Abstract: Apparatus and methods for improved light extraction from top-emitting OLEDs used to form displays include an array of light-emitting apparatus (60) each having the OLED (32) and a light-extraction apparatus (64) that includes an index-matching layer (70) and a tapered reflector (51). The tapered reflector (51) has the form of an inverted truncated pyramid, with the narrow end (58) interfacing with the OLED (32) through the index-matching layer (70). Light from the OLED undergoes total internal reflection within the tapered reflector (51) at the tapered reflector side surfaces (56) and is directed toward the top surface (54) of the tapered reflector (51). This light falls within the escape cone (59) of the top surface (54) and so exits the top surface (54). The OLED display (30) has a substrate that supports an array of OLEDs (32) and also includes an array of the tapered reflectors (51) operably arranged with respect to the OLEDs (32), and an encapsulation layer (100) atop the tapered reflector array.

Abstract: Embodiments of the present disclosure relate generally to methods of forming a laminate structure. In one or more embodiments, the method includes situating an interlayer between a glass substrate and a non-glass substrate having a softening point to form an assembled stack, heating the assembled stack to a temperature in a range of greater than the Tg of the interlayer to less than the softening point of the non-glass substrate and applying a force to at least one of the laminate glass surface and the laminate non-glass surface to bond that counter-balances thermal stress and polymer cure forces during bonding and prevents warpage, distortion and breakage of the laminate. In some embodiments, the interlayer has a coefficient of thermal expansion (CTE) at least 10 times greater than the CTE of the glass substrate.
