Embodiment 1

[0027] An embodiment of the present invention provides a transfer substrate for micro-light emitting diodes, which can be used for mass transfer of micro-light-emitting diodes in the process of manufacturing micro-light-emitting diode display panels, Figure 1a with Figure 1b A schematic diagram of a side-view structure of a micro-LED transfer substrate provided in an embodiment of the present invention, as shown in Figure 1a with Figure 1b As shown, the micro light emitting diode transfer substrate provided by the embodiment of the present invention includes: a base 101 and a distance adjustment unit 102 . The base 101 has a plurality of bases 1011 arranged at intervals; the bases 1011 are used to carry the micro light-emitting diodes to be transferred; the distance adjustment unit 102 is arranged between two adjacent bases 1011 for adjusting the distance between the bases 1011 .

[0028] In the initial state of the micro light-emitting diode transfer substrate provided b...

Embodiment 2

[0045] Based on the same inventive concept, an embodiment of the present invention provides a micro-LED transfer device, the micro-LED transfer transposition includes the micro-LED transfer substrate provided in the above embodiment, and also includes a push module, the push module and the distance adjustment unit The connection is used to apply an external force to the distance adjustment unit, so that the distance adjustment unit can adjust the distance between the bases.

[0046] It should be noted that the push module can apply external force to the micro-LED transfer substrate, so that the distance adjustment unit is in a stretched or contracted state, so the distance between adjacent bases can be shortened, thereby shortening the distance between the micro-light-emitting diodes to be transferred. The distance between them can further improve the accuracy of the mass transfer of micro-light emitting diodes, and realize the high-precision mass transfer of micro-light-emitti...

Abstract

The invention provides a micro light emitting diode transfer substrate and device, which belongs to the technical field of display and can solve a problem of generally low precision of mass transfer of the existing micro light emitting diode elements. The micro light emitting diode transfer substrate comprises a base and distance adjusting units, wherein the base is provided with a plurality of pedestals arranged at intervals; the pedestals are used for bearing micro light emitting diodes to be transferred; and the distance adjusting unit is arranged between two adjacent pedestals and used foradjusting the distance between the pedestals.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a micro-light-emitting diode transfer substrate and a device. Background technique [0002] Micro light emitting diode (Micro-LED) display technology is to miniaturize and matrix traditional display devices, and use integrated circuit technology to make driving circuits, so as to realize the addressing control and individual driving of each pixel. display technology. Due to its various indicators such as brightness, life, contrast, response time, energy consumption, viewing angle and resolution, it is due to traditional display technology. And it has the advantages of self-illumination, simple structure, small size and energy saving, and is regarded as the next generation display technology. [0003] At present, in the process of manufacturing Micro-LED display panels, micro-light-emitting diodes are first formed on the transfer substrate, and then a huge amount of...
