Abstract
Method of and apparatus for depositing a spacer on a substrate is provided. The invention includes depositing a first ink including an adhesive agent on a first area of the substrate and depositing a second ink including supporting elements on a second area of the substrate, the second area greater than and encompassing the first area. A portion of the second ink evaporates such that the supporting elements within the second ink migrate into the first area and bond to the adhesive agent in the first ink, forming a spacer. Numerous other aspects are provided.
Claims13
A method of depositing a spacer on a substrate comprising:
- depositing a first ink including an adhesive agent on a first area of the substrate;
- and
- depositing a second ink including supporting elements on a second area of the substrate, the second area encompassing the first area;
- wherein a portion of the second ink in the second area evaporates such that the supporting elements within the second ink migrate into the first area and bond to the adhesive agent in the first ink, forming a spacer.
A method of depositing a plurality of spacers on a substrate comprising:
- depositing a first ink including an adhesive agent on a plurality of first areas of the substrate;
- and
- depositing a second ink including supporting elements on a plurality of second areas of the substrate, each of the second areas greater than and encompassing one of the first area;
- wherein a portion of the second ink in each of the second areas evaporates such that the supporting elements within the second ink migrate into the first areas and bond to the adhesive agent in the first ink, forming spacers.
