Micro-LED structure and micro-LED chip including same

A micro-LED chip including multiple micro-LEDs, wherein,

• at least one micro-LED of the multiple micro-LEDs comprises:
• a first type conductive layer;
• a second type conductive layer stacked on the first type conductive layer;
• a light emitting layer formed between the first type conductive layer and the second type conductive layer;
• a top spacer formed between the light emitting layer and the second type conductive layer;
• and
• a bottom spacer formed between the light emitting layer and the first type conductive layer,
• wherein the light emitting layer, the top spacer, and the bottom spacer are continuously formed on the whole micro-LED chip including the multiple micro-LEDs, the multiple micro-LEDs sharing the light emitting layer, the top spacer, and the bottom spacer,
• the micro-LED chip further comprises an isolation structure formed between adjacent micro-LEDs, at least a portion of the isolation structure being formed in the light emitting layer,
• a top surface of the isolation structure is above the light emitting layer,
• a bottom surface of the isolation structure is aligned with a bottom of the light emitting layer,
• the at least one micro-LED further comprises a reflective structure formed surrounding the first type conductive layer and directly attached on a sidewall of the first type conductive layer, and
• the reflective structure on the sidewall of the first type conductive layer is inclined relative to a surface of the light emitting layer, and an inclined angle of the reflective structure is approximately 30° to approximately 75° relative to the surface of the light emitting layer.
