Full-color led structure and preparation method of full-color led structure

A preparation method of a full-color light-emitting diode (LED) structure, comprising:

• preparing first-color light-emitting units and second-color light-emitting units on a side of a first substrate simultaneously, and disposing the first-color light-emitting units and the second-color light-emitting units in a same layer;
• preparing a third-color material layer on a side of a second substrate;
• combining the first substrate and the second substrate such that the first-color light-emitting units, the second-color light-emitting units, and the third-color material layer are disposed between the first substrate and the second substrate;
• removing the second substrate;
• and
• manufacturing partition slots, wherein the partition slots extend through at least the third-color material layer to form a plurality of third-color sublayers, and third-color sublayers among the plurality of third-color sublayers whose vertical projections on the first substrate do not overlap a vertical projection of a first-color light-emitting unit among the first-color light-emitting units on the first substrate or a vertical projection of a second-color light-emitting unit among the second-color light-emitting units on the first substrate are third-color light-emitting units.
