Abstract: The present disclosure is applicable to a display device-related technical field and relates to, for example, a display device using a micro light-emitting diode (LED). The present disclosure as such comprises: a wiring board on which a plurality of unit pixel regions are defined; a wiring electrode arranged on the wiring board, the wiring electrode comprising a first wiring electrode and a second wiring electrode; and a light-emitting element that forms a sub-pixel by being installed to be electrically connected to the first wiring electrode and the second wiring electrode in each of the unit pixel regions, wherein the light-emitting element may be configured to comprise: a first light-emitting element located in a first pixel region and installed in a first arrangement; and a second light-emitting element located in a second pixel region neighboring the first pixel region and installed in a second arrangement that is symmetrical to the first arrangement.

Abstract: The present invention relates to a ceramic coating and ion beam mixing apparatus for improving corrosion resistance, and a method of reforming an interface between a coating material and a base material. In samples fabricated using the coating and ion beam mixing apparatus, adhesiveness is improved, and the base material is reinforced, thereby improving resistance to thermal stress at high temperatures and high-temperature corrosion resistance of a material to be used in a sulfuric acid decomposition apparatus for producing hydrogen.

Abstract: A high-temperature and high-pressure corrosion-resistant process heat exchanger for a nuclear hydrogen production system decomposes sulfite (SO3) using heat from a high-temperature gas-cooled reactor to thereby produce sulfide (SO2) and oxygen (O2). The process heat exchanger comprises second and third system coolant channels, each of which is defined by a heat transmission fin, which is bent in a quadrilateral shape, and heat transmission plates, and has increased corrosion resistance thanks to ion-beam coating and ion-beam mixing using a material having high corrosion resistance. The third system coolant channel includes reaction catalysts for SO3 decomposition, and is made of a super alloy. Thus, a system differential pressure between the second and third system coolant channels can be greatly maintained at a high temperature of 900° C. or higher.
