The present disclosure relates to a manufacturing method of colorful Micro-LEDs. The method includes: bringing the array of the blue-light Micro-LEDs into contact with a first-color photosensitive solution and a second-color photosensitive solution; turning on first preset blue-light Micro-LEDs and the second preset blue-light Micro-LEDs of the array for conducting polymerization on the first and the second preset blue-light Micro-LEDs to form at least one lens. After the lens are formed, the first preset blue-light Micro-LEDs emit the light beams of the first color, the second preset blue-light Micro-LEDs emit the light beams of the second color, and the remaining blue-light Micro-LEDs emit the blue light beams to constitute three colors so as to obtain the colorful Micro-LEDs. In addition, the present disclosure also relates to a display module having the above array of the Micro-LEDs, and a terminal including the display module.
