GPRS Traits for LED Display Screens Making efficiency reliable Transmission Control Protocol (TCP) based on features of GPRS communication so as to adjust packets transfer rates (Mbps) and use GPRS bandwidth effectively, average rates could reach to 15kbps. Supporting Transmit Data Searching and Document Resuming. It just transmits the amendment part every time so as to reduce GPRS traffic and save costs for customers. GPRS not only can transmit simple texts message but also pictures and videos. Programming Software will process videos and pictures according to the screen’s size then transmit through harmless compression and storage, making a storage cell can perform information as much as possible. The usage of LED display screens is getting wider, such as advertising LED screens, traffic LED screens, etc. However, users have to do a lot of work to update the LED displays contents due to numerous numbers and widely distribution. In order to solve this problem, our company has successfully researched and developed LED display screens control systems based on GPRS. As long as users can access the internet and find the control card which connects with GPRS, they can control display contents and achieve off-site control. In this way, users can solve problems by transmitting over a long distance and with one PC it controls multiple LED display screens.
