[0009] Recently, in U.S. Patent No. 9,825,202, micro-LED structures suitable for self-assembly have been proposed, but research on the technology of manufacturing displays through self-assembly of micro-LEDs is still insufficient
[0010] Especially, in the case of rapidly transferring millions of semiconductor light emitting devices to a large display in the related art, the transfer speed can be increased, but there is a problem in that the transfer error rate may increase, resulting in lower transfer yield Rate
On the other hand, in the case of trying to improve the transfer yield by reducing the transfer defect rate, there is a problem in that the transfer speed decreases
Therefore, there is a technical contradiction between transfer speed and transfer yield

Description
technical field [0001] Embodiments relate to integrated assembly and transfer apparatus for semiconductor light emitting devices. Specifically, the embodiment relates to an intelligent integrated assembly and transfer device of a semiconductor light emitting device, which can not only increase the transfer speed but also improve the transfer yield by integrally performing the assembly and transfer when transferring the semiconductor light emitting device into a display panel Rate (yield). Background technique [0002] Technologies used to realize large displays include liquid crystal displays (LCDs), OLED displays, and micro-LED (micro-LED) displays. [0003] Meanwhile, the micro LED display is a display using a micro LED, which is a semiconductor light emitting device having a diameter or cross-sectional area of 100 μm or less, as a display element. [0004] In addition, since micro LED displays use micro LEDs as display elements, they are excellent in many characterist...
