Abstract: The disclosure belongs to the field of MicroLED, and discloses a projection proximity mass transfer device. The device includes a support layer, a dynamic release layer and a adhesive foam layer. The support layer is a base layer; the dynamic release layer is arranged on the support layer. Under laser radiation, the dynamic release layer is ablated to generate ablation gas, thereby causing the dynamic release layer to generate blister; the adhesive foam layer is arranged on the dynamic release layer, and the foam layer is in contact with the MicroLED to be transferred. Under the action of thermal stimulation or laser, the foamed particles inside the adhesive foam layer expand, reducing the adhesion of the foam layer. Thereby, blisters with microstructures are formed at the interface between the stamp and the chip, thus realizing peeling of the MicroLED to be transferred.

Abstract: An electrohydrodynamic inkjet printing device, including: a support part; a jet printing module; a substrate bearing and moving module; and a roll-to-roll thin film conveying module. The jet printing module is disposed on the support part and includes a nozzle for ejecting printing fluid onto a substrate for pattern printing. The substrate bearing and moving module is disposed on the support part, and fixedly bears a rigid substrate as the substrate for pattern printing, and drives the rigid substrate to move with respect to the jet printing module. The roll-to-roll thin film conveying module is disposed on the support part, and transfers a flexible thin film as the substrate for pattern printing, and drives the flexible film to move with respect to the jet printing module.
