ABSTRACT:
Creation of DC fields in a liquid crystal light valve caused a DC induced transient optical phenomenon in which output brightness level undergoes a change as the DC fields are redistributed within the liquid crystal light valve. Adverse effects of the DC induced transient optical output are minimized by employing a liquid crystal material of greatly decreased resistivity, which reduces the time constant of the liquid crystal device, making it comparable to the response time of the liquid crystal material itself.
