The National Energy Technology Laboratory, on behalf of the U.S. Department of Energy (DOE) announced its selection for solid-state lighting funding opportunities. A total of fourteen projects were chosen, six of which are OLED related.
QD Vision: Quantum Dot Light Enhancement Substrate for OLED Solid-State Lighting
Summary: This project seeks to develop and demonstrate a cost-competitive solution for realizing increased extraction efficiency organic light emitting devices (OLEDs) with efficient and stable color rendering index (CRI) for SSL. Solution processible quantum dot (QD) films will be utilized to generate tunable white emission from blue emitting phosphorescent OLED (Ph-OLED) devices.
University of Florida: High Efficiency Organic Light Emitting Devices for Lighting
Summary: This project seeks to address three areas: fabrication of high efficiency white OLEDs using high triplet energy carrier transporting materials and electron transporting materials with high electron mobility to provide a good charge balance, fabrication of OLEDs with an internal scattering layer to extract thin film guide modes, and fabrication of microlens arrays to enhance the extraction of the substrate guided modes.
University of Florida: Top-Emitting White OLEDs with Ultrahigh Light Extraction Efficiency
Summary: This project seeks to demonstrate an ultra-effective (>80%) light extraction mechanism that can be universally applied to all top-emitting white OLEDs (TE-WOLEDs) and can be integrated with thin film encapsulation techniques.
Dupont Displays: Solution-Processed Small-Molecule OLED Luminaire for Interior Illumination
Summary: The project seeks to develop an SSL luminaire using low cost OLED solution-processing manufacturing techniques and high performance solution-processible small molecule materials.
Eastman Kodak: OLED Lighting Panels
Summary: The project seeks the development of lighting panel architecture based on small molecule OLED and utilizing four key technology components: internal light extraction-enhancement structure, low voltage design, stacked architecture, and fluorescent-phosphorescent hybrid emitters. The object of the proposed project is to apply these technology components to construct OLED lighting panels with efficacy (>50 lm/W) and lifetime (>20,000 h). The proposed project will focus on developing structures and processes suitable for high volume, low cost manufacturing of these OLED lighting panels.
Universal Display Corporation: High Efficacy Integrated Undercabinet Phosphorescent OLED Lighting Systems
Summary: The project seeks to develop a phosphorescent OLED undercabinet lighting fixture.
