Optically transparent heat-activated adhesive for bonding the display panel

Method of making a display assembly, including (a) to form a laminate, the step of stuck a first substrate and a second substrate with an optically transparent heat-activated adhesive. Each of the first and second substrate has a main surface on the opposite side. At least one of the first substrate and the second substrate, or having a three-dimensional surface topography that covers at least a portion of one principal surface of its major surfaces, or those prone to deviation. In the thermal activation temperature, the adhesive is a pressure sensitive. The method also includes the step of heating the laminate to thermal activation temperature of the adhesive flowing adhesive. Activation temperature is 40 ° C. super big fewer than 120 ° C.. .FIELD 1
