Title: Devices combining thin film inorganic LEDs with organic LEDs and fabrication thereof

Abstract

Devices including organic and inorganic LEDs are provided. Techniques for fabricating the devices include fabricating an inorganic LED on a parent substrate and transferring the LED to a host substrate via a non-destructive ELO process. Scaling techniques are also provided, in which an elastomeric substrate is deformed to achieve a desired display size.
