Abstract: One of the important parts of LED display is the circuit for scanning controls. Its main functions of receiving signals sent from video display module and transforming them into data with gray scale, as well as generating time series controlled signals are presented. A new method for gray scanning and scanning controlling circuit design is given and analyzed.
