Each micro light-emitting diode includes a semiconductor epitaxial stacked layer, which includes a first-type semiconductor layer, an active layer and a second-type semiconductor layer, and comprises a first surface and a second surface; the first surface is located on a side near the first-type semiconductor layer, the second surface is located on a side near the second-type semiconductor layer, and the first surface faces towards the substrate; and an adhesive film layer, which is located between the substrate and the semiconductor epitaxial stacked layer. An etching protective layer is disposed between the adhesive film layer and the first surface.

Abstract: A single light emitting diode (LED) structure includes an array of spaced discrete light emitting zones separated by isolation areas. Each emitting zone includes an epitaxial structure configured to emit an emitting light having a particular wavelength over an effective emission area. In addition, the effective emission area for each emitting zone can be geometrically defined and electrically configured to provide a desired light intensity. For example, each effective emission area can have a selected size and spacing depending on the application and light intensity requirements. Each emitting zone also includes a wavelength conversion member on its effective emission area configured to convert an emitting wavelength of the emitting light to a different color. The single (LED) structure can include multiple colors at different zones to produce a desired spectra or design. The single (LED) structure can also include a substrate for supporting the array, and the substrate can include one or more light shielding holes located between each emitting zone.
