Method for transmission change in welding light filter on liquid crystal base, involves accelerating molecules of liquid crystal by short-term voltage rise of degradation of transmissive arrangement
摘要
<p>The method involves accelerating the molecules of the liquid crystal by a short-term voltage rise of the degradation of the transmissive arrangement. The duration and intensity of the electric voltage are variable. The direction of the electric field is inverted after each darkening cycle.</p>
