| Abstract: | A detailed introduction on the principle and circuit structure of multi-function scancontrol for large-screen display device is given.The multi-function of single CPU and Master-Slaverworking mode are considered.Some methods for improving brightness and stability of display are al-so presented. Some advanced technology improving effeciency of CPU,enhancing controling capabil-ity for pixel and bus wth time-shared function are adopted. This system pays attention to coordina-tion of both hardware and software in order to ensure reliability and high-speeded procession. |
