Abstract
According to the method for controlling optical transmissions according to the present invention, in a state where particles formed of a light-blocking material, a first solvent with electro-wetting properties in which the particles are dispersed, and a second solvent which is not mixed with the first solvent are present in a space covered by an optical incident surface, the particles are mixed with the first solvent but not mixed with the second solvent, and an electric field applied to the first solvent is controlled so as to control the blocking area of the first solvent with respect to the optical incident surface and control optical transmittance.
Claims20
A device for adjusting light transmission, comprising:
- charged particles composed of a light blocking material;
- a first solvent in which the particles are dispersed;
- and
- a second solvent not being mixed with the first solvent,
- wherein the particles are mixed with the first solvent but are not mixed with the second solvent, and
- wherein light transmittance is adjusted by adjusting an electric field applied to the particles to move the particles and moving the first solvent together with the particles using a difference in movement resistance at an interface between the particles and the first solvent and that at an interface between the first solvent and the second solvent to control a blocking area of the first solvent with respect to a light incident surface.
A device for adjusting light transmission, comprising:
- charged particles composed of a light blocking material;
- a first solvent having an electrowetting property in which the particles are dispersed;
- and
- a second solvent not being mixed with the first solvent,
- wherein the particles are mixed with the first solvent but are not mixed with the second solvent, and
- wherein light transmittance is adjusted by adjusting an electric field applied to the first solvent to control a blocking area of the first solvent with respect to a light incident surface, and by adjusting an electric field applied to the particles to move the particles and moving the first solvent together with the particles using a difference in movement resistance at an interface between the particles and the first solvent and that at an interface between the first solvent and the second solvent to control a blocking area of the first solvent with respect to the light incident surface.
