[5] Decreasing the temperature, two regimes are successively observed: i) a one-dimensional regime where the physics of the electron gas presents a lack of quasi-particle states at the Fermi energy accompanied by the existence of separate collective modes for spin and charge degrees of freedom: a) J. Voit, Rep. Prog. Phys. 1995, 58, 977; and ii) a temperature domain where interchain couplings become relevant leading to long range ordered phases: b) T. Lorenz, M. Hofmann, M. Grüninger, A. Freimuth, G. S. Uhrig, M. Dumm, M.

We have developed a novel color patterning method for the fabrication of large format full‐color OLEDs. Laser Induced Thermal Imaging (LITI) is a laser addressed high resolution thermal patterning process with unique advantages such as excellent transfer film thickness uniformity, multilayer stack transfer ability, and scalability to large‐size mother glass. LITI patterning of small molecule materials produces OLEDs that are comparable in performance to conventional evaporated devices. Using the technology, we fabricated 2.2″ full color active matrix OLEDs.

We have developed a new color patterning method for the patterning of full color polymer light-emitting devices. Laser Induced Thermal Imaging (LITI) involves the imagewise exposure of a thermal transfer film with a scanning near infrared laser. During the process, light emitting polymer (LEP) is transferred from a thermal film to a circuitized substrate. Using the technology, we fabricated a 3.6" QVGA full color active matrix polymer light-emitting device (PLED).

In this paper, we describe a novel color patterning method for the fabrication of high resolution and large format full-color AMOLEDs. Laser Induced Thermal Imaging (LITI) is a laser addressed thermal patterning technology with unique advantages such as excellent transfer film thickness uniformity, multi-layer stack transfer ability, high resolution and scalability to large-size mother glass. We developed and optimized transfer films, structure of OLED layers, and scanning conditions for the patterning of the evaporated small molecules. As a result, we achieved excellent LITI device stability, which gave the device life time is more than 20,000 hrs with 2.0" QVGA device architecture for 150 cd/m 2 white brightness. As a first step toward the mass production, we set up Gen 4 LITI pilot system.
