Light-emitting structure including light-emitting units with different areas

Abstract

A light-emitting structure includes: a first region and a second region surrounding the first region. The first region includes a plurality of first light-emitting units, and the second region includes a plurality of second light-emitting units. An area of the first light-emitting unit is greater than an area of the second light-emitting unit. The area of the second light-emitting unit in the second region arranged on the edge is relatively small, which improves a doping rate of a light-emitting element in the second region, so that doping rates of the light-emitting element of the light-emitting structure in the first region and the second the area tend to be equal, thereby solving a problem of uneven light-emitting wavelengths in the first region and the second region when the light-emitting unit is prepared by epitaxy.
