<p>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 (22) 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 (22) itself. The light valve may include a photoconductor (14), a light blocking layer (16) and a dielectric mirror (18).</p> |
