A Micro LED light projection chip (6) and a method for manufacturing same. On the face of a substrate (4) of a wafer that is away from a metal electrode, an integrated lens (5) is manufactured according to a preset array pattern and on the basis of the substrate (4), such that a chip (6) can integrate the lens (5) without the need to use an additional lens or optical component; the integrated chip (6) can be obtained by cutting the wafer, and a chip (6) with a high integration level, a high pixel density and a small size can be obtained by means of a plurality of sub-pixels on the integrated chip (6); and each pixel on the chip (6) corresponds to a driving base (8), such that the effects of the resolution being adjustable and pixels being freely partitioned are achieved by means of driving design.

Sur la face d'un substrat (4) d'une tranche qui est éloignée d'une électrode métallique, une lentille intégrée (5) est fabriquée selon un
