Abstract
A method for manufacturing a micro LED display is provided. The method includes providing a plurality of LED elements on a first substrate, transferring, using a magnetic holder or a vacuum holder, at least two of the plurality of LED elements of the same primary color from the first substrate to a second substrate, performing the steps of the providing and the transferring with respect to three primary colors, forming an array of RGB LED units on the second substrate, each of the array of RGB LED units including a red LED element, a green LED element, and a blue LED element, interposing the array of RGB LED units between the second substrate and an LED driver wafer, detaching the second substrate from the array of RGB LED units, and interposing the array of RGB LED units between the LED driver wafer and a cover.
