Abstract
A method for fabricating a micro-light emitting diode (LED) display panel, including: forming a stack structure on a wafer substrate, the stack structure including a first metal layer, a first type of light emitting layer, a second metal layer, and a second type of light emitting layer in an order from bottom to top; forming a plurality of trenches in the stack structure, the plurality of trenches defining a plurality of micro LED display panel areas; patterning the second type of light emitting layer and the second metal layer; selectively etching the stack structure to expose a side surface of the first metal layer, thereby forming a plurality of first LEDs and a plurality of second LEDs in each micro LED display panel area; and cutting the wafer substrate to form a plurality of micro LED display panels.
