Abstract

The invention discloses a method of transferring a micro light emitting diode, a display device and a piece of electronic equipment. The method of transferring a micro light emitting diode comprises the following steps: providing a substrate, wherein the substrate is provided with a first accommodating slot used for accommodating a first micro light emitting diode; depositing a positively chargedpolymer film on the supported surface of the first micro light emitting diode and depositing a negatively charged polymer film on the supporting surface of the first accommodating slot, or depositinga negatively charged polymer film on the supported surface of the first micro light emitting diode and depositing a positively charged polymer film and a negatively charged polymer film on the supporting surface of the first accommodating slot; and transferring the first micro light emitting diode to the substrate to enable the first micro light emitting diode to fall into the first accommodatingslot under the electrostatic attraction between the positively charged polymer film and the negatively charged polymer film. Through the technical scheme of the invention, the transfer process of themicro light-emitting diode is simplified, and the process cost is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for transferring micro-light emitting diodes, a display device and electronic equipment. Background technique [0002] Micro-light-emitting diode display technology is a self-luminous display technology. Through the structure of thin-film, miniaturized and arrayed light-emitting diodes, the volume of light-emitting diodes is reduced to at least 1% of the original volume. It has low power consumption, high brightness, and high resolution. High efficiency, high color saturation, fast response, long service life and other characteristics, the development potential has attracted much attention. In the process of the commercialization of micro-light-emitting diodes, the key lies in how to realize "massive grain transfer", that is, how to transfer a large number of micro-light-emitting diodes to the substrate. In the prior art, micro-electromechanical systems (MEMS) are usua...
