The experiments presented show the response of a liquid crystal shutter to applied electric voltages and the delay of the operations. Both properties are important for liquid crystal displays of computers and television sets. Two characteristics of the shutter are determined: (i) the optical transmittance versus applied voltage of various frequencies and (ii) the time delay of the shutter operations. A common oscilloscope or a data-acquisition system displays the measurement data. The experiments are useable as classroom demonstrations.
