Shanghai Xianyao Display applies for patents for micro-LED structure and micro-display panel

The patent abstract shows that a miniature light-emitting diode (LED) structure includes a mesa structure. The mesa structure further includes a first semiconductor layer, a light-emitting layer formed on the first semiconductor layer, a second semiconductor layer formed on the light-emitting layer, a sidewall protective layer formed on a sidewall of the mesa structure, and a sidewall reflective layer formed on a surface of the sidewall protective layer. The top surface area of ​​the second semiconductor layer is greater than each of: the bottom surface area of ​​the first semiconductor layer, the top surface area of ​​the first semiconductor layer, and the bottom surface area of ​​the second semiconductor layer.
