Abstract
Disclosed are an LED structure and a preparing method of an LED structure. The LED structure includes: an LED light emitting unit including a first semiconductor layer, a light emitting layer and a second semiconductor layer which are stacked; and a first stress layer surrounding the LED light emitting unit and covering a side wall of the LED light emitting unit. In the present disclosure, the first stress layer is configured to apply a stress to the side wall of the LED light emitting unit, adjust a wavelength of the LED structure, and improve a wavelength uniformity of the LED structure. In addition, since a side wall of the LED structure is extruded, and a luminous efficiency of the LED structure is effectively improved.
