摘要： A method for making an adsorption device includes: providing and etching a substrate to form a plurality of receiving grooves spaced apart from each other; forming a magnetic film in each of the plurality of receiving grooves; and forming a magnet in each of the plurality of receiving grooves. Each receiving groove includes a bottom wall and a side wall coupling the bottom wall. The magnetic film covers the bottom wall and the side wall of each of receiving groove.

摘要： A method for transferring a large number of light emitting elements in a single operation during display panel manufacture includes providing a receiving substrate with light emitting elements; orienting the light emitting elements on a first platform by a first electromagnetic plate; transferring the light emitting elements on the first platform to a second platform by a second electromagnetic plate; and transferring the light emitting elements on the second platform to the receiving substrate by a third electromagnetic plate. Each light emitting element undergoes a coarse positioning and finer positionings during the transfer process, so an accuracy of the light emitting elements is high.

摘要： A method for transferring light emitting elements during manufacture of a display panel includes providing light emitting elements; providing a first electromagnetic plate defining adsorption positions; providing a receiving substrate defining receiving areas; energizing the first electromagnetic plate to magnetically adsorb one of the light emitting elements at each adsorption position; facing the first electromagnetic plate to the receiving substrate; and transferring the light emitting elements to one corresponding receiving area of the receiving substrate.

摘要： An adsorption device includes a magnetic plate and a limiting layer. A surface of the magnetic plate includes a first region and a plurality of second regions spaced apart from each other. The first region and each second region do not overlap with each other. The first region forms a magnetic pole of the magnetic plate, and each second region forms the opposite magnetic pole of the magnetic plate. The limiting layer covers the first region. Each second region is exposed to the limiting layer and configured for adsorbing a small-scale LED as a target object.
