| Abstract: | This paper presents principle of grayseale modulation and design of grayscale modulation driving circuit for Field Emission Display. Function of video signal interface and pulse width modulation is realized by FPGA technology. Addressing chip is connected with serial-in parallel-out transformer, and its output PWM signals are amplified to drive the FED panel. The sample obtains 256 grayscale. |
