| Abstract: | According to the requirements of synchronous display system with large and full-color LED,the composition of control system is first discussed,and then the design scheme is determined, which adopts DVI as data interface and uses serial LVDS as transmission module. A data recombination method is used and an innovative frequency conversion algorithm is proposed for field division scan,and therefore field division display without brightness loss is realized. The simulation results of key modules show the feasibility of the system design. |
