Self-Assembly of Hybrid Components for OLED and Flexible Displays
Introduction The market for flat panel displays is projected to reach $125 billion by 2012. Flexible displays are a fast-growing segment of this market, forecast to reach $120 billion by 2020. Cost-effective methods for low cost, high volume production of these displays at increasingly larger sizes are of interest to all major manufacturers. Technology description Researchers at the UW have developed a method for high-efficiency assembly of flexible and OLED displays. The display consists of organic or inorganic light emitting diodes fabricated on a flexible transparent plastic substrate with silicon- based driver circuitry. The method allows for integration of devices made using various fabrication technologies onto a single interconnected plastic substrate. This technique overcomes the refresh speed limitation of OLED displays resulting from the low electron mobility of the organic semiconductor. Business opportunity Besides its use in display manufacturing, this self-assembly method is widely applicable for building heterogeneous systems made of micron-scale parts produced via dissimilar, and often incompatible, microfabrication processes. Stage of development Initial data exist for this technology. A working prototype has being developed and the proof of concept demonstrated. Intellectual property position This technology is available for licensing. US and foreign patent protection is pending.
