Abstract
In order to help the transportation enterprises strengthen their competitiveness, this study proposed a digital photo frame which based on the ARM9 family processor chip S3C2440, Linux operating system and Qt/Embedded, trying to make it different from the traditional frames in terms of function, capacity and operability. It focuses on the hardware circuit and the pivotal part of software which can successfully realize playing many formats of photos like magic lantern by the touch screen and audio files. The result of the experiment shows that the digital photo frame designed in the thesis works steadily, and it is easy to operate as well as it has strong expansibility. By adding some applications to the digital photo frame, it can complete many other functions.
