Abstract:
A spherical LED chip, a method for manufacturing the same, and a display panel, and a method for spherical LED chip transfer are provided. The spherical LED chip includes a first electrode, a second electrode surrounding the first electrode and having magnetism, and a first insulating protective layer arranged at the outside of the first electrode. The first insulating protective layer and the second electrode form an LED housing configured to wrap the first electrode and with a spherical outer contour.
