Abstract: A light guide assembly includes a housing element, at least one light guide element, and at least one light-shielding element. The housing element includes an outer surface and an inner surface. The light guide element is configured for a light to pass therethrough. The light guide element includes a light entrance surface, at least one light exit surface, and at least one wall surface. The wall surface surrounds and is connected to an edge of the light exit surface and extends toward the light entrance surface. The light exit surface is in contact with the inner surface. The at least one light-shielding element surrounds the at least one wall surface and is in contact with the inner surface.

Abstract: A detachable device includes a base, an object, and a latching structure. The object is detachably disposed over the base and has a fastening part. The latching structure is for detachably connecting the base and the object and includes a main body disposed on the base with a distance from the base. The main body includes a buckle part and a release part. The buckle part is for detachably buckling with the fastening part of the object. The release part is connected to the buckle part and is arranged on a side of the buckle part away from the fastening part. When being pushed by an external force, the release part drives the buckle part away from the fastening part, and the object is detached from the base.

Abstract: A method for forming a patterned conductive structure is provided. The method includes forming a soluble layer on a surface of a substrate, wherein the soluble layer has an opening exposing a rough portion of the surface. A first conductive layer is formed on the soluble layer, wherein the first conductive layer extends onto the rough portion in the opening. The soluble layer and the first conductive layer on the soluble layer are removed, wherein a portion of the first conductive layer corresponding to the rough portion is remained on the substrate. A patterned conductive structure formed by the method is also provided.
