OLED照明及其关键技术

有机电致发光二极管(organic light-emitting diodes,OLED)在过去十多年中间获得了长足的发展,有望成为下一代高效固态光源。器件结构的改进和优化,新型材料的设计和合成以及电致磷光材料的普遍使用,使得目前WOLED的能量效率已经超过了传统的白炽光源。指出了OLED研究中的主要技术瓶颈,并对OLED技术在照明领域面临的机遇和挑战做出评述。     

Design on general development platform for FPD systems

In this paper, a multi-functional development platform for flat panel display (FPD) development is proposed. With the proposed development platforms, a variety of FPD devices, including organic light-emitting diode (OLED) screens, liquid crystal display (LCD) screens with touchscreens, OLED microdisplay screens, etc., can be directly and instantly connected, examined and utilized. A field-programmable gate array (FPGA) is used in the development system to drive different types of FPD devices, and ARM11 S3C6410 is used as the application processor to provide various services. The development system uses Linux as the system kernel, Qt for Embedded Linux as the UI framework, various system libraries for video and audio services, and a custom-made user engine for fine-polished appearance and behavior. The development platform has been used not only in testing and verification of the FPD devices, but also in building OLED-powered handheld digital devices, shortening the development cycle from OLED devices to mature application products.
