Abstract
An image display unit includes first and second substrates spaced from each other, an electron source arranged on the first substrate, and an image display member arranged on the second substrate and having a first electric conductor. A second electric conductor is in contact with the first electric conductor through an opening formed in the first substrate. The second electric conductor has a holding member with a portion in contact with the first substrate and a portion joined to the first substrate through an adhesive. The holding member may also have a portion coming in contact with an outer surface of the first substrate and a portion joined to the outer surface of the first substrate through the adhesive.
Claims5
An image display unit comprising:
- (a) a first substrate having an opening and including an electron source disposed at a surface thereof;
- (b) a second substrate provided with an image forming member and a first electric conductor at a surface thereof, and being disposed such that the surface of said second substrate on which said image forming member is in opposition to the surface of said first substrate on which said electron source is disposed;
- (c) a frame fitted between said first and second substrates;
- and
- (d) a fitting member fitting the opening of the first substrate, said fitting member holding a second electric conductor coming in contact with said first electric conductor through the opening, wherein
- said fitting member comprises a first portion joined to said first substrate with an adhesive and a second portion directly in contact with a surface of said first substrate opposite to the surface on which said electron source is disposed.
An image display unit comprising:
- a rear plate having an opening and an electron source disposed on a surface thereof;
- a face plate disposed in opposition to said rear plate, said face plate including a phosphor emitting light responsive to irradiation with an electron beam emitted from said electron source, and an anode electrode for applying a voltage to said phosphor;
- a supporting frame sandwiched between said rear plate and said face plate;
- and
- an insulating member provided with an electrode extending through the opening in said rear plate and introducing a voltage into said anode electrode disposed on an inner surface of said face plate, wherein
- said insulating member fits the opening and comprises a first portion joined to said rear plate with an adhesive and a second portion directly contacting a rear surface of said rear plate opposite to the surface on which said electron source is disposed.
An image display unit comprising:
- (a) a first substrate having an opening and including an electron source disposed at a surface thereof;
- (b) a second substrate provided with an image forming member and a first electric conductor at a surface thereof, and being disposed such that the surface of said second substrate on which said image forming member is in opposition to the surface of said first substrate on which said electron source is disposed;
- (c) a frame fitted between said first and second substrates;
- and
- (d) a fitting member fitting the opening of the first substrate, said fitting member holding a second electric conductor coming in contact with said first electric conductor through the opening, wherein
- said fitting member comprises a first portion joined to said first substrate with an adhesive and a second portion in contact with a surface of said first substrate opposite to the surface on which said electron source is disposed without an adhesive.
