Abstract: A micro semiconductor device includes an epitaxial structure and an optical layer. The optical layer is disposed on the epitaxial structure. The optical layer is a multi-layer film structure including a first film layer, a second film layer, and a third film layer disposed between the first film layer and the second film layer. A refractive index of the first film layer and a refractive index of the second film layer are both greater than a refractive index of the third film layer. A thickness of the third film layer is greater than a thickness of the first film layer and s thickness of the second film layer. A reflectivity of the optical layer to an external light of the micro semiconductor device is greater than a self-luminescence of the epitaxial structure of the micro semiconductor device.

Abstract: An electronic device is provided. The electronic device includes a substrate and a plurality of light-emitting assemblies. The substrate includes a first edge, an edge region, and a central region. The edge region is adjacent to the first edge. The central region is adjacent to the edge region and away from the first edge. The light-emitting assemblies are disposed on the substrate, and each of the light-emitting assemblies has a tuning element and a light-emitting element. The light-emitting assemblies further include a first light-emitting assembly and a second light-emitting assembly. The first light-emitting assembly is disposed in the central region and has a first light-emitting pattern. The second light-emitting assembly is disposed in the edge region and has a second light-emitting pattern. At a viewing angle of 60°, the brightness of the first light-emitting pattern is higher than the brightness of the second light-emitting pattern.

Abstract: A tiled display device is provided. The tiled display device includes a main supporting substrate, a first display substrate and a second display substrate. The first display substrate is disposed on the main supporting substrate. The second display substrate is disposed on the main supporting substrate and adjacent to the first display substrate. In addition, the main supporting substrate includes a light reflection reduction structure. In a top-view direction of the tiled display device, the light reflection reduction structure is overlapped with the gap between the first display substrate and the second display substrate.

Abstract: A pin header includes a plurality of pins and a seat body having a base portion and an extending portion. The extending portion has a connecting end connected to the base portion and having a cross section that overlaps a portion of and that is within a surface of the base portion. Each of the pins has a securing segment having a main portion and at least one protruding portion that protrudes transversely from the main portion. The extending portion of the seat body is formed with a plurality of spaced-apart internal receiving spaces, each of which corresponds in shape to and is engaged fittingly with the securing segment of a respective one of the pins so that the pins are secured to the seat body.
