Abstract: The technique of TFT-LCD is an advanced technique which comes from the technique of micro-electronics and LCD. The TFT- LCD represents a new technique ages which is more glorious than the ages of CRT .The language of MATLAB and the Simulink environment is a set of software system. The system faces to theories analysis and engineering design. And its function is very strong. Now it has become the most extensive engineering calculation software. It supports continuous time, discrete time, and line and unline system. So it is applicable to the imitation of the electronics system by computer specially. The function of decode is very important. Its function is changing the composite video signal into R G B signals. Here I imitate the decode circuit using MATLAB language and Simulink dynamic simulation.
Key words: TFT-LCD ; decode; MATLAB; Simulink
