  • Publication number: 20220199587
    Abstract: A light source assembly, a method for making same, and a display device using same are disclosed. The light source assembly includes a circuit substrate, an opaque and light-reflecting colloidal layer on the circuit substrate, micro light-emitting elements electrically connected to the circuit substrate, a base layer, a layer of convex lenses, and a layer of immediately-adjacent concave lenses. The colloidal layer defines grooves. At least two micro light-emitting elements each emitting light of a different color are arranged in each groove. The base layer is infilled into each groove and covers each micro light-emitting element. Each groove is covered by a convex lens which converges the emitted light. Each concave lens, covering one convex lens, substantially corrects optical path deviations of light of different wavelengths (that is, different colors), so reducing chromatic aberrations.
