To solve the tedious updating problem of the display of LED screen, a remote word and screen con- trol system based on web and mini2440 was developed. This system can update the display of the LED screen through the Internet. It uses the common control cards with RS232 serial ports and has the advantages of easier contents updating,low costs of working and remote updating. And it is much easier for users to control the up- dating and display of many LED screens.
