Abstract

The present invention provides a micro-LED structure, including: a lower electrode layer; an ODR total reflection structure located on the lower electrode layer; a semiconductor light-emitting mesa located on the ODR total reflection structure, emitting light; and an upper electrode layer in contact with the top of the semiconductor light-emitting mesa. The micro-LED increases the probability of light leaving the light-emitting mesa by increasing the sidewall light emission area of the micro-LED structure, thereby improving the light emission efficiency of the LED chip.
