Sub-electrode microlens array for organic light emitting devices
Patent
·
OSTI ID:1893044
Substrates are disclosed that include an embedded or partially-embedded microlens array. Devices are disclosed that include an OLED disposed over a substrate having an embedded or partially embedded micro lens array. Devices as disclosed herein redirect up to 100% of the light that otherwise would be confined in organic and electrode layers toward the substrate and thus provide improved light extraction and device efficiency.
