Abstract
A micro-LED chip includes multiple micro-LEDs. At least one micro-LED of the multiple micro-LEDs includes: a first type conductive layer; a second type conductive layer stacked on the first type conductive layer; and a light emitting layer formed between the first type conductive layer and the second type conductive layer. The light emitting layer is continuously formed on the whole micro-LED chip, the multiple micro-LEDs sharing the light emitting layer. An isolation structure is formed between adjacent micro-LEDs, at least a portion of the isolation structure being formed in the light emitting layer.
Claims20
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;
- and
- a light emitting layer formed between the first type conductive layer and the second type conductive layer,
- wherein the light emitting layer is continuously formed on the whole micro-LED chip, the multiple micro-LEDs sharing the light emitting layer,
- an isolation structure is formed between adjacent micro-LEDs, at least a portion of the isolation structure being formed in the light emitting layer, and
- the micro-LED chip further comprises:
- 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 each one of the top spacer and the bottom spacer is continuously formed on the whole micro-LED chip, and the multiple micro-LEDs share the top spacer and the bottom spacer, and
- a top surface of the isolation structure is above a top surface of the second type conductive layer, and
- the isolation structure is spaced apart from a sidewall of each one of the multiple micro-LEDs, exposing a portion of the top spacer between the adjacent micro-LEDs.
