Graphene/metal nanocomposite powder and a method of preparing the same are provided. The graphene/metal nanocomposite powder includes a base metal and graphenes dispersed in the base metal. The graphenes act as a reinforcing material for the base metal. The graphenes are interposed as thin film types between metal particles of the base metal and bonded to the metal particles. The graphenes contained in the base metal have a volume fraction exceeding 0 vol % and less than 30 vol % corresponding to a limit within which a structural change of the graphenes due to a reaction between the graphenes is prevented.

摘要:
A spacer for an electron emission display and an electron emission display containing the spacer. The spacer includes an insulating member having a predetermined shape, and at least one inner electrode laterally inserted into the insulating member. A portion of the inner electrode is exposed to an outer side of the insulating member.

A spacer which can effectively discharge secondary electrons and an electron emission display having the spacer include: a main body disposed between first and second substrates which have first and second electrode layers, respectively; and a coating layer formed on a side surface of the main body. The coating layer has a first portion contacting one of the first and second electrode layers and a second portion formed on a central portion of the side surface of the main body. A thickness of the first portion is greater than that of the second portion.
摘要:
An electron emission display device includes first and second substrates facing each other, an electron emission unit located on the first substrate, and a light emission unit located on the second substrate to emit visible light in response to electrons emitted from the electron emission unit. Spacers are arranged between the first and second substrates. First support members are formed on the first substrate or the second substrate and are spaced apart from the spacers.
摘要:
Disclosed is a flat panel display device for preventing a grid electrode from causing alignment error and being distorted due to thermal expansion and contraction. The grid electrode includes a mask portion with apertures through which electrons may pass, and fixtures arranged external to the mask portion with a predetermined margin for allowing thermal expansion and contraction of the mask portion. The fixtures are arranged symmetrical to each other up and down as well as left and right. The fixtures fix the mask portion such that the expansion and the extraction of the mask portion proceed opposite to one another.
摘要:
A field emission display including a first substrate and a second substrate opposing one another with a predetermined gap therebetween. An electron emission assembly is formed on the first substrate that emits electrons by the formation of an electric field. An illumination assembly is formed on the second substrate that realizes the display of images by the emitted electrons. A grid plate is mounted between the first and second substrates and functions to focus the emitted electrons. The grid plate includes a mask section having a plurality of apertures for passing the electrons, and supports mounted to one side of the mask section and extending in a direction toward the first substrate to rest on the same and support the mask section. The mask section and the supports are made of same material or two different materials.
