Abstract
A method of fabricating a micro light emitting diode (micro LED) array substrate having a plurality of micro LEDs. The method includes forming a plurality of signal lines on a base substrate; depositing a semiconductor material on the base substrate to form a semiconductor material layer; and patterning the semiconductor material layer to form a semiconductor layer of the plurality of micro LEDs. A surface of the plurality of signal lines away from the base substrate is uncovered during depositing the semiconductor material. The plurality of signal lines form a grid for facilitating epitaxial growth of the semiconductor material.
