Abstract: An electronic device includes a substrate, an electronic component, a first blocking structure and a packaging layer. The substrate defines a normal direction perpendicular to a surface of the substrate. The electronic component is disposed on the substrate. The first blocking structure is disposed adjacent to a side of the electronic component. The packaging layer is disposed on the electronic component and has a refractive index n at a wavelength of 550 nm. The electronic component has a width W in a first direction perpendicular to the normal direction. A distance H is between a surface of the first blocking structure away from the substrate and the surface of the substrate in the normal direction. A spaced distance P1 is between the surface of the first blocking structure away from the substrate and the electronic component in the first direction. Following relationship is satisfied: H=n×[(P1+W)/tan ?].

Abstract: An electronic device, including a substrate, multiple light emitting elements, an optical switching unit, and multiple micro lenses, is provided. The light emitting elements are disposed on the substrate. The optical switching unit is disposed on the light emitting elements. The micro lenses are disposed on the light emitting elements and overlap with the optical switching unit. At least one of the light emitting elements is disposed corresponding to one of the micro lenses.
