Abstract: An embodiment of the present invention provides a micro light emitting diode (LED) array and its manufacturing method. The micro-LED includes a substrate, an epitaxial layer formed on the substrate, and a conversion film formed on the epitaxial layer. Pixels can be defined through lithography, and the pixel size can be very small. This method is characterized in that a mass transfer is not required.

Abstract: A light-emitting thin film is provided with one or more light-emitting materials and a host. Each light-emitting material is capable of absorbing photons or electromagnetic waves and re-radiating photons or electromagnetic waves after the absorption. The host is used to eliminate grain boundaries and mitigate scattering of the light-emitting materials after the film is formed. Preferably the light-emitting thin film is made of a solution process. A head-up display using the light-emitting thin film is also disclosed.

Abstract: An electroluminescent (EL) device is disclosed. An optically reflective concave structure includes a first surface and a second surface that lies at an angle relative to the first surface, wherein at least the first and second surfaces are optically reflective. One or more functional layers include a light emitting layer, disposed over the surfaces of the optically reflective concave structure, wherein at least one electroluminescent area of the light emitting layer is defined on the first surface. Especially, the ratio between the diameter of the first surface and the thickness of the one or more functional layers in the optically reflective concave structure is smaller than a constant value.
