Abstract
Methods for liquid adhesive lamination for precision adhesive control are provided. Precision liquid adhesive control can be obtained by first patterning liquid adhesive in a thin pre-coat layer on a substrate. A second adhesive layer can then be patterned on top of the pre-coat layer. When the second substrate is pressed onto the first substrate, the second substrate first comes into contact with the second adhesive layer. The adhesive can then be spread uniformly across the two substrates without forming voids. Alternatively, a single liquid adhesive layer can be formed in a three dimensional gradient pattern.
