Title:
TRANSFER UNIT OF MINIATURE LIGHT-EMITTING DIODE, DISPLAY MODULE AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/114028
Kind Code:
A1
Abstract:
The present invention provides a transfer unit. The transfer unit is mounted on a back plate. The transfer unit comprises a light-emitting unit having at least two miniature light-emitting diodes, a light barrier layer covering the periphery of the light-emitting unit, and a light-emitting area and a binding area which are exposed at the light barrier layer and located at two ends opposite to the light-emitting unit. The at least two miniature light-emitting diodes are fixed together and emit two paths of monochromatic light of the same color, and the at least two miniature light-emitting diodes form a positive electrode and a negative electrode; the two paths of monochromatic light are emitted from the light exiting area, the positive electrode and the negative electrode are respectively located at one side of the light exiting area and one side of the binding area, or both the positive electrode and the negative electrode are located at one side of the binding area, and the binding area faces the back plate. In addition, the present invention also provides a display module and a display device using the transfer unit.
