    摘要: A screen has a screen main body, a power supply and a voltage regulator. The screen main body has a Fresnel lens, a polymer dispersed liquid crystal unit and a lenticular lens. The liquid crystal unit includes a polymer dispersed liquid crystal and a pair of transparent electrodes which sandwich the polymer dispersed liquid crystal. By operating the voltage regulator, a voltage applied to the electrodes is adjusted so that a gain of the liquid crystal is controlled.
