Pixel structure having repairing light emitting diode die and extending conductor, manufacturing method of pixel structure, and display having pixel structure

A manufacturing method of a pixel structure, comprising:

• providing an original light emitting diode die, the original light emitting diode die comprising a first epitaxial layer, a first electrode and a second electrode, the first electrode and the second electrode being disposed at opposite sides of the first epitaxial layer, and the second electrode being at least partially exposed outside;
• forming an extending conductor, the extending conductor comprising a first portion and a second portion, the first portion being electrically connected to the second electrode of the original light emitting diode die;
• detecting whether the original light emitting diode die is normal;
• and
• if the original light emitting diode die is detected as abnormal, disposing a repairing light emitting diode die, and cutting off an electrical communication path of the first portion corresponding to the extending conductor, wherein a color of light emitted by the repairing light emitting diode die is the same as a color of light emitted by the original light emitting diode die, the repairing light emitting diode die comprises a second epitaxial layer, a third electrode and a fourth electrode, the third electrode and the fourth electrode are disposed at a same side of the second epitaxial layer and in direct contact with the second epitaxial layer, and the step of disposing the repairing light emitting diode die comprises electrically connecting the third electrode of the repairing light emitting diode die to the second portion of the extending conductor.
