The spacers are located between the focusing structure and the light emitting structure. Each spacer is located within a corresponding groove in the focusing structure such that the electrical end of each spacer is located coincident with the electrical end of the combination of the focusing structure and the electron emitting structure.

A field emission display (400) includes a cathode plate (410), an anode plate (430), and a mechanical support/getter assembly (300) being disposed between the cathode plate (410) and the anode plate (430). The mechanical support/getter assembly (300) includes a unitary spacer/frame assembly (310) made from a photosensitive glass. A method for fabricating the mechanical support/getter assembly (300) includes the steps of: selectively exposing inter-spacer regions and a getter frame region of a layer of the photosensitive glass to UV radiation, heating the layer to crystallize the UV-exposed regions, and removing the crystallized getter frame regions by contacting the layer with an acid, thereby forming spacer ribs and a getter land. The method further includes providing a getter frame (320) on the getter land.

A method of producing a cathode-ray tube apparatus having a light-transmitting film provided on the panel glass thereof includes a process for treatment of the surface of the panel glass including the steps of: coating a surface of the panel glass (4) which has been subjected to no external polishing with an ultraviolet-curing resin composition which gives a cured material (11) having a refractive index substantially the same as that of said panel glass (4); providing a light-transmitting film (12) on said ultraviolet-curing resin composition (11); and curing said ultraviolet-curing resin composition (11) by irradiation with ultraviolet radiation, thereby integrating said panel glass (4), ultraviolet-curing resin composition (11) and light-transmitting film (12) into one unit; wherein said panel glass (4) provided with the light-transmitting film (12) is accommodated in a vacuum container (16) at least one side of which is made of a transparent rubber sheet (17) which transmits ultraviolet radiation, and while said vacuum container (16) is being evacuated, said light-transmitting film (12) is squeegeed through said transparent rubber sheet (17), and said ultraviolet-curing resin composition (11a) is cured by irradiation with ultraviolet radiation through said transparent rubber sheet (17).
