A novel driving system for high performance true color FED

This paper presents a novel driving system of a 5 inch true color FED using a voltage controlled PWM method with a current control effect. The proposed method has the advantage of both the voltage controlled pulse width modulation method and current control method. We propose an effective circuit model of a FED subpixel for circuit simulation of FED driving circuits. The output stage of the data driving circuit is optimized using the proposed circuit model. In video data processing, the FED controller uses the parallel processing of RGB input data, so the duty ratio increases. With these results, no noise and high quality performance is achieved in a 5 inch true color FED.
