Abstract
A transfer apparatus includes: a body portion; and an adhesive portion connected to the body portion, with which a point light source of a display apparatus is attachable to and detachable from the transfer apparatus by contact therewith. The adhesive portion is defined by a plurality of surfaces in different planes from each other.
Claims7
A method of transferring a point light source, the method comprising:
- positioning an adhesive portion of a transfer apparatus on a carrier substrate with a point light source provided in plurality on a single planar surface thereof, wherein the adhesive portion is defined as a non-planar surface;
- applying pressure to the transfer apparatus to adhere the plurality of point light sources on the single planar surface of the carrier substrate to the non-planar surface of the adhesive portion of the transfer apparatus;
- separating the plurality of point light sources adhered to the adhesive portion of the transfer apparatus from the single planar surface of the carrier substrate;
- positioning the transfer apparatus with the plurality of point light sources adhered to the adhesive portion of the transfer apparatus on a display substrate of a display apparatus;
- and
- separating the plurality of point light sources adhered to the adhesive portion of the transfer apparatus from the transfer apparatus to transfer the plurality of point light sources to a surface of the display substrate.
