Abstract

The present invention provides a transfer device and a transfer method, wherein the transfer device includes a roller made of an elastic film; two rotating parts respectively arranged at both ends of the roller for driving the rotation of the roller; An air-inflating unit communicating with the roller for inflating the inside of the stretched roller; two ends respectively connected to the two rotating parts for pushing the rotating parts to radially stretch the roller a telescopic rod, and an annular clamping piece sleeved on the end of the drum for axially stretching the end of the drum. The transfer device of the present invention uses a roller made of an elastic film to transfer the micro light-emitting device. The elastic film is extensible, and the roller is stretched by the telescopic rod and the ring clamp, so that different crystal expansion distances can be realized on the roller. , The crystal expansion process is simple and easy to operate.

Description

technical field [0001] The present invention relates to the technical field of semiconductor display, and in particular, to a transfer device and a transfer method. Background technique [0002] Micro-LED (Micro Light Emitting Diode, Micro Light Emitting Diode) technology is a new generation of display technology, of which mass transfer technology is an important part of Micro-LED manufacturing. For the technology of transferring individual Micro-LEDs from a carrier substrate to a target substrate, the primary problem to be solved by mass transfer is to change the spacing between Micro-LEDs from the spacing on the carrier substrate to the spacing on the target substrate. However, the methods for mass transfer in the prior art, such as complicated operation and high cost, are not conducive to the development of Micro-LED technology. [0003] Therefore, the existing technology still needs to be improved and developed. SUMMARY OF THE INVENTION [0004] In view of the above-...
