Paper Abstract

Using commercially available liquid crystal displays, through redesigning the drive circuit of the LCD, the dynamic range for phase-only modulation is enlarged, and the linearity of the phase response to the addressing voltage is getting better. In this paper, liquid crystal screen driving and controlling circuit principle and designing ideas have been demonstrated, and the principle figure has also been given. Using complex programmable logic device, we completed the entire circuit kernel control problem, and using the circuit to drive and control liquid crystal screen, we attained the experimental results that the maximum phase shift is proximately 1.5π.
