METHOD OF ELIMINATING ENTRAINED AIR BETWEEN SUBSTRATES DURING OPTICAL BONDING

A method of forming a display article includes dispensing a material onto a first substrate, and pre-curing the material to form a dam. The method includes depositing a liquid optically clear adhesive in a first pattern onto the first substrate such that the first pattern is spaced apart from the da...

Zusammenfassung:A method of forming a display article includes dispensing a material onto a first substrate, and pre-curing the material to form a dam. The method includes depositing a liquid optically clear adhesive in a first pattern onto the first substrate such that the first pattern is spaced apart from the dam to form a coated first substrate. The method includes depositing the adhesive in a second pattern onto a second substrate to form a coated second substrate, and flipping the coated second substrate upside down. The method includes translating the coated first and second substrates towards one another to eliminate an air gap, contacting the first pattern and the second pattern at a plurality of single points, and compressing the first pattern and the second pattern to eliminate the air gap and air entrained between the coated first and second substrates.
