Abstract
A light emitting element transfer device includes a first transfer head, a second transfer head disposed below the first transfer head, a stamp disposed below the second transfer head, a tilting adjustment member which adjusts a tilting of the second transfer head and a buffer member disposed below the second transfer head to be adjacent to the stamp and protruding in a downward direction to be lower than the stamp, where the buffer member includes an elastic material, where a thickness of the buffer member is greater than a sum of a thickness of the stamp and a thickness of the light emitting element.
Claims20
A light emitting element transfer device comprising:
- a first transfer head;
- a second transfer head disposed below the first transfer head;
- a stamp disposed below the second transfer head;
- a tilting adjustment member which adjusts a tilting of the second transfer head;
- and
- a buffer member disposed below the second transfer head to be adjacent to the stamp and protruding in a downward direction to be lower than the stamp, wherein the buffer member includes an elastic material,
- wherein a thickness of the buffer member is greater than a sum of a thickness of the stamp and a thickness of the light emitting element.
A method for transferring a light emitting element, the method comprising:
- disposing a transfer device including a buffer member and a stamp on a substrate;
- lowering the transfer device to contact a lower surface of the buffer member with the substrate, wherein a thickness of the buffer member is thicker than a sum of a thickness of the stamp and a thickness of a light emitting element;
- adjusting a flatness of the transfer device to a flatness of the substrate;
- and
- pressing the buffer member to contact the substrate and to transfer the light emitting element onto the substrate, wherein the buffer member includes an elastic material, and the thickness of the buffer member becomes thinner when the buffer member is pressed.
