The invention provides a Micro LED chip transfer device and method, and the device comprises a machine table which is used for bearing and transmitting a target substrate; the temporary substrate is used for temporarily bearing the Micro LED chip; the thorn wheel comprises at least three pricking needles, and the pricking needles are used for separating the Micro LED chips from the temporary substrate and transferring the Micro LED chips to the target substrate; the pulley is used for conveying the temporary substrate; in the process of transferring the Micro LED chip, the thorn wheel and the pulley are located above the machine table and located on the side, away from the Micro LED chip, of the temporary substrate. By adopting the transfer device provided by the invention and implementing the transfer method provided by the invention to transfer the Micro LED chips, the transfer efficiency of millions of chips per hour can be achieved, and the transfer efficiency of the Micro LED chips is improved, so that the production efficiency of a Micro LED display screen is improved, and the production cost is reduced.
Description
technical field [0001] The present application relates to the field of display, and in particular, to a transfer device and transfer method of a Micro LED chip. Background technique [0002] Micro Light Emitting Diode (Micro LED) displays have always been the focus of research in the display field due to their advantages of high brightness, high contrast, high color gamut, high efficiency, and high reliability. [0003] However, since the Micro LED display needs to transfer millions of Micro LED chips to the array substrate through mechanical transfer and other means during the production process, the transfer efficiency of this transfer method is low, resulting in the production efficiency of the Micro LED display. Low and high production cost. SUMMARY OF THE INVENTION [0004] The present invention provides a transfer device and transfer method for Micro LED chips, so as to improve the transfer efficiency of the Micro LED chips, thereby improving the production efficien...
