With the continuous development of information technology, embedded systems are increasingly being applied to a wide range of aerospace, consumer electronics, communications equipment and other fields. And in the embedded system, display system is an indispensable part in the Human-computer exchange. In recent years, with the continuous improvement of microprocessor performance, in particular the emergence of ARM processor family, the function of embedded systems are becoming increasingly powerful. This article briefly introduced the ARM7 architecture, LPC2290 internal structure and features, and then described the color LCD display system’s hardware and software design principles ideas and methods which based on the ARM processor. With an emphasis on the color liquid crystal display driver circuit system design, driver design and the Application Programming under UC / OS.
