Abstract
Methods and devices for using liquid optically clear adhesives (LOCAs) are described. A method for detecting uncured LOCA between a first substrate and a second substrate is described. In addition, an improved method for curing a laminated stack up having LOCA between a first substrate and a second substrate is described. The method includes a pre-curing method involving variable exposure of the LOCA. In addition, an improved light emitting diode (LED) unit assembly for exposing a laminated stack up to ultraviolet (UV) light during a pre-curing process is described. A method for testing the LED unit assembly prior to a pre-curing process is described.
