Abstract


OLED, the organic light emitting display , with light , power and other characteristics. As the next generation of flat panel displays , OLED to achieve practical application , you must have the relevant driver support . This paper, the other flat panel display technology used in OLED display driver control graphical display , based on the ARM11 S3C6410 embedded systems hardware platform, through the analysis of the system startup process , complete Linux-based embedded operating system migration . Include the following three aspects : Linux kernel , Boot-Loader, the root file system , embedded GUI tailoring and transplantation and compiled and linked executable file is only 2MB, greatly reduces program development board hardware resources. Through a variety of popular embedded graphical user interface performance and features for analysis and comparison Select to QT / Embedded GUI development as a platform to build an application development environment. QT build Linux-based graphical design simple , interactive graphical applications. OLED display and designed menu interface , forming a system compatible with ARM-Linux graphical interface executable file. The file system compatibility, can be transplanted into general-purpose embedded system , not because of the differences of each system and can not run. Interrupt algorithms keyboard driver , the keyboard interrupt and reuse, to achieve a resolution of the interface and adjust brightness adjustment function . Algorithm addressing a short time, so adjust the settings interface response time is greatly reduced. The project uses the ARM-Linux system to streamline resistance, combined with the optimization algorithm designed to improve the OLED graphical interface and button design operating efficiency.
