Preventing stress transfer in OLED display components
View Patent ↗An OLED display, comprising: a substrate; an OLED having two spaced-apart electrodes and organic layers disposed there between, and the OLED disposed over the substrate; an encapsulation container fixed by perimeter seal to the substrate and disposed over the OLED to provide an enclosure; and the substrate or the encapsulation container, or both, including compliant regions that flex, compress, or expand under stress and reduce stress transfer between the substrate and the encapsulation container through the perimeter seal.
1. An OLED display, comprising:
a. a substrate;
b. an OLED having two spaced-apart electrodes and organic layers disposed there between, and the OLED disposed over the substrate; and
c. an encapsulation container fixed by a perimeter seal to the substrate and disposed over the OLED to provide an enclosure, a flexible foil located in a portion of the encapsulation container that is opposite and substantially parallel to the substrate surface;
wherein the encapsulation container includes compliant regions provided by spaced-apart bends in the flexible foil, such compliant regions providing flexibility, compressibility, or expandability under stress to thereby reduce stress transfer between the substrate and the encapsulation container through the perimeter seal.
2. An OLED display, comprising:
a. a substrate;
b. an OLED having two spaced-apart electrodes and organic layers disposed there between, and the OLED disposed over the substrate; and
c. an encapsulation container fixed by a perimeter seal to the substrate and disposed over the OLED to provide an enclosure;
wherein the substrate is formed of a flexible material and includes compliant regions provided by spaced-apart bends or flexures in the substrate, such compliant regions providing flexibility, compressibility, or expandability under stress to thereby reduce stress transfer between the substrate and the encapsulation container through the perimeter seal.
