Abstract

The invention discloses a transfer substrate, a driving backboard, a transfer method and a display device, and the transfer substrate comprises a base material, a plurality of light emitting diodes located on the base material, and a plurality of connection structures located between the adjacent light emitting diodes. The connecting structures are used for connecting the adjacent light emitting diodes, the plurality of connecting structures respectively correspond to the alignment structures on the driving back plate, and the plurality of connecting structures are used for aligning with the corresponding alignment structures in the transferring process of the light emitting diode. According to the transfer substrate Provided by the embodiment of the invention, the plurality of light emitting diodes can be connected into a whole through a plurality of connecting structures; in the transferring process of the light-emitting diodes, the light-emitting diodes are not prone to being lost and abraded; and, in the transferring process of the light-emitting diodes, alignment can be conducted through the multiple connecting structures and the corresponding connecting structures, the light-emitting diodes are aligned with the corresponding driving electrode set, the alignment precision is improved, dislocation is reduced, and the transferring yield of the light-emitting diodes is increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a transfer substrate, a driving backplane, a transfer method and a display device. Background technique [0002] Due to the advantages of self-illumination, simple structure, small size and energy saving of micro light emitting diode (Micro LED), micro light emitting diode display technology will become the next generation of revolutionary technology. Specifically, the power consumption of Micro LED display is only 10% of a liquid crystal display (Liquid Crystal Display, LCD) is 50% of an organic light-emitting diode display (Organic Light-Emitting Diode, OLED). In addition, compared with OLED displays, which are also self-luminous displays, under the same power, the screen brightness of Micro LED displays is three times higher than that of OLED displays, the display color gamut is as high as 120%, and it has better material stability. sex and no image sticking. [0003] Due t...
