<p>An antifogging perspective screen includes two transparent thin plates which are opposed to each other in a parallel relationship, between which is formed a sealed space filled with liquid, with a surface heating device being arranged on the bottom of one of the thin plates. The invention transforms electric energy into heat energy by providing the surface heating device on the bottom of the transparent thin plate so as to make the liquid to forming a convection due to the temperature increment. The liquid fluxion between the two thin plates leads to the temperature of the plates raising so as to prevent the fog forming on the screen. The invention is applicable to a inside television which is arranged in a bathroom, shower compartment and sauna room and a outside closed-circuit television, a store window, a windshield in the car and the like.</p> |
