Abstract: A blade assembly and a fan display including the same. The blade assembly includes a circuit substrate provided in an elongated shape, a lamination board provided in an elongated shape and bonded to the circuit substrate by a laminating glue, and a plurality of light emitting diode (LED) light emitting units. A mounting hole is defined in the lamination board and passes through a thickness of the lamination board. The circuit substrate has a first side attached to the lamination board, the first side and the mounting hole jointly defining a mounting cavity, in which plurality of LED light emitting units are hermetically disposed in the mounting cavity, and are arranged at intervals along a length of the circuit substrate.

Abstract: Some embodiments provide a full-color display module and display device. The full-color display module includes at least two light-emitting layers. Any one of the at least two light-emitting layers includes a substrate and a plurality of light-emitting portions encapsulated on the substrate. A type of any one of the plurality of light-emitting portions is one of a red light-emitting portion, a green light-emitting portion, and a blue light-emitting portion. The at least two light-emitting layers are successively laminated in a laminating direction and form a plurality of pixel points. Any one of the plurality of pixel points is a surrounding area on the full-color display module, which is surrounded by a surrounding curved surface. The surrounding area of the any one of the plurality of pixel points includes at least one red light-emitting portion, at least one green light-emitting portion, and at least one blue light-emitting portion.
