Claims (16)

1. An electronic device comprising:

a driving substrate, comprising a plurality of circular grooves and a plurality of rectangular grooves; and

a plurality of disc-shaped electronic components, wherein at least one disc-shaped electronic component of the plurality of disc-shaped electronic components is disposed in at least one circular groove of the plurality of circular grooves, and the at least one disc-shaped electronic component comprises an alignment element positioned on a top surface of the at least one disc-shaped electronic component;

wherein a diameter of the at least one disc-shaped electronic component is defined as R, a diameter of the alignment element is defined as r, a width of at least one rectangular groove among the rectangular grooves is defined as w, and a height of the at least one rectangular groove is defined as H, and the at least one disc-shaped electronic component and the at least one rectangular groove satisfy the condition of (R+r)/2>(w 2 +H 2 ) 1/2 .

2. The electronic device according to claim 1 , wherein the disc-shaped electronic components are disposed in the circular grooves by a fluid assembly procedure.

3. The electronic device according to claim 1 , further comprising at least one rectangular electronic component disposed in the at least one rectangular groove, wherein the at least one rectangular electronic component is disposed in the at least one rectangular groove by a pick-and-place procedure.

4. The electronic device according to claim 1 , wherein the at least one disc-shaped electronic component and the at least one rectangular groove further satisfy the condition of H/(R/2)<0.292.

5. The electronic device according to claim 1 , wherein the driving substrate comprises a plurality of unit regions, wherein the at least one circular groove and the at least one rectangular groove are disposed in at least one unit region of the plurality of unit regions.

6. A manufacturing method of an electronic device, comprising:

providing a driving substrate which comprises a plurality of circular grooves and a plurality of rectangular grooves;

disposing a plurality of disc-shaped electronic components in the plurality of circular grooves by a fluid assembly procedure, wherein at least one disc-shaped electronic component of the disc-shaped electronic components comprises an alignment element which is disposed on a top surface of the at least one disc-shaped electronic component;

wherein a diameter of the at least one disc-shaped electronic component is defined as R, a diameter of the alignment element is defined as r, a width of at least one rectangular groove is defined as w, a height of the at least one rectangular groove is defined as H, and the at least one disc-shaped electronic component and the at least one rectangular groove satisfy the condition of (R+r)/2>(w 2 +H 2 ) 1/2 .

7. The manufacturing method according to claim 6 , further comprising performing a repair step on a part of a plurality of unit regions after the disc-shaped electronic components are disposed in the circular grooves.

8. The manufacturing method according to claim 7 , wherein the repair step comprises disposing at least one rectangular electronic component in at least one of the rectangular grooves by a pick-and-place procedure.

9. The manufacturing method according to claim 6 , further comprising removing the alignment element of the at least one disc-shaped electronic component.

10. The manufacturing method according to claim 6 , wherein the at least one disc-shaped electronic component and the at least one rectangular groove further satisfy the condition of H/(R/2)<0.292.
