Abstract
The present disclosure provides a full-color LED structure, a full-color LED structure unit, and a method for manufacturing the same. Different wavelengths of light emitted from the first sub-region, the second sub-region and the third sub-region of the light-emitting layer are achieved by controlling different surface dimensions of the bottom wall and the side wall of the first trench or the top wall of the first semiconductor layer. The above process is simple and can form full-color LED structure units during a single epitaxial growth process of the light-emitting layer, such that the size of the full-color LED is reduced, the cost is reduced, the service life is extended, and the reliability is improved.
