Abstract
A method is disclosed for encapsulating at least one display device. A plurality of parallel openings are formed in a first material layer on a first substrate to expose a second material layer underneath. A predetermined sealant is placed thereon to form a sealant region perpendicular to the openings for attaching a second substrate, wherein the sealant contacts the first material layer and the second material layer through the openings for encapsulating the display device between the first and second substrates.
Claims20
A method for sealing at least one display device, the method comprising:
- forming a plurality of parallel openings in a first material layer on a first substrate to expose a second material layer underneath;
- and
- placing a predetermined sealant thereon to form a sealant region perpendicular to the openings for attaching a second substrate,
- wherein the sealant contacts the first material layer and the second material layer through the openings for sealing the display device between the first and second substrates.
A sealant region for sealing at least one display device, the sealant region comprising:
- a plurality of parallel openings in a first material layer on a first substrate to expose a second material layer underneath;
- and
- a predetermined sealant placed thereon to form the sealant region perpendicular to the openings for attaching a second substrate,
- wherein the sealant contacts the first material layer and the second material layer through the openings for sealing the display device between the first and second substrates, and
- wherein the sealant has substantially flat contact surfaces with the first and second material layers.
A method for sealing at least one display device, the method comprising:
- forming a sealant region having one or more openings having a predetermined pattern by removing portions of a first material layer on a first substrate to expose a second material layer underneath;
- and
- placing a predetermined sealant in the openings for attaching a second substrate with the first substrate,
- wherein the sealant in the openings is balanced along a center axis of the sealant region.
A method for sealing at least one display device, the method comprising:
- forming a sealant region having at least one opening having a predetermined saw teeth pattern by removing portions of an organic material layer on a first substrate to expose a predetermined material layer underneath;
- and
- placing a predetermined sealant in the openings for attaching a second substrate with the first substrate.
