专利汇可以提供Optical display device专利检索，专利查询，专利分析的服务。并且A selectively changeable composite optical display having a transparent solid layer, a flexible layer spaced therefrom having a given color or white or black, and an opaque quasi-liquid layer interposed and contained between the layers. The opaque layer has a contrasting color to that of the flexible layer or black or white. At least one rigid element having the shape of a desired alpha-numeric or other representation is impressed upon the flexible layer until that layer contacts the solid transparent layer according to the desired representation. This forces away the opaque quasi-liquid in the impressed areas and exhibits the representation for viewing through the transparent solid layer. In the un-actuated state the opaque quasi-liquid is a continuous volume that blocks the elastic layer from view.，下面是Optical display device专利的具体信息内容。

权利要求

1. A selectively changeable optical display, comprising; a. a transparent solid layer (1), b. a coextensive flexible layer (2) spaced from said solid layer, said flexible layer having a given reflectance property, c. an opaque quasi-liquid layer (3) interposed exclusively between said solid layer and said flexible layer, said opaque layer having a reflectance property optically contrasting to said given reflectance property, and d. selectable external means to bear (4) upon selected portions of said flexible layer to correspondingly displace said opaque layer, whereby the contrasting reflectance property of said flexible layer is selectively displayed for viewing through said solid layer.

2. The display of claim 1 in which; a. said given reflectance property is white, and b. said contrasting reflectance property is black.

3. The display of claim 1 in which; a. said given reflectance property is black, and b. said contrasting reflectance property is white.

4. The display of claim 1 in which; a. said given reflectance property is a color, and b. said contrasting reflectance propertY is substantially a complementary color to said color.

5. The display of claim 1 in which; a. said flexible layer is peripherally sealed to said solid layer to contain said opaque layer.

6. The display of claim 1 which additionally includes; a. electrical means (5) to actuate said means to selectively bear (4) upon said flexible layer.

7. The display of claim 1 in which said means to selectively bear (4) is comprised of; a. a rigid member having appreciable length parallel to said flexible layer, and b. electromagnet drive means attached to said rigid member on the side thereof away from said flexible layer to invariably move said rigid member toward said flexible layer.

8. The display of claim 1 in which; a. said means to selectively bear (4) is stationary, and b. the layered structure (1,2,3) is movable.

9. The display of claim 1 in which; a. said flexible layer is an elastomer of the group consisting of neoprene, polyurethane and silicon rubber.

10. The display of claim 1 in which; a. said transparent solid layer (1) is a glass-like plastic in the group consisting of methyl methacrylate and polystyrene.

11. The display of claim 1 in which; a. the opaque layer (3) is formed of a silicone fluid, and b. a pigment having the characteristics of zinc oxide.

12. The display of claim 1 which additionally includes; a. a rigid backing plate (7) disposed adjacent to said flexible layer (2) on the side away from said quasi-liquid layer (3) to generally support said flexible layer (2).

13. The display of claim 1 in which; a. the transparent solid layer (1'') has a cylindrical shape, and b. said flexible layer (2'') surrounds said solid layer, over said quasi-liquid layer.
