The　three-primary-color　chip　array　is　the　most　straightforward　to　realize　full-color　micro-LED　displays.　However,　the　luminous　intensity　distribution　shows　high　inconsistency　between　the　AlInP-based　red　micro-LED　and　GaN-based　blue　/　green　micro-LEDs,　resulting　in　the　issue　of　angular　color　shift　with　different　viewing　angles.　This　Letter　analyzes　the　angular　dependence　of　color　difference　of　conventional　three-primary-color　micro-LEDs,　and　proves　that　the　inclined　sidewall　with　homogeneous　Ag　coating　has　a　limited　angular　regulation　effect　for　micro-LEDs.　Based　on　this,　a　patterned　conical　microstructure　array　is　designed　on　the　micro-LED’s　bottom　layer　to　effectively　eliminate　the　color　shift.　This　design　cannot　only　regulate　the　emission　of　full-color　micro-LEDs　to　perfectly　meet　Lambert’s　cosine　law　without　any　external　beam　shaping　elements,　but　also　improve　the　light　extraction　efficiency　of　top　emission　by　16%,　161%,　and　228%　for　red,　green,　and　blue　micro-LEDs,　respectively.　The　color　shift　∆u′v′　of　the　full-color　micro-LED　display　is　also　kept　below　0.02　with　the　viewing　angle　ranging　from　10°　to　90°.　©　2023　Optica　Publishing　Group.
