Abstract

The invention discloses a micro light-emitting diode display panel and a preparation method thereof, the micro light-emitting diode display panel comprises: a driving back plate, wherein one surface of the driving back plate is provided with a plurality of grooves, the bottom of each groove is provided with a first magnetic electrode, and the sectional dimensions of the grooves are gradually increased from bottom to top; and a micro light-emitting diode which is embedded into the groove of the driving back plate, wherein a second magnetic electrode is arranged at one end of the micro light-emitting diode, the second magnetic electrode and the first magnetic electrode are in contact with each other, and the maximum section size of the micro light-emitting diode is not smaller than that of the groove. In this way, the transfer efficiency of the micro light-emitting diode can be improved, and large-scale transfer is achieved.

Description

technical field [0001] The present application relates to the field of micro-light-emitting diode transfer technology, in particular to a micro-light-emitting diode display panel and a preparation method thereof. Background technique [0002] Micro LED (Micro LED) technology refers to a micro-sized LED array integrated with high density on a substrate. Micro LED is expected to lead the next generation of display technology due to its extremely high luminous efficiency and extremely long display life. [0003] Micro-LEDs are usually mass-transferred after fabrication, specifically transferring a large number of micro-LED chips to a driving circuit board to form a micro-LED array. When the current fluid assembly method transfers the micro-light-emitting diodes, because the micro-light-emitting diodes are randomly distributed in the fluid, the production efficiency of the micro-light-emitting diodes may be low. Contents of the invention [0004] The present application provi...
