摘要:
A light emission device having an evaporating getter unit and a display device utilizing the light emission device as a light source. The light emission device includes a vacuum vessel having first and second substrates facing each other and a sealing member, the first and second substrates having an active area and a non-active area, an electron emission unit located on the first substrate at the active area, a light emission unit located on the second substrate at the active area, a getter unit provided between the first and second substrates at the non-active area, and a barrier disposed between the getter unit and the active area. The barrier blocks diffusion of getter material toward the active area during the getter activating process and prevents (or reduces) a slip or a movement of the getter unit.

An electron emission display includes: an electron emission substrate having at least one electron emission device formed thereon, an image forming substrate, and at least two spacers for supporting the electron emission substrate and the image forming substrate to be spaced apart from each other. Areas of the spacers per unit area are increased in at least one direction from a central region to a periphery region. The areas can be increased by, for example, increasing a cross-sectional area of each spacer or increasing the number of spacers. In another embodiment, heights of the spacers are decreased in at least one direction from the center region to the periphery region.

A vacuum vessel includes a first substrate, a second substrate facing the first substrate and spaced apart therefrom, and support frames mounted along the edges of the first and the second substrates. At least two support frames are separately formed on at least one side of the first and the second substrates. Adhesive layers are placed on a surface of the support frame facing the first substrate as well as on the opposite-surface of the support frame facing the second substrate to attach the two substrates and the support frames to each other. A filler is disposed between the neighboring support frames to prevent the vacuum leakage.

An electron emission display device includes first and second substrates facing each other with a predetermined distance therebetween, an electron emission unit formed at the first substrate, and an image display unit formed at the second substrate. A grid electrode is disposed between the first and the second substrates and has a plurality of beam guide holes arranged in a first predetermined pattern, and spacer insertion holes arranged in a second predetermined pattern. Spacers are inserted into the respective spacer insertion holes of the grid electrode, and are fitted between the first and the second substrates. The size of each of the spacer insertion holes is larger than the outer size of each of the spacers.

An electron emission display comprises: a first plate and a second plate disposed in opposition to each other; a first electrode and a second electrode formed on the first plate and insulated from each other; an electron emission region connected to the first electrode or the second electrode for emitting electrons; a third electrode formed with at least one opening through which the electrons emitted from the electron emission region pass; a spacer supporting the first plate and the second plate so that they are spaced apart from each other; a metal coating layer formed on at least one region of the third electrode facing the spacer; a fourth electrode formed on the second plate; and a fluorescent layer connected to the fourth electrode. With this configuration, abnormal light-emission due to the spacer is prevented.
摘要:
A light emitting device capable of simplifying its manufacturing process and/or suppress vacuum leakage by improving its terminal structure and a display device having the same. The light emitting device includes a first substrate assembly, a second substrate assembly, and a sealing member for bonding the first substrate assembly with the second substrate assembly. The first substrate assembly includes a first substrate main body having recess portions, first electrodes within the recess portions, electron emission regions on the first electrodes, and second electrodes at a distance away from the electron emission regions and fixed to a surface of the first substrate assembly. Here, a first portion of the second electrode including a first end portion of the second electrode is exposed out of a region surrounded by the seal member and out of the seal member and is used as a terminal connected to an external circuit.
