Abstract:
1. A method of forming a micro-lens array, comprising: patterning a first set of micro-lens material onto a substrate; reflowing the first set of micro-lens material under first reflow conditions; curing the first set of micro-lens material to form a plurality of first micro-lenses; patterning a second set of micro-lens material onto the substrate; reflowing the second set of micro-lens material under second reflow conditions that are different than the first reflow conditions; curing the second set of micro-lens material to form a plurality of second micro-lenses; and wherein the second reflow conditions differ from the first reflow conditions in one or more of an exposure of the micro-lens material, a bleaching dosage of the micro-lens material, and a pre-treatment of the micro-lens material to change its glass transition temperature.
