Abstract: A method for auxiliary assembling micro-components though liquid medium. This method includes following steps: providing a substrate, an adhesive layer, at least one micro-component and a liquid medium, wherein the adhesive layer is on the substrate and the micro-component and the liquid medium are on the adhesive layer. The adhesive is used for adhering one side of the micro-component and another side of the micro-components is disposed with is disposed with the liquid medium. Then, the another side of the micro-component which is disposed with the liquid medium touches a target area, and the substrate moves toward the target zone at a speed that is smaller than 90 ?m/s for placing the micro-component on the target zone or moves away from the target zone at a speed greater than 4370 ?m/s for picking up the micro-component from the target zone.
