Problems solved by technology

[0003] At present, when preparing Micro LED displays, it is necessary to transfer a large number of micro-scale Micro LEDs to the array substrate. Before transferring the Mirco LED monomers, they need to be precisely oriented. However, there is currently no method for large-scale micro-LEDs. It is an effective means for directional arrangement of high-level micro-components and to ensure the yield rate of the arrangement. Especially for high-resolution displays, millions of micro-LED chips need to be arranged, which is more difficult and time-consuming.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a Micro LED inkjet printing device, a transfer method, a display panel, and a display device. Background technique [0002] Micro LED (Micro LED) is a miniaturized LED array structure with self-luminous display characteristics. Its technical advantages include all-solid-state, long life, high brightness, low power consumption, small size, ultra-high resolution, and can be applied to high temperatures or extreme environments such as radiation. Compared with OLED technology, which is also a self-luminous display, Micro LED not only has higher efficiency and longer life, but the material is not easily affected by the environment and is relatively stable, and it can also avoid the phenomenon of afterimage. [0003] At present, when preparing Micro LED displays, it is necessary to transfer a large number of micro-scale Micro LEDs to the array substrate. Be...
