Abstract
The invention relates to a patterned microstructure of a light emitting diode (LED) substrate. The substrate is provided with patterned microstructures arranged in an array. Each patterned microstructure includes a bottom surface and a lateral surface adjacent to the bottom surface. There is an angle θ between the lateral surface and the bottom surface, where 0°<θ<90°. The length of the bottom surface ranges between 2.5 microns and 2.8 microns. An end of the lateral surface far away from the bottom surface is gradually shrunk into an intersection, and the height between the intersection and the bottom surface ranges between 1.5 microns and 1.9 microns. Accordingly, the invention can effectively achieve improving light extraction efficiency of the LED by optimizing the size of the patterned microstructure cyclically and alternately arranged on the LED substrate.
