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 ARM11S3C6410 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.展开更多
