Micro light emitting diode chip and method for forming the same

Abstract

A micro-LED chip and a method for forming the same, wherein the micro-LED chip comprises: a first light-emitting portion, the first light-emitting portion comprises: a plurality of first pixel structures, each of which emits light of a first wavelength; a second light-emitting portion, the second light-emitting portion comprises: a plurality of second pixel structures, each of which emits light of a second wavelength, the first wavelength and the second wavelength being different; the first light-emitting portion and the second light-emitting portion are bonded to each other, and the first pixel structure and the corresponding second pixel structure are arranged relative to each other along the direction in which the components are stacked. By integrating light-emitting pixel structures that can emit light of different wavelengths into the same chip, pixel structures of different colors can be stacked on the same chip end, thereby effectively reducing the volume of chips of different colors when used together.
